STUDY ON CO_2 HYDRATE SLURRY PRODUCTION WITH ADDITIVES

摘要

In this study, a CO_2 hydrate slurry production system is established. The effect of additives SDS and TBAB on CO_2 hydrate slurry production and antiagglomeration are investigated. The morphology of CO_2 hydrate slurry observed. The results show that non-full liquid system is favourable for hydrates production with lower induction time and overpressure compared with full liquid system. SDS can promote hydration slurry production but it shows less effect on reducing hydrate slurry agglomerantion. While with the concentration of 0.25%, TBAB shows good performance for hydrate formation and antiagglomeration.
