Dry Solvent Recovery Plant
Main Features
Dry process production line emissions except DMF also contains aromatic, ketones, lipids solvent, pure water absorption on such solvent efficiency is poor, or even no effect. The Company developed the new dry solvent recovery process, revolutionized by the introduction of ionic liquid as the absorbent, can be recycled in the tail gas of solvent composition, and has the great economic benefit and environmental protection benefit.

DMAC Solvent Recovery Plant-New Technology
MAC, as an excellent polar solvent, is widely used in polyurethane, pharmaceuticals, pesticides, high molecular membranes (such as PVDF), and electronic chemicals. However, DMAC has certain toxicity and poor biodegradability, and its waste liquid must be effectively treated and recycled. Traditional recovery methods (such as ordinary distillation) have problems such as high energy consumption, limited product purity, and easy decomposition. This article will focus on...

DCS Control System
System Description DMF recovery process is a typical chemical distillation process, characterized by a large degree of correlation between process parameters and a high requirement for recovery indicators. From the current situation, the conventional instrument system is difficult to achieve real-time and effective monitoring of the process, so the control is often unstable and the composition exceeds the standard, which affects the production efficiency of enterpri...

DMF Effluent Recovery Plant
General Description This proposal is designed for the recovery of DMF effluent generated during process of RO membrane production. Due to the low effluent concentration (~5%), considering the operating cost of the DMF effluent recovery equipment, the process flow is designed based on a three-efficiency energy-saving process, including two-stage concentration and dehydration, one-stage distillation and one-stage deacidification and refining. At the same time, the en...

PLC Control System in DMF Recovery
1. Process Overview: What is DMF Recovery? DMF is a common industrial solvent. Due to its cost and environmental regulations, it is often recovered from waste streams (e.g., from pharmaceutical or synthetic leather industries) rather than disposed of. The most common method is Distillation: Feeding: The waste DMF mixture is pumped from a storage tank into a distillation column. Heating: The mixture is heated in a reboiler. DMF has a higher boiling point than water a...
