Through the optimization of the oxidation process and the adjustment of process parameters, the new technology allows the product, terephthalic acid (TA), to crystallize only in the crystallizer. During the crystallization, the raw material, p-xylene (PX), and the reaction intermediate materials are completely Oxidation to terephthalic acid, so TA crystal does not contain 4-CBA and p-TA two impurities. After the TA is washed and dried, the PTA product is obtained.
Since the new technology omits the refining process, the energy consumption of fuel power is reduced by 50-55%, and the average energy consumption per ton of PTA products is about 90-100 kg of standard crude oil. Due to the new process, the consumption of paraxylene (PX) raw materials is reduced, the consumption of acetic acid (HAc) solvents is reduced, and the product quality is improved. The average cost per ton of PTA products reduces production costs by 800-1000 yuan.
For newly constructed PTA installations, investment costs are reduced by 30-35%.
New PTA Technology Eliminate Refinement Process Reduces Investment Costs
The PTA production process mainly includes oxidation and refining, while the new technology omits the refining process.
