Effect of Impeller Agitation on Preparation of Tetra-n-Butyl Ammonium Bromide Semiclathrate Hydrate Slurries

Table 3

The relative results of important factors for the preparation of TBAB hydrate slurries in various impellers. Herein, the boundary between “small” and “large” is defined at the value of 1.0 mm (particle diameter) and 1.0 W (required power). The indexes of “low” and “high” mean the value of <5% and >10%, respectively, and “middle” does the value between them.

Impeller	𝑛𝑟 (rpm)	Particle diameter	Aggregation frequency	Required power
2-BP	100	Large	High	Small
	300	Large	Low	Small
MB	100	Large	Middle	Small
	300	Small	Low	Large
RC	100	Small	High	Small
	300	Small	High	Small
Conceptual	300	Small	Low	Small
