Multi-phase flow instabilities in liquefied natural gas cryogenic heat exchangers affect flow distributions in the system adversely. This consequently has negative impact on the energy consumption of the liquefied natural gas cryogenic heat exchangers. What softwares can be applied to determine the flow in different stacking layers caused by difference in channel dimensions, flow length and fluid properties like densities and viscosity variation?
HYSYS integrated simulation software and ASPEN PLUS software has been tested and proven and has stood the test of time for process plant operation and systems design. Advances has been made in the newest versions to make them more suitable for cryogenic operations where temperature is expected to be as low as -4 C and de-icing agents such as glycol injected to maintain process material states.
