概述 Program Overview
Ammonia is one of the important inorganic chemical products and occupies an important position in the national economy. In addition to liquid ammonia, which can be directly used as fertilizer, nitrogen fertilizers used in agriculture, such as urea, ammonium nitrate, ammonium phosphate, ammonium chloride, and various nitrogen-containing compound fertilizers, are based on ammonia. The synthetic ammonia production process mainly includes several steps such as CO shift of crude gas, removal of acid gas, methanation, synthetic ammonia and ammonia freezing.
Shandong Xinze Instrument Co., Ltd. provides a variety of process gas analysis solutions for CO, H2S, CO2, H2, NH3, and CH4 for the ammonia synthesis process.
构成 Scheme composition
The CO concentration was measured and analyzed at the outlet of the CO shift furnace with a gas analyzer.
Using total sulfur analyzer and infrared meter to measure total sulfur, H2S and CO2 at the outlet of the low temperature methanol washing tower can monitor catalyst poisoning.
A gas chromatograph is used to measure the process gas at the inlet and outlet of the ammonia synthesis tower and monitor the ammonia synthesis.

概述 Product Overview
During the 12th Five-Year Plan period, the proportion of natural gas in China's energy structure will rise from 4% to 10%. At the end of the natural gas industry chain and at all important links, online analysis of natural gas components and qualities is required to ensure that natural gas meets national standards and will play a vital role in the transfer measurement and trade settlement of natural gas.
应用 Product application
◢ Calorific value analysis application: During the industrial use of natural gas, a gas analyzer can be used to measure its calorific value to ensure the normality of other production processes.
应用 Application of gas gathering and transportation: At the natural gas ground station, crude natural gas from each natural gas well is usually transferred to a dehydration station for centralized dehydration treatment. An online water dew point analyzer needs to be installed to monitor the dehydration effect.
应用 Natural gas purification application: The raw material natural gas undergoing preliminary treatment is subjected to desulfurization / decarbonization, dehydration, dehydrocarbonization and other purification treatment in a natural gas purification plant or processing station, and the product natural gas enters a long-distance pipeline for sale downstream. Generally, an online hydrogen sulfide analyzer is required after the desulfurization / decarbonization device, and an online water dew point analyzer is installed after the dehydration device. Sometimes, the hydrogen sulfide in the raw natural gas entering the plant needs to be monitored in real time, so that the factory natural gas meets GB / T 17820-2012 standard.
◢ Long-distance transportation yards: Commodity natural gas delivered from the purification plant as fuel and industrial raw materials is distributed to industrial users and cities along the pipeline through natural gas pipelines, usually at the first, last, and compression stations of long-distance pipelines, and important transportation The gas distribution station and the city gate station need to monitor the water dew point and hydrogen sulfide of the piped natural gas in real time.
