Methanol Purification Solution

Methanol as an essential chemical raw material has long held an irreplaceable position in industries such as fuel, chemicals, pharmaceuticals, dyes, and materials. Industrial methanol production primarily employs the catalytic hydrogenation of carbon monoxide or carbon dioxide under pressure. Depending on the feedstock, high-pressure, medium-pressure, or low-pressure processes are utilized. However, after synthesizing crude methanol, methanol purification becomes an unavoidable challenge.

The technical team at YHCHEM has extensive project experience addressing methanol purification issues, having resolved challenges such as poor purification results, inadequate removal of impurities, and low economic efficiency for multiple companies.
For instance:
01. A company in Chongqing: Crude methanol contained 91% methanol, with primary impurities being water and dichloroethane. YHCHEM's equipment achieved a purified methanol purity of ≥99.8% and a recovery rate exceeding 80%.
02. A company in Sichuan: Three feedstocks contained methanol at 70%, 15%, and 85%, with impurities including n-hexane, ethyl acetate, and chloroform. After purification, all reached 99% purity, with a processing capacity of up to 60,000 m³ per year.
03. A company in Ningbo: Raw material methanol content ranged from 40% to 45%, with primary impurities being water and hydrochloric acid. After purification, methanol purity reached 99%.

Based on the specific needs of different clients, YHCHEM offers tailored solutions, primarily utilizing single-stage packed rectifying columns. For materials with unique properties, multi-stage distillation or advanced equipment such as molecular distillation, thin-film distillation, and solvent recovery unit can be employed.
