Abstract: A cooling nozzle assembly includes a mounting plate, a pin body and a nozzle tube. The mounting plate has a pin aperture and a fastener aperture. The pin body has a head portion and a shaft portion. The shaft portion of the pin body has a blind bore that extends from an open first end of the shaft portion to the head portion. The shaft portion of the pin body is fitted into the pin aperture of the plate and affixed to the plate. A hole is cross-drilled in the assembly to intersect the blind bore of the shaft portion of the pin body. The nozzle has an interior passage. The nozzle tube is mounted to the plate and pin body assembly by fitting it into the hole. The interior passage is in fluid communication with the blind bore of the pin body. An engine cylinder block includes a cylinder with a piston assembly disposed therein. A mounting surface is provided in the cylinder block for mounting the cooling nozzle assembly proximal to the cylinder.

Abstract: A continuous process for thermal cracking of heavy hydrocarbon oil feed to residual products having improved stability comprises passing the feed under specified conditions through a thermal conversion zone having at least two mixing stages.

Abstract: A process is disclosed for the conversion of asphaltines-containing mineral hydrocarbon oil to distillate gas oil by a processing sequence comprising thermal cracking, flashing, atmospheric fractionation, vacuum fractionation, thermal cracking, catalytic cracking or hydrocracking, and atmospheric fractionation with certain recycle of intermediate streams to achieve efficient, economic operations.

Abstract: A process for the preparation of gas oil from residual oils by combination of two stages of thermal cracking, cyclone separation, vacuum distillation, deasphalting, atmospheric distillation, and recycling of certain streams.
