Tank Bottom SLudge Removal

ProGreen® Sludge Removal

Heavy Solids & Slurry Removal System

Our ProGreen® Sludge Removal System enables an ordinary vacuum truck to remove the heaviest solids and sludge from tank bottoms with minimal slurrying while simultaneously degassing the vapor space, scrubbing the vacuum truck and exceeding state mandates for VOC destruction/control.
The tank bottom solids can be pulled into the vacuum truck or vacuum boxes as per the job specifications. In many instances, liquids are “sheared” from the solids due to the high velocity and increased vacuum generated during our process allowing recovery of product and/or ease of transport.
Our system can remove the heavy of solids (85% solid) and sludge during tank cleaning, while simultaneously degassing tank and the vacuum truck exhaust.

ProGreen® Tank Bottom Removal with Vapor Destruction

Moving heavy tank solids without adding extra liquid means substantial savings in liquid disposal, tank cleaning costs and tank turnaround time. The tank bottom removal process actually liquefies certain oily solids for recovery of product and/or ease of transport in many cases. RSI can extract the heavy tank bottoms with minimal cutter material due to ProGreen® Technology. ALL VOC vapors generated by the extraction process are “scrubbed” or more appropriate described, destroyed to greater than 99 destruction rate efficiency (DRE).

Key Features:

  • Removes solids 60% to 70% faster than traditional technologies when tank cleaning regulation requires vacuum truck vapor abatement
  • Meets SCAQMD and TCEQ standards for emission control
  • Drastically reduces liquids generated in slurrying solids and associated costs
  • A wide range of auto safety system shutdown alarms
  • Patented technology keeps the process Safe and Green
  • Uses 100 per cent of process vapor as the primary fuel source
  • No electrical connect or generator required
  • Process high VOC concentrations per cubic foot
  • No high risk and dangerous open flame like a thermal oxidizer

Dramatically Reduces:

  • Handling of Waste and Liquid Disposal Charges (minimal slurrying).
  • Process time - the system is continuously scrubbing while either of all processes are being used.
  • Solids removal duration - events are considerably shorter.
  • Exposure to Accidents and Spills
  • Emission of VOCs

Applications Include:

VOC vapor control, tank cleaning, and heavy solids removal for any site where petroleum products are stored in quantity. These include ships and barges, vacuum trucks, storage tanks, railroad tank cars, pipeline wastewater, heavy sludge removal, truck and trailer loading, depending on state/local regulations.
