A waste gas recovery system employs a compressor which takes in waste gas from an inlet knock-out drum and passes compressed gas to a heat exchanger which cools the gas prior to passage through a further outlet knockout drum. The compressor is driven at a speed which is selected in accordance with the sensed pressure of the incoming waste gas and a valve progressively controls the supply of gas to the compressor inlet in accordance with the sensed pressure. Liquid condensate from the knock-out drums collects in a header tank. A temperature sensing and control arrangement injects liquid from this tank at the inlet to the compressor in the event of an excessive temperature rise at the outlet of the compressor. Gas is also re-circulated from the output of the system to the compressor inlet should the injection of liquid be insufficient to reduce the temperature rise. In the event that the pressure of the waste gas fed to the inlet of the compressor falls below a set minimum value, the control arrangement ensures that the compressor runs with gas recirculating continuously between the output of the system and the compressor inlet.
