Systems and processes for hydrotreating, splitting, and extracting a gasoil feed to produce a saturate-rich feedstock for olefin pyrolysis are provided. A gasoil feed is provided to a hydrotreating section to produce an ultralow sulfur distillate (ULSD) stream. The ULSD stream is provided to a splitter section to produce a light distillate stream and a heavy bottom stream. The light distillate stream is provided to an extraction section to produce an aromatic-rich extract phase and a saturate-rich raffinate phase. The raffinate phase is mixed with the heavy bottom stream to produce an olefin pyrolysis feedstock having a reduced BMCI as compared to the gasoil feed stream and the ULSD stream.

Provided is a supercritical fluid apparatus including: an analysis flow path through which a mobile phase flows; a back-pressure control valve provided at a downstream end of the analysis flow path to adjust pressure in the analysis flow path to a predetermined pressure; a small-diameter pipe connected to the outlet of the back-pressure control valve, having an inner diameter allowing internal pressure to be maintained at a pressure higher than the atmospheric pressure; a large-diameter pipe connected to a downstream end of the small-diameter pipe, having a larger inner diameter than the small-diameter pipe; and a large-diameter pipe heating part for heating the large-diameter pipe.

Methods for creating concentrated plant material solution are disclosed. Some examples include combining at least a concentrated plant material, at least one terpenoid compound, and a solvent to define a mixture; heating the mixture, wherein a temperature of the mixture is heated above a boiling point of the solvent and wherein the temperature of the heated mixture does not exceed a lower one of a boiling point of the concentrated plant material and a boiling point of the at least one terpenoid compound; and maintaining the temperature of the mixture above the boiling point of the solvent and below the lower one of the boiling point of the concentrated plant material and the boiling point of the at least one terpenoid compound until the amount of solvent remaining in the mixture reaches a predetermined concentration level.

The present document describes a system and a process for the extraction of several products from apple peel. There are several unit operations involved including an ultrafiltration unit, concentration unit, and a three stage counter current separator centrifuge wherein water is used as the solvent. The final products that are extracted from apple peel include pectin, syrup, fibers, as well as soluble and dried retenate fractions.

A blood treatment apparatus having an extracorporeal circuit has a dialyzate circuit with a dialyzer, having a blood-side chamber, and a dialyzate-side chamber separated from the blood-side chamber by a membrane. The blood-side chamber is in fluid communication with the extracorporeal circuit and the dialyzate-side chamber is in fluid communication with the dialyzate circuit, and the apparatus has a preparation unit for online preparation of a solution. The apparatus has a first means for carrying out a priming mode and a second means for carrying out an initial treatment mode. The first means is configured to control the preparation unit to prepare a flushing solution having a pH of 7.3, with the extracorporeal circuit being filled with the flushing solution. The second means is configured to control the preparation unit to prepare the dialyzate having a pH of 7.3, with the dialyzate circuit being filled with the dialyzate.

Systems for extracting solute from a source material are shown and described. The systems may include: a first fluid pathway comprising a solvent source arranged to receive and provide solvent and a solvent conditioner. The solvent conditioner is arranged to receive liquid solvent, condition received liquid solvent by maintaining or establishing a pressure and/or temperature of the received liquid solvent and provide conditioned liquid solvent. The systems may further include a canister adapted to contain plant material and arranged downstream of the first fluid pathway, thereby producing an extract solution of the conditioned liquid solvent and the essential oil extracted from the plant material.

An improved contactor/separator process is presented where one or more stages of contact and separation is achieved by providing one or more shroud and disengagement device combinations within a vessel, where the disengagement device is connected to the top of the shroud that contains vertically hanging fibers. A liquid admixture of immiscible fluids is directed co-currently upward through the shroud at flooding velocity or greater, where all of the admixture exits the disengagement device through a coalescing material. Tray supports are used to stack additional shroud and disengagement combinations vertically within the vessel. Each tray allows less dense liquids exiting one disengagement device from a lower shroud and disengagement device combination to enter the bottom of a shroud of a shroud and disengagement device combination position vertically above the lower shroud and disengagement device combination.

The present technology relates to methodologies, systems and apparatus for separating a liquid and a gas from a multi-phase flow stream. In particular, a gas-liquid separator having a curvilinear flow path sized is described. The flow path is designed to create a shift in the axial velocity of the primary flow field through the gas-liquid separator and generate a secondary flow field effect perpendicular to the primary flow field. The curvilinear flow path can minimize additional dispersion and provide improved efficiencies in fraction collection.
