UNIT FOR PRODUCING OF FUEL GAS FOR PROCESS FURNACES Russian patent published in 2015 - IPC C10L3/10 B01D53/52 

FIELD: metallurgy.

SUBSTANCE: invention describes the unit for producing of fuel gas from low-potential hydrocarbon gases of oil and gas processing and stripping HBG of process of a reforming which includes an absorbing column for purification of hydrocarbon gases, with the inlet line of supply of water solution of monoethanol amine (MEA) fitted with the pump and the heat exchanger for cooling of MEA water solution, a separator for drying of the cleaned hydrocarbon gases, two parallel gas-jet ejectors with inlet lines of supply of cleaned and drained hydrocarbon gases and HBG, a separator for drying and a heat exchanger for heating of produced fuel gas. This unit combines the stages of cleaning and mixing of gas flows allows with the minimum power consumption using the principle of direct supply to involve into process the low-potential hydrocarbon gases and stripping hydrogenous gas which earlier were to be burned in flare units i.e. provides the possibility of full processing of flue production gases, allowing to produce fuel gas with heat of combustion at the level of natural gas, effectively to use raw material resources and to raise oil refining depth level.

EFFECT: process is performed using the simple manufacturable equipment.
