SDSµ-Scrubber- Methanol Yield Improvement

Based on SRS technology the SDSµ-Scrubber combines a highly efficient scrubbing performance and effective gas-liquid separation in both co-current and counter-current solutions

USING HIGHLY EFFICIENT RPS TECHNOLOGY 

The Methanol production process is already very mature, but within this  process, traditional separation technologies are not fully effective. Methanol product will be lost, as the entrained liquid in the gas is taken to the downstream.dsf

This will result in a lower methanol yield, more side reactions, lower catalyst lifespan and reduction of  the stability of the entire methanol plant. RPS Technology can very efficiently solve these problems.

SOLUTIONS TO PROBLEMS IN THE METHANOL PRODUCTION INDUSTRY:

  • Conventional methanol separators usually use gravity separation, wire mesh or windpack internals to de- mist. However, the separation effect is not ideal, resulting in a large amount of methanol entrained downstream in the form of droplets, which reduces methanol yields and exacerbates the side reactions. 
  • Non-ideal separation effect of the oil-gas separator after the compressor, causing oil pollution within the synthesis reactor. This can cause catalyst poisoning, and reducing the lifespan of the catalyst.
  • The exhaust gas carries a large amount of methanol (droplet and gas phase) into the fuel system, which will will be burned and wasted. This is valuable methanol product that could have been recovered.
