This document summarizes a thesis presentation on mini-fluidic solvent extraction of EPA/DHA from fish oil using silver. Key points include:
1) EPA/DHA yields above 75% were achieved in both a mini-fluidic reactor and stirred tank reactor, exceeding capabilities of current extraction methods.
2) Flow patterns in mini-channels with fish oil and silver nitrate differed from previous studies using synthetic systems and required handling stratified flow.
3) A conceptual continuous process design was presented for industrial-scale extraction with an estimated capital cost of $14.5 million for a 10 ton/day facility.
The document describes research on extracting EPA/DHA from fish oil using a mini-fluidic reactor and comparing it to a batch reactor. Key findings include:
- The mini-fluidic reactor reached equilibrium concentration at 10°C in less than 36 seconds, while the batch reactor took over 15 minutes. Both systems extracted over 75% of omega-3 fatty acids from the fish oil feedstock.
- Flow patterns in the mini-fluidic reactor deviated from the expected slug flow due to the properties of the actual fish oil and silver nitrate solutions used.
- Hydrodynamic studies showed stratified flow occurred rather than slug flow, indicating practical fish oil processing with silver nitrate may require handling stratified flows

Soni Oyekan presented on catalytic applications for enhanced production of transportation fuels. His research in the 1970s-1980s at ExxonMobil focused on platinum/rhenium catalysts. He found that adding optimal amounts of rhenium to platinum catalysts lowers coke production, increases hydrogen yield, and shifts aromatics to more valuable BTX. His development of staged and two-stage reduction techniques for platinum catalyst reactivation further improved gasoline and hydrogen yields. Oyekan's work led to commercial adoption of platinum/rhenium catalyst systems in over 120 refineries worldwide, enhancing economic returns through increased fuel production.

High-Capacity Capture of a Recombinant Growth Factor Directly From Refold Sol...MilliporeSigma
The document evaluates different cation exchange resins for capturing a recombinant human growth factor directly from a refold solution containing high salt concentrations. Testing showed the new salt tolerant Eshmuno® CPS resin had a two-fold higher binding capacity than other resins when processing the high salt refold solution. Purification trials using the Eshmuno® CPS and Eshmuno® CPX resins achieved similar purity and yield. A cost analysis found using the salt tolerant Eshmuno® CPS resin reduced costs per gram of target produced by 1.9-fold and increased productivity by 50% compared to the standard Eshmuno® CPX resin. Compared to a conventional resin requiring feed dilution, the Eshmuno®
This document summarizes a study on the analysis of the biogenic amines putrescine and cadaverine in food products using gas chromatography without derivatization. The study finds that "cold on-column" gas chromatography injection together with a base-deactivated fused silica column allows for good resolution and separation of putrescine, cadaverine, and an internal standard. Multiple injections show reproducibility of peak areas within 1% and retention times within 0.03%. Good linear response is also observed between concentrations of 20 to 400 ppm. The method provides a simple, direct means of analyzing these biogenic amines as indicators of food quality and spoilage.
Dr. Reddy's Development of Kinetic Model and Process Prediction. Keerthi Pemula.Scale-up Systems
This document discusses two case studies using kinetic modeling and DynoChem software to improve pharmaceutical synthesis processes. In the first case, three mechanisms were evaluated to predict an anti-bacterial reaction and reduce impurities. Mechanism 3 best fit the data and parameters from it improved yield. The second case developed a kinetic model for an API synthesis to minimize impurities and maximize yield through simulation and optimization. Process changes based on the mechanisms reduced reaction time and improved purity and yield. Overall, kinetic modeling with DynoChem helped analyze reaction mechanisms and improve two industrial synthesis processes.

La reutilización ha sido desde siempre uno de los objetivos más perseguidos dentro de la ingeniería del software. La idea de convertir los procesos de construcción de aplicativos en algo automatizable, sencillo y económico siempre ha estado ahí en la cabeza de los desarrolladores. Pero, de manera recurrente, esta iniciativa se ha dado de bruces con los inamovibles mimbres de unos paradigmas de programación demasiado inflexibles a este respecto.
Sin embargo, lenguajes como Javascript se prestan mucho más a hacer del desarrollo de código un ejercicio de verdadera reutilización. A lo largo de esta charla explicaremos cuáles son las barreras paradigmáticas que suelen impedir la reutilización y cómo y en qué sentido JavaScript consigue soslayarlas con éxito. Asimismo presentaremos una colección de modelos arquitectónicos basados en Mixins, Traits, Roles, Aspectos, Subjects, etc. que se están usando en proyectos de software actuales con este lenguaje precisamente por las bondades que ellos.

