The present disclosure generally relates to methods for deoiling a hydrocarbon feed and to products formed therefrom. 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.

SYSTEMS AND METHODS FOR CAPTURING CARBON DIOXIDE AND REGENERATING A CAPTURE SOLUTION

Techniques according to the present disclosure include capturing carbon dioxide from a dilute gas source with a CO.sub.2 capture solution to form a carbonate-rich capture solution; separating at least a portion of carbonate from the carbonate-rich capture solution; forming an electrodialysis (ED) feed solution; flowing a water stream and the ED feed solution to a bipolar membrane electrodialysis (BPMED) unit; applying an electric potential to the BPMED unit to form at least two ED product streams including a first ED product stream including a hydroxide; and flowing the first ED product stream to use in the capturing the carbon dioxide from the dilute gas source with the CO.sub.2 capture solution.

DESALINATION OF SALT WATERS BY SALT REPELLENT TECHNIQUE
20230159364 · 2023-05-25 ·

A novel Salt Repellent Technique is presented to remove all inorganic salts from seawater to get potable water. The repellent additives recommended throws out all salts of sodium, magnesium, calcium, potassium and the like ions from seawater and paves way to get salt free potable water. The conventional washing of ice crystals is completely avoided due to the presence of additives. This technique helps to remove last traces of salts from seawater and analogous waters, without undertaking the conventional washing process. The new salt repellent process assures of high water recovery, ease of operation, lesser pollution, smaller plants, simpler machinery and technology, lower energy cost, nil or lesser pre-treatment and recovery of valuable by-products. To reduce the TDS still lower, it is recommended to have a simplified reverse osmosis unit in addition, as a post-operative arrangement.

Process scheme to improve divalent metal salts removal from mono ethylene glycol (MEG)

A MEG reclamation process includes the step of increasing above 2,000 ppm the divalent metal salts concentration of a rich (wet) MEG feed stream flowing into a precipitator. The increasing step includes routing a salts-saturated MEG slipstream from the flash separator it to the precipitator. The slipstream may be mixed with a fresh water feed stream, a portion of the rich MEG feed stream, or some combination of the two. The rich MEG feed stream also may be split into two streams, with a portion of the stream being heated and routed to the flash separator and the other portion being combined as above with the removed slipstream. The process can be performed on the slipstream after dilution and prior to entering the precipitator or after being loaded into the precipitator. Removal of the insoluble salts may be done in either a batch or continuous mode.

Described are liquid compositions that contain a desired (e.g., extracted) plant material such as cannabinoid, terpene, terpenoid, or the like, contained, e.g., dissolved, suspended, or emulsified, in the liquid, which contains surfactant; methods of preparing these types of liquid compositions; and methods of processing this type of liquid composition to collect, isolate, concentrate, or purify a desired target material contained in the liquid composition.

APPARATUS AND METHODS FOR DESALINATION AND MINERAL REDUCTION OF WATER RESOURCES BY VERTICAL FREEZING
20170275184 · 2017-09-28 ·

Apparatus and methods are disclosed for separating salts, minerals, organic matter and other impurities from seawater, brackish water, wastewater or other water resources by freezing contained water in a downward vertical direction. Generally, feed water is pumped into a tank and a refrigerant contacts the upper surface of the feed water to form a layer of ice. During this process, salt and other impurities are rejected from the ice layer into the feed water below. By continuing this process, the feed water will freeze in a downward direction as the ice layer thickens. Salt and other impurities will continue to be rejected into the feed water and may be drained from the tank through a drain pipe after a block of ice is formed. Additional feed water may then be pumped into the tank to raise the block of ice for removal or ejection from the tank. The block of ice may then be melted to provide product water. Multiple tanks may be arranged in multiple levels using shared pipes and conveyor platforms to increase efficiency, scale and production.

Method of cannabinoid preservation through crystallization and other crystal structures
09815810 · 2017-11-14 · ·

A method of cannabinoid preservation includes separating a cannabinoid ethanol (EtOH) mixture from a cannabis extract through a filtration process; forming a slurry by combining a crystalline compound with the cannabinoid EtOH mixture; heating and agitating the slurry in a pressurized chamber to form a colloidal cannabinoid EtOH mixture; distributing the colloidal cannabinoid EtOH mixture into a tray to form an evenly distributed mixture layer; forming an evaporation vessel for the evenly distributed mixture layer through the attachment of a detachable cover to the tray; positioning and heating the evaporation vessel within a heating chamber; performing a rapid cools process as the evenly distributed mixture layer approaches approaches saturation temperature; repeating the rapid cooling process until crystal formation is detected within the evenly distributed mixture layer; and/or removing the evaporation vessel from the heating chamber upon detection of crystal formation.
