Significantly increase the volume of steam outbound
On the 19th, the reporter learned from Henan Xinxiang Yongchang Chemical Co., Ltd. and Shandong Linyi Yuanjing Chemical New Technology Co., Ltd. that China's first self-contained 100,000 tons of nitric acid equipment under full load was operated technically for another five months. Through breakthroughs, the output of by-product steam was increased from 1 ton/hour when driving, to 3.6 ton/hour, and further close to the standard of steam supply of French GP, which made China's nitric acid industrial core technology advanced to the world's advanced level. A big step forward.
This set of domestic nitric acid plant was put into operation on September 16, 2007 in Henan Xinxiang Yongchang Chemical Co., Ltd., indicating that our domestically-manufactured double-pressure nitric acid plant has officially entered the ranks of international advanced technology, but the amount of steam delivered and advanced The French GP company has a certain gap with the same type of device. To this end, Shandong Linyi Yuanjing Chemical New Technology Co., Ltd., which undertakes the tasks of designing, installing, and driving and commissioning the equipment, has been working hard to keep up with customers and domestic first-class equipment manufacturing company, Xi'an Shaanxi Drum Power Co., Ltd. In the short period of 4 months after the plant was put into operation, the amount of by-product steam to be delivered increased from about 1 ton/hour at the time of operation to about 3.6 ton/hour. Only the by-product steam will increase the profit for the production enterprises by about RMB 5 million per year. At the same time, the core technology of the national nitric acid industry will be brought closer to the standard of the same type of equipment of the French GP that represents the international advanced level of the industry. step.
It is understood that steam output is an important indicator of this domestic technology. Take the data before the successful improvement of the third-generation domestic unit double-pressurized nitric acid plant as an example: If the production of nitric acid per hour requires external steam 2 to 3 tons, then according to the set of equipment, steam can be delivered out at 3.6 tons/hour per hour. Around the calculation, one year is 4.8 million to 5.7 million yuan. At the same time, it also saves the costs and expenses that must be invested in the construction of an auxiliary boiler because of insufficient self-supply of steam, and the environmental protection expenses that the boilers need to pay for; the production cost is greatly reduced, and the comprehensive competitive advantage of the enterprise in the nitric acid industry is improved.
Jing Shuangwu, chairman of Shandong Linyi Yuanjing Chemical New Technology Co., Ltd., who designed the device, said that in the engineering design in 2008, the double pressurized nitric acid process technology in China will be further advanced to a new level.
