Evaluate surfactants as antifoam substitutes in amine systems
The handling capacity of gas sweetening plants using amine solutions is greatly affected by foaming problems. To mitigate foaming problems, antifoam is injected into the amine recirculating system at Oil and Natural Gas Corp.'s Uran refinery in India.
Oil and Natural Gas Corp. (ONGC) operates an oil and natural gas processing complex at Uran in Maharashtra, India. Crude oil and associated gas produced from ONGCs western offshore fields are transported to onshore facilities at the Uran plant through subsea pipelines for processing. The crude oil is further processed, and the stabilized crude is sent to refineries via pipeline and oil tanker.
The associated gas is combined with the crude stabilization offgas and the condensate fractionating unit offgas. It is passed through gas sweetening units GSU12 and GSU13, and then through LPG recovery plants LPG1 and LPG2 for the recovery of LPG and natural gas liquids (NGL). After the recovery