The document discusses using minifluidic channels as an alternative process for extracting Omega-3 PUFA from fish oils. The preliminary experiments were conducted in Tygon tubing, but it was found to soften over time when exposed to fish oil esters. Larger scale experiments will use a plate and frame design constructed of a suitable material. Minifluidic channels offer improved mixing, a higher surface area to volume ratio, and reduced solvent usage compared to conventional extraction processes. Experimental results show the extraction yield from minifluidic channels is satisfactory compared to batch stirred tank reactors. Further development of the minifluidic extraction process design and scale up is ongoing.

Microbial catalysis of syngas fermentation into biofuels precursors - An expe...Pratap Jung Rai
Search for environment-friendly sustainable energy sources is of global interest due to continuous depletion of fossil fuels resources and excessive carbon dioxide emissions. Syngas fermentation is one of the promising sustainable alternative for liquid biofuel and chemical production from energy content wastes/byproducts. This study mainly focuses on acetic acid and ethanol production via fermentation, using hydrogen and carbon dioxide as substrates to mimic syngas. A laboratory scale, batch fermentation was performed at different headspace pressure ranged from 0.29 to 1.51 bar, 1200 rpm stirrer speed, and 22±1.4ºC.
Formation of acetic acid and ethanol were found significant. The maximum acetic acid concentration 68 mmol/L was obtained at 1176 hours and 1.12 bar headspace pressure. However, maximum ethanol concentration of 15 pA*s was found at 1297 hours and 1.51 bar headspace pressure. Ethanol consumption was observed during first 553 hours. Maximum H2 consumption rate was 0.153 mmol/h•gVS during 478-527 hours at 1.12 bar headspace pressure, which was 51 times higher than that obtained during first 71 hours at 0.29 bar headspace pressure (0.003 mmol/h• gVS). The total consumed hydrogen gas measure as COD (CODHydrogen) was equivalent to the increase in bulk liquid COD, 11.02 gCOD and 11.44 gCOD; in which 68% of CODHydrogen was converted to acetic acid (7.44 gCOD). A significant influence of headspace pressure and dissolved hydrogen concentration were observed on the volumetric mass (H2) transfer coefficient (kLa) and the solubility of hydrogen in the inoculum (CH). The maximum kLa and CH of 0.082 h-1 (R2 = 0.995) and 1.2 10-3 mol/L were found at 1.12 bar headspace pressure and 89 mmol/L dissolved hydrogen concentration, respectively. The calculated biomass yields ranged from 0.001-0.066 and 0.001-0.059 gVSS/gCOD, for acetic acid and ethanol formation, respectively, when the assumption of free energy efficiency use in growth was changed from 0.1 to 1.
Acetic acid and ethanol were dominant final product whereas other organic acids were almost constant and insignificant throughout the experiment. This implies that the microbial fermentation of hydrogen and carbon dioxide at headspace pressure ranged from 0.29-1.51 bar, 1200 rpm stirrer speed, and 22±1.4ºC, can be performed with digested food waste sludge for efficient acetic acid and ethanol production.

TIME SAVING ELECTRO-OXIDATION TECHNOLOGY FOR TREATING PRODUCED WATERwle-ss
This document discusses analyzing and treating flowback water for reservoir characterization and production optimization. It outlines how flowback data and samples can be used to learn about water-rock interactions and their effects on wettability and permeability. Various treatment methods are examined, including electro-oxidation to alter wettability from oil-wet to water-wet. Laboratory coreflood experiments show treated brine can increase oil recovery compared to untreated brine. The goal is to optimize fracturing processes to improve long-term well productivity through enhanced oil recovery while fracturing.
This document discusses chemical EOR methods including surfactants and polymers. Surfactants are used to lower interfacial tension between oil and water, change rock wettability, and generate foams or emulsions. Polymers such as HPAM increase water viscosity for mobility control. Successful polymer flooding projects can recover 5-30% of original oil in place through improved sweep efficiency. Key factors for polymer flooding include reservoir continuity, remaining oil saturation, and favorable injection conditions.

