Coal gas organic sulfur fine removal technology
Because blast furnace gas contains organic sulfur, H2S and other impurities, if blast furnace gas is used as fuel, the SO2 in the flue gas does not meet emission standards. There are two main measures to reduce emissions: blast furnace gas desulfurization or exhaust flue gas desulfurization.
Food grade CO2 purified
Food CO₂ purified Adopting the internationally recognized new catalytic oxidation purification technology, the catalytic purification tower adopts a new type of internal cooling device, so that the bed temperature distribution is in the appropriate reaction zone, normal production heat balance, reducing the use of electric furnaces and extending the service life of the catalyst.
VOC tail gas disposal
Tank and loading waste gas, tail gas containing VOC in petrochemical and chemical industries. It is first condensed using the PSA method and then disposed of by condensation, which meets environmental drainage requirements and allows the recycling of some organic matter. Installation scale: 100-3000nm3/h
Unit desalting and demineralization equipment and special resin
This unit is an exclusive block device for the ionic liquid flue gas desulfurization project and is the key equipment for the ionic liquid desulfurization process, the desalting device is designed to remove harmful impurities such as sulfuric acid roots, chlorine and fluorine in the ionic liquid; Sodium Removal Device are used to remove harmful cationic impurities such as sodium in ionic liquid.
Hydrogen production by coal gasification
Producing technical hydrogen from coal is a good option for large-scale hydrogen production or in the absence of other suitable raw materials. From raw coal, high purity hydrogen is produced through gasification, conversion, purification, PSA, etc. units.
Hydrogen purification technology by pressure swing adsorption
The Pressure Swing Adsorption Nitrogen Generator (abbreviated as PSA Nitrogen Generator) is a nitrogen generator designed and manufactured on the principle of gas separation with PSA technology. Usually two adsorbers are used, the automatic control system strictly controls the time sequence according to a certain programmable program, alternately carries out pressure adsorption and pressure reduction regeneration to carry out the separation of nitrogen and oxygen and obtain nitrogen of the required purity.
CO2 removal by pressure swing adsorption
PSA CO separation technology is widely used in synthetic ammonia, methanol, alkali and industrial CO2 separation decarbonization plants, as well as CO2-containing tail gas recovery plants, due to the high degree of automation, convenient control of removal precision, low energy consumption and a wide range of applications.
Flue gas denitrification SCR、SNC
Technology Description Technology Description There are two main denitration methods (1) Selective Catalytic Reduction (SCR) technology and (2) Selective Non-Capital Reduction (SNCR) technology.
Oxygen production by pressure swing adsorption
Since 1994, our company began to work on the development and application of oxygen production technology using the air separation method PSA (VPSA-O2), and in May 1995, we industrialized and built an oxygen production plant using the PSA method. The oxygen plant built by the company has excellent performance, low production costs, and no environmental pollution. The company is a manufacturer of patented technologies, as well as the production of proprietary LIX lithium oxygen adsorbent and large bore control valve.
MEA-MDEA-NHD Desulfurization Technology
A typical amine desulfurization and decarbonization process consists of four parts: absorption, flash evaporation, heat exchange and regeneration (stripping).
absorbent
An adsorbent is a solid substance that can effectively adsorb certain components from gases or liquids. Adsorbents usually have the following characteristics: large specific surface area, suitable pore structure and surface structure
Hydrogen production by splitting methanol
This process is based on the convenient source of methanol and desalting water as raw materials, at a temperature of 220-280°C, a special catalyst is catalyzed into converted gas containing hydrogen and carbon dioxide, the principle of which is as follows: Main reaction: CH3OH=CO+2H2 +90.7 kJ/mol CO+H2O=CO2+H2 -41.2 kJ/mol General reaction: CH3OH+H2O=CO2+3H2 +49.5 kJ/mol Auxiliary reaction: 2CH3OH=CH3OCH3+H2O -24.9 kJ/mol CO+3H2=CH4+H2O -+206.3 kJ/mol
Coke gas purification technology
After recycling in the chemical industry, coke oven gas retains impurities of sulfur, tar, naphthalene and benzene. When producing electricity from coke oven gas and CCPP, compressing coke oven gas, heating coke oven gas, cutting coke oven gas and producing chemical products from coke oven gas, production problems arise, such as clogging of nozzles, corrosion, excess SO2 emissions after combustion, carbon deposits and poisoning of catalysts, so deep purification of coke oven gas from harmful impurities is necessary.
Wet CO2 removal technology
Wet method decarbonization technology is a low energy consumption technology that is widely used to remove CO2 and H2S from synthetic ammonia, methanol feed gas, refinery gas, urban coal gas and natural gas.
Oxygen purification and utilization
In the production and combustion process of lithium batteries, residual high-temperature oxygen-rich flue gas is generated, in the traditional method, usually after environmental treatment, it is directly discharged into the atmosphere as exhaust gas, which leads to large oxygen consumption in the production process, high energy consumption, thereby increasing the production cost of lithium batteries.
Ethylene tail gas recovery
In recent years, with the increase in people's awareness of environmental protection, the improvement of environmental requirements for petrochemical plants in China and around the world, and the recovery and reuse of waste to reduce production costs, considering the higher economic efficiency for enterprises, the exhaust gas recovery technology of ethylene and acrylic plants has great social and economic benefits.
