Technology comment
The specific processes include: (1) Air separation for oxygen production: producing low-pressure oxygen in an air separation unit for use in the gasification unit; (2) Coal gasification process: feeding coal feedstock into the gasifier to produce raw synthetic gas via a water-coal slurry gasification process; (3) Water-gas shift process: employing a sulfur-resistant partial shift process to adjust the H2:CO ratio (2:1) in the raw synthetic gas using CO; (4) Removal of acidic gases such as H2S, COS, and CO2 from the gas stream, then directing the purified synthetic gas to the ethylene glycol unit; (5) Separating CO through a deep cooling unit, and sending the purified hydrogen-rich gas to a PSA hydrogen production unit to generate hydrogen; CO within the ethylene glycol unit. , H2 and low-pressure oxygen are used in the synthesis of dimethyl oxalate, purification, ethylene glycol synthesis, distillation, and other processes to produce ethylene glycol and its by-products.
