Abstract: A rotary vacuum drum drying system is described. The system may include a plurality of sensors and a control system operatively coupled with the plurality of sensors. The control system includes a processing device to monitor a plurality of parameters of the vacuum drying system received from the plurality of sensors and automatically adjust one or more of the plurality of parameters based on the monitor of the plurality of parameters.

Abstract: A separator includes a shell: adapted to be vertically oriented in use; a combined wet gas feedstock ingress and separated liquid egress at the bottom of the shell; a separated gas egress at the top of the shell; a first permeable, fluid flow barrier disposed within the shell at the bottom end thereof proximate the ingress and comprising a first medium; a second permeable, fluid flow barrier disposed within the shell atop and proximate to the first barrier and comprising a second medium; and a third permeable, fluid flow barrier dispose within the shell at the top thereof proximate the egress and comprising the first medium, the third barrier being dispose such that there is a gap between the second and third barriers.

Abstract: The determination of wax crystal particle size and population is used to monitor the performance of wax crystallizers used in lubricant oil processing using solvent dewaxing. The wax crystal particle size is monitored using online measurements. The information obtained from on-line monitoring is then used to control crystallization in the dewaxing equipment in order to optimize performance of the dewaxing units.

Abstract: Systems and methods for producing n-paraffins are provided. The method can include hydroprocessing at least a portion of a kerosene fraction recovered from a thermally cracked hydrocarbon product to produce a hydroprocessed kerosene product comprising n-paraffins. The n-paraffins can be separated from the hydroprocessed kerosene product to produce an n-paraffins product.

Abstract: The essence of the method is that diesel fuel is heated in the process of periodical circulation in a closed circuit including a heat exchanger and a rotor-disc apparatus of open type in centrifugal force field of which processes of mechanical destruction and dispersion run in environment of sucked air with oxygen saturation, simultaneously with processes of separation and homogenization fine filtration is carried out at a filtering porous partition of hydrophobic material with purification fineness 3÷8 micron as well as filtration at a multilayer filter-reactor at temperature 25÷45° C. which comprises granules of multifunctional catalyst alkylating aromatic compounds and a layer of fill of powder of transitional metals or their oxides. Then the treated fuel is stabilized by adding additives on the basis of surface-active substances.
