The solvent recovery equipment improves the quality and purity of the DMSO solvent from the spinning equipment and reduces the production cost, environmental pollution, and energy consumption.

The solvent recovery equipment separates and recovers AN and DMSO from the organic solvent that comes from the polymerization and spinning equipment by distillation and evaporation. This equipment reduces cost, increases efficiency, and saves energy consumption greatly while the carbon fiber precursor production.

The solvent recovery equipment is mainly composed of AN demonomerization system, DMSO solution dehydration system, high-boiling residues concentration system, tank storage system auxiliary system with tail gas washing, and steam condensate collection.
