Thermophilic anaerobic digestion operates at temperatures over 50°C, offering benefits over mesophilic digestion such as increased biogas production and pathogen inactivation. These higher temperatures allow for greater degradation of organic matter and reduction in sludge volumes. Several countries have implemented thermophilic digestion at wastewater treatment plants to increase capacity, comply with biosolids regulations, and boost biogas production for energy. Operational experiences indicate improved dewaterability and stability though odors may occur if sludge is not cooled before further treatment.

Benefits of thermophilic digestion
This document summarizes the benefits of implementing a temperature phased anaerobic digestion (TPAD) process with thermophilic and mesophilic stages in series at the Christchurch Wastewater Treatment Plant. Key benefits included a 67% increase in methane production, a 19% increase in volatile solids destruction, and pathogen indicator reductions meeting biosolids standards. The thermophilic digester commissioning process faced challenges like foaming and odor but was successful due to detailed planning and mitigation measures.

The document discusses the TCR®-process developed by Fraunhofer UMSICHT as an add-on for anaerobic digestion (AD) plants to help with digestate management challenges. The TCR®-process uses pyrolysis and reforming at 350-750°C to convert digestate into high-value biochar, syngas, and oil. This allows for the reduction of substrate quantities in AD by at least 10% while increasing efficiency. It also facilitates nitrogen removal from the liquid digestate phase and production of fertilizing biochar. The process provides opportunities to potentially achieve over £100 per tonne from improved digestate treatment and valuable product generation.

The Economic Comparison Between Dry Natural Gas And Nitrogen Gas For Strippin...
Natural gas isa substantial energy source among other sources of fossil fuels. It is usually produced saturated with water vapor under production conditions. The natural gas dehydration is very paramount in the gas industry to stripthe water vapor existing in the gas production, at low-temperature conditions that may plug the system because of hydrate formation in pipelines. Totake off water vapor from natural gas flow usestriethylene glycol (TEG) in the gas dehydration process. In the glycol method, the wet gas is contactwith leanglycolinan absorber to dehydrate naturalgas and the rich glycol will be recovered and used again. This paper deals with stripping gas in the regenerator of glycol dehydration package with part of dry natural gas instead of nitrogen for stripping water vapor from triethylene glycol and studying the economic comparison between both of them by using modeling and simulation with HYSYS program. The two methods were investigated and evaluated to choose the optimal one with respect to the capital and utility costs, provided that keeping the same specifications and quantity of the glycol purity.In addition, the wet gas from the stripping process can be used to operate texsteam pumps and compressors or recycle with wet gas feed. The model has been built according to the actual process flow diagram. Finally, the results of this model could be considered as a basis on which a new heat and material balance will be developed for the plant.

IRJET- Comparison of COP of R134A with Hydrocarbons by using VCR Cycle
This document compares the coefficient of performance (COP) of R134a, an HFC refrigerant, with hydrocarbons R600a and a 50:50 blend of R290 and R600a using a vapor compression refrigeration cycle. The study finds that the hydrocarbons and their blend have lower global warming and ozone depletion potentials than R134a. Experimental results show that at full load, the hydrocarbons maintain a lower evaporator temperature than R134a. Additionally, less refrigerant is required to charge systems using the hydrocarbons compared to R134a. Therefore, the document concludes that hydrocarbons and their blends are more environmentally friendly alternatives to R134a for use in refrig

Hydrogen Production steam reforming
This document discusses hydrogen production via steam reforming with CO2 capture. It examines the possibilities of capturing CO2 from a steam reforming hydrogen plant. There are three main locations where CO2 can be captured: 1) from the raw hydrogen stream before purification, 2) from the purge gas stream after purification, and 3) from the steam reformer flue gas. Capturing from the raw hydrogen and flue gas streams can achieve overall CO2 removal rates of 60% and 90%, respectively. Amine-based capture is commonly used for the raw hydrogen and flue gas streams. A case study found the cost of capturing from the flue gas to be higher than from the raw hydrogen stream, and in both cases the

A Systemic Optimization Approach for the Design of Natural Gas Dehydration Plant
In designing dehydration units for natural gas, several critical parameters exist which can be varied to achieve a specified dew point depression. This paper studies the effects of varying number of trays in the contactor, glycol circulation rate through the contactor, temperature of the reboiler in the regenerator, amount of stripping gas used and operating pressure of the regenerator on the water content of the gas in a glycol dehydration unit. The effect of incorporating free water knock out (FWKO) tank before the absorber is also presented. An offshore platform in the Arctic region was chosen as the base case of this simulation and was modeled by using ASPEN HYSYS. Results show that the incorporation of FWKOT does not affect the TEG circulation rate required to approach equilibrium.

