Abstract: Process for the preparation of an aqueous tar suspoemulsion by mixing a mixture including (a) a viscous tar composition formed from a tar, from inorganic solids and, optionally, from water, (b) water (W), (c) a surface-active agent (SA) exhibiting an HLB of at least 10 and, optionally, (d) a thickening water-soluble polymer (TWP) with a molecular mass of greater than 10,000, the relative amounts of constituents (W), (SA) and, optionally, (TWP) being such that the viscosity of the (W)+(SA)+optional (TWP) mixture is preferably equal to or greater than the viscosity of the said tar, and then optional dilution of the mixture obtained with water or with an aqueous acidic solution. The process is particularly advantageous when applied to to the residues, containing sulphuric acid, resulting from the synthesis of white oils from petroleum fractions. The present invention further relates to a method for fluidizing acidic tars/sludges including contacting the tar/sludge with sulfuric acid and a surfactant. Optionally, a carrier for the surfactant's incorporation into the tar/sludge can be utilized. This provides an effective process for cleaning sulfuric acid tars/sludges from containers/vessels such as transportation containers, pipes and storage tanks. Preferably, the process includes the additional step of regeneration of sulfuric acid from the fluidized tar/sludge.

Abstract: Disclosed is a method for removing sludge in a crude oil storage tank by use of thermal oil discharged from a distillation tower of an oil refinery, such as atmospheric residue, vacuum residue, or vacuum gas oil, and recovering oil having various applications by separating inorganics therefrom. The method is advantageous in terms of minimizing air pollution because of utilizing a closed system, drastically reduced washing time of crude oil storage tank, and continuous removal of the sludge. Additionally, the recovered oil can be provided as fuel oil, marine oil or a feed for secondary treatment processes, such as up-grading processes of heavy oil.

Abstract: A process for treating nitrogen-containing, substantially paraffinic product derived from a Fischer-Tropsch process. The substantially paraffinic product is purified in a purification process to lower the concentration of oxygen, nitrogen, and other impurities. The nitrogen content of the purified product is monitored, and the conditions of the purification step are adjusted to increase nitrogen removal if the nitrogen content of the purified product exceeds a preselected value.

Abstract: A process for the desulfurization of hydrocarbonaceous oil wherein the hydrocarbonaceous oil and a recycle stream containing sulfur-oxidated compounds is contacted with a hydrodesulfurization catalyst in a hydrodesulfurization reaction zone to reduce the sulfur level to a relatively low level and then contacting the resulting hydrocarbonaceous stream from the hydrodesulfurization zone with an oxidizing agent to convert the residual, low level of sulfur compounds into sulfur-oxidated compounds. The residual oxidizing agent is decomposed and the resulting hydrocarbonaceous oil stream containing the sulfur-oxidated compounds is separated to produce a stream containing the sulfur-oxidated compounds and a hydrocarbonaceous oil stream having a reduced concentration of sulfur-oxidated compounds. At least a portion of the sulfur-oxidated compounds is recycled to the hydrodesulfurization reaction zone.
