The relationship between stress of plate-fin structures and emergency stop operation process in LNG heat exchanger

For insuring the safe operation of LNG heat exchanger in Emergency Stop Operation Process (ESOP), a numerical method is proposed to investigate stress Plate-Fin Structures (PFS) that. The relationship between PFS and ESOP analyzed exchanger. results will be obtained that maximum equivalent greater at initial stage than last when HMR pressure more 5 MPa. increases with equilibrium temperature 180 K reaches peak value ESOP. larger other pressure. When difference ESOP, influence obvious for PFS. In should controlled within 240 K, respectively.
