Using Keysino KS-OTA processing system, to filter PTA oxidizing mother liquor, to realize the reuse of TA particles, acetic acid, and catalysts, within which the solid TA particles can be reused for oxidizing systems without beating, to realize the goal of decreasing PX exhaustion, decreasing the amount of oxidation residue to be processed; the filtering liquid, being transparent with no solid impurity, can increase the recycling rate of the catalyst within the oxidizing mother liquor, and lowers the cost of recovery of acetic acid. Our company’s KS-OTA processing system uses exclusive special design, fights fouling, has a long operating life, has high TA recycling rate, almost 100%. This system is applied in the oxidizing mother liquor craftwork, becoming a new clean production and energy-conserving technology.
APPLICATION CASE
One petrification enterprise produces 140m³ PTA oxidation mother liquid per hour, in which the solid TA mass action of particulate matter is about 0.25-0.50%, after clarification system, the intercepted liquid is about 100m³/h, clarification liquid is about 40m³/h, turbidity ≤1 NTU.
According to industrial operation report, this enterprise produces 900K ton of PTA annually, using KS-OTA processing system, 1000-1200 t of solid TA can be recycled annually, its recycling value, adding on the decreased oxidized residual disposal cost, produces at least 10 million RMB of economic benefits annually.
