METHOD AND DEVICE FOR OBTAINING GASIFIED AIR SEPARATION PRODUCTS UNDER PRESSURE Russian patent published in 1995 - IPC

FIELD: cryogenic engineering. SUBSTANCE: regenerator of the unit for separating air serves for creating required pressure of discharging gasified product. The liquid product flows by gravity in the coil pipe of the regenerator alternatively from two accumulating tanks. The product is supplied under positive pressure of 1.0-1.2 atm which is maintained with the control valves. The product is gasified up to 3-32 atm. The device is additionally provided with two accumulating tanks mounted in the unit above the regenerator level. The facility for creating positive pressure is made up as the unit for regenerating air separation. The facility for supplying the product to the regenerator is made up as mentioned tanks and control valves mounted in the pipe line for supplying the liquid product from the tanks to the coil pipes of the regenerator. The pipe lines for supplying liquid product to the tanks are provided with check automatic valves. The pipe lines for releasing pressure from the tanks and pressurizing the tanks are provided with the valve of forced action connected with the control-actuating mechanism. EFFECT: enhanced efficiency. 3 cl, 1 dwg
