METHOD OF PRODUCING SYNGAS AND A DEVICE FOR COOLING SYNGAS Russian patent published in 2020 - IPC C01B3/36 C01B3/38 

FIELD: chemistry; manufacturing technology.

SUBSTANCE: invention relates to a method of producing syngas containing hydrogen and carbon monoxide from preheated methane-containing gas and to a cooling device for cooling hot crude gas. Method comprises the following steps: (a) carrying out a reaction between preheated methane-containing gas and an oxidant gas to obtain hot crude syngas, containing carbon monoxide and hydrogen; (b) cooling hot crude syngas obtained at step (a) to obtain syngas by indirect heat exchange with water to obtain saturated steam; (c) additional cooling of crude syngas obtained at step (b) by indirect heat exchange with methane-containing gas to obtain cooled crude gas-phase syngas and preheated methane-containing gas for use in step (a), wherein (i) steps (b) and (c) pass in a single cooling device for combined indirect heat exchange with water and a methane-containing gas; and (ii) preheated methane-containing gas obtained at step (c) has temperature of 400 to 650 °C.

EFFECT: technical result consists in providing a method in which heat contained in hot crude syngas can be more efficiently regenerated.
