Experimental study by onlinemeasurement of the precipitation of nickel hydroxide: Effects of operating conditions
摘要
Abstract
The objective of this work is using the online measurementmethod to study the process of precipitation of nickel hydroxide in a single-feed semi-batch stirred reactor with an internal diameter of D = 240 mm. The effects of impeller speed
impeller type
impeller diameter and feed location on the mean particle size d
43
and particle size distribution (PSD) were investigated. d
43
and PSD were measured online using a Malvern Insitec Liquid Process Sizer every 20 s. It was found that d
43
varied between 13 μm and 26 μm under different operating conditions
and it decreased with increasing impeller diameter.When feeding at the off-bottomdistance of D/2 under lower impeller speeds
d
43
was significantly smaller than that at D/3. PSDs were slightly influenced by operating conditions.
