How sensitive is your treating plant to operating conditions?

Weiland, R., Optimized Gas Treating, Inc.; Schultes, M., Raschig GmbH; Maharaj, N., Atlantic LNG Company of Trinidad and Tobago; Praderio, A., ConocoPhillips; Santos, J., INEOS Americas

A normal expectation in the course of operating an amine treating plant for acid gas removal is that small changes in operating conditions will result in correspondingly small responses in plant performance. However, such expectations are not always well founded. To establish credibility for the process simulator used in the design of a new LNG plant, the mass-transfer rate-based simulation results for the new plant are compared with performance data from an operating LNG plant.
