METHOD OF JOINT PRODUCTION OF AMMONIA AND METHANOL Russian patent published in 2018 - IPC C07C31/04 C01C1/04 C01B3/38 

FIELD: chemistry.

SUBSTANCE: invention relates to the field of the chemical industry, namely to the joint production of ammonia and methanol from hydrocarbon feedstocks. Method includes reforming natural gas, utilizing reforming heat, converting carbon monoxide, purifying converted gas from carbon dioxide, synthesizing methanol, methanizing and synthesizing ammonia. Hot converted synthesis gas from the primary or secondary reforming is fed to the shell space of the post-reformer, which is a shell-and-tube heat exchange reactor, and in the pipes filled with the catalyst, an additional raw gas-vapor mixture, which is supplied from a common mixing tee or from separate mixing tees. Further, the synthesis gas stream from the intertubular space for ammonia production is fed to CO conversion either directly, if post-reforming is installed after the secondary reforming shaft furnace, or through secondary reforming, if post-reforming is installed after the primary reforming tube furnace.

EFFECT: increase in the productivity of the method of joint production of ammonia and methanol, optimization of the composition of synthesis gas, reduction of the carbon monoxide content in front of the methanator and in the reduction of harmful substances.
