Case Study: Application of the American SAGE thermal gas mass flow meter at Jinxin Chemical Co., Ltd. in Hulunbuir, Inner Mongolia

Thread Content

Installation date: 2013. Installation location: Jinxin Chemical Co., Ltd., Hulunbuir, Inner Mongolia. Instrument brand: American SAGE thermal gas mass flow meter. Instrument model: American SAGE SRG series thermal type. Jinxin Chemical Co., Ltd. is a Sino-foreign joint venture controlled by Yunnan Yuntianhua Co., Ltd., with **Jinxin International and **Jinxin Group holding shares in it; the company’s registered capital is 1.38 billion yuan. The company is primarily engaged in the mining, processing, and comprehensive utilization of coal resources. The company currently operates an open-pit coal mine with a mining capacity of 8 million tons per year. It has also built a coal chemical complex at the mine site, including facilities for producing 500,000 tons per year of ammonia and 800,000 tons per year of urea (referred to as the 5080 project). Additional supporting facilities include air separation units with a capacity of 36,000 Nm3/h, thermal power plants with a capacity of 25 MW, as well as dedicated railway lines. The total investment in these projects amounts to around 9 billion yuan. By July 2012, all production processes were operational, and qualified products were being manufactured. The holding company, Yuntianhua Co., Ltd., ranked 125th on the list of the top 500 listed companies in China in 2017, and 2nd among Chinese chemical industry listed companies. The American Sage thermal gas mass flow meters can be used for monitoring the flow rate of various gases such as nitrogen, hydrogen, ammonia, compressed air, natural gas, flare gas, mixtures, and air used in aeration tanks. The measurement range is 100:1, with an accuracy of 1%±. JinXin Chemical uses the SRG series of these meters, which are primarily employed for monitoring the flow rate of mixed gases. To date, they have been in use for over 8 years without any issues of stability. The newer models of American Sage thermal gas mass flow meters feature a clearer and more streamlined design in terms of their display and wiring terminals; they have a stylish and modern appearance, making flow rate monitoring simpler
