In the refining and chemical industry, natural gas purification, coal chemical industry, and other industries, a large amount of tail gas will be generated during the production process of sulfur recovery. These exhaust gases are mainly nitrogen, and also contain a small number of flammable components such as hydrogen sulfide, hydrogen, and sulfur. In the … Read more

In August 2021, Luoyang Ruichang Environmental Engineering Co., Ltd. contracted the burner of the 40,000-ton/year sulfur recovery unit for the super-large pulverized coal gasification demonstration project of Shandong Runyin Biochemical Co., Ltd. Technical Features The raw gas of the sulfur recovery unit comes from the low-temperature methanol washing of this project, the low-temperature methanol washing … Read more

The industrial waste heat resources are rich, and the waste heat resources account for about 17% to 67% of the total fuel consumption, of which the recovery rate is 60%. Industrial waste heat recovery and utilization are also considered a “new energy”. The development of industrial waste heat recovery and utilization technology reduces the thermal … Read more

Styrene Unit Needs Retrofit to Reduce NOx Emissions In September 2020, the Order No.1 of the General Manager of China Petrochemical Corporation was officially issued, and the document put forward higher requirements for the NOx emission index of the heating furnace. The NOx emission concentration of key enterprises should be controlled at 60mg/m³, and the … Read more

Ruichang REGLASS industrial white smoke phase change coagulation treatment technology is a new type of exhaust gas treatment technology that effectively eliminates the “white smoke” emission of industrial waste gas. In the flue gas elimination process, the flue gas water vapor is condensed to form a condensate, which can absorb most of the solid particles, … Read more

VOC gas is a volatile organic compound that is harmful to the human body. This gas comes from the waste gas generated in the industrial production process. In order to reduce the harm of this kind of industrial waste gas to the atmospheric environment, we need to adopt certain methods to deal with it. The … Read more

What are the Effects of Sulfur Recovery Unit Failure? The failure of the sulfur recovery unit will cause the elemental sulfur to not be recovered normally, resulting in a sharp increase in SO2 emissions and causing environmental pollution.The sulfur recovery unit is the main recovery device of SRU plant and chemical plant, used to recover … Read more

Flue gas desulfurization technology can generally be divided into three categories: dry method, semi-dry method and wet method. Dry method includes: SDS, CFB, SDA, NID and dense coherent method, etc. Wet flue gas desulfurization technology is relatively mature, including lime gypsum method, sodium alkali method, magnesium method, zinc oxide method and so on. Circulating fluidized … Read more
