Desulfurization device

Our desulfurization devices use different methods and equipment for different processes. According to the desulfurization method, they can be divided into seven categories, including intrinsically safe dry desulfurization, wet desulfurization (wet desulfurization includes amine desulfurization and complex iron desulfurization), R&D-based improved wet desulfurization for high-sulfur gas wells, R&D-based improved wet desulfurization for composite desulfurization of small and medium-sized sites, and direct oxidation desulfurization.

Technology introduction:

Dry desulfurization is a process in which H2S gas first enters the crystalline water film of iron oxide and is converted into hydrogen sulfide ions and S2- ions. These two ions then further react with iron oxide to form iron sulfide and ferrous sulfide. This method is suitable for low sulfur content and low flow conditions.

Amine desulfurization is a process that utilizes the weak alkalinity of alcohol amines to make countercurrent contact with natural gas in the absorption tower, thereby absorbing H2S from natural gas and achieving the goal of removal. Conventional MDEA method (methyldiethanolamine) and MDEA (methyldiethanolamine) are used + DEA (Diethanolamine) . 

Complex iron desulfurization technology is a wet oxidation method using complex iron as a catalyst to remove hydrogen sulfide. This method directly converts H2S into sulfur without reaction equilibrium restrictions, with a conversion rate of 99.99+%. The treated H2S concentration is less than 5mg/Nm3. It has the characteristics of renewable catalysts, meeting reaction conditions at normal pressure and room temperature, non-toxic iron-based catalysts, fast reaction speed, short process flow, high desulfurization efficiency, low energy consumption, compact structure, small footprint, and basically no three waste emissions and pollution in the production process.

Suitable for wellhead gas desulfurization with H2S ≥ 10000mg/m3, greatly reducing comprehensive treatment costs. The agent is formulated independently, the equipment is designed and manufactured independently, and the process package is complete. 

The composite desulfurization process for small and medium-sized stations uses independently developed specialized desulfurization agents to undergo irreversible chemical reactions with H2S, thereby achieving the goal of removing H2S from natural gas. The generated desulfurization products are all water-soluble liquids with high safety, and the recovery and treatment of waste desulfurizers are easy. They can be used as compost and do not belong to solid waste, greatly saving the cost of waste desulfurizer treatment. This process is suitable for natural gas treatment conditions with H2S ≤ 1000mg/m3.

Super Claus is a type of desulfurization method that directly converts H2S in natural gas into elemental sulfur under aerobic conditions by selecting the oxidation catalyst bed and activation temperature point. This method is suitable for natural gas desulfurization in situations where the latent sulfur content is ≤ 50t/d and can provide medium pressure steam. 

Our advantages:

Our desulfurization technology is in a leading position in the industry, with multiple advantages such as high efficiency, environmental protection and economy. The desulfurization efficiency is as high as over 99%, far exceeding the industry average. Secondly, the process design fully considers environmental protection requirements. The by-products generated during the desulfurization process can be recycled, reducing secondary pollution to the environment, which is in line with the concept of green and sustainable development. In addition, our technology also has the characteristics of low operating cost, long equipment life and simple operation, saving customers a lot of maintenance and operating costs.
