Abstract

A system and method for dispensing an injection material to an injection point. The injection material is stored in a tank and disposed to parallel piped vessels. An orifice is disposed in piping connected to discharge ends of the vessels, and has an opening with a designated cross sectional area. A high pressure fluid drives the injection material to the injection point; the pressure of the high pressure fluid is regulated with a pressure control valve. Valves in the inlet and discharge piping connected to the vessels are selectively opened and closed so that injection material flows to and from the vessels. Vessels vent to a recycle/recovery system to reduce vessel pressure enabling refilling with injection material. Valves in the pressurizing and depressurizing lines are selectively opened and closed to depressurize and refill the vessels to have continuous chemical injection to the injection location.
