Abstract
PURPOSE: To cheaply obtain a mixed gas for ammonia synthesis at a reduced power cost by purifying exhaust gas from a methanol synthesis process and introducing N2 generated by air liquefaction and fractional distillation into the resulting H2 gas.
CONSTITUTION: Part of exhaust gas contg. 79.4% H2, etc. from a methanol synthesis process consisting of reforming process 1, compression process 2 and synthesis process 3 using lower hydrocarbon such as natural gas as raw material is circulated to process 2, and the remainder is fed to CO2 removing process 4 of an ammonia synthesis process under a press. of 75kg/cm2 to remove CO2 and a little methanol by cold physical absorption. The gas passed through process 4 is washed in washing process 5 with liquid N2 from air liquefaction and fractional distillation process 6 to remove impurities such as methane and CO, and N2 is mixed into the resulting gas to obtain a mixed gas with a N2 to H2 vol. ratio of 1:3 for NH3 synthesis. The high press. of the mixed gas can reduce the power for compression. Using O2-rich gas from N2 separation process 6 for fuel of process 1, the power of a fan for feeding air to a reforming furnace is reduced.
