Equipment Introduction: The low-temperature methanol scrubber is a gas purification device widely used in the coal chemical industry, syngas purification, natural gas processing, and other fields. Its primary function is to use low-temperature methanol (typically at -40°C to -70°C) as an absorbent to remove acidic gases (such as H₂S and CO₂), organic sulfur compounds (such as COS), and other impurities from syngas or natural gas, thereby improving gas purity. Basic Parameters and Structural Features of the Equipment: Scrubber Body: Made of low-temperature-resistant materials (such as low-temperature stainless steel or alloy steel). Circulation Pump: Used to transport low-temperature methanol absorption liquid, ensuring liquid circulation within the tower and stable absorption efficiency.Heat Exchange System: Includes a cooler (to lower the methanol temperature) and a regeneration heater (to desorb acidic gases).Separation System: Facilitates gas-liquid separation, ensuring effective separation of purified gas and methanol solution rich in acidic gases. Control System: Enables automatic regulation of temperature, pressure, flow, and gas composition to ensure stable process operation. Main Material:09MnNiDR The equipment structure design and material selection can be optimized according to the specific needs of users. Application Range: Coal-to-Gas / Coal Chemical Industry: Used for gas purification in coal-to-hydrogen, coal-to-methanol, coal-to-natural gas, and similar processes. Natural Gas Processing: Removes CO₂ and H₂S from natural gas to improve gas quality. Oil Refining and Petrochemical Industry: Purifies sulfur-containing gases, such as refinery gas and coke oven gas. Tower parameters: 1. Tower diameter: usually between 1.5 meters and 6 meters, depending on the gas volume and operating conditions. 2. Tower height: usually between 20 meters and 60 meters, depending on process requirements. 3. Material: commonly used stainless steel or carbon steel lining anti-corrosion materials to cope with the corrosiveness of methanol 4. Gas parameters Inlet flow rate: usually between 5000 Nm³/h and 50000 Nm³/h, depending on the production scale. 5. Inlet temperature: close to ambient temperature, about 20°C to 40°C. Inlet pressure: 2.0 MPa to 6.0 MPa. 

Low temperature methanol scrubber

The dedicated sensor adopts the principle of thermal conduction analysis to detect the gas flow direction. When the gas flow direction is abnormal, the sensor outputs corresponding signals. When the signals reach the limit value, the self-controlled actuator will be triggered to actuate, achieving the purpose of protecting the equipment. It is applicable to scenarios where there are requirements for gas flow direction. Technical indicators: SensitivityWhen the environmental temperature is within the range of (10~35)℃, and the gas flow density in the pipeline in the direction of flow is ≤ 2.3mg/cm2·s, the sensor's load resistance should be ≥ 1000Ω, and its sensitivity should not be less than 30mV·cm2·s/mg. When the sensor's load resistance is ≥ 250Ω, its sensitivity shall not be less than 23 mV·cm2·s/mg.Output voltageWhen the gas flow density in the pipeline that is prohibited from flowing changes stepwise from 0 to (0.45 ± 0.20) g/cm2·s, the average increase rate of the sensor's output voltage is not less than 60 mV/s.Supply voltage（12.0±0.1）VDCFunctional highlight: This product responds very quickly. The product possesses the ability of corrosion resistance and strong impact resistance.
