Saning chemical urea production to save energy to benefit

In the first half of the year, the Hubei Saning Chemical Urea Plant exploited the production potential through optimized processes to maximize the production efficiency of the plant, resulting in a reduction in coal consumption per ton of total ammonia alcohol up to 1100 kg and a reduction in electricity consumption below 1,240 kwh. National advanced level of similar devices.

Hubei Saning Chemical Urea Factory currently produces 300,000 tons of synthetic ammonia, 300,000 tons of methanol and 450,000 tons of urea annually. The company uses a number of advanced energy-saving and emission-reduction technologies in its production processes, such as the use of differential pressure in the carbon-carbon cycle to achieve energy recovery, saving more than 500 kilowatt-hours per year; using the company's patented low-pressure alcohol technology, methanol synthesis The reaction heat is fully recovered, and the compression power consumption per ton of methanol is reduced by 120 kWh. The thermal energy carried in the high-temperature flue gas and the combustible gas in the exhaust gas of the section such as a steam turbine is used for thermal power generation, and the annual benefit is more than 20 million yuan; through improvement Boiler fan performance can save 360 ​​kwh per hour; by optimizing the urea synthesis process, 81,000 tons of steam can be saved annually.

In addition, Sanning also adopted the most advanced DCS automation and frequency conversion technology to transform nearly 300 devices to make the devices more intelligent and stable. The company has spared every aspect of production, made energy-saving and emission-reduction benefits, and laid a good foundation for the development of circular economy.