This document summarizes a project to develop a spray coating process to produce nanocellulose and nanocomposite films for packaging applications. The author worked as a process engineer to design and construct a spray coating experimental setup. Key objectives included developing a spray coating process to produce free-standing nanocellulose films of varying thickness and roughness on impermeable surfaces, and nanocellulose-composite films. The author characterized the mechanical and barrier properties of the spray-coated films and found they had comparable properties to films made by vacuum filtration. The developed process provides a more rapid and flexible method for producing nanocellulose packaging films.
Spraying nanocellulose on a polished impermeable surface is a novel concept to produce a film which has two distinct surfaces. The spray coated surface is very smooth and replicates the nanoscale roughness from the base surface. This process reduces the operational time for film formation by one order of magnitude compared to vacuum filtration, which is the standard method. The spraying process was optimised to develop highly uniform sheets. The films were recyclable and sustainable. Spraying process has been successfully implemented to develop high performance nanocomposites for barrier applications and smooth films for electronics.
This document provides an introduction and literature review on nanocellulose and its composite films. It discusses nanocellulose as a novel fibrous material produced from mechanical, chemical or enzymatic defibrillation of lignocellulosic biomass. The characteristics, production methods, applications and properties of nanocellulose films are reviewed. Various fabrication methods for producing nanocellulose films and composites are critically analyzed, along with their pros and cons. The document identifies gaps in knowledge around developing rapid processes to produce high quality nanocellulose films for applications such as packaging.
NANOCELLULOSE AND ITS COMPOSITE FILMS – APPLICATIONS, PROPERTIES, PREPARATION...Kirubanandan Shanmugam
Nanocellulose (NC) is a biodegradable nanomaterial produced from lignocellulosic biomass. The mechanical, chemical or enzymatic processes are normally used for defibrillation of wood fibres into nanofibrils. It is a cellulose nanofibril with unique characteristics leading to potential applications in functional materials. These nanomaterials can replace synthetic plastics and be used as biomaterials for developing recyclable nanocomposites. The fibrils at nanosize provide high surface area and strength and are biodegradable. NC films and their composites have been used in developing functional materials such as barrier materials, substrates for printing circuits in flexible electronics, barrier coatings on the paper and paper board etc., In addition, there is a potential demand for NC films and composites to replace or eliminate conventional plastics. There are many methods available to prepare free-standing NC films with composites and these are critically reviewed and addressed in this chapter. Conventional methods are seen to be time-consuming, and unable to produce outstanding quality films, which set limitations on commercialization. Therefore, a rapid process to produce the NC films is required to meet the potentially large requirement for packaging and other functional material.
Effect of Recycling of Nanocellulose on their barrier properties and mechanic...Kirubanandan Shanmugam
The document summarizes research on the effect of recycling on the barrier and mechanical properties of nanocellulose films. Nanocellulose films were made via spray coating and then recycled using dispersion and vacuum filtration. Testing found that recycled films retained 70% of the strength of virgin films and had double the water vapor permeability. Examinations across multiple length scales suggested this was due to nanofiber bundles that were not fully separated during recycling, reducing density and uniformity and thereby properties. While recycling reduced performance, barrier properties remained better than conventional cellulose packaging. Further optimization of the recycling process may be needed to fully separate nanofibers.
This document summarizes research on developing a two-layer depth filter with improved filtration performance. The researchers spray coated an anionic cellulose nanofibre (CNF) layer onto a cationic depth filter base sheet. This created a filter with triple functionality: 1) the cationic base sheet could adsorb anionic molecules; 2) the anionic CNF top layer could adsorb cationic molecules; and 3) the CNF layer acted as a microfiltration membrane. Testing showed that a CNF coat weight of 8 g/m2 optimized performance, rejecting 80% of 5000 kDa polyethylene glycol at a flux of 133 LMH, while still effectively absorbing the cationic dye methylene blue.
Silver nanowires are a versatile tool for creating conductive paper. When added to paper, silver nanowires can enhance the electrical and thermal conductivity of paper without impacting its optical properties. Silver nanowires allow paper to be used in new applications that require electrical conductivity, such as touchscreens, RFID tags, flexible electronics, and biosensors.
This document investigates factors that control the roughness of nanocellulose films produced by spraying. It examines the effect of substrate surface chemistry and roughness, nanocellulose fibre diameter, and addition of carboxymethyl cellulose to nanocellulose suspensions. The three key factors found to control film roughness are: the roughness of the substrate surface, the diameter of the nanocellulose fibrils, and addition of carboxymethyl cellulose. Adding carboxymethyl cellulose, which reduces fibre-fibre friction, produced smoother films, especially when sprayed on rougher substrates. The smoothest film achieved had a roughness of 336±117nm and resulted from spraying a suspension containing 1.5%
