Abstract: A lubricating oil composition useful for a diesel-powered engine is provided that reduces NOx emissions level produced from a diesel-powered engine. The lubricating oil comprises a base oil and at least one oil-dispersible source of HNCO such as isocyanates. A method of operating the diesel powered engine using the lubricating oil is also provided.

Abstract: The invention relates to a process for the preparation of a low-base number calcium sulfonate that is essentially chloride free. The process involves preparing a sulfonic acid solution by adding a solvent to a sulfonic acid, optionally removing dissolved or entrained SO2 or SO3, mixing the solution with a specific amount of water and calcium hydroxide, heating the mixture, separating out excess calcium hydroxide from the mixture, removing the solvent and recovering the calcium sulfonate product in oil.

The process involves preparing a sulfonic acid solution by adding a solvent to sulfonic acid, removing dissolved or entrained SO2 or SO3, mixing the solution with a specific amount of water and calcium hydroxide, heating the mixture, separating out excess calcium hydroxide and calcium salts from the mixture, and recovering solvent and oil to capture the calcium sulfonate product.

Abstract: An atmospheric distillate stream is combined with a calculated amount of lubricant extract stream. This well-mixed stream is then hydrotreated to yield a non-carcinogenic, high aromatic process oil. A desired level of high aromatic lubricant product streams and having the desired solvency properties is achieved by varying the feed stream ratio and hydrotreating conditions.

Abstract: A portion of the feed line to a distilling column/flasher (or the like apparatus) is used as a flow-through cyclone to separate vapor and liquid components of the feed. Vortex flow is induced in the flasher feed line with a swirl vane assembly having drainage slots in the bottommost portion thereof for preventing entrapment of liquids therein. A shave-off device at the discharge end of the flasher feed line minimizes re-entrainment. The shave-off device includes a short cylinder, slightly smaller in diameter than the feed line and arranged coaxially therewith to form an annulus, which leads to a circular liquid collection chamber and collection chute draining into the flasher unit. Covers are removable for cleaning. The purpose of the shave-off device is to remove the liquids from the wall of the transfer (flasher feed) line in such a way that re-entrainment of liquids is minimized. The non-intrusive nature of the shave-off device minimizes vapor phase pressure drop.
