The process of methanol with hydrogen recycle using synthesis gas with high nitrogen content

摘要

(57) Abstract The stoichiometric H₂ tonnage from the synthetic gas of 90% or less methanol make being ru manner, it recycles the synthetic gas which contains CO and CO_2, diffuses the waste gas of process and it mixes with the wealth gaseous hydrogen air current of the sufficient tonnage which can as a permeation gas, the stoichiometric H₂ tonnage is 95% or more, the join stoichiometric recycling gas air current which converts CO and the CO₂ component to methanol is made, methanol is formed. With the example where this invention is desirable, the compressed air is selected from the gas turbine, the oxidizer steam which uses this for synthesis gas generation is formed. The synthetic gas which is mixed with the said wealth hydrogen circulating gas, passing the consecutive methanol converter, to change to methanol, the non transmitted part of the waste gas of methanol process returning as the fuel of the gas turbine.