This document summarizes research investigating the recyclability of nanocellulose films as an alternative to non-recyclable polyolefin packaging materials. Virgin nanocellulose films were recycled using standard dispersion and vacuum filtration techniques. The recycled films retained around 70% of the strength of virgin films and had a water vapor permeability that doubled but was still comparable to synthetic polymers. Scanning electron microscopy showed no fiber damage or agglomeration during recycling. The recycled films had decreased uniformity at small scales but increased uniformity at large scales compared to virgin films. The retained strength, barrier properties, and ease of reprocessing demonstrate that nanocellulose films could provide a sustainable and recyclable alternative to conventional packaging.
This document discusses a study that investigated the production of nanocellulose films using a spray coating process. The study varied parameters like conveyor speed and nanocellulose suspension concentration during spraying. It found that spray coating can efficiently produce films with basis weights ranging from 38 to 187 g/m2 and thicknesses from 58.4 to 243.2 μm. Film thickness and basis weight showed a universal linear relationship. Optical uniformity of films increased with higher conveyor speed and was maximized between 1.5-1.75% nanocellulose concentration. The most uniform spray coated films had similar tensile strength as films made through vacuum filtration. The study demonstrated that spray coating can be a more time efficient alternative
Spray Coating -A Rapid Method for preparation of nanocellulose filmKirubanandan Shanmugam
This document describes a new method for rapidly producing nanocellulose films using spray coating. Nanocellulose suspensions at consistencies ranging from 1.0-2.0% were sprayed onto stainless steel plates moving at 0.32 cm/s. Films with basis weights from 52.8-193.1 g/m2 could be produced in 1 minute, significantly faster than vacuum filtration which typically takes 10 minutes. The spray coated films had a smoother surface that was in contact with the steel plates compared to the outer surface. This spray coating technique is presented as a rapid and flexible method for producing nanocellulose films at the laboratory scale.
Spray coated nanocellulose films were investigated as a potentially sustainable alternative to synthetic packaging materials. The nanocellulose films were recycled by dispersing them in water and vacuum filtration to reform sheets. The recycled films retained 80% of their original tensile strength and maintained significant barrier properties, though water vapor permeability doubled. Scanning electron microscopy showed no fiber agglomeration or damage during recycling. The retained strength, barrier performance, and easy reprocessability of the recycled nanocellulose films demonstrates their potential as a sustainable and recyclable alternative to conventional packaging.
Spray Coating -A Rapid Method for preparation of nanocellulose filmKirubanandan Shanmugam
A spray coating technique was developed to rapidly prepare free-standing nanocellulose films in under 1 minute by spraying a nanocellulose suspension onto a moving stainless steel plate, which was then air dried under restraint. The produced films had a basis weight that varied between 50 and 200 g/m2 and were 15% thicker than films made through vacuum filtration, but had similar uniformity and ultra-high smoothness on the side exposed to the metal surface during drying. The significant reduction in preparation time suggests spray coating can be an alternative to vacuum filtration for quickly producing nanocellulose sheets for further investigation.
Recycled nanocellulose films were produced from virgin nanocellulose films using laboratory dispersion techniques under ISO standard conditions. While the strength and barrier performance of the recycled films were reduced compared to the virgin films, the barrier performance was still comparable to synthetic polymers like LDPE. Remarkably, the energy required to recycle the nanocellulose film waste into a nanofiber suspension was two orders of magnitude less than originally required to produce the nanofibers. This shows that recycling nanocellulose film waste is an attractive option from an energy perspective.
Effect of Recycling of Nanocellulose on their barrier properties and mechanic...Kirubanandan Shanmugam
Recycled nanocellulose films retained 70% of the strength of virgin films but had double the water vapor permeability. This was likely due to bundles of cellulose nanofibers that did not fully separate during recycling, hindering uniform packing and reducing density. At the fiber level and under high magnification SEM, recycled and virgin films were identical, but recycled films had poorer optical uniformity and strength at larger length scales. Recycling reduced barrier performance but it was still much better than conventional packaging materials. The major issue was incomplete breakdown of nanocellulose sheets into individual fibers during recycling.
This document is an abstract submission for a research showcase about tuning the nanoscale surface roughness and smoothness of nanocellulose films via spray coating. The researchers developed a new spray coating method to produce smooth nanocellulose films. The films have two-sided surface roughness, with the side in contact with the polished surface during spraying being much smoother than the air-exposed side. The roughness was measured using optical profilometry and found to be 2087 nm for the rough side and 389 nm for the smooth side. Factors controlling the roughness like cellulose fibril size and the base surface smoothness are being investigated. Surface smoothness requirements for applications like SERS and printed electronics will also be discussed.
Spray coating is used to produce novel nanocellulose films with controlled smoothness on steel surfaces. The smoothness of the nanocellulose film is determined by the smoothness of the receiving steel surface. Film properties like basis weight, thickness, and strength can be adjusted by changing the suspension consistency and spray coating process parameters. The surface of the film in contact with the steel surface is smoother than the air side of the film. The study investigates how suspension consistency, fiber homogenization, and addition of carboxy methyl cellulose affect the smoothness of the nanocellulose film coating. Nanocellulose fibril diameter and receiving surface roughness are found to be the key parameters that control film smoothness.

