Abstract
A system is provided for introducing gas bubbles (usually air bubbles) into a liquid stream to coalesce material such as unwanted bits, or particles, of hydrocarbons that lie in the liquid stream along with wanted dissolved bits of metal, for removal of the hydrocarbons. The system is constructed to produce a large number of bubbles of an optimum range such as 60 to 100 μm which best coalesce the hydrocarbons. A controller receives the outputs of sensors such as pressure and flow rate sensors (P, F) and uses them to make changes in other parameters such as the pressure of air introduced into the liquid stream and the pressure in a third conduit of the liquid-bubble stream.
