Title:
AIR TEMPERATURE TYPE LIQUEFACTION NATURAL GAS VAPORIZER
Document Type and Number:
Japanese Patent JP2019178691
Kind Code:
A
Abstract:
To provide an air temperature type liquefaction natural gas vaporizer capable of restricting increasing of calory of natural gas flowing in a natural gas discharging line and further shortening a set stopping time for ice breaking processing.SOLUTION: An operation control part M is constituted such that an ice breaking processing for keeping a gasification stopped state until a set stopping time elapses for every time in which an operation time elapses a set operation time is executed in sequence for several LNG vaporizers K under different times. Each of natural gas supply valves 9 for opening or closing a natural gas supply passage 8 to guide a part of natural gas flowing in a natural gas discharging line 2 to an inlet header part of the LNG vaporizer is arranged, respectively. The operation control part M is constituted to perform natural gas flowing processing to keep opened states of the natural gas supply valves 9 for LNG vaporizers executing the ice breaking treatment during execution of the ice breaking processing.SELECTED DRAWING: Figure 2
