    摘要： This disclosure provides methods for separating multi-ring naphthenes from a hydrocarbon feedstock. The hydrocarbon feedstock includes at least normal paraffins, isoparaffins, 1-ring naphthenes attached with a paraffinic alkyl chain, and multi-ring naphthenes. The methods comprise passing the hydrocarbon feedstock and a solvent, at a temperature and pressure through a bed of an adsorbent comprising a metal-organic framework (MOF) adsorbent, to adsorb the multi-ring naphthenes from the hydrocarbon feedstock, thereby producing a base stock product that is depleted in multi-ring naphthenes. The metal-organic framework adsorbent is a porous crystalline material comprised of metal functionalities connected by organic linkers to form a repeating 2-D or 3-D lattice. The base stock product has a viscosity index (VI) greater than the viscosity index of the hydrocarbon feedstock. The methods of this disclosure upgrade Group II base stocks (also Group II+ base stocks) to Group III or Group III+ base stocks, and also upgrade Group III base stocks to Group III+ base stocks.

    摘要： An additive may be added to an oil-based fluid having at least one wax foulant therein. The additive may be or include an alpha olefin copolymer, an alkyl phenol-formaldehyde resin, an alkyl acrylate, a polyalkyl methacrylate, ethylene vinyl acetate co-polymer, ethylene vinyl acetate terpolymer, imidazoline, and combinations thereof. The additive may alter at least one property of the wax foulant as compared to an otherwise identical oil-based fluid absent the additive. The altered property may be or include the amount of wax foulant deposited, the amount of paraffinic wax dispersed, settling rate of the paraffinic wax foulant, viscosity of the paraffinic wax foulant, shape of the paraffinic wax foulant, such as but not limited to softening the wax foulant, and combinations thereof.

    摘要： A method for purifying a fluid from contaminating particles in a centrifugal separator with use of a separation aid which is of higher density than the fluid and which binds said particles, the centrifugal separator having a rotor body that rotates about an axis of rotation. The fluid to be purified is led via an inlet into a separation chamber delimited by the rotor body. Separated particles are discharged via a first outlet and clarified fluid cleared is discharged via a second outlet. The fluid being mixed with an amount of separation aid, supplied to the separation chamber. The pollutant particles are bound to the separation aid, which is forced out by the rotation of the rotor body to the periphery thereof. A small flow of separation aid and particles bound thereto are discharged from the separation chamber via the first outlet, and a flow of purified fluid is discharged from the separation chamber via the second outlet.
