Abstract
A high throughput, positive pressure, gravity operated dewatering system for hydraulic fluids, lubricating fluids, and petroleum based fluids comprises a gravity operated dewatering chamber receiving the industrial fluid and a source of positive pressure drying air coupled to the dewatering chamber.
Claims17
A method of dewatering hydraulic, lubricating and petroleum based liquid fluids comprising the steps of:
- A) providing a gravity operated dewatering chamber configured to operate at above ambient pressure;
- B) supplying one of hydraulic, lubricating and petroleum based liquid fluid to an upper portion of the gravity operated dewatering chamber, and the chamber configured to have the liquid fluid flow through the dewatering chamber via gravity;
- C) heating a positive pressure drying gas above ambient temperature and supplying the heated positive pressure drying gas to the dewatering chamber at a position below the supply of liquid fluid in the chamber, and wherein the positive pressure drying gas is heated to a temperature that is 20-40 degrees above ambient temperature;
- D) creating an area of gas-liquid fluid interface within the chamber to accommodate transfer of water from the fluid to the heated positive pressure drying gas at above ambient pressure;
- E) venting the moisture containing drying gas from an upper portion of the chamber;
- F) collecting dewatered liquid fluid in a lower settling tank portion of the dewatering chamber.

A method of dewatering hydraulic liquid fluid from an existing hydraulic system comprising the steps of:
- A) providing a gravity operated dewatering chamber configured to operate at above ambient pressure;
- B) supplying hydraulic liquid fluid from the hydraulic system to an upper portion of the gravity operated dewatering chamber, and the chamber configured to have the liquid fluid flow through the dewatering chamber via gravity;
- C) heating a positive pressure drying gas above ambient temperature and supplying the heated positive pressure drying gas to the dewatering chamber at a position below the supply of hydraulic liquid fluid in the chamber and wherein the positive pressure drying gas is heated to a temperature that is 20-40 degrees above ambient temperature;
- D) creating an area of gas- liquid fluid interface within the chamber to accommodate transfer of water from the hydraulic fluid to the heated positive pressure drying gas at above ambient pressure;
- E) venting the moisture containing heated positive pressure drying gas from an upper portion of the chamber;
- F) collecting dewatered hydraulic liquid fluid in a lower settling tank portion of the dewatering chamber;
- and
- G) returning the dewatered hydraulic liquid fluid to the hydraulic system.

A method of dewatering industrial liquid fluid from an existing industrial fluid system loop comprising the steps of:
- A) providing a gravity operated dewatering chamber configured to operate at above ambient pressure and an industrial fluid pump coupled to the gravity operated dewatering chamber, wherein the pump is configured to operate alternatively to pump industrial liquid fluid to be dewatered from the existing industrial fluid system loop into the dewatering chamber, and to pump dewatered industrial liquid fluid out of the chamber back to the industrial fluid system loop;
- B) supplying industrial liquid fluid from the industrial fluid system loop via the pump to an upper portion of the gravity operated dewatering chamber, and the chamber configured to have the industrial liquid fluid flow through the dewatering chamber via gravity;
- C) heating a positive pressure drying gas above ambient temperature and supplying the heated positive pressure drying gas to the dewatering chamber at a position below the supply of industrial liquid fluid in the chamber and wherein the positive pressure drying gas is heated to a temperature that is 20-40 degrees above ambient temperature;
- D) creating an area of gas- liquid fluid interface within the chamber to accommodate transfer of water from the industrial liquid fluid to the heated positive pressure drying gas at above ambient pressure;
- E) venting the moisture containing heated positive pressure drying gas from an upper portion of the chamber;
- F) collecting dewatered industrial liquid fluid in a lower settling tank portion of the dewatering chamber;
- and
- G) returning the dewatered industrial liquid fluid to the industrial fluid system loop.
