Methanol Precision Filter

Product Overview

Wuxi ZERRU Technology Co., Ltd. presents the Methanol Precision Filter, specifically designed for methanol (CH₃OH) production, storage, transfer, and recovery applications.
Given methanol’s characteristics — high volatility, strong hygroscopicity, sensitivity to moisture, and potential presence of mechanical impurities or by‑products — this filter utilizes high‑performance filtration media and sealing systems to ensure methanol purity, protect downstream equipment (reactors, pumps, valves, flow meters), and enhance final product quality.

Key Advantages

1. High‑precision Contaminant Removal

   • Filtration rating from 0.5 to 200 microns – effectively removes catalyst fines, rust, weld slag, polymer particles, and other solid contaminants from methanol.

2. Leak‑proof Sealing Design

   • Low‑permeability sealing materials (PTFE, modified PTFE, flexible graphite) compatible with methanol’s low surface tension – prevents leakage and solvent attack.

3. Corrosion‑resistant All‑Stainless Steel Construction

   • Housing and filter basket in SS304 / SS316L – pickled and passivated surface finish – withstands mild corrosiveness of methanol without secondary contamination.

4. High Flow Rate with Low Pressure Drop

   • Optimized inlet/outlet geometry and basket open area – single‑unit capacity from 5 to 500 m³/h with pressure drop typically below 0.05 MPa – reduces pump energy consumption.

5. Quick‑open Design for Easy Maintenance

   • Eye bolt or quick‑release clamp design – allows fast basket or cartridge change without special tools – ideal for frequent operations such as methanol tank farm or truck loading/unloading.

6. Optional Nitrogen Purge Port

   • Equipped with N₂ purge/drain connection – facilitates safe draining of residual methanol, protects maintenance personnel, and minimizes volatile losses.
