  • Patent number: 5080781
    Abstract: A portable low-viscosity hydrocarbon collector incorporating an endless absorption belt for collecting low-viscosity hydrocarbon liquids from a well and pumping those liquids to the surface. The collector incorporates a plurality of rollers which may be aligned in a configuration that enables its ideal placement at any depth within a confined space such as a surface-sealed well bore. The rollers cooperate to remove the low-viscosity hydrocarbons from the endless belt without causing premature squeezing of the belt so that those hydrocarbons can be collected in a specific gravity separating receptacle for separating the hydrocarbons from any water in order to enhance the purity of the collected hydrocarbons. The collector is also provided with a single motor which drives not only the endless belt through the rollers, but also a piston pump for pumping collected hydrocarbons to the surface.
