A sulfur recovery unit converts hydrogen sulfide into elemental sulfur. The Claus process combines a thermal stage with catalytic conversion and sulfur condensation. Downstream treatment depends on the recovery target and emission requirements. Both sulfur and sulphur refer to the same element. What Is an SRU and Why Do We Need It? In refineries and … Read more

The petrochemical industry is one of the world’s most concentrated sources of VOC emissions. From refining units and tank farms to loading and unloading systems and separation towers, VOCs permeate almost the entire production chain. These waste gases are typically complex in composition, fluctuate greatly in concentration, and are often flammable, posing a severe challenge … Read more

With the continuous development of modern industrialization, more and more manufacturing enterprises will generate industrial waste gas containing volatile organic compounds (VOCs), harmful air pollutants (HAPs), and odorous gases during the production process. If these pollutants are discharged directly without treatment, they will not only pollute the environment, but may also cause photochemical smog, ozone … Read more

Why is Flue Gas Desulfurization Technology Needed? During industrial combustion processes, whether in coal-fired boilers, cement kilns, or steel sintering systems, large amounts of sulfur-containing flue gas are inevitably produced, with sulfur dioxide (SO₂) being the most significant pollutant. After being released into the atmosphere, this gas reacts with moisture and oxygen in the air … Read more

Industrial waste heat refers to the waste heat energy generated during industrial production processes. Traditionally, this waste heat is released into the atmosphere through cooling devices, resulting in significant energy waste and environmental pollution. Therefore, the recovery and utilization of industrial waste heat has crucial economic and environmental significance. What is Industrial Waste Heat Recovery? … Read more

The cement industry is a foundational industry for any nation, and the nitrogen oxides (NOx) emitted during the cement production process constitute one of the primary factors contributing to environmental pollution. Why are Cement Kilns a Major Source of NOx Emissions? Fuel Characteristics The fuels used in cement production include coal, coke, waste materials, and … Read more

As one of the core pieces of equipment in the petrochemical industry, heat exchangers play a crucial role in heat transfer throughout refinery processes. Heat exchangers in refinery can function not only as heaters or coolers on their own, but also as essential components in the production of many chemical products. From an energy efficiency … Read more

Many harmful gases are generated during petrochemical and natural gas processing, among them sulfur-containing gases (such as H₂S) that cause serious air pollution and require treatment with sulfur recovery devices. In the sulfur recovery process, the burner is a core piece of equipment; its function is to convert acidic gases such as hydrogen sulfide into … Read more

Industrial burners are used in many industrial furnaces and are important heating devices that play a core role in many industrial production processes. Industrial burners are responsible for generating and controlling the various temperatures required for the operation of industrial furnaces, and their performance directly affects the operating efficiency of the entire system. Industrial burners … Read more

In recent years, as environmental regulations have tightened, emission standards for industrial boilers, kilns, and other equipment have also been increased, making low-NOx burners a crucial choice for corporate energy conservation and emission reduction. However, many people have a limited understanding of the emission reduction principles of low-NOx burners and their advantages over traditional burners. As experts … Read more
