Equipment for ester solvent recovery, specifically designed for the chemical, pharmaceutical, food, printing, and other sectors, is the A20Ex ester solvent treatment equipment. Ester solvent is becoming more and more popular as an eco-friendly solvent. However, the corresponding recycling has become an essential technical technique with the usage of ester solvents. Businesses can save expenses and increase productivity by using A20Ex ester solvent treatment equipment, which also helps to preserve the environment and promote sustainable growth.

1. Application:
Ester solvents are frequently utilized in the printing, food, chemical, and pharmaceutical industries, among others. Ester solvents, for instance, are frequently used in the food industry to extract plant flavors and spices that have good fragrance characteristics, stability, and purity. They are also used in the pharmaceutical industry to make oral and liquid preparations that have good effects on dissolution, dispersion, and stabilization. Ester solvents are extensively utilized in the printing industry for thickening, stabilizing, focussing, and other items like glue and ink.

2. Ester solvent recovery process:
Waste liquid containing ester solvents is fed into the A20Ex ester solvent treatment unit for evaporation and separation. The equipment's main parts are the gas-water separator, evaporator, condenser, heat pump, purifier, and so on. To achieve the goal of recovering ester solvents, the equipment consists of a low-temperature heat pump, low-pressure steam heating compression to a high temperature, high-pressure steam, and heat exchange with the recovery device. This process vaporizes the waste liquid in the evaporator and then purifies it in the purifier. By completing the ester solvent recovery and waste liquid purification steps outlined above, the goals of environmental protection, high efficiency, energy conservation, and safety are all achieved.