Treatment of domestic wastewater in an up flow anaerobic sludge
This document summarizes a study that evaluated the performance of a laboratory-scale sewage treatment system combining an upflow anaerobic sludge blanket (UASB) reactor and a moving bed biofilm reactor (MBBR). The system was operated at different hydraulic retention times (HRTs) from 5-13.3 hours. Overall, COD removal increased from 80-86% at a 5 hour HRT to 92% at a 13.3 hour HRT. Ammonia removal in the MBBR was significantly influenced by the organic loading rate, with 62% removal at 4.6 g COD/m2-day and lower removal at higher loading rates.

Microbial catalysis of syngas fermentation into biofuels precursors - An expe...
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.

Microbial catalysis of syngas fermentation into biofuels precursors - An expe...
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.

Italcanditi-Vitalfood, a large European producer of food products, needed to expand its wastewater treatment to handle increased production volumes. It chose Fluence Corporation to install a new biological treatment system using anaerobic digestion. The system uses an external forced circulation reactor to break down organic matter in the wastewater into biogas, which is then converted to electricity and thermal energy to power the plant. This saves Italcanditi-Vitalfood around $400,000 per year compared to its previous treatment system. The combined aerobic and anaerobic biological treatment effectively handles the food industry wastewater streams while generating renewable energy.

Biomasa 2
This study aims to characterize palm oil mill effluent (POME) as a source of biogas production and to examine the biotic and abiotic factors for enhancing the POME biogas production. The results show that the POME sludge (LCPMKS) generated from PT Swastisiddhi Amarga Bioenergi mill is viscous, brown or greyish in color with total solid (TS) content of 38.5-57.4, chemical oxygen demand (COD) of 56.5-75.6, biological oxygen demand (BOD) of 35.5-40.7 and suspended solid (SS) of 28.1-46.9 in g/L. These values are above the standard threshold limits, thus POME is a potential source of environmental contamination if released untreated. Abiotic factors such as addition of Ca(OH)2 to neutralize the pH, provision of agitation system and increase in temperature enhanced the biogas production up to 50.5 L, 50.5 L and 98.5 L respectively. While, among the biotic factors, the condition which produced the highest biogas (250 L) contains the substrate volume of 50 L with 25% inoculum of type mud LCPMKS pool II using a laboratory scale anaerobic digester.

Presentation on a novel accelerated composting process.
This document summarizes a presentation on integrating hydrothermal carbonization (HTC) with anaerobic digestion (AD) to treat and valorize digestate. The goals are to understand how digestate composition and HTC process variables affect product yields and composition, and identify opportunities for integration. Laboratory experiments examined the effects of temperature, solid loading, and feedstock on HTC of different digestates. Results show digestate produces low quality "bio-coal" due to high ash, but HTC process water has biogas production potential. Integration of HTC with AD could pretreat digestate for enhanced biogas, increase digestate value, and create new solid product markets while reducing waste.
CRI - TCBiomass2011
The document discusses CRI's use of high-throughput tools to rapidly optimize catalysts and processes for biofuel production. It provides examples of successfully developing improved catalysts for ethylene oxide production and dehydrogenation reactions within 5-18 months versus 12-18 months using conventional methods. For biofuel applications, CRI screened over 150 conditions using 0.1-0.4mL of catalyst to develop a process to convert mixed alcohols to gasoline using solid acid catalysts within 3 months. This helped their partner arrive at a process design and economics more quickly. CRI's high-throughput approach can help deploy application-specific biofuel catalysts and processes faster.

