FIELD: oil and gas industry.
SUBSTANCE: invention can be used for production of fertilisers and mixed fuels of idle natural gas. The method for carbamide production includes extraction of idle natural gas, its mixing, removal of moisture and potential destructive substances, reforming, recovery of CO2 flow from natural reformed gas, combination of the recovered CO2 flow with ammonia flow and extraction of carbamide. The system for carbamide production includes a purification module, a reforming module, a conversion module, modules for production of ammonia and carbamide, at that one of the modules is transferrable.
EFFECT: invention allows optimisation of production process, simplification of design, reduction of time for carbamide production as well as operation of the system at well locations.
