About Us


Optimized Gas Treating, Inc. (OGT) was established in 1992 by Ralph Weiland and Jack Dingman to provide a commercial version of a Windows-based software package for simulating acid gas removal specifically with aqueous alkanolamines. ProTreat software is distinguished by its exclusive use of a fundamental mass and heat transfer rate approach to column modeling and now includes a number of proprietary solvents, physical and hybrid solvents, dehydration, sour water stripping, and most recently a full sulphur plant simulator and a COM interface making ProTreat essentially Cape open. 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 and sulphur recovery. OGT’s staff are recognized world experts in all aspects of gas treating, offering a total of over 150 man-years of relevant experience.
