Abstract

1,268,069. Gas liquefaction apparatus. STRUTHERS SCIENTIFIC & INTERNATIONAL CORP. 4 Aug., 1970 [6 Aug., 1969], No. 39401/69. Heading F4P. Liquefaction of a small proportion e.g., 1% of a compressed gas stream e.g., natural gas at 150 p.s.i. and 530‹ R. i.e., 70‹ F. is effected by passing the feed stream at 1 into the warm end of the high pressure side 3 of an indirect heat exchanger 2, withdrawing through lines 6 to 10 portions of compressed feed and expanding them in Ranque-Hilsch vortex tubes 12 to 15, passing cold. low pressure gas at temperatures 407‹ R., 340‹ R., 285‹ R., 240‹ R. and 202‹ R. through lines 21 to 25 respectively extending from said tubes 12 to 15 to spaced points along a low pressure side 4 of the exchanger 2 thereby icooling the residual high pressure feed gas which is withdrawn at 204‹ R. through a line 27 and expanded with liquefaction into a flask tank 30 Relatively warm expanded gas is discharged by tubes 11 to 15 through lines 16 to 20 at temperatures of 610‹ R., 510‹ R., 427‹ R., 360‹ R. and 302‹ R. respectively and which lines also lead to the low pressure side 4 of the exchanger 2.
