In a process for collecting the hot blow gases from a steel converter, in which a shielding gas is directed at the joint between the top of the converter and a collection conduit, the shielding gas is CO 2 or steam. The hot gases pass from the conduit to heat exchangers (which raise steam), carbon monoxide shift reactor and CO 2 - removal plant, and the steam or CO 2 for the shielding gas may be supplied from these sources. Thus control of the quantities of shielding gas used enables the product gas to be used for making H 2 , CO, or a methanol synthesis gas.
