90,000 t/a LNG project —— completion of LNG cold box machinery
LNG cryogenic cold box is a heat exchange equipment used to realize heat exchange between raw natural gas and refrigerant. It has the characteristics of ultra-low temperature, high pressure, multi-flow and two-phase flow heat exchange, etc. It is difficult to design and manufacture, and has long relied on imports.
Confirmed by naked cooling commissioning and inspection, the LNG liquefaction separation cold box has good mechanical properties at low temperature, no leakage and irreversible deformation, and the effect in the project application fully meets the design expectations.
