Abstract
An apparatus and method are disclosed for accumulating hydrocarbon vapor and rendering the vapor environmentally safe by combustion. An internal combustion engine is attached to an interface which accumulates hydrocarbon vapor present in the soil after a spill or leakage from a storage tank or transfer lines. The vacuum of the internal combustion engine present in the intake manifold is used to draw the hydrocarbon vapors from the soil into the interface and then into the engine where they are burned. A catalytic converter of conventional design cleans the end exhaust removing any remaining hydrocarbon pollutants.
