Abstract
A method for removing mercury from water or hydrocarbon condensate is provided. The mercury-containing liquid is sprayed into a stripper having a packing therein to facilitate its contact with a stripping gas such as air or natrual gas. The stripped product is drawn from the bottom of the stripper. The stripping gas which carries the mercury from the stripper is passed over an active adsorbent to remove the mercury. The cleaned gas may be used or recycled.
Claims21
A method for removing mercury from hydrocarbon condensate comprising:
- providing a stripper having a top, a bottom, and a packing therein;
- forming said hydrocarbon condensate into a spray;
- introducing said spray into said stripper and into contact with said packing;
- flowing a gas stream through said stripper, thereby stripping mercury from said hydrocarbon condensate;
- removing said stripped hydrocarbon condensate from the bottom of said stripper;
- and
- removing said gas, including said stripped mercury, from the top of said stripper.

A method for removing mercury from mercury-containing hydrocarbon condensate, comprising:
- spraying said condensate into a stripper;
- maintaining the temperature within said stripper at at least 200.degree. F;
- flowing a stripping gas comprising natural gas within said stripper in a direction opposite to the direction said condensate travels within said stripper, said gas stripping said mercury from said condensate;
- removing said stripped condensate from said stripper;
- removing said gas including said stripped mercury from said stripper;
- and
- removing said stripped mercury from said gas.
