The AMSIM software is a specialized process program that simulates the removal of hydrogen sulfide (H2S), carbon dioxide (CO2), and mercaptans from natural gas and liquefied petroleum gas (LPG) streams, using amines and physical solvents. This software is backed by more than 20 years of laboratory data.
By applying a rigorous non-equilibrium stage model and the Peng-Robinson equation-of-state, the AMSIM simulator provides simple, reliable, and efficient solutions including investigation of alternative process configurations and contacting solvents. This simulator also analyzes the sensitivity of the key operating parameters and provides a diagnostic optimization of gas and LPG sweetening units. The simulator also predicts acid gas removal over a full range of inlet conditions, process configurations, solvent types, and concentrations. The software also provides hydrocarbon emission monitoring from gas sweetening units.
