The present invention relates to a process and a system for the at least partial removal or exchange of solvent from/in a suspension comprising microfibrillated cellulose (MFC), specifically the at least partial removal of solvent from a suspension comprising microfibrillated cellulose having a comparatively high solvent (water) content to a relatively lower solvent content. Accordingly, the solids content of the microfibrillated cellulose increases during the the step of at least partial removal of solvent from a suspension comprising process, in particular from a first solids content in the range of from 0.1% weight by weight (w/w) to 6% w/w, preferably 1% weight by weight (w/w) to 5% w/w, up to a second solids content of above 5% w/w, preferably to a solids content of from above 5% w/w-50% w/w, further preferably to a solids content of from above 5% w/w-25% w/w. In a separate aspect, a solvent exchange step after the at least partial removal of a first solvent is also part of the present invention.

A process for drying wet organic solids to below 10 percent by weight is disclosed wherein an infrared drying system having a housing, a conveyor extending through the housing, at least one infrared heater located within the housing, and a fan for moving an airflow stream through the at least one infrared heater and onto the conveyor. Another step in the process can be providing and feeding wet organic solids onto the conveyor at a metering rate. In one embodiment, the wet organic solids have a moisture content of about 80 percent by weight. Moisture is removed from the wet organic solids by exposing the wet organic solids to at least one infrared heating element within the drying system and an airflow stream that has been heated by the at least one infrared heating element.

A method for separating catalyst particles from the FCC slurry oil present in the retentate of a filtered FCC slurry oil run-down stream is disclosed. The method comprises backwashing the run-down stream filter with a low boiling point solvent to extract slurry oil from the catalyst in the retentate. The backwash solution is sent to a digester where the catalyst fines are separated from the hydrocarbon component (solvent and slurry oil). The catalyst fines are collected and dried. The dried catalyst fines can be transported via pneumatic systems, and can be regenerated for further use as FCC catalysts. The solvent vapor from the drying process is collected for potential reuse. The hydrocarbon component is sent from the digester to an evaporator to evaporate the solvent from the slurry oil. The FCC slurry oil and the solvent exiting the evaporator can be independently collected. The solvent from the evaporator can be reused in the process.

A process for producing superabsorbent particles by polymerizing a monomer solution or suspension, comprising drying of the resultant aqueous polymer gel in an air circulation belt dryer, grinding, classifying, and optionally thermal surface postcrosslinking, wherein the aqueous polymer gel is introduced into the air circulation belt dryer by means of an oscillating conveyor belt and that guide devices are located at the edges of the conveyor belt.

An electrode-slurry-drying device according to one or more embodiments of the present disclosure includes a nozzle configured to spray gas to dry an electrode slurry comprising a solvent applied on a substrate; and a nozzle plate at an outlet of the nozzle, and defining perforations for discharging the gas toward the substrate, wherein a number of the perforations is determined based on an amount of undried solvent on the substrate.

A drying apparatus (1) for drying a substance (2), comprising: a drum (3) rotatable about a central axis, and having an exterior circumferential surface (7) and an interior circumferential surface (5); a belt (9) supported on the drum having a first and second side (15, 17), the belt being adapted to receive the substance on a first side of the belt, and to urge the substance via its first side towards a portion of the exterior circumferential surface of the drum when in operation; wherein one or more infrared heating elements (8) are arranged proximate to and about a portion of the interior circumferential surface of the drum for directing radiant energy to the interior circumferential surface to thereby transfer heat by conduction to the substances being urged between the belt and drum.
