The CATACARB® Process, the state-of-the-art in Hot Potassium Carbonate, was invented and developed by A.G. Eickmeyer. As an employee of Stanolind Oil & Gas Co. and J.F. Pritchard & Co. in the 1940’s and 50’s, he became familiar with the Hot Potassium Carbonate (HPC) process being developed by the U.S. Bureau of Mines.
Eickmeyer believed the HPC process had many advantages, but through his trouble-shooting work on most of the early HPC installations, he also became aware of some drawbacks. The process required substantially less heat than the Amine processes, but absorption/desorption rates were slow. In addition, the equipment was too large, and the solution was sometimes corrosive.
Eickmeyer studied and recorrelated the Bureau of Mines’ data and arrived at significantly different operating conditions which allowed these plants to achieve as much as 110% of design production.
Through the development of various catalysts and corrosion inhibitors, E&A has been able to improve on the original HPC process. The catalysts greatly increase the rate of absorption and desorption of acid gases, thereby reducing equipment sizes, capital costs, utility requirements, and residual CO2 and H2S contents. In addition, through the use of corrosion inhibitors, costs have been reduced even further by minimizing the need for extensive use of stainless steel.
The result of all of this work is the CATACARB® process, the state-of-the-art in Hot Potassium Carbonate.
Many process and mechanical configurations are available for the CATACARB® Process, making it adaptable to a wide range of applications. However, the most common applications include ammonia, hydrogen, natural gas, and ethylene oxide (EO) plants.
