Title:
MULTI-PRODUCT LIQUEFACTION METHOD AND SYSTEM
Document Type and Number:
Japanese Patent JP2019052839
Kind Code:
A
Abstract:
To provide a hydrocarbon liquefaction plant and process capable of liquefying multiple different feed streams with minimal product flash.SOLUTION: A liquefaction system 160 is capable of sequentially or simultaneously liquefying multiple feed streams 100 of hydrocarbons having different normal bubble points with minimal flash. The liquefying heat exchanger 150 has separate circuits for handling multiple feed streams. The feed stream with the lowest normal boiling point is sub-cooled sufficiently to suppress most of the flash. Feed streams with relatively high normal boiling points are cooled to substantially the same temperature, then blended with bypass streams 102 to maintain each product near its normal bubble point. The system can also liquefy one stream at a time by using a dedicated circuit or by allocating the same feed to multiple circuits.SELECTED DRAWING: Figure 1
