Abstract
Abstract Gas is compressed in a liquid jet compressor to high pressures, e.g. at least 7 atm, by using liquid injected under high pressure, e.g. at least 16 atm, to obtain a high velocity liquid injection into the compressor, which aspirates the gas to be compressed into the compressor.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
114 words
A method comprising the steps of axially injecting liquid under pressure of at least 16 atm into an aspirating tube, aspirating reaction gas to be compressed into said tube to contact the injected liquid therein, the velocity of said liquid contacting said gas within said tube causing said liquid to break up into droplets in said tube to form a mixture of said droplets and said gas, thereby transferring the momentum of said liquid to said gas, optionally passing said mixture into a zone of reduced velocity to thereby transfer the kinetic energy of said liquid to said gas, and obtaining as a result thereof compression of said gas to at least 7 atm.
Claim 2
Independent Claim
114 words
A method comprising the steps of axially injecting liquid under pressure of at least 16 atm into an aspirating tube, aspirating reaction gas to be compressed into said tube to contact the injected liquid therein, the velocity of said liquid contacting said gas within said tube causing said liquid to break up into droplets in said tube to form a mixture of said droplets and said gas, thereby transferring the momentum of said liquid to said gas, optionally passing said mixture into a zone of reduced velocity to thereby transfer the kinetic energy of said liquid to said gas, and obtaining as a result thereof compression of said gas to at least 7 atm.
Claim 3
Dependent Claim
21 words
A method of claim 1 wherein said gas aspirated into said tube is under a pressure of at least 2 atm.
Claim 4
Dependent Claim
24 words
A method of claim 1 wherein the volume ratio of said gas being aspirated into said tube to said liquid is less than 3:1.
Claim 5
Dependent Claim
16 words
A method of claim 1 wherein said aspirating gas is compressed to at least 25 atm.
Claim 6
Dependent Claim
26 words
A method of claim 1 wherein said gas includes a component which interacts with said liquid, whereby said compression is of the remainder of said gas.
Claim 7
Dependent Claim
12 words
A method of claim 5 wherein said component dissolves in said liquid.
Claim 8
Dependent Claim
12 words
A method of claim 5 wherein said component reacts with said liquid.
Claim 9
Dependent Claim
19 words
A method of claim 1 wherein said gas contains particulates which are removed from said gas by said liquid.
Claim 10
Dependent Claim
37 words
A method of claim 1 wherein said gas is at a temperature of at least 50° C. and said liquid contacting said gas cools said gas to a temperature of less than 40° C. during said compression.
Claim 11
Dependent Claim
23 words
A method of claim 1 wherein the injection of said liquid is through an orifice having an edge and a downstream beveled portion.
Claim 12
Dependent Claim
32 words
A method of claim 1 wherein said reactive gas is selected from the group consisting of halogen acid gases, halogen gases, aliphatic hydrocarbon gases, olefinic hydrocarbon gases and halogenated organic compound gases.
Claim 13
Dependent Claim
16 words
A method of claim 2 wherein said reactive gas is a feed to a chemical reaction.
Claim 14
Independent Claim
123 words
A method of compressing a gas feed to a chemical reaction comprising the steps of axially injecting liquid under pressure of at least 16 atm into an aspirating tube, aspirating gas to be compressed into said tube to contact the injected liquid therein, the velocity of said liquid contacting said gas within said tube causing said liquid to break up into droplets in said tube to form a mixture of said droplets and said gas, thereby transferring the momentum of said liquid to said gas, passing said mixture into a zone of reduced velocity to thereby transfer the kinetic energy of said liquid to said reactant gas, and obtaining as a result thereof compression of said reactant gas to at least 7 atm.
Claim 15
Independent Claim
123 words
A method of compressing a gas feed to a chemical reaction comprising the steps of axially injecting liquid under pressure of at least 16 atm into an aspirating tube, aspirating gas to be compressed into said tube to contact the injected liquid therein, the velocity of said liquid contacting said gas within said tube causing said liquid to break up into droplets in said tube to form a mixture of said droplets and said gas, thereby transferring the momentum of said liquid to said gas, passing said mixture into a zone of reduced velocity to thereby transfer the kinetic energy of said liquid to said reactant gas, and obtaining as a result thereof compression of said reactant gas to at least 7 atm.
Claim 16
Dependent Claim
132 words
A chemical process comprising the steps of compressing a reactant gas by axially injecting liquid under pressure of at least 16 atm into an aspirating tube; aspirating reactant gas to be compressed into said tube to contact the injected liquid therein, the velocity of said liquid contacting said gas within said tube causing said liquid to break up into droplets in said tube to form a mixture of said droplets and said gas, thereby transferring the momentum of said liquid to said gas and passing said mixture into a zone of reduced velocity to thereby transfer the kinetic energy of said liquid to said reactant gas, and obtaining as a result thereof compression of said reactant gas to at least 7 atm; and passing said compressed reactant gas into a chemical reaction.
Claim 17
Dependent Claim
132 words
A chemical process comprising the steps of compressing a reactant gas by axially injecting liquid under pressure of at least 16 atm into an aspirating tube; aspirating reactant gas to be compressed into said tube to contact the injected liquid therein, the velocity of said liquid contacting said gas within said tube causing said liquid to break up into droplets in said tube to form a mixture of said droplets and said gas, thereby transferring the momentum of said liquid to said gas and passing said mixture into a zone of reduced velocity to thereby transfer the kinetic energy of said liquid to said reactant gas, and obtaining as a result thereof compression of said reactant gas to at least 7 atm; and passing said compressed reactant gas into a chemical reaction.
