Additionally, the purge stream contains CO and CH4, which will bring in considerable greenhouse emissions if the direct emissions apply. With the assistance of air, a burner is used to deal with these C1 components. An RGibbs reactor @ 600 ℃ is used to simulate the burner. Due to the exothermic reactions, the burner will release heat, while the waste heat recovery technology can be used to recover the part of burner heating (utilization efficiency is assumed at Z +56786 = 60%) to reduce the heating utility of steam or fuel gas.
