ABSTRACT:
A method for providing a continuous injection of a substantially constant amount of a desired treatment chemical into a flowing process stream is described. This method insures that the concentration of the desired treatment chemical is maintained at a relatively constant and effective concentration throughout the flowing process stream. The means for providing the relatively continuous injection of the treatment chemical is preferably a pump that provides a continuous injection at a relatively constant flow rate of the treatment chemical into a flowing process stream.
Providing a uniform concentration of a treatment chemical in a flowing process stream maximizes the benefit of the treatment chemical. Conventional methods for injecting treatment chemicals provide intermittent injection of the treatment chemical such that sections of the flowing process stream have no concentration of the treatment chemical. This reduces the benefit of the treatment chemical and may prevent it from providing any benefit at all.
