OR-9 CO 2 Absorption Studies Expected Benefit toMembers: Acid gas absorption is a huge and growing area. The economic benefits of any technical advances could be very large. Present Situation and Proposed Research: Dr. Ralph Weiland, of Optimized Gas Treating, was consulted. Dr. Weiland suggested three ideas for research as follows: 1. Testing of new solvents such as potassium dimethyl glycinate promoted with piperazine 2. Amine regeneration, which has received far less attention than amine absorption 3. Heat transfer between phases during the quenching operation that will have to be done on flue gas before it passes to the absorption system Dr. Weiland would be willing to consult occasionally on any such project. FRI could collaborate with SRP, OSU or an industrial partner on such work. It is also probable that federal funding could be obtained, if FRI was willing to accept the associated paperwork difficulties. Proposed Internals and Test System: Tray and packing performances could be compared. High-cost internals would not be required. Estimated Unit Time: It might take 6 months and appreciable capital to convert the Stillwater Unit for absorption research. Estimated Additional Costs (Beyond Unit Time): As a guesstimate, $150K would be required to convert the Stillwater Unit for absorption research. Background and Discussion: Many years ago, the Alhambra Unit was utilized, with difficulty, for absorption research. It is possible that OSU and ConocoPhillips will soon be embarking on a joint CO2 project. It is believed that SRP is already working on regeneration research. The conversion of the Stillwater Unit for absorption research is not recommended by the Technical Director (MRR) who feels that such a conversion would stop necessary distillation development for many years – if not forever.
