product manual

1. Brief description

Shandong Xinze Instrument Co., Ltd. provides a variety of process gas analysis products such as CO, H2S, CO2, H2, NH3, and CH4 according to different working conditions in the coal chemical, petrochemical, and chemical industries. ,经过多年的经验开发出成熟的TK-5000系列化工行业气体分析系统。 Especially for the precise measurement and analysis and control of various gas components in the synthesis of ammonia urea, petrochemical catalytic cracking, natural gas, chlor-alkali chemical industry, fuel oil production, ethylene cracking, alcohol paper production and various hydrocarbon derivatives production processes , after many years Experience has developed a mature TK-5000 series gas analysis system for the chemical industry.

The purpose of the TK-5000 online analysis monitoring system is mainly three types: 1 safety monitoring, monitoring the medium that will cause explosion danger after exceeding the standard, and the measurement results should participate in interlock control to ensure the safety of personnel and equipment. 2Process control, monitoring whether the production status of the process is normal, thereby ensuring the quality of the final product. 3Environmental monitoring, monitoring whether the components that can cause pollution to the atmosphere in the exhaust gas discharged to the environment exceed the standard, and control the pollution to the atmospheric environment during the production process.

TK-5000 chemical industry online analysis and monitoring system is mainly designed for high-pressure, explosion-proof, high moisture, oil, and impurities under the conditions of a unique gas analysis system specifically designed for process conditions. Adopt reasonable sampling technology and mature and reliable sample pretreatment system configuration to process samples with high temperature, high corrosivity, containing a large amount of water, heavy oil and solid impurities. Reliable product quality and reasonably optimized integrated solutions can ensure that the analysis system participates in closed-loop control and safety interlocking.

Industry applications

◢ 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.
