Patent abstract
A depressurization process for a packed separation column is provided where the column system experiences a rapid and/or severe drop in pressure that could potentially damage column components. The process provides a safe de-pressurization of the column on the outlet side by decreasing the outlet pressure in controlled steps while allowing the inlet pressure of the column time to lower after each decreased step.
