How sensitive is your treating plant to operating conditions?

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.

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.

Attention is then turned to another LNG project under study. The project’s carbon dioxide (CO2) removal system consists of a single, large absorber serviced by two regenerators in parallel. Initially, the plant would process about 1,400 million cubic feet per day (MMcfd) of gas containing approximately 16 mol% of CO2. A sensitivity analysis shows potential susceptibility of treating performance to departures of certain operating conditions from design values, and it also provides reasons for this sensitivity.
