Propellants and oxidizers can be produced in modular plants near your rocket launch site. Chemical Propulsion The chemistry of traditional rocket engines is best described as combustion. Over the years many chemical systems have been used, which include but are not limited to: Propellent Hydrazine Highly Refined kerosene (RP-1) Liquid Hydrogen Highly … [Read more...]
Simulating a Divided Wall Column with CHEMCAD
ChemCad Simulation of Divided Wall Column Simulating a Divided Wall Column with various column configurations can be easily achieved when developed within ChemCad. Why would one consider a divided wall column in the first place? Divided wall columns offer savings in capital costs and operating costs but more specifically, energy costs! Traditionally, if you have n … [Read more...]
Practical Examples of the HOLL-REACTOR® – Part 2
Part 2 of the Holl-Reactor® In this second installment of the Holl-Reactor®, we will discuss practical applications. Liquid-Liquid Reactions Mixing two liquid reactants is very typical. This is oftentimes done in a Continuously Stirred Tank Reactor (CSTR). Depending upon the physical properties of the two liquids, reaction times can be anywhere from minutes to … [Read more...]
Building Reaction Flowsheets Utilizing Process Intensification – Part 1
In the first of this two part of the series, we will show two continuous chemical processes that utilize process intensification for chemical reaction systems and unit operations. The original processes were typically large bulky and spread out over significant plot space and also may have had high profiles. By introducing PI to these technologies a decrease in equipment … [Read more...]
Turn Plastics into Oil with the Right Engineering Expertise.
Today, recycling is a hallmark of life. Glass, aluminum, paper and plastics are dutifully loaded into recycling bins so that they can be reused and gain new life. The truth is that recycled plastic has limited use in the commercial world and there are very few products that can make effective use of it. So why not find another use for your end-of-life plastics? … [Read more...]
