METHOD AND SYSTEM FOR OBTAINING PETROL OR DIMETHYL ETHER Russian patent published in 2016 - IPC C10G3/00 C10G2/00 C07C1/02 C07C41/09 C07C43/04 

FIELD: chemistry.

SUBSTANCE: system for obtaining petrol or dimethyl ether from natural gas with intermediate methanol synthesis includes: device (10) for steam natural gas reforming for obtaining reforming gas; heat exchanger (17) of flue gas-steam type for obtaining steam or heat, used in system, by recovery of heat of flue gas, formed in combustion zone (12) of steam reforming device (10); methanol synthesis device (20) from reforming gas, obtained in device for steam reforming; heat exchanger (19) of reforming gas-steam type, intended for obtaining steam or heat, used in system, by recovery of reforming gas heat before supply of reforming gas into methanol synthesis device (20); device (30) for synthesis of petrol or dimethyl ether from methanol, synthesised in methanol synthesis device, and device, selected from the group, and a series of heat exchanges as shown in the invention formula. Signs, effecting total energy balance of system, are formulated for system.

EFFECT: effective application of heat, obtained in method or system.
