Filed: 1996-10-04
Granted: 1999-11-20
Abstract: FIELD: gas production method. SUBSTANCE: according to method, liquefaction of natural gas is performed by passing natural gas through series of successively installed heat exchangers in counterflow with respect to gaseous cooling agent circulating in cycle of working expansion. Working expansion cycle includes compression of cooling agent, separation and cooling of agent for creation of at least first and second flows of cooled agent. Then follows is isoentropic expansion of first flow of cooling agent to maximal low temperature, and isoentropic expansion of second flow of cooling agent to intermediate temperature of cooling agent. Performed is delivery of cooling agent in first and second flow into corresponding heat exchanger for cooling of natural gas down to respective ranges of temperature. Cooling agent of first flow is expanded isoentropically to pressure which is at least 10 times higher than total pressure drop of cooling agent in first flow of cooling agent in succession of heat exchangers, and this pressure stays within range of 1.2-2.5 MPa. Application of aforesaid method allows for performing liquefaction of natural gas directly at recovering gas at sea. EFFECT: higher efficiency. 17 cl, 13 dwg

Abstract: FIELD: polygraphic engineering. SUBSTANCE: apparatus has base, piston-type pneumatic drive, carriage connected with pneumatic drive piston through flexible connecting member, which is attached with its one end to piston upper part and with its other end to carriage. Electric drive is fixed on pole. Carriage is kinematically connected with electric drive through V-belt transmission. Sheet separating disk has window with separating teeth, grooves and working bores, each terminating with its one end in related groove and with its other end in end of sheet separating disk, and registry bores. Each pair of registry bores is connected via registry opening and is open toward end of disk. Planar distributor provided with working and registry grooves is fixed on carriage. Registry groove is coupled to sensor, which is connected with counter. Vacuumizer is connected with valves, one of valves is connected with chamber below piston. Upon switching, valve comes into communication with atmosphere and atmospheric air is admitted into chamber. As a result, pressure difference acting upon piston is decreased and carriage begins to lower under gravity till disk comes into contact with angle of paper sheet stack. When rotating disk comes into contact with top sheet of stack, groove deforms angle of paper sheet in accordance with groove shape, and separating tooth is inserted into slit formed upon deformation of paper sheet and transfers angle of paper sheet onto upper surface of separating tooth. This paper sheet overlaps registry opening. Vacuum created in registry groove activates sensor and counter registers counted paper sheet. Upon further rotation of disk, registry opening is again communicated with atmosphere and subsequent groove deforms subsequent paper sheet and subsequent separating tooth transfers angle of sheet onto its surface to overlap its registry opening. EFFECT: reduced sizes of apparatus and enhanced reliability in operation. 6 cl, 5 dwg
