The present invention provides a process for treatment of petroleum/crude sludge for removal of bound and unbound water thereby facilitating recovery of non volatiles free product hydrocarbons in a range of about 96 wt. % to 100 wt. % along with unbound water having turbidity at least below 20 NTU. The process for treatment of sludge facilitates recovery of almost 100% solvent along with entire bound water in a range of about 99 wt % to 100 wt %. The process for treatment of sludge facilitates recovery of free water in a range of about 94 wt. % to 99 wt. %. The process for treatment of sludge also facilitates recovery of solvent to be reused in said process. The present invention further provides a process for treatment slop oil containing water, solids, salts and limited hydrocarbon content less than 10,000 PPM for recovering usable water therefrom by an effective and economically viable process. The process for treatment of slop oil is capable of bringing down turbidity value thereof in a range of 90 wt. % to 99 wt. %. |
