Integrated Knockout Drum and Heat Exchanger for Use in Cleaning Process

A method for handling effluent produced in a cleaning process of refinery equipment, the method comprising:

• receiving the effluent at an inlet of a drum;
• condensing an amount of the effluent by passing the effluent from the inlet along a heat exchanger disposed in a shell housed inside the drum;
• releasing the condensed amount and any uncondensed amount of the effluent from the shell into an interior of the drum;
• communicating the condensed amount out of the interior from a first outlet of the drum;
• and
• communicating the uncondensed amount out the interior from a second outlet of the drum.
