[0020] Example The present invention provides a kind of in order to solve above-mentioned technical problem, the present invention provides a kind of formamide tail gas recovery comprehensive utilization process, comprises the following steps:
[0021] 1) First, pressurize the formamide tail gas to 13Mpa through a hydrogen compressor at room temperature;
[0022] 2) Then the exhaust gas enters the gas-gas heat exchanger and is heated to 300°C;
[0023] 3) The heated tail gas enters the reformer and undergoes the following reaction: HC00CH 3 =2CO+2H 2 , decomposed into carbon monoxide and hydrogen;
[0024] 4) The gas obtained from the reaction in the previous step enters the oxygenation reformer, and the following reaction occurs: HC00CH 3 =2CO+2H 2 ;HC00CH 3 +O 2 =2CO 2 +2H 2 , further converted into carbon monoxide, carbon dioxide and hydrogen;
[0025] 5) The obtained mixed gas is then converted into carbon dioxide by a shift furnace, and the temperature of the s...
