Equipment configuration of foreign 2000 tons daily nitric acid plant
Thread Content
It is understood that a nitric acid plant with a daily output of 2,000 tons has been successfully operated abroad. So, how are ammonia oxidation furnaces and acid absorption towers similar to large nitric acid plants configured? Is it a single device or multiple devices configured in parallel?
It should be multiple devices configured in parallel! It’s better to have some understanding introduction!
Reply 1# lxq700918 I heard that in Taiwan, when multiple compressors are used in parallel, the capacity can be increased to twice the design capacity. If it is 2,000t/d, it is only 600,000t/a. This number does not seem to be very large. Because all domestic units are designed to imitate GP’s 270,000 t/a unit. The largest is the 270,000 t/a unit. There are no larger units, and domestic compressor units are not very mature, so it is better to be simple, fast, and safe. Even if three sets of units are placed side by side, it is faster than directly installing one set of 600,000 t/a. Moreover, the price of chemical fertilizers in China is always unstable, so it is better to build a large unit to make it full and hungry at times, than to build several sets of 270,000 t/a units, and operate them all when the market is good, and shut down one or two units when the market is bad. Everyone’s innovation ability and courage are still not as high as expected.
According to reports: One compressor (still from MAN TURBO), two oxidation furnaces, and one absorption tower are made on site.
“One absorption tower is produced on site”! So, may I ask?: Approximately how many meters is the diameter of the absorption tower?
7400mm is enough, but it is more difficult than 5200mm. It is said that the reactor diameter of coal-to-liquids exceeds 10m.
7400mm If the diameter is 7.4 meters, it is still relatively large. However, will its absorption pressure be adjusted compared to the current daily output of 902 tons?
The process parameters have basically not been adjusted (the 1500T/D device that has been put into production is the same as the 902), which is a personal guess.
For a device with a daily output of 2,000 tons, even if there are two oxidation furnaces, the diameter is still relatively large, right? Please tell me how much it is specifically, friends who know the situation.
There are two oxidation furnaces for sure. Take a look at Jinan Chemical Industry and Yunnan Chemical Industry.
Expert upstairs: “What is the nitric acid plant process of Jinan Chemical Industry and Yunnan Chemical Industry? What is its production scale?
