As shown in Fig. 5, a threestage displacer 20, 22, 62 is movable in a stepped housing 70 surrounded by a correspondingly stepped housing 12, 14, 63, regenerators 25, 28, 65 and heat exchangers 27, 30, 67 being provided in the three annular spaces defined by the inner and outer housings. Coils 31, 32, 68 for fluid to be cooled are bonded to the outer housing adjacent heat exchangers 27, 30, 67. Gas is supplied to and withdrawn from the machine via a conduit 51 which as shown in Fig. 11 communicates with a circuit comprising a low-pressure receiver 52, compressor 56, cooler 67, high-pressure receiver 48 and valves 50 and 54. In operation, with the displacers in their lowest position valve 54 is closed and valve 50 is opened so that high pressure gas is supplied to the machine. The displacers then move upwardly to force the gas through the regenerators and heat exchangers to the expansion volumes 43, 44 and 73, and before the completion of the stroke valve 50 is closed so that the gas in the machine undergoes initial expansion and cooling. With the displacers in their topmost positions valve 54 is opened to give rise to further expansion and then the displacers move downwardly to discharge the gas from the machine via the regenerators and heat exchangers to the receiver 52. In the modification of Fig. 11 the stepped inner housing is omitted, the displacer comprises only two stages, the outer housing 118 is of frusto-conical form and the heat load comprises the tubing 94, 95 of a Joule-Thomson system which tubing is arranged in the space 136 between housing 118 and an outer housing 122 and is also cooled by the refrigerant returning from the load 114. Refrigerant is supplied to the tubing 94, 95 by a compressor 108 via cooler 109 and receiver 138 and is withdrawn from space 136 through line 106 and receiver 139. Compressor 108 may communicate with the inlet of compressor 56 in a modification similar to that shown in Fig. 11 but having stepped outer and inner housings (Fig. 8, not shown).

Title: Process for the conversion of normally gaseous hydrocarbons into liquids
IPC: C07C9/14
Filed: 1937-07-29
Abstract: A normally gaseous mixture consisting of paraffins selected from the group of propane, butanes and pentanes is partially converted into olefines in a first stage by heat and pressure, the products separated into fixed gases comprising minimum amounts of hydrocarbons of more than two carbon atoms, liquids which are removed, and intermediate products comprising hydrocarbons of more than two carbon atoms and preferably all the propene and butenes, which products are subjected in a second stage to thermal polymerization under superatmospheric pressure to produce gasoline which is separated from the hydrocarbon gases at least a part of which is returned to the first conversion stage.  The gaseous paraffins are heated in a tubular coil of restricted cross-section to 482-872 DEG  C. at pressures from subatmospheric to several hundred atmos.  The gases pass through an enlarged chamber, in which further conversion occurs and liquid products are removed, to a condenser in which gases of 2 carbon atoms or less are separated from liquefied C3-C5 hydrocarbons. The gases are washed with an absorption medium and then discharged, the said medium being treated to recover dissolved hydrocarbons which are mixed with the liquefied C3-C5 hydrocarbons and fed to the polymerizing stage.  This comprises a tubular coil of restricted cross-section heated to 260-649 DEG  C. at substantially above 10 atmos., e.g. 34 atmos. or more.  The products pass to an enlarged chamber in which the reaction is completed and tarry matter is separated.  Part of the hydrocarbons may byepass the coil and pass directly to the chamber.  The gases and vapours are led to a fractionator wherein polymers of gasoline boiling range are condensed.  The residual gases may be returned directly to the primary pyrolysis stage or in part to this stage and in part to the polymerization stage.  Alternatively they are partially liquefied and the liquefied part recycled, light gases being removed.  The gasoline may be stabilized and the released gases also recycled.  The Specification as open to inspection under Sect. 91 comprises also the subject-matter of Specification 499,843.  This subject-matter does not appear in the Specification as accepted.
