Abstract
A defoaming composition comprising an organo siloxane polymer, an aliphatic alcohol such as 2-ethylhexanol and, optionally, a liquid carrier which can be added to a coking drum in a delayed coking process to reduce foaming. In cases where the feed stock used in the delayed coking process contains greater than one half percent total sulfur, defoaming in the coking drum can be accomplished by adding an aliphatic alcohol such as 2-ethylhexanol.
