Carbon Dioxide (CO2) is known as one of industrial waste gas causing global warming...there are number of measures are implemented to reduce global warming. CO2 reduction measures are CO2 capturing, reinjection into aquifer, injection into reservior for well maintenance, gas injection for enhanced oil recovery (EOR), etc.
Above efforts will reduce CO2 release into atmosphere. However, recycling CO2 will increase quantity of CO2 in oil and result serious corrosion problem. Hence it needs to be removed from the flashed gas (from unstabilised oil). CO2 removal technology using amine absorption has been used for many years. Recently i found a website (OGT) where the founders, Ralph Weiland and Jack Dingman are those experts in this technology.
Optimized Gas Treating, Inc. (OGT) was established in 1992 by Ralph Weiland and Jack Dingman for the single purpose of providing a commercial version of a Windows-based software package for simulating acid gas removal with aqueous alkanolamines that uses a fundamental mass and heat transfer rate approach to column modeling. ProTreat™ is the culmination of more than 30 years of research in gas treating supported by government and industry in both academic and commercial environments. ProTreat is our sole product. Consequently, it receives our undivided attention in maintaining and enhancing its capabilities so that it remains the premier software package for gas treating with amines. OGT’s principals are recognized world experts in most aspects of gas treating — they offer a total of nearly 60 years of relevant experience.

ChemSep-LITE is available for FREE download and is now CAPE-OPEN compliant (article in NPT). It can be used as a stand-alone column simulator or as a unit operation model inside any CO compliant flowsheet simulation program such as ASPEN Plus or COCO. ChemSep-LITE includes the equilibrium column model and is limited to 5 components and 50 stages.
