Process Gas Applications
Gasification or Pyrolysis
Gasification and pyrolysis are energy-intensive processes that attempt to convert carbon-based raw material such as coal, biomass (waste wood, rish husk, sawdust, sugarcane bagasse, coffee shell, Poultry litter, palm shell), RDF, MSW, plastic, tyre, etc., into more convenient energy like synthetic gas (syngas for short) or oils by controlling the conditions of temperature and oxygen level. Generally gasification occurs in low oxygen or steam while pyrolysis occurs in the absence of oxygen or other reagents. For these applications we have PCT-approved syngas analyzers with the following configurations available.

Gasboard-9021 7*24 monitoring/ sampling conditioning unit/ PLC control

Measurement of C2H2, C2H4 are recommended when the feedstock contains plastic, tyre, etc.

Steam Reforming or Steam Methane Reforming (SMR)
Steam reforming or steam methane reforming (SMR)is a method for producing syngas (mainly hydrogen and carbon monoxide) by reaction of hydrocarbons with water in catalytic reactors. Commonly natural gas, liquid gas or naphtha can be used as the feedstock. It is the most extensively used process for hydrogen production. For such process, our NDIR based syngas analyzer can be good options.

Heat Treatment
Heat treatment is the process of using heat at various, staged levels to change the physical properties of metal or alloy in a furnace. Besides heat, the furnace also requires specific operating atmospheres to ensure desired carbon content in metal or alloy. The composition of the specific atmosphere (generally it includes CO, CO2 and CH4 ) is of prime importance to these applications and must be controlled and monitored by using gas analysis systems to achieve the designed material quality and consistency. Gasboard-9021 can be a great solution.

Steel Making

Steel Making Gas Mixture /Blast Furnace Top Gas/Coke Gas/Converter Furnace Gas

Steel making is a heavy industry that involves the process of producing steel from iron ore, direct reduced iron products, and/or scrap. And Blast Furnaces dominates the production and supply of metallic units for steelmaking. In blast furnace large quantities of gas (top gas, often contains CO CO2 CH4 H2 O2)are formed at the top of the blast furnace as a result of the reduction of iron ore and the combustion of injected coal by injected blast air. Gas analysis system Gasboard-9021 is recommended to optimize the blast furnace process, including reducing the consumption rate of coke and controlling the temperatures inside the furnace.

Natural Gas
Natural Gas or coal bed gas is a naturally occurring mixture of hydrocarbon and non-hydrocarbon gases found in porous geological formations (reservoirs) beneath the earth’s surface. The chemical composition and heating value (Btu content) of natural gas can vary widely depending upon the reservoir source, processing and conditioning steps, and final treatment performed by the supplier. It is important to determine gas composition and heat value of natural gas before it is used as fuel gas or feedstock for hydrogen generation, ammonia production, and a source of light hydrocarbons for chemical synthesis. Laser Raman Gas Analyzer LRGA-3100 and LRGA-6000 can be used to tackle this hard job.

In-situ Process Gas Analysis
In some industrial processes, especially those involving stack emission, safety monitoring and controlling, instant measurement or harsh gas condition, in-suit gas analyzer will be more suitable than the extractive type gas analyzers, because it can be mounted directly at the measurement site without extra sample gas conditioning system.In-situ process gas analyzer GASTDL-3100 manufactured by Cubic-Ruiyi can provide direct measurement of O2, CO, CO+CO2, CH4 with different ranges as follows.

Biogas Analysis
Biogas can be produced via different ways such as anaerobic digestion, landfill, wastewater treatment, and it can be used for direct combustion including heating, cooling, cooking, space drying, and gas turbines. It may also be used in fueling internal combustion engines and fuel cells for production of mechanical work and/or electricity after cleaning and upgrading. For better usage of biogas and process optimization, it is important to know the biogas composition at different points during the whole process. And for different measurement points, we have different measurement solutions.
