On May 10, the list of innovative achievements in the field of petroleum and petrochemical equipment for 2023, selected by the China Petroleum and Petrochemical Equipment Industry Association, was released in Xi’an. The “360,000-ton-per-year high-efficiency wide-condition nitric acid integrated unit” and the “Research on domestication and debugging techniques for natural gas compressor units used in offshore platforms”, both developed by Xi’an Shaanxi Gas Turbine Power Co., Ltd., won the awards for “Outstanding Innovative Achievement” and “Excellent Innovative Achievement”, respectively. “The 360,000 tons/year high-efficiency wide-range nitric acid four-in-one unit is currently the largest of its kind in China, and it is also one of the key equipment in nitric acid production plants using the double-pressure process. ”Liu Zhong, deputy general manager and chief engineer of Shaanxi Gas Turbine Power, explained that in nitric acid production, the dual-pressure process enables complete self-sufficiency in terms of energy consumption for the system by recovering the heat generated from the ammonia oxidation reaction, as well as the residual pressure and heat from the exhaust gases to power the equipment. By applying this technology, the cumulative power that can be recovered each year exceeds 30,000 kilowatts; electricity consumption is reduced by over 200 million kWh per year, generating benefits of more than 100 million yuan. The effects on energy conservation and emission reduction are significant. This technology won the First Prize for Science and Technology from the China Nitrogen Fertilizer Industry Association, and was selected as a new energy-saving and emission-reduction technology to be promoted in the nitrogen fertilizer and methanol industries during the 14th Five-Year Plan period. It is understood that China’s integrated technology for the four-in-one equipment in the nitric acid industry has long relied on imports. In order to break free from dependence on others, Shaanxi Gas Turbine Power has been making continuous efforts to localize the production of nitric acid integrated units, striving to improve its technical capabilities. In recent years, it has independently developed large-scale nitric acid production units with capacities of 100,000 tons per year, 150,000 tons per year, 180,000 tons per year, 270,000 tons per year, 360,000 tons per year, as well as 450,000–600,000 tons per year. Among them, the 360,000-ton/year nitric acid production unit based on the dual-pressure process not only increases the scale of nitric acid production but also breaks the foreign technological monopoly. It features low energy consumption, a high comprehensive utilization rate of ammonia, and a high concentration of nitric acid, and has been successfully put into operation in projects such as Wanhua in Yantai and Chongqing Huafeng. To date, SHANGGU’s \"four-in-one nitric acid production unit using the dual-pressure method\" has been installed in over 130 units across domestic and international markets, with more than 20 turnkey project installations. The company provides customers with comprehensive system solutions and services for the entire process, from ammonia synthesis to nitric acid production. The domestic commissioning technology for natural gas compressor units on offshore platforms is a commissioning service provided by Shaanxi Gas Turbine Power for foreign-made natural gas compressor units. It addresses a range of technical challenges related to surge control, dry gas seal control, and oil system control in the special operating environment of offshore platforms, filling the gap in specialized services in this field in China and ensuring the safe, reliable, and stable operation of equipment under such conditions. To date, the domestic commissioning services for natural gas compressor units on offshore drilling platforms provided by Shaanxi Gas Turbine Power have included mechanical performance tests, surge tests, and 72-hour tests for 3 sets of compressor units, all of which have now been put into operation.
