Heat Transfer Problems in Liquefied Natural Gas Plants
The design of any cryogenic process, whether it be liquefaction of natural gas, helium or hydrogen purification, air separation, or related units, depends on the efficient transfer of heat. The latter becomes even more significant when subatmospheric temperatures are involved and the refrigeration is generated within the process scheme itself, such as in Joule—Thomson and turboexpansion cycles. In the case of externally refrigerated plants, poor exchanger design usually results in lower capacity or off-specification products.
