Inert gas content in the ammonia synthesis tower inlet
Thread Content
Could everyone discuss 1. what semi-water gas production technology is being used, and what the methane content is?； 2. For the ammonia synthesis tower used, what is the typical level of inert gas content that should be maintained in it?
We use a lignite Endler furnace to produce water gas, with a methane content in the gas of approximately 2.5% (V%)； The internal components of the synthesis tower are Nanjing Guochang type two-axis two-diameter components (1500mm); the inert gas content in the gas entering the tower is greater than 18%, and due to this high level of inert gases, the net ammonia content is only around 12%.
We use a fixed-bed batch gas production technology, with a methane content of 0.8%. DN1200 Guochang three-axis single-diameter ammonia synthesis tower, with 16% methane in the recycle gas. For cold-shock type internals, the ammonia net value is generally not very high.
We use a fixed-bed batch semi-coke production technology, with a methane content of 1.0%. Zhejiang University’s single-tube baffled internally-cooled insulated ammonia synthesis tower has a circulating gas methane content of 16%. The ammonia net value calculated yesterday: 12
We use a fixed-bed batch semi-coke production technology, with a methane content of 1.0%. For ammonia synthesis, two reactors are used: one of type two axes and one diameter 1000 MM in Anchun, Hunan, and the other of type three sleeves 1200 MM; the methane content is 15%
1. What technology is used to produce semi-water gas, and what is the methane content? Answer: Use coal rods with a CH4 content of 2–3%. 2. For the ammonia synthesis tower used, what is the typical level of inert gas content required in it? Answer: The φ1600 standard tower uses IIIJ internals, and the contents of inert gases in the circulating gas are generally controlled at: CH4 18~20%, Ar 5.5~5.8%.

We produce semi-water gas from Texaco water-coal slurry, with a methane content of 1.0%. The synthesis tower is of the fully cooled ammonia synthesis type, and the methane+argon content is 10–15%
1. What semi-water gas production technology is used, and what is the methane content?； Our factory uses a fixed-bed batch gas generator technology to produce water gas, with a methane content of around 1.0%. 2. For that type of ammonia synthesis tower, what is the typical level of inert gas content required in the feed? Our plant uses three-bed, two-cooling radial mixed-flow synthesis towers (Cassali internals), with an inert gas content of 14% in the feed gas
