Abstract
A method of treating a fluid within a process line includes flowing a treatment chemical and a first volume of the fluid into an injection chamber of a process pump, exerting an upward force on a lower cylinder of a piston of the process pump with a mixture of the treatment chemical and the first volume of the fluid within the injection chamber, exerting a downward force on an upper cylinder of the piston with a second volume of the fluid, and transmitting the downward force to the lower cylinder of the piston to force the mixture out of the injection chamber and into the process line.
