Talk about the gas production process you use
Natural gas steam reforming, the Calog process. After desulfurization, the raw natural gas undergoes primary conversion and secondary conversion; excess air is introduced into the secondary furnace, which serves to reduce the methane content in the process gas and to supply the nitrogen required for ammonia synthesis. In this way, hydrogen and nitrogen for the production of synthetic ammonia can be obtained, and then the carbon monoxide content is reduced through conversion.
Our company currently uses the SHELL gasification process as well as a fixed-interval gas production method; the latter is set to be converted to an oxygen-enriched continuous gas production system.
We employ the Kellogg process: raw gas is pre-desulfurized and desulfurized, followed by methane steam reforming in the first and second reactors; thereafter, the required syngas is produced through a shift process and a decarburization process.
Our three plants all use fixed-bed batch gas production methods; we plan to install a 300,000-ton capacity continuous gas production system with four nozzles.
Our 12 gas generation furnaces use a fixed intermittent gas production method; the furnaces are mainly of the 2610 type
We produce gas from Texaco water-coal slurry
In the first phase of our plant, 9 gas generation furnaces were used for fixed-interval gas production; these furnaces have a capacity of 36,000 each； Phase 2 uses Texaco Shell water-coal slurry gas generation.
Natural gas steam reforming, Calog process.. The process is the same as that on the first floor
Our plant’s gasification process is atmospheric pressure fixed-bed batch gasification; due to the outdated nature of this process, a new ammonia synthesis system is now being installed, with the gasification stage utilizing pressurized coal slurry gasification.
There are essentially two methods for gasification using coal as raw material: 1. Steam reforming, 2. Partial oxidation
Our plant uses a fixed-bed batch gas production process, with gas generation furnaces that are 2800 cone-shaped jacketed reactors.
What this gentleman is talking about seems to be the gas generation equipment used in Jinfeng’s “3652” project. The output of 2610 model is higher than that of 3000 model; it’s high-quality domestic equipment, produced in Shandong. Jinfeng’s “3652” model uses a 12+2 configuration, and it also produces 30wt of NH3. Coal-based fuel is more than twice as expensive as gas-based fuel, so I really envy those who use gas-based fuel
Our plant employs three types of gasification processes: 1. Atmospheric pressure fixed-bed batch gasification, full low-temperature shift purification, and one-axis two-diameter ammonia synthesis tower； 2. Texaco gasification, NHD desulfurization and purification, one-axis two-diameter ammonia synthesis tower ； 3. New type four-nozzle opposed gasification, NHD desulfurization and purification, Cassali ammonia synthesis tower.
Our plant uses 10 gas generation furnaces for the synthesis of ammonia, employing a fixed intermittent gas production method; the furnaces are mainly of the 2610 type； Methanol is produced using a fixed intermittent gas generation method with 10 gas generators, which are mainly cone-shaped 2610/2800 type furnaces.
