It is understood that the production process of Hubei Saning Chemical's 150,000-ton/year methanol project adopts the new low-pressure alcohol-alcohol process developed by Nanjing Panan, and the DN3400 low-pressure alcohol-alcohol NJD floating-head methanol methanol synthesis tower is the core equipment of the project, and is produced by Nanjing Panan Technology. Engineering Co., Ltd. development and design, China National Chemical Industry Group Sichuan Bluestar Machinery Co., Ltd. manufacture.
The methanol synthesis tower is "short and fat" (13 meters long, 167 tons heavy, and 3.4 meters inner diameter) and is made of materials such as 13MnNiMoNbR, 16MnR, 15CrMo, and 20MnMo. The reactor adopts a water-cooled shell-and-tube axial reactor, which has high energy efficiency, simple operation and good stability, and is particularly suitable for small and medium-sized fertilizer and methanol enterprises.
It is understood that traditional high-pressure alcohol process can increase methanol production, but due to the high working pressure (commonly 12MPa ~ 32MPa), not only the reactor design and manufacturing difficulties, and the greater resistance between the compressor segments, heat recovery effect is not ideal, Need external heat source. As methanol production increases, energy consumption will also increase. The low-pressure co-alcohol process reduces the operating pressure to 3 MPa, which can increase the monthly production of methanol by more than 300 tons. At the same time, it increases monthly high-grade steam with a value of 1.8 million yuan by-product, and monthly electricity is nearly 80,000 yuan. The monthly comprehensive benefit reaches more than 2.5 million yuan. .
In 2007, the low-pressure co-alcohol process using the DN2400 low-pressure methanol methanol synthesis tower was successfully applied for the first time in Hubei Saning Chemical's 200,000 tons/year ammonia-alcohol system, and achieved considerable benefits. Practice has proved that this process has opened up a new route for methanol production with low energy consumption, investment, and quick results. The successful development of the DN3400 low-pressure co-alcohol NJD floating-head methanol synthesis tower will bring the energy-saving and emission-reduction effects to a new level on the basis of the original technology.
The first low-pressure methanol methanol synthesis tower was successfully developed
In the past few days, the construction site of the methanol project of Hubei Saning Chemical Company was busy. The first domestic DN3400 low-pressure alcohol NJD floating-head methanol methanol synthesis tower is about to be installed and used in the 150,000-ton/year methanol project. This will not only increase the monthly production of methanol by more than 300 tons, but also use the reaction heat to produce a large amount of high-quality steam, thereby overcoming the problem of the traditional high-pressure co-alcohol process leading to increased methanol production resulting in increased energy consumption. This marks a new breakthrough in our original low-pressure co-alcohol production process.
