Process Design and Operational Experience

1. Atmospheric and Vacuum Units

Have developed a data base including various crude types (Athabasca, Cold Lake, Christina Lake, Leona, Marlim etc.) validated from operating data for thermodynamics, simulation topology, cracked gas make, coking potential, and optimal HVGO/LVGO configuration.
