Limited space separation and cleaning system and method

摘要

A cleaning and separating system is provided for cleaning tanks (such as crude oil storage tanks), and other containers or enclosures. The cleaning and separating system invention fits within a limited space having a relatively small foot-print; preferably an 8 foot tall by 8 foot wide by 10 foot deep shipping container. Generally, wash fluid is sprayed into a vessel to be cleaned in order to form a slurry comprising liquid and solids. The slurry is then transferred to a cleaning and separating apparatus, where it is separated into liquid and solid components. The solids can be disposed of, while the liquids can be reclaimed.

1. A method for cleaning a hydrocarbon production vessel, separating fluids and reintroducing separated fluids into said vessel comprising:
a. cleaning said vessel, wherein said cleaning comprises:
i) spraying wash fluid into said vessel to form a slurry comprising liquid and solids;ii) pumping said slurry to a cleaning and separating apparatus wherein said cleaning and separating apparatus further comprises:
aa) a wash fluid supply connected to a pressurized sprayer;bb) a submersible pump disposed within said vessel;cc) a slurry tank;dd) a conduit connecting said submersible pump to said slurry tank;ee) a two-phase separation device; andff) a conduit connecting said slurry tank to said two-phase separation device; b. separating said slurry into liquid and solids, wherein said liquids contain at least one hydrocarbon; c. disposing of said solids; d. transferring said separated liquids to a holding tank; and e. reintroducing said separated liquids from said holding tank into said vessel after said step of cleaning said vessel has ceased.
