The project is located in Ordos, Inner Mongolia, and mainly produces silicon manganese alloys. Its products are mainly exported. The whole plant has 4 plants and 1 gas storage station. Among the 8 pipelines that transport gas from the 4 plants, 4 directly lead to the gas storage station, which then leads to the gas storage cabinet. The whole gas holder station has been the exemplary organization of the plant for its clean on-site environment and standardized operation.

The project company has created a project package for a 5-megawatt power plant with an annual output of 60000 tons of carbon based compound fertilizer using its rice husk and other biomass gasification multi generation technology. The biomass gasification raw material is rice husk, which can be used for gas production, power generation, grid connection, and internal production. The project does not consume any other energy and does not pollute the environment. Our online gas analysis system is used on the project site to monitor the gas composition of the gasifier.

At Benxi Iron and Steel Plate Special Steel Plant in Liaoning Province, the rolling mill is forging automotive panels with millimeter level precision. However, the energy source supporting this precision rolling - the mixed gas of the heating furnace, has a complex composition, volatile calorific value, and unstable gas supply pressure. Traditional measurement methods are powerless in the face of pressure changes, and the mixture of coke oven gas and converter gas (hereinafter referred to as "coke to gas") that has not been uniformly mixed makes it difficult to accurately control combustion efficiency.

Driven by the transformation of energy structure and the goal of "dual carbon", the modern coal chemical industry is accelerating its development towards clean and efficient direction. As an important national energy base, Inner Mongolia promotes clean utilization technology of coal, among which the Degushi coal water slurry gasifier has become the core equipment of large-scale coal chemical projects due to its strong adaptability to coal types (able to handle inferior coal) and high carbon conversion efficiency.

Driven by the "dual carbon" target, the national "14th Five Year Plan for the Development of Bioeconomy" clearly proposes to promote the energy utilization of agricultural and forestry waste. In 2023, the National Energy Administration will list biomass gasification power generation as a key direction for promoting renewable energy technology. Currently, the industry is accelerating the transformation from traditional extensive gasification to efficient and clean, but accurate monitoring of high dust and multi interference gasifier export synthesis gas has become a key bottleneck restricting process optimization.

The steel metallurgy industry is an important basic industry in the country, and its production process is accompanied by a large amount of combustible gases such as blast furnace gas and converter gas, which are flammable, explosive, and harmful to human health. Gas leakage is one of the major safety risks for steel enterprises, and once an accident occurs, the consequences are extremely serious. In recent years, national and local safety production regulations have put forward higher and stricter requirements for the safety of gas operations. Multiple regulations explicitly state that personnel should carry portable detection and alarm devices when entering gas areas for work, and check the gas content in the workplace before operation to ensure compliance with safety standards before entering the work area.

The main business of the project owner is the research and application of biomass gasification technology, biomass power generation, and heat supply. The biomass gasification and reburning power generation industrial demonstration project currently operated and managed by the company is a coal-fired power plant boiler straw gasification and reburning system industrial demonstration project. The project has formed a biomass electricity chemical cycle industry, doubling the processing capacity of domestic biomass circulating fluidized bed gasifiers and pioneering the application of biomass gasification reburning power generation technology to modern large-scale thermal power generation units.

Metal organic chemical vapor deposition (MOCVD) is the core process for preparing III-V compound semiconductors, such as gallium nitride (GaN), which relies on precise control of precursor gas concentration, growth rate, and process repeatability. To achieve process optimization, real-time monitoring of precursor concentration is required, and closed-loop control is formed by feedback adjustment of gas flow rate, temperature, pressure and other parameters. As a manufacturer of infrared gas sensors, Sifang Instrument has launched the Gasboard-2062 infrared gas sensor designed specifically for MOCVD, providing high-precision and real-time precursor concentration monitoring.

The exhaust gas oxidation power generation technology mixes the extracted gas with exhaust air in precise proportions to control the methane concentration within the appropriate range required by the regenerative high-temperature oxidation device (RTO), enabling stable and efficient flameless oxidation in the furnace, generating high-temperature steam, and ultimately driving the steam turbine generator set to generate electricity. This technology greatly expands the utilization boundary of low concentration gas, converting traditional hazardous waste directly discharged into clean electricity, and has significant environmental and economic benefits.

This project is located in a large new energy materials company in Hunan. A laser micro water gas analyzer provided by Sifang Instrument is installed on site, using tunable semiconductor laser (TDLAS) technology with high accuracy and fast response capability. It can stably measure moisture and efficiently match the process, effectively preventing equipment failures caused by excessive moisture.
