  • Method for quick turnaround of hydrocarbon processing units
    Patent number: 5425814
    Abstract: A quick cleaning method for hydrocarbon processing is described which avoids using the time honored steamout as a cleaning step by isolating the equipment to be cleaned from the rest of the hydrocarbon processing units, establishing a circulation loop and by pumping through the equipment an aqueous solution at an elevated temperature, of an extractant, such as a terpene, and a surfactant mixture which extracts and traps contaminants in an emulsion which is normally subjected to a high shearing step before recirculation to the equipment.
