Koch Modular Process Systems presented on extractive distillation. Extractive distillation involves adding a high-boiling solvent to a binary mixture to alter the relative volatility of the components and allow separation via distillation. It can be considered for mixtures that form azeotropes or have low relative volatility. Examples were given of mixtures like acetone/methanol and THF/water that can be separated through extractive distillation using appropriate solvents. Attendees were encouraged to evaluate extractive distillation for difficult separation challenges.
Enhanced Ammonia Recovery with Built-In Feed Flexibility
Ammonia absorption and recovery projects are not a
unique challenge for the Koch Modular process team. They
have a high level of experience in this area and with an
abundance of existing data, no pilot trials were necessary
to design a solution and then guarantee the ammonia
absorption system performance. However, there were
challenges. The ammonia vapor feed stream was composed
of multiple ammonia-containing streams with a variety of
compositions. The Koch Modular team worked with the
client to agree upon a feed basis for the design of the
system. As often occurs, the ammonia recovery project
was part of an overall major expansion, and the client
requested that the modules be designed to fit indoors both
functionally and spatially into the new facility. This request,
and the overall scale and building configuration presented
some unique design challenges.
Bio-Based Plastic - A Novel Process Solutions Approach for Successful, Lower Cost Scale-Up.
Koch Modular was initially approached for their demonstrated
optimization expertise in reaction, distillation and filtration unit
operations. One of the technical challenges the company faced
was determining how to compensate for changing byproduct
compositions as a result of evolving feedstock selection,
alongside the need to produce a consistent yield of material.
They also requested guidance with engineering services,
process conceptualization and pilot testing in order to take
their revolutionary, small-scale manufacturing to successful
full-scale production.
Product purification and recovery remains a priority for chemical engineers, today. Designing separations processes to accomplish the above is a challenge, especially as streams get more complex in composition. Though often overlooked, liquid-liquid extraction (LLE) is a powerful separation technique for both organic and aqueous liquids. Whereas distillation technology relies on relative volatility differences among chemicals, LLE exploits the differences in relative solubilities of compounds in two immiscible liquids, to perform the key separation. Distillation may not be feasible when boiling points are nearly identical or for other reasons, economic and technical. When distillation is not a viable solution, LLE is a great alternative to achieve product purification and recovery.

According to the Construction Industry Institute, modularization entails the large-scale transfer of stick-build construction effort from the jobsite to one or more local or distant fabrication shops/yards in order to exploit one or more strategic advantages. Nonetheless, the majority of projects today still do not exploit these strategic advantages to their fullest potential.
Modular Construction has many advantages over conventional stick-build construction. These benefits include shorter schedules, lower cost overall cost, minimal plant site interruption and many more. Strengthen your knowledge of when and why to choose modularization as a project delivery model.

This document discusses a modular construction project called "Chill" that was completed successfully to address scheduling concerns for a larger project. The Chemours company was initially concerned about working with a modular contractor for various reasons relating to space, access, and construction. However, Koch Modular Process Systems was able to address all of Chemours' concerns through their modular design. This included removing temporary steel supports after installation, minimizing interior bracing, and ensuring proper access, egress, and safety features. As a result, the modular facility was delivered ahead of schedule and under budget compared to traditional construction. Chemours was so satisfied that they hired Koch Modular for two additional projects.
A specialty chemical company hired Koch Modular to design and build a modular distillation system to recover spent solvents. Koch Modular engineered a multi-step distillation process using modular units that provided lower energy usage than the existing system. The modular design allowed for expedited fabrication and installation with minimal disruption to plant operations. The new system increased production capacity by 40% to meet growing market demand.
This document discusses various methods for breaking azeotropes in distillation operations. An azeotrope is a mixture that boils as a single composition in liquid and vapor phases, making separation via simple distillation impossible. The easiest type to break is a heterogeneous azeotrope, using a combination of distillation and decantation into separate phases. Pressure swing distillation and azeotropic distillation using an additional entrainer component are effective for homogeneous azeotropes. Other techniques include extractive distillation, liquid-liquid extraction, and newer membrane technologies. Determining the best approach requires substantial experience, as pilot testing is usually needed to account for real feedstock variations not seen in
Equilibrium data and related information gathered from a liquid-liquid extraction laboratory “shake test” can provide information for process feasibility and column-type selection in the scaleup of liquid-liquid extraction processes
Most chemical engineers have had the experience of dealing with problematic separations, and most have a general understanding of distillation processes. When it comes to liquid-liquid extraction (LLE) processes (Figure 1), however, the details of how these processes work are often less clear. Most academic chemical engineering degree programs do not heavily emphasize liquid-liquid extraction, and most chemical engineering graduates did not receive more than a few days of instruction on generating equilibrium data for LLE in their degree programs.

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
