Title:
ETHYLENE GLYCOL PREGNANT SOLUTION REGENERATION DEHYDRATION SYSTEM AND METHOD IN DEEP SEA NATURAL GAS EXTRACTION PROCESS
Document Type and Number:
WIPO Patent Application WO/2022/062316
Kind Code:
A1
Abstract:
An ethylene glycol pregnant solution regeneration dehydration system and method in a deep sea natural gas extraction process. The dehydration system comprises an ethylene glycol-rich tank (G-1) storing an ethylene glycol-rich solution from an upstream pretreatment system, a pregnant solution transport pump (P-1), a heat exchanger (E-1), a regeneration tower (T-1), a condenser (E-2), a condensate tank (G-2), a vertical thermosyphon reboiler (E-3), a barren solution transport pump (P-2), a condensate pump (P-3), and a vacuum pump (P-4).
