Dimethylacetamide has a boiling point of about 165 ℃ and is miscible with water. It is widely used in spinning, medicine, and resin fields, with limited volatilization at room temperature and concentrated emissions in high-temperature processes. This article summarizes the characteristics of its exhaust gas, closed collection, two-stage condensation, and the key points of condensate refining and reuse, for reference by relevant enterprises.
2026-10-23For the decline of membrane flux, four reasons are distinguished: concentration polarization, gel layer, membrane pore blockage and membrane compaction. The first three are reversible and the fourth are irreversible. This paper gives identification and disposal.
2026-10-22The graded condensation uses a circulating water section to deal with high boiling point components and a chilled water section to deal with low boiling point components, balancing recovery rate and power consumption. This article explains the segmentation logic and temperature setting.
2026-10-22The flow rate of the activated carbon box is determined according to the form of the adsorbent. The apparent flow rate of granular carbon is 0.4 to 0.6 meters per second, and the carbon layer is around 400 millimeters. This article lists the key configuration points.
2026-10-22When discharging waste charcoal, the oxidation heat release can exceed 60 degrees, and outdoor drying poses a risk of spontaneous combustion. This article explains the requirements for unloading operation and storage disposal.
2026-10-22The energy consumption of the solvent recovery system is mainly from the refrigeration unit, followed by the vacuum pump. This article breaks down the energy consumption structure and provides feasible ways to reduce consumption.
2026-10-22The solvent recovery system forms an explosion-proof defense line by online monitoring of oxygen content, nitrogen replacement, and interlocking shutdown. This article explains the alarm settings, replacement standards, and interlocking logic.
2026-10-22The damage and sealing failure of membrane components are manifested as an abnormal combination of flux and selectivity. This article provides identification signals and troubleshooting methods.
2026-10-22The condenser area is configured with a margin of 1.2 to 1.5 times the amount of desorbed steam, and the acceptance check is to see if the exhaust gas temperature reaches the design value. This article explains the configuration logic.
2026-10-22The local gas collection hood is designed with a controlled wind speed of no less than 0.3 meters per second, and the air volume is calculated based on the hood mouth area and wind speed. This article explains the key design points of the collection system.
