ABSTRACT:
An apparatus and method for injecting chemicals into a hydrocarbon producing well is disclosed. The invention includes a valve attached to a vessel. A chemical is contained by the vessel, and a pressurized gas in the vessel pressurizes the chemical. The valve can be operated to selectively control the release of the chemical from the vessel and into the well. The pressurized gas drives the chemical through the valve and into the well without releasing the chemical into the ambient environment.
