  • Method for reducing foam in a primary fractionator
    Patent number: 7906012
    Abstract: The present invention includes methods for improving the operational parameters in primary fractionators which are experiencing diminished operation efficiencies due to deposits of polymerized hydrocarbon species. The invention comprises the step of adding a foam reducing amount of a foam reducing composition at the primary fractionator. A reduction in foaming is achieved whereby the operational efficiency of the process is improved based upon operation parameters including, but not limited to, liquid-gas contact ratio, product top temperature, pressure differentials, gasoline end point or combinations thereof.
