| titleOfInvention | A kind of low pressure ammonia synthesis technology of combined production of methanol |
| abstract | The present invention provides a kind of low pressure ammonia synthesis technology of combined production of methanol, include the following steps: 1) to carry out cryogenic air separation unit to air, obtain nitrogen and oxygen, oxygen and natural gas carry out pure oxygen autothermal reforming, obtain containing CO and H 2 Gaseous mixture；2) CO and H will be contained 2 Gaseous mixture be divided into two strands, synthesizing methanol, another burst of progress electrolysis water separation obtain hydrogen under the effect of the catalyst for one；3) hydrogen and nitrogen are mixed into syngas for synthetic ammonia, and it is subjected to level-one ammonia synthesis, synthesis pressure 5-7MPa in the first ammonia convertor of filling ferrum-based catalyst；4) second level ammonia synthesis, synthesis pressure 4-6MPa are carried out from the second ammonia convertor that the gaseous mixture come out in first ammonia convertor enters filling ruthenium-based catalyst.Present invention accomplishes ammonia synthesis process to require, guarantees technique even running, also improves the utilization rate of ammonia convertor outlet ammonia net value and nitrogen and hydrogen, coproduction methanol. |
