AI Technical Summary
Existing technologies for preparing high-purity methanol suffer from problems such as complex preparation processes, high energy consumption, low economic efficiency, and difficulty in effectively removing impurities from light and heavy fractions. In particular, the trimethylamine content is difficult to meet the requirements of propylene production processes.
An integrated membrane methanol separator system is adopted, which combines mechanical cyclone separation, membrane separation and atomization absorption technology. Modified polyethersulfone microporous filter membrane and stainless steel metal fiber sintered material are used to adsorb polar impurities through multi-stage high-precision separation and electrostatic induction, thereby improving the purity of methanol.
It has achieved efficient and low-cost preparation of high-purity methanol with a purity of 99.99% and a trimethylamine content of less than 2x10-9, meeting the requirements of propylene production process, while reducing equipment investment and energy consumption.
