Determination of Dry-Ice Formation during the Depressurization of a CO2 Re-Injection System

The associated gas of an oil-producing field in off-shore Brazil is treated to remove water, hydrocarbon condensate, H2S and CO2. For environmental reasons, the CO2-rich permeate stream from the gas treatment process must be re-injected into the reservoir.

FPSO lifecycle modelling adds benefits to development offshore West Africa

In a recent FPSO development project offshore West Africa, a lifecycle modeling approach project, ending in a direct-connect Operator Training System with Aspen HYSYS Dynamics, was used for process design and control narrative validation, procedure verification, ICSS check-out, control room operator training and support for FPSO start-up operations.
