A leak mitigation system for a fluid-cooled computing device includes an absorbent pad having a fluid sensor connected to an absorbent material. The absorbent pad is placed in a position relative to the fluid-cooled computing device to collect fluid from the cooling system. The sensor detects the presence of a fluid absorbed by the absorbent material and the leak mitigation system implements a leak mitigation protocol.

A rinse liquid remaining on a substrate after a rinsing process is replaced with a replacement liquid having a surface tension lower than that of the rinse liquid. During this replacement, a nozzle device is arranged at a nozzle upper position higher than a processing cup. The nozzle device is moved from a center to an outer peripheral end of the substrate in a horizontal direction while downwardly discharging the replacement liquid. Thereafter, the substrate is dried. During this drying, the nozzle device is lowered from a position above the center of the substrate to a nozzle lower position close to the substrate while gas is downwardly injected from the nozzle device. Further, the nozzle device is moved in a horizontal direction from the center to the outer peripheral end of the substrate while injection of gas is continued.

The invention discloses a crystal elutriation leg system and a crystal elutriation process. The crystal elutriation leg system comprises an elutriation water distribution section, a crystal mush elutriation discharging section and an elutriation settling separation section which are connected in sequence. And the elutriation water distribution section is provided with a distribution disc with special pore diameter distribution, so that elutriation water is uniformly distributed. The ascending velocity of elutriation water is designed to be larger than the maximum free settling velocity of crystals, so that the distribution disc is prevented from being blocked. In the elutriation settling separation section, the upward flow velocity of clear liquid is controlled to be smaller than the minimum free settling velocity of crystals, so that fine crystals and impurity mother liquor are elutriated, replaced and floated, and target large-particle crystals are settled and enriched in the discharging section. Through cooperative control of the three-section type structure and the key flow velocity, mother liquor impurity entrainment in a crystal product is greatly reduced, the crystal purity and granularity uniformity are improved, and the device is suitable for various crystal separation and purification systems with the solid density larger than the liquid density and has the advantages of being scientific in design, low in cost and high in automation degree.

The present invention provides a pretreatment process for a resin catalyst for synthesizing bisphenol A. The pretreatment process includes the following steps: firstly, purging the resin catalyst with gas, to remove residual liquid in the resin catalyst; secondly, allowing the vented resin catalyst to be in contact with a replacement washing solution for static replacement, and removing the replacement washing solution; thirdly, allowing the obtained resin catalyst to be in contact with a replacement washing solution for static replacement; and finally, allowing a leachate to be in contact with the resin catalyst, and removing the leachate, to obtain a pretreated resin catalyst. Water in the resin catalyst for catalytically synthesizing the bisphenol A is effectively removed, and a water content in the resin catalyst is less than 1.0 wt%; and a phenol consumption in the washing solution is reduced, material consumption and energy consumption are reduced, and therefore cost of the pretreatment process is reduced.

A liquid-driven separation system for separating hydrated organic materials from drenched mixed solid waste is disclosed. The system includes a funnel-shaped housing defining an upper, open end, a tapering sidewall defining the funnel-shaped housing, and a lower end having a smaller circumference than the upper, open end; vertically offset openings arranged along the tapering sidewall; impellers extend along a vertical axis of the housing; a drive device that rotates the impellers; and an extraction device configured to extract fractions of the mixed solid waste from the housing. A mixture of waste and water is received at the upper end of the housing. The drive device rotates the impellers causing the impellers to generate a centrifugal force such that the mixture spins within the housing and the mixed solid waste separates into fractions at least based on a density of components in the mixed solid waste, for further extraction.
