Abstract
Disclosed and claimed is a method of removing contaminants from a process stream or stabilizing a system parameter in the process stream. The method includes providing a filtration system in communication with a controller, wherein the controller is operable to automatically initiate a flow from the process stream into the filtration system when the system parameter of the process stream is within above an upper threshold value and/or below a lower threshold value; and activating the filtration system, wherein the flow comprises a flow rate through the filtration system and the controller is operable to adjust the flow rate.
Claims2
A method of removing contaminants from a non-aqueous process stream or stabilizing a system parameter in the non-aqueous process stream, the method comprising:
- (a) providing only one side-stream filtration system consisting of one filter, the side-stream filtration system in communication with a controller and in fluid communication with the non-aqueous process stream, wherein the controller automatically initiates a flow from the non-aqueous process stream into the side-stream filtration system when the system parameter of the non-aqueous process stream is above an upper threshold value and/or below a lower threshold value, wherein the flow into the side-stream filtration system is a percentage of the total non-aqueous process stream such that a part of the total non-aqueous process stream is unfiltered;
- (b) activating the side-stream filtration system, wherein the flow comprises a flow rate through the side-stream filtration system and the controller adjusts the flow rate.
