Distribution problem of heat exchange conversion load
Thread Content
In the heat exchange conversion process using natural gas as raw material, what is the maximum percentage of the heat exchange conversion load that can reach the total conversion load?
The pure oxygen for the second stage combustion is 30 to 35%, and the oxygen-enriched air for combustion is about 35 to 40%.

The one-stage and two-stage heat exchange conversion process of synthetic ammonia, the second stage directly adds air for conversion, and the converter load can be controlled at 30-45% of the total load. Two such devices in our unit are controlled according to this, and the production is stable.
sjxx30(UID: 570808) Brother, which company is yours? I don’t know the size of your device, which company you use for the heat exchange furnace. If the load of the heat exchange furnace reaches 40%--45%, what is the reaction situation, what is the water-to-carbon ratio, is there carbon precipitation, and which company’s catalyst do you use?

Carbon precipitation can only occur when the water-to-carbon ratio is seriously insufficient. Therefore, a water-to-carbon ratio of 3.8 cannot produce carbon. The methane content at the converter outlet is also related to the activity of the catalyst. It can reach 12% at best. Under normal circumstances, the export methane is 12%-15%. Our process indicator is to control the methane content at the converter outlet.
