Is your antifoam compatible with the amine system?
Several options help minimize operation costs and mitigate unscheduled shutdowns
The specific behavior of antifoam use was studied in a particular plant. The goal was to find a solution for applying the new antifoam for the best compatibility with amine systems. A gas sweetening unit was installed to remove hydrogen sulfide (H2S) contained in a high-pressure (HP) natural gas stream. The solvent used for the H2S removal from the gaseous stream was a 34 wt% diethanolamine (DEA) solution, and the designed plant treating capacity was 250 million standard cubic feet per day (MMscfd) of HP sour gas. Due to bad filtration and an improper antifoam selection, an upset occurred that created foaming at the contactor tower. Six months after the unit startup, the deferential pressure
