In an embodiment is provided a method of deoiling a feed that includes introducing a waxy feed and a deoiling solvent to a dilution chilling zone; mixing the waxy feed and the deoiling solvent in the dilution chilling zone at a temperature of from about 10° F. to about 30° F. to form a slurry; introducing the slurry to a filter zone, the filter zone comprising one or more filter stages, wherein a temperature of the slurry is from about 40° F. to about 75° F.; separating the wax from the oil and the deoiling solvent to form a wax cake in a first filter stage; and washing the wax cake in the first filter stage with the deoiling solvent to obtain a composition comprising a wax. In another embodiment is provided a composition comprising a wax.

Disclosed is a method for producing series of phase change wax products, comprising: refining a Fischer-Tropsch synthesis wax raw material via a hydrogenation reaction to obtain a refined Fischer-Tropsch wax; and subjecting the refined Fischer-Tropsch wax to reduced pressure distillation to separate continuous fractions with a distillation range of 5 C.-30 C. by continuously increasing the operation temperature so as to obtain series of phase change wax products, wherein the pressure for the reduced pressure distillation is 0-1000 pa, the operation temperature at the top of the column is 120 C.-260 C., and the phase change enthalpy value of the series of phase change wax products is 170 J/g.

A method and composition are shown for treating a variety of different substrates with a sealant coating composition which provides a long lasting protective barrier on a selected substrate. First a sealant composition is formulated by combining a micro-crystalline wax with an organic solvent pre-mixture blend. Next, the selected substrate is contacted with the sealant composition and the solvent blend is allowed to flash away, leaving behind a substantially solvent free micro-crystalline wax residue barrier. The solvent blend can be a mixture of hexane and xylene but is not limited to these two particular solvents.

The present invention relates to a method for fractionating a crude mixture comprising at least one oil and at least one wax, which comprises the following method steps: (a) carrying out a pre-fractionation stage as a layer crystallization (i) with a crude mixture comprising at least one oil and at least one wax or (ii) with a crude solvent mixture obtained by adding prior to the pre-fractionation stage at most 100% by weight of solvent relative to the weight of the crude mixture, to prepare a first fraction containing low waxy oil and a second fraction containing low oily wax, (b) carrying out a first crystallization stage including (b1) a first suspension crystallization sub-stage with the first fraction containing low waxy oil to prepare a third fraction containing dewaxed oil and a fourth fraction and (b2) after the first suspension crystallization sub-stage, a second suspension crystallization sub-stage with a mixture of the fourth fraction obtained in method step (b1) and the second fraction containing low oily wax obtained in the pre-fractionation stage of method step (a) to prepare a fifth fraction containing slack wax and a sixth fraction.

The invention discloses a sequestrant composition for application to the elimination and/or reduction of hydrogen sulfide and/or mercaptans in fluid, particularly the reduction or elimination of hydrogen sulfide from gases and liquids, including gaseous and liquid hydrocarbons, and sewage gases, especially from natural gas and liquid hydrocarbon streams. The composition uses a main scavenger agent and sequestration rate accelerator additive that also acts as a precipitation prevention agent. The use of the composition is described as being the main scavenger agent for a 1,3-dioxolane alkyl, alkenyl and/or hydroxyl derivative and ketone-based accelerator additives that include -diketones and cyclic ketones, saturated and/or -unsaturated.

Methods are provided for rapidly characterizing a feedstock being considered for lubricant base oil production in order to determine the viscosity index potential of the feedstock. It has unexpectedly been discovered that the DDVI value for a feedstock at a specified pour point can be predicted based on a) the feed distillate residual wax content at a temperature as determined by Differential Scanning Calorimetry, such as the feed distillate residual wax content at a temperature corresponding to the specified pour point temperature; b) the feed distillate refractive index; c) the feed distillate kinematic viscosity at a temperature, such as kinematic viscosity at 100 C.; and d) the distillate volume-averaged boiling point. Based on this unexpected correlation, the VI potential of a feedstock can be determined based on measurement of properties that can be performed on a time scale corresponding to one or a few days using a few milliliters of feedstock.
