July 2007: this video was shot at the end of fluidization with S.R.S.®. In the tank, only mud, sand and rust remain.
The S.R.S.® recovers more than the 95% of the hydrocarbon contained in the sludge, that is returned to the client together with the fresh oil used to fluidize it.
The subsequent hot-water washing cycle leaves only small residue, which average composition is 1/3 inert, 1/3 water, 1/3 solid hydrocarbon, and be easily disposed. No other system gives a better recovery, and a minor quantities of waste material. This means significant saving in terms of oil recovered and avoided disposal costs.
At the end of S.R.S.® operations, man-holes are opened for ventilation and workers can safely enter the tank for final removal.
This system eliminates Health and Safety risks for operators who can enter the tank when the internal atmosphere is neither flammable nor hazardous.
