US 2026/0241318 A1 · Conversion Assembly for Converting an Outside-to-inside Coalescing Filter System to an Inside-to-outside Coalescing Filter System for Air and Oil Separators and Method of Use

Abstract

A gas and oil separator filter assembly for a separator tank. The filter assembly is comprised of a tubular outer shell having gas and oil mixture inlets, a tubular inner shell positioned within and above the outer shell creating an annular flow space, the inner shell having a lower end with a central opening, and a tubular coalescing filter having an inside and an outside positioned within the inner shell above said lower end central opening whereby a flow of a gas and oil mixture is directed through the gas and oil mixture inlets of the tubular outer shell into the annular flow space and into the central opening of the inner shell into a coalescing filter. The gas and oil mixture is then filtered from the inside of the coalescing filter to the outside of the coalescing filter.

Dependent claims

A gas and oil separator filter assembly comprising:

a. a vertically extending tubular outer shell having an upper end, an outer shell wall having an outer shell gas and a lower end having an outer shell baseplate;
b. a tubular vertically extending inner shell having an upper end configured to create an upper filter placement passage and a lower end having an inner shell baseplate having a gas and oil fluid mixture opening, said inner shell positioned within said outer shell above said outer shell baseplate, thereby creating an annular space between said inner shell and said outer shell and a flow space between said outer shell baseplate and said inner shell baseplate;
c. a plurality of gas and oil mixture inlets through said outer shell wall into said annular space between said inner shell and said outer shell;
and
d. a coalescing filter having an inside and an outside, said coalescing filter positioned within said inner shell above said gas and oil fluid mixture opening of said inner shell baseplate.

In a gas and oil separator having a separator tank having an upper end and a lower end, a separator tank gas and oil inlet between said upper end and said lower end of said separator tank whereby a flow of a gas and oil mixture is introduced into said separator tank, a separated oil outlet, and a separated gas outlet, and an interior baffle wall, said oil and gas separator further comprising:

a. at least one gas and oil separator filter assembly positioned within said separator tank, said gas and oil separator filter assembly comprising:
i. a support flange;
ii. a tubular outer shell extending vertically below said support flange, said outer shell having an upper end, a lower end, an outer shell outer wall, and an outer shell baseplate at said lower end of said outer shell;
iii. a tubular inner shell extending vertically below said support flange, said inner shell having an upper end and a lower end having a lower shell baseplate having a central opening, said inner shell positioned within said vertically extending outer shell above said outer shell baseplate thereby creating an annular space between said outer shell and said inner shell and a flow space between said outer shell baseplate and said inner shell baseplate;
iv. a gas and oil mixture inlet in said outer shell wall at said upper end of said outer shell into said annular space between said outer shell and said inner shell;
v. a tubular vertically extending coalescing filter positioned within said inner shell above said central opening of said lower shell baseplate, said tubular coalescing filter having an inside and an outside;
and
b. wherein said air and oil separator filter assembly and said interior baffle wall are configured to provide a flow of a gas and oil mixture from said separator tank air and oil inlet around said baffle, into said gas and oil mixture inlet of said gas and oil filter assembly into said annular space between said outer shell and said inner shell outer wall of said gas and oil filter assembly, through gas and oil fluid mixture opening of said inner shell baseplate of said gas and oil filter assembly, and through said flow space between said outer shell baseplate and said inner shell baseplate of said gas and oil filter assembly, and through said coalescing filter of said gas and oil filter assembly from said inside of said coalescing filter to said outside of said coalescing filter.

A method for providing a coalescing filter assembly having an inside-to-outside filter flow path for a gas and oil separator comprising the steps of:

a. providing a separator tank having a gas and oil inlet whereby a flow of a gas and oil mixture is introduced into said separator tank, said separator tank having an open upper end having a cover plate attachment flange, and a closed lower end, a gas and oil inlet between said upper end and said lower end of said separator tank whereby said flow of a gas and oil mixture is introduced into said separator tank, a separated oil outlet, a removable cover plate over said cover plate attachment flange, an interior baffle, and a separated air outlet;
b. providing a gas and oil coalescing filter assembly comprising;
i. a support flange;
ii. a tubular outer shell extending vertically below said support flange, said outer shell having an upper end, a lower end, an outer shell outer wall, and an outer shell baseplate at said lower end of said outer shell;
iii. a tubular inner shell extending vertically below said support flange, said inner shell having an upper end and a lower end having a lower shell baseplate having a central opening, said inner shell positioned within said vertically extending outer shell above said outer shell baseplate thereby creating an annular space between said outer shell and said inner shell and a flow space between said outer shell baseplate and said inner shell baseplate;
iv. a gas and oil mixture inlet in said outer shell wall at said upper end of said outer shell into said annular space between said outer shell and said inner shell;
v. a tubular vertically extending coalescing filter positioned within said inner shell above said central opening of said lower shell baseplate, said tubular coalescing filter having an inside and an outside;
and
vi. wherein said air and oil separator assembly and said interior baffle wall are configured to provide a flow of a gas and oil mixture from said separator tank air and oil inlet around said baffle, into said gas and oil mixture inlet into said annular space between said outer shell and said inner shell outer wall, through gas and oil fluid mixture opening of said inner shell baseplate and through said flow space between said outer shell baseplate and said inner shell baseplate and through said inside of said coalescing filter to said outside of said coalescing filter;
c. removing said cover plate from said attachment flange of separator tank;
d. inserting said gas and oil coalescing filter assembly into said separator tank with said support flange of said gas and oil coalescing filter assembly upon said attachment flange of said separator tank;
and
e. attaching said cover plate to said separator tank over said support flange of said gas and oil coalescing filter assembly.
