NATURAL GAS DRYING PLANT Russian patent published in 1998 - IPC

FIELD: gas producing industry; adsorption drying of natural gas. SUBSTANCE: plant has absorbers, system to provided delivery and control of amount of delivered regenerated absorbent, saturated absorber discharge system including buoy chambers with level meters on each absorber, regulator, regulating valve, collector, degassing reservoir, regeneration set, delivery pumps. Saturated absorbent discharge system has discharge chamber with absorbent level regulators. Chamber is connected with absorber by two pipelines, one of which is liquid passing pipeline with overflow edge in chamber providing constant level of absorbent in absorber. Regulating valve and pressure transmitter providing pressure in collector 0.3-1.0 MPa lower than gas pressure in absorbers is installed in collector before degassing reservoir. Above-diaphragm space of level regulator in discharge unit is connected through impulse pipeline with saturated absorbent volume before overflow edge. EFFECT: enhanced reliability and reduced power consumption of plant. 3 cl, 3 dwg
