Managing Coke Drum Foam with Chemicals

Evan Hyde Facilitator: Evan Hyde – REFCOMM®


Managing Coke Drum Foam with Chemicals

The production of foam above the level of the coke bed during and after coke drum filling is just part of the process and is inevitable (generally). There are various scenarios where more or less foam can be expected. As part of this webinar, we will explore how foam can be reduced or managed with antifoam chemicals and through process awareness. Foam awareness starts with crude selection, progresses to antifoam injection practices, and ends in the operator’s hands with various cycle steps. Join us to explore all aspects of foam in the coke drum and how it can be mitigated or managed successfully.
