Which company is the best for cyclone separators used in gasification?
Thread Content
The raw gas coming out of the gasifier contains a large amount of fly ash, which is usually sent to a cyclone separator for gas-solid separation. If this separation is not effective, it can have a serious impact on subsequent processes. The process specifications generally require a separation efficiency of over 90%. Are there any plants in operation in China that can meet this requirement?
The cyclone separators designed by the Institute of Engineering Thermophysics of the Chinese Academy of Sciences have very reliable performance.
What are the operational performance metrics? Can the 98% separation efficiency promised by some equipment manufacturers be achieved?
Gasifiers designed by us are in use in Chiping, Shandong, Pingguo, Guangxi, and other places.
Could you give a brief overview of the equipment’s design parameters? Thank you
This technology is supposed to be quite mature by now, but there is still room for improvement in the detailed aspects of it. The reality is that what everyone does is more or less the same.
With detailed basic data, there are still many ways to design this. It’s just that many technical parties are unable to come up with this.

About 5 years ago, Nuowei Technology successfully solved the problem of blockage in the discharge of the coarse gas dust removal cyclone separators provided by a German company for a coal gasification project at a well-known domestic coal chemical company. Please download the drawings of the high-efficiency kinetic separator from the link “High-efficiency kinetic vane-type gas-liquid separation, multi-factor swirl parent-child separation, and high-efficiency gas-liquid-liquid three-phase separation technologies at NOVEL Company”... http://bbs.hcbbs.com/thread-1354813-1-1.html (Source: Haichuan Chemical Industry Forum) to obtain more technical information.
When designing cyclone separators, domestic technology providers often rely on charts or estimates to determine various parameters, resulting in design data that differs significantly from actual operational results, or even being incorrect. Whether the technical designers have access to a precise and reliable design platform determines the gap between the design data and the actual operational results. This is the consensus among industry experts. Furthermore, the owner should ask the technical designer to submit the calculation documents for their professional platform separator process, in order to indirectly assess the authenticity of their technical design capabilities. Currently, many design institutes outsource the design and manufacturing of dynamic separators to domestic and foreign companies that possess specialized separation technologies. However, these companies specializing in separation technologies must provide the design institutes with calculations related to their separator processes, so as to assess the authenticity of their technical design capabilities; this also serves as a reference document for tracing issues and identifying their origins in the future. Furthermore, I gave a relatively detailed introduction to cyclone separators at the Haichuan Chemical Industry Forum. Regarding the cyclone separators used for gas-solid separation, there are typically cyclone separators that comply with domestic standards (using large-diameter single cylinders), as well as multi-element cyclone parent-separator units that have been adopted internationally in recent years (featuring distributed cyclones with diameters of 50–100 mm installed inside a parent shell). Due to the **reduction in the fluid rotation radius**, the latter experiences a qualitative improvement in terms of gas-solid separation accuracy, operational flexibility, as well as operational stability and reliability. In recent years, domestic and international projects, especially those using foreign process packages, have involved gas-solid separation equipment of a similar type; in such cases, multi-factor cyclone mother-separator technology is generally required to reduce operational bottlenecks and technical risks. Please ask colleagues to look for the relevant technical information on the Haichuan Chemicals Forum.
If the distribution of fly ash particles in the off-gas from the furnace cannot be provided, is it then impossible to determine the various dimensions of the cyclone separator through calculation? Even when different coal types are fed into the same furnace, the distribution of fly ash varies; pilot tests do not necessarily yield accurate data on this distribution, and in most cases it is only an estimate. Are there no standardized products for cyclone separators? Is it necessary to have one cyclone for each operating condition?
