In the LNG process, hydrocarbon gases (C1-C4) need to be cooled down in a large multi tube heat exchanger with several passes.To ensure an efficient heat transfer, the gas-liquid mixture needs to be homogeneously dispersed over the whole pipe cross section so that each pipe of the heat exchanger gets the same amount of gas and liquid.
A static mixer maintains the dispersion in the conical pipe, changing from feed pipe to the inlet of the heat exchanger.
This effective mixing and dispersion in the conical pipe is effected in a patented conical SMV Sulzer mixer.

Customer advantages 

• Efficient mixing of gases with liquids
• Reduction of the heat exchanger size
• Mal-distribution in the heat exchanger is avoided
• Stable flow pattern over the conical section is maintained
