Cylindrical Desulfurizer

A cylindrical desulfurizer, also known as a columnar desulfurizer, is a type of sorbent material used to remove sulfur compounds from gas streams in industrial applications. The sorbent material is typically packed into a cylindrical vessel, and the gas stream is passed through the bed of sorbent material. The sulfur compounds in the gas react with the sorbent material to form solid sulfide or sulfate compounds that can be collected and disposed of.

Cylindrical desulfurizers are commonly used in the oil and gas industry, where they are used to remove sulfur compounds from natural gas and refinery gases. They are also used in biogas and landfill gas purification to remove sulfur compounds that can cause corrosion and other issues in gas pipelines and other infrastructure.

Cylindrical desulfurizers are typically made from materials such as activated carbon, metal oxides, or calcium-based compounds. The choice of sorbent material will depend on the specific application and the characteristics of the gas stream being treated.

The performance of a cylindrical desulfurizer depends on a number of factors, including the type of sorbent material used, the gas flow rate, the temperature and pressure of the gas stream, and the concentration of sulfur compounds in the gas.

Performance of cylindrical desulfurizer

Sulfur removal efficiency

This refers to the percentage of sulfur compounds removed from the gas stream by the desulfurizer. Higher removal efficiency is generally better, as it means that more sulfur compounds are being removed from the gas stream.

Sulfur capacity

This refers to the amount of sulfur compounds that can be adsorbed by the desulfurizer before it needs to be replaced or regenerated. A higher sulfur capacity is generally better, as it means that the desulfurizer can operate for longer periods of time before needing to be replaced.

Pressure drop

This refers to the reduction in gas pressure that occurs as the gas flows through the desulfurizer. Higher pressure drop can reduce the efficiency of the gas treatment system and increase operating costs.

Operating temperature

This refers to the temperature at which the desulfurizer operates. Higher temperatures can increase the rate of sulfur removal but may also reduce the lifetime of the desulfurizer.

Regeneration ability

Some desulfurizers can be regenerated, which means that the sulfur compounds can be removed from the sorbent material and the material can be reused. The ability to regenerate the sorbent material can reduce operating costs and improve the sustainability of the gas treatment system.

Cylindrical desulfurizer process

The desulfurization system adopts MSGF dry desulfurization process, fixed bed structure, the bed is covered with desulfurizer, the flue gas enters the bed from the bottom, and the air distribution is uniform through the porous and ventilated plate in the lower part, the flue gas passes through the desulfurizer material layer, and is catalyzed Convert SO2 into SO2, and be reacted and solidified into calcium sulfate solid (CaSO4). In the reactor, due to the presence of bed material, the desulfurizer can spread with a larger surface area, remove SO2 in the flue gas, and The dust in the flue gas is intercepted and adsorbed to purify the flue gas. The by-products generated in the reactor are regularly replaced as the desulfurization and denitrification efficiency decreases. Its main component is CaSO4, which is common solid waste and can be recycled as building materials.

The upper part of the device is the desulfurization agent inlet, and the lower part is the desulfurization agent discharge port. After the device has been running for a period of time, the desulfurizer in the lower part that is in contact with the flue gas will gradually become invalid, and the desulfurization efficiency will decrease. At this time, the discharge port can be opened and will fail. Part of the desulfurization agent is removed, and fresh desulfurization agent is installed on the upper part of the device to ensure desulfurization efficiency. The desulfurization effect can be adjusted according to the requirements of the contact time, and can achieve more than 80% removal. It is not sensitive to some short-term fluctuations in flue gas conditions, and is not very sensitive to flue gas temperature. It is suitable for almost all flue gas conditions.