- Catalytic hydrotreating was effectively used to upgrade the biocrude through hydrodeoxygenation, hydrodenitrogenation, and hydrodesulfurization, producing hydrocarbon fuels.
- Catalytic hydrothermal gasification of the aqueous byproduct stream effectively produced fuel gas and allowed for
Does Heavy Oil Recovery Need Steam?
Heavy Oil recovery traditionally starts with depletion drive and (natural) waterdrive with very low recoveries as a result. As EOR technique, steam injection has been matured since the 1950s using CSS (cyclic steam stimulation), steam drive or steam flooding, and SAGD (steam assisted gravity drainage). The high energy cost of heating up the oil bearing formation to steam temperature and the associated high CO2 footprint make steam based technology less attractive today and many companies in the industry have been actively trying to find alternatives or improvements. As a result there are now many more energy efficient recovery technologies that can unlock heavy oil resources compared with only a decade ago. This presentation will discuss breakthrough alternatives to steam based recovery as well as incremental improvement options to steam injection techniques. The key message is the importance to consider these techniques because steam injection is costly and has a high CO2 footprint

It provides "dos and don'ts" of AD system design and examples of typical digester feedstocks and projects.
Hydrogen production in refinery
The document discusses hydrogen production via steam reforming of natural gas. Steam reforming involves four steps: reforming, shift conversion, gas purification, and methanation. It produces hydrogen at high efficiency and is the lowest cost production method currently available. However, it also produces carbon dioxide as a byproduct. Newer steam reforming plants use pressure swing absorption to produce 99.99% pure hydrogen. While steam reforming is an efficient process, it contributes to carbon dioxide emissions, so methods to capture and store the CO2 are being investigated.

BTG is an independent firm specialized in biomass conversion technologies with 25 years of experience developing and implementing bioenergy systems in over 80 countries. Fast pyrolysis is a process that converts biomass into bio-oil by rapidly heating biomass to 450-600°C in the absence of air, producing 75% liquid bio-oil, 12% char, and 13% gas. Fast pyrolysis has advantages over other conversion methods as the liquid bio-oil is easier to transport and produces fewer emissions than combustion. BTG has developed and operated modular 2 ton/hr fast pyrolysis plants to produce bio-oil from various biomass feedstocks.
Anaerobic-Aerobic Treatment of Sewage
The document proposes an anaerobic-aerobic process for treating domestic sewage using LEVAPOR biofilm technology. The process involves pre-treating sewage under anaerobic conditions in a biofilm reactor to reduce energy use and excess sludge production compared to conventional aerobic treatment. Sewage would then undergo post-treatment under aerobic conditions to further reduce pollutants before discharge. This process could achieve up to 75% lower energy use and 67% less sludge than aerobic treatment alone, while also producing biogas as an energy source.

This document discusses Dairygold's anaerobic digestion project to reduce fossil fuel dependency and increase waste treatment capacity. The project involved constructing a 45,000 m3 anaerobic digester, the largest in the dairy industry, to treat 27,000 kg/day of organic waste from milk processing into biogas. The €8 million investment generates over 9.1 million kWh of thermal energy annually, providing 6% of the site's steam needs and reducing carbon dioxide emissions by over 1,900 tons per year compared to conventional aerobic treatment. The anaerobic digestion process is more energy efficient and produces less sludge than alternative technologies.
third_series_by_dr-_salim-1.pdf
Biomass is a renewable energy resource that can be converted into bioenergy through various thermochemical and biochemical processes. Thermochemical processes like pyrolysis and gasification involve heating biomass to produce syngas, bio-oil, and char. Gasification occurs with limited oxygen and produces a combustible gas mixture. Biochemical processes include anaerobic digestion and fermentation. Anaerobic digestion breaks down biomass without oxygen to produce biogas and digestate. Fermentation converts biomass into biofuels like bioethanol. Both thermochemical and biochemical conversion technologies are being improved to promote bioenergy development by upgrading fuel quality and enhancing reaction mechanisms.

Dandelion Hashtable: beyond billion requests per second on a commodity server
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.
