Issues related to the 6.5MPa conversion process
Thread Content
I earnestly request the operating procedures for the shift conversion section in the 6.5 MPa coal gasification process, as well as related parameters and information! Thank you all, guys, for helping out!
Our process gas pressure is 6.35 MPa; a gas distribution + shift process is employed, along with sulfur-resistant shift technology. The temperature inside the shift reactor is 265°, while it is 441° at the exit of the reactor. The gas flow distribution is as follows: 55% for shift reaction； Valve timing 45%. Composition of the process gas: CO: 43.71%, CO2: 19.12%, H2: 36.22% (on a dry basis); water-to-gas ratio: 1.377. Composition of the gas exiting the shift reactor: CO: 6.28%, CO2: 40.18%, H2: 52.85%. Composition of the gas exiting the shift unit: CO: 20.46%, CO2: 32.14%, H2: 46.75%
Thank you! It’s the parameters for producing methanol; are there any more?
What is the process used to produce the process gas with the gas composition you provided?
4# Pastoralist: This is the gas production from water-coal slurry; the CO content in gas produced from pulverized coal is 60%.
A transformation and gas distribution process is employed, along with sulfur-resistant catalysts. Inlet temperature: 240°C, pressure: 6.3 MPa, carbon monoxide: 43%, hydrogen: 36%. The temperature in the conversion furnace is 265°C and the pressure is 6.33 MPa. Temperature in the converter: 427°C, pressure: 6.27 MPa, carbon monoxide level: 6.7% :handshake Actively participating 1# 419423903
The temperature in the converter should be 441°C, right? The hydrogen temperature isn’t that high, is it?
