The present invention provides a method of treating a process fluid that includes assembling a modular system, flowing the process fluid through the modular system, the flowing the process fluid through the modular system including degassing the process fluid, neutralizing the process fluid, reducing an amount of one of the group consisting of entrained gases, oil and solids in the process fluid, monitoring and analyzing the process fluid for at least one of the group consisting of engrained gases, oil, and solids, and flowing the process fluid out of the modular system for disposal.
