Heat management process

A process comprising.

• a) providing a vapor phase vent stream from a chemical process that employs organics and H2, the stream comprising an uncondensed product, organics, hydrogen and inert gases,
• b) cooling the vent stream in a cross-exchanger to form a cooled stream,
• c) separating the cooled stream into a crude product liquid stream and a gas phase stream,
• d) lowering, in a depressurization device, the pressure of the gas phase stream to form a cooled gas phase stream, wherein the pressure drop across the depressurization device is greater than 1 bar and the organics to H2 weight ratio of the cooled gas phase stream is greater than 8:1, and
• e) using the cooled gas phase stream in the cross exchanger to cool the vapor phase vent stream.
