AI Technical Summary
In the current production process of furan ammonium salts, the generation of trans-forms is unavoidable, which increases the difficulty and cost of wastewater treatment and makes it impossible to use them directly in the finished product, thus affecting economic benefits.
A trans-isomer purification system for furan ammonium salt production is adopted, including an oxime aqueous phase tank, an extraction vessel, a decolorization vessel, a plate and frame filter press, a crude product salting vessel, a crude product centrifuge, a purification vessel, a finished product salting vessel, and a ribbon dryer. Through steps such as pH adjustment, extraction, decolorization, centrifugation, and salting, the trans-isomer is separated and recovered to form the furan ammonium salt trans-isomer finished product.
It effectively reduced the treatment cost of wastewater treatment plants, improved economic efficiency, enhanced the competitiveness of enterprises, reduced environmental risks, and achieved efficient recovery and purification of trans products.
