Search HOME OUR COMPANY OUR EXPERIENCE PRODUCTS SERVICES CONTACT US Our Experience Unrivaled Experience in the Hot Potassium Carbonate Process: At Eickmeyer & Associates, Inc., we have over 50 years experience with the Hot Potassium Carbonate Process for acid gas removal. We have designed over 150 CATACARB® plants in over 30 countries in applications including, but not limited to, ammonia, ethylene oxide, hydrogen, NG/SNG, and VAM. CATACARB® units operate around the clock – around the world – removing acid gas in chemical, refinery, and fertilizer complexes. The inherent low energy requirements of the Hot Potassium Carbonate Process combined with the improved efficiency resulting from use of CATACARB® catalysts and inhibitors offers the best energy conservation and highest performance available. The experience of our specialists complete the successful formula. Experience in Ammonia and Hydrogen Plants: Eickmeyer & Associates, Inc. has been designing and successfully implementing CATACARB® enhanced HPC systems for ammonia and hydrogen plant applications since the early 1960s. In fact, many of the early implementations of CATACARB® are still operational and serviced by Eickmeyer & Associates, Inc. to this day. The CATACARB® Process requires low capital investment and has a relatively high heat efficiency as compared with Amine scrubbing systems. Purified gas under adequate pressure can contain less than 2000 ppm of CO2. Furthermore, the CATACARB® Process produces a high purity CO2 stream that, in the absence of sulfur, is suitable for making urea, liquid CO2, or dry ice for beverage use and enhanced oil recovery. Experience in Ethylene Oxide (EO) Recycle Gas: The CATACARB® Process has been proven extensively for removing CO2 from ethylene oxide recycle gas. Many of the leading EO/EG producers and licensors, such as SHELL Chemicals, BASF, SHARQ, and Mitsubishi, employ the CATACARB® process for their CO2 removal needs. CO2 is produced as a byproduct from the ethylene oxide reactor. The removal of this CO2 causes some difficulty. The O2 in the feed gas will cause many solvents to degrade. In addition, there is the possibility of reaction between many solvents and the EO present in the feed gas. However, with our inorganic catalyst, the CATACARB® Process is completely resistant to O2 and EO. Using the CATACARB® Process, the CO2 is typically treated to levels between 1.2% and 0.8% before the EO gas is sent for recovery. However, the CO2 can be treated to levels as low as 2000 ppm. Typical heat efficiencies in EO application are between 50-65 MMBTU/LB-MOl CO2. This represents a 20-30% improvement in energy efficiency when compared with unactivated HPC systems. Experience in Other Areas: In addition to ammonia, hydrogen, and ethylene oxide applications, the CATACARB® Process has been implemented in NG/SNG, VAM, methanol synthesis gas, autoclave recycle O2 stream, and N2O product stream applications.
