An apparatus is provided for continually adding chemicals to a producing oil and gas well. A mixing chamber is provided having an inlet and an outlet. A subassembly is provided for diverting a flow of production fluid from the well and directing the flow of production fluid to the inlet of the mixing chamber. A subassembly is provided for admitting an amount of chemical into the mixing chamber. The fluid mixture of the production fluid and the chemical is exhausted from the mixing chambers through the outlet. A flow control system is provided, in fluid communication with the outlet of the mixing chamber, for permitting only a predetermined flow rate of the fluid mixture to exit from the mixing chamber. An adjustment control is provided for adjusting the flow rate of the fluid mixture through the mixing chamber to selectively increase and decrease the predetermined flow rate. An exhaust system is provided for conveying the fluid mixture from the outlet, through the flow control, and into the well. The fluid mixture flushes downwardly into the well, and is pumped upwardly through the tubing. |
