METHOD AND APPARATUS FOR COOLING A FLOW CONTAINING AT LEAST 35% CARBON DIOXIDE AND MERCURY

摘要

In a method for cooling a flow containing at least 35% carbon dioxide and at least 0.2 μg/Nm3 of mercury, the mercury being in liquid and/or gas form, the flow is cooled in a first brazed aluminum plate-fin heat exchanger from a first temperature to a second temperature higher than −38.6° C. to form a cold flow at the second temperature, and the flow cooled to the second temperature is cooled in a second heat exchanger, which is a tube and shell heat exchanger, to a third temperature lower than −38.6° C.
