Conventional Tank Cleaning


TechCorr has the robotic technology to reduce the amount of time that manpower is needed in the tank.  This is a key advantage when talking safety on large tank projects which typically have men in a confined space for a month or more removing thousands of barrels of sludge.  TechCorr can utilize robotics inside of the tank instead of manpower to perform 85% to 90% of the sludge removal.  TechCorr's Scavenger XT® 2000 is the alternative to manpower for cleaning heavy oil tanks with large amounts of sludge for removal.

  • On large heavy oil tanks with either large amounts of sludge or solids, the scavenger is the alternative to putting men in the tank for manual removal.
  • Light and camera system which feeds back to a monitor in the outside control trailer, allows the operator to have good visual of work being performed.
  • A spray nozzle with a front suction allows us to blend down sludge into a pumpable product and pump the material from the tank to outside storage tanks.
  • A non-sparking auger breaks up solids and feeds them to the suction to be removed from the tank.  This is a perfect fit for projects such as 6 oil tanks that have a large amount of hardened cat fines built up in the bottom.  This type of work is usually very labor intensive with many in tank man hours involved.
  • This eliminates the risks and hazards of confined space entry for a large portion of the project.

The robotic manway cannon is ideal for light end and high vapor tanks that can not be open during cleaning operations due to environmental or safety issues.  This piece of equipment is cost effective and prevents the risk of hazardous vapors releasing to the atmosphere.

  • The robotic manway cannon is easily installed onto the tank shell manway and performs the majority of the cleaning from a onsite control room before confined space entry is needed.
  • The robotic manway cannon is hydraulically controlled and is equipped with a camera and lighting system that feeds back to the control room so that the operator has visual capabilities for effective cleaning.
  • This technology will also work with smaller diameter oil tanks to minimize manned entry time. It is also good for use if the tanks sludge level is above the shell manway.  If the tank has a fixed cone roof or an EFR, the cannon can be installed into the roof manway to blend the sludge.  A hydraulic submersible pump will remove the blended material from the tank to a designated storage tank.
  • The Robotic manway cannon is also used to performvapor degassing in conjunction with the cleaning.  Once installed, the manway cannon seals the tank back off as if the manway were still in place so that vapors are not emmiting from the tank while the cleaning is being performed. With the use of chemical treatment mixed with the diluents, we can perform vapor encapsulation and degassing of the tanks internals.

Chemical treatment of tanks are great alternatives for turning what is normally a waste into a marketable product. Asphalt tanks are prime candidates for chemical circulation.  With the use of a circulation system and chemical additives, TechCorr can turn asphalt bottoms back into a clean oil which will remain in an oil state even when cooled to low temperatures.  This oil can then be routed back into the plant system or sold as a good fuel or bunker oil.  With this process, the need for disposal is completely eliminated and gives a product with value back to the facility.

TechCorr also utilizes chemical treatments for emulsion breaking, phase seperations, vapor controls(such as H2S, benzene, etc.), parafin control and neutralizations of hazardous substances such as iron sulfides.

Microbial cleaning is an effective means when final detailing a tanks internals.  With the use of microbials mixed with the water, the oil residue is stripped from the pours of the metal and the wash water is easily disposed of due to the microbials attacking the oil phase.
