The Nelson-Farrar Cost Indexes The Nelson-Farrar Cost Indexes were started by Dr. W. L. Nelson and Dr. Gerald L. Farrar. The indexes were calculated and published in every issue each month by the Oil & Gas Journal and with quarterly summaries in the January, April, July, and October issues. The indexes were originally named the Nelson Cost … [Read more...]
Converting Oceanbound Plastics to Hydrocarbon Fuels
Oceanbound Plastics a Global Problem Conventional wisdom suggests that the answer to addressing this Oceanbound plastics global problem is heading out to sea with equipment capable of scooping plastic out of the marine environment and processing it into something of value. A romantic notion no doubt, however, the physics of the marine and tidal environment coupled with the … [Read more...]
The Chemistry and Physics of Rocket Engines
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...]
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...]
