A Novel Approach for Transient Process Monitoring and Control Thomas McCracken

摘要

Researchers have recognized that monitoring of industrial processes for time variations is critical when optimizing transient unit operations (English et al. [1]). Transient flow behavior is typically found in multiphase flow systems where mixing or dispersion equipment is used to contact one phase with another. In the present study, a novel method was developed for monitoring and analyzing variations in two-phase flow. The process studied was a system of feed piping and proprietary spray nozzle combined to provide optimal spray for reactor feed injection. Using wavelet transform analysis of pressure fluctuations measured in the flow, a significant improvement in atomization efficiency was achieved by modifying and controlling the flow pattern in the feed piping.
