    摘要: Provided is a supercritical drying method of a silica wet gel blanket and a method for producing a silica aerogel blanket including the same, the supercritical drying method preventing a salt from being accumulated inside equipment during supercritical drying. By preventing a salt from being accumulated inside equipment during supercritical drying, it is possible to improve the operational stability of the supercritical drying process. In addition, since only a line filter needs to be separated and is easily washed, the time required for washing and the total amount of ammonia wastewater generated therefrom can be reduced, thereby improving efficiency and reducing costs.

    摘要: A hydrocarbon recovery system is integrated with a fluff transfer system. The hydrocarbon recovery system is configured for contacting a wet polymer fluff with a purge gas to provide a purged polymer fluff and an overhead stream, and separating a solids stream, a recovered hydrocarbon stream, and a recovered purge gas from the overhead stream. The polymer fluff transfer system is configured to receive the purged polymer fluff from the hydrocarbon recovery system and transport the purged polymer fluff in the fluff transfer system via circulation of a fluff transfer gas. The hydrocarbon recovery system and the fluff transfer system are integrated by utilizing at least a portion of the recovered purge gas from the hydrocarbon recovery system in the fluff transfer system as the fluff transfer gas and optionally utilizing fluff transfer gas from the fluff transfer system as the purge gas in the hydrocarbon recovery system.

    摘要: A sterilizing storage device may include a housing defining an interior chamber and having an opening defined in the housing to enable access to the interior chamber, the interior chamber divided into a plurality of storage compartments, each storage compartment of the plurality of storage compartments configured to slidably receive a carrier holding a plurality of laboratory consumables. A door may be affixed to the housing and selectively movable between a closed and opened position. A plurality of ultraviolet (UV) lamps may be positioned such that each storage compartment of the plurality of storage compartments receives UV light from a UV lamp of the plurality of UV lamps. At least one fan may draw air into the housing. A plurality of carriers configured to hold the plurality of laboratory consumables suspended from an upper surface of the carrier such that a distal end of each laboratory consumable hangs down into an open interior portion of the carrier. Each carrier having at least one side surface opening and at least one bottom surface opening to enable air flow and UV light to reach the distal end of each laboratory consumable.
