Condensation recovery and adsorption recovery are the two main routes for solvent recovery, with different applicable concentration ranges and operating logics. This article compares the recycling objects, concentration adaptation, operating costs, and combination applications from four dimensions for reference when selecting.
2026-10-19Abnormal pressure can be divided into two categories: those that cannot be lifted up and those that cannot be lowered down. The former involves checking pumps and seals, while the latter involves checking blockages and valves. Safety valves only operate when overpressure occurs. This article explains the classification and troubleshooting sequence, as well as instrument verification.
2026-10-18The increase in resistance is the leading signal of blockage, and the three most common types are the increase in pressure difference in the adsorption bed, the accumulation of liquid at the low point of the pipeline, and the blockage of the filter. This article explains the troubleshooting and disposal according to the principle of "easy first, difficult later".
2026-10-18The release of halogens from halogenated hydrocarbons accelerates corrosion. This article explains the key points of corrosion resistance in material selection, process matching, and daily maintenance.
2026-10-17The absorption method uses liquid absorbents to capture the solvent vapor in the exhaust gas, enriching the low concentration, high air volume gas phase into a low flow, high concentration liquid phase, and then recovering the solvent through distillation or stripping regeneration. This article outlines the process principles, applicable scenarios, and key operational control points of absorption method.
2026-10-16Boosting the pressure to increase the dew point of the components and allowing shallow cooling can condense most of the solvent, while providing permeation driving force for membrane separation. This article explains the division of labor and configuration points of each section.
2026-10-15The condensation temperature is set according to the target concentration of exhaust gas and dew point of components, with a subcooling margin. After operation, it is adjusted according to actual measurements. This article explains the logic of setting and the strategy of adjusting according to the medium.
2026-10-14Before starting up, establish pre-processing and vacuum before feeding. When stopping, cut off the material first, then release the pressure and stop the pump. If the order is wrong, it may damage the membrane or pump. This article provides executable start stop points.
2026-10-13Membrane open treatment, no adsorption heat accumulation, operation does not accumulate static electricity, compared with activated carbon adsorption in the gas station flammable scene safety is better, this paper clearly on both sides of the safety mechanism.
2026-10-12The investment and operating costs of membrane separation devices should be calculated according to the full cycle, and the key variables of investment composition, energy consumption level and economic impact are disassembled in this paper.