Electric vehicle and photovoltaic advanced roles in enhancing the financial p...IJECEIAES
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

31. Feasibility Analysis
The anticipated capital cost of setting up a 10 ton/day facility with a
continuous mini-fluidic type system and a case 1 based recovery system is
expected to approach ~ 14.5 million dollars. Assuming minimal silver loss
within the process, recovery of the silver ion’s activity will require
approximately ~$7000 in raw materials for every 10 tons of fish oil
processed, corresponding to the minimum recovery cost.
The cost of recovery of spent silver nitrate solution is approximately $0.70
per kg of fish oil. Raw 18/12 EE fish oil sells for approximately $2/kg.
Retail price of refined fish oils range from $20 to $30 per kg.

Conclusion
• The equilibrium concentration at 10°C has been reached in less than 36
seconds in the mini-fluidic reactor, and less than 15 min in stirred tank
reactor.
• The extract typically contained >80% omega 3, with yields above 75%.
This is beyond the capability of current molecular distillation practices
(~55%), and appears to be better than urea precipitation performance
(~65%).
• To perform the Liquid–Liquid Extraction of Omega 3 PUFA in a mini-
fluidic channel and compare the performance to an idealized system.
• To compare extraction yield in both systems.
34. Conclusion
34
• The flow patterns observed in a real fish oil / AgNO3 system was significantly
different than previously reported for a synthetic DHA/AgNO3 system.
• The addition of organic solvent into the fish oil ethyl ester increase the
interfacial tension between fish oil and silver nitrate system, However, the
increase was not sufficient to produce slug flow. This would suggest that
practical processing of fish oils with AgNO3 will require the handling of
stratified flow within the processing units.
• To investigate the hydrodynamics.
35. Conclusion
35
• A conceptual process design for silver based solvent extraction for omega 3
PUFA at an industrial scale was presented, and suggests that this process can
be feasible with appropriate silver recycling strategies.
• The approximate raw material cost of recovering and regenerating the silver-
based solvent would be ~$0.70 per kg of fish oil processed.
• To verify the feasibility at an industrial scale.
