Title: Method and system for removing hydrocarbon deposits from heat exchanger tube bundles
Inventor: TOMKINS MICHAEL
IPC: F28G9/00
Filed: 2012-12-07
Granted: 2021-03-09
Abstract: A method and system for removing hydrocarbon deposits from a heat exchanger tube bundle using an organic solvent working fluid working fluid. After contact with a heat exchanger tube bundle, the hydrocarbon-laden organic solvent working fluid may be treated to remove solids, base waters, and/or suspended hydrocarbons, and then again contacted with a heat exchanger tube bundle for the removal of hydrocarbon deposits. This allows for the removal of hydrocarbon deposits from a heat exchanger tube bundle in an efficient and environmentally friendly manner. The organic solvent working fluid is recycled after proper treatment to be used repeatedly. The only loss and thus makeup required is a small fraction that ends up in the recovered hydrocarbons that is sent back into the refinery or other facility.
