ABSTRACT:
An apparatus and method for injecting chemicals into a hydrocarbon producing well is disclosed. The invention includes a vessel which is divided with a baffle into a first chamber and a second chamber. The chemical is installed in the first chamber, and a pressurized gas is injected in the second chamber. A valve is connected to the first chamber to selectively control the injection of chemical into the well as the pressurized gas urges the baffle to pressurize the chemical within the first chamber.
