A system for recovering a sterilization agent may include a pressure reducing valve for reducing a pressure of a waste gas from a sterilization chamber to a first predefined pressure. The waste gas may include a gaseous mixture of a sterilization agent, nitrogen gas, and water vapor. A first condenser may cool the gaseous mixture to below a boiling point temperature and above a freezing point temperature of the water vapor at the first predefined pressure. A first tank may store the condensed water vapor. A separation pump may raise the pressure of the gaseous mixture to a second predefined pressure. A second condenser may cool the gaseous mixture to below a boiling point temperature and above a freezing point temperature of the sterilization agent at the second predefined pressure causing the sterilization agent to condense into a liquid. A second tank may store the separated sterilization agent.

A method to condense and liquefy vapor by introducing the vapor into a heat exchanger and bringing same into contact with a cooling body in the heat exchanger, wherein a droplet condensation promoting agent is directly added to the vapor introduced into the heat exchanger or to the heat exchanger. A droplet condensation promoting effect due to the droplet condensation promoting agent can be sufficiently manifested and condensation efficiency by droplet condensation can be improved by way of directly adding the droplet condensation promoting agent such as a film forming amine or the like to the vapor introduced into the heat exchanger or to the heat exchanger.
