Abstract
Abstract In a process for the removal of lubricant mists and lubricant vapors from a compressed gas comprising passing the compressed gas through an oil filter and an adsorber, the improvement which comprises, after passing the gas through the oil filter, heating the gas to such an extent that any oil mist remaining therein is completely vaporized before the gas is conducted through the adsorber.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
88 words
In a process for the removal of oil mists and vapors from an oil-contaminated compressed gas comprising passing the compressed gas through an oil separator wherein liquid phase oil is removed from the gas and passing the resultant gas through an adsorber to remove gaseous phase oil, the improvement which comprises, after passing the compressed gas through the oil separator, heating the withdrawn compressed gas to such an extent that any oil mist remaining therein is completely vaporized before the withdrawn compressed gas is conducted through the adsorber.
Claim 2
Dependent Claim
88 words
In a process for the removal of oil mists and vapors from an oil-contaminated compressed gas comprising passing the compressed gas through an oil separator wherein liquid phase oil is removed from the gas and passing the resultant gas through an adsorber to remove gaseous phase oil, the improvement which comprises, after passing the compressed gas through the oil separator, heating the withdrawn compressed gas to such an extent that any oil mist remaining therein is completely vaporized before the withdrawn compressed gas is conducted through the adsorber.
Claim 3
Dependent Claim
41 words
A process according to claim 1, wherein hot compressed oil-contaminated gas is passed in indirect heat exchange relationship with the compressed gas withdrawn from the oil separator to conduct at least partial heating of the withdrawn gas from the oil separator.
Claim 4
Dependent Claim
32 words
A process according to claim 2, wherein the compressed gas, after being withdrawn from the oil separator, is first heated by indirect heat exchange with compressed purified gas exiting from the adsorber.
Claim 5
Dependent Claim
19 words
A process according to claim 3, wherein the oil-contaminated compressed gas is cooled prior to entering said oil separator.
Claim 6
Dependent Claim
19 words
A process according to claim 2, wherein the oil-contaminated compressed gas is cooled prior to entering said oil separator.
Claim 7
Dependent Claim
18 words
A process according to claim 5, wherein compressed gas leaving the oil separator is at about 10°-50° C.
Claim 8
Dependent Claim
23 words
A process according to claim 6, wherein the compressed gas is heated to about 80°-200° C. to achieve complete vaporization of the mist.
Claim 9
Dependent Claim
18 words
A process according to claim 5, wherein compressed gas leaving the oil separator is at about 20°-40° C.
Claim 10
Dependent Claim
23 words
A process according to claim 8, wherein the compressed gas is heated to about 80°-200° C. to achieve complete vaporization of the mist.
Claim 11
Dependent Claim
32 words
A process according to claim 1, wherein the compressed gas, after being withdrawn from the oil separator, is first heated by indirect heat exchange with compressed purified gas exiting from the adsorber.
Claim 12
Dependent Claim
19 words
A process according to claim 10, wherein the oil-contaminated compressed gas is cooled prior to entering said oil separator.
Claim 13
Dependent Claim
19 words
A process according to claim 1, wherein the oil-contaminated compressed gas is cooled prior to entering said oil separator.
Claim 14
Dependent Claim
18 words
A process according to claim 12, wherein compressed gas leaving the oil separator is at about 10°-50° C.
Claim 15
Dependent Claim
23 words
A process according to claim 13 wherein the compressed gas is heated to about 80°-200° C. to achieve complete vaporization of the mist.
Claim 16
Dependent Claim
18 words
A process according to claim 12, wherein compressed gas leaving the oil separator is at about 20°-40° C.
Claim 17
Dependent Claim
23 words
A process according to claim 15, wherein the compressed gas is heated to about 80°-200° C. to achieve complete vaporization of the mist.
Claim 18
Dependent Claim
26 words
A process according to claim 1, wherein a gas is recovered from the adsorber containing less than 0.01 mg of oil per Nm 3 of gas.
