Abstract
A mobile vapor recovery apparatus (10) efficiently removes materials from the vadose layer of earth soil. The apparatus (10) has a plurality of intake ports (14a-14d) each configured to releasably connect to a well pipe communicating gas having vaporized materials from a well in the soil. The intake ports (14a-14d) communicate the gas to a common manifold (24). A fluid collection tank (26) receives the gas from the manifold (24) and collects fluid entrained in the gas. A blower (32) draws the gas into the intake ports (14a-14d) by forcing the gas from the tank (26) and out of an exhaust port (34). A transportable support frame (12) is configured to support the plurality of intake ports (14a-14d), the fluid collection tank (26), and the blower (32) in a self-contained transportable unit. In addition, the mobile vapor recovery apparatus (10) may be mounted within a trailer unit (82) having a locking mechanism (102).
