The client reported that the flash vessels in the digestion facility were receiving significant internal erosion around the flash vessel inlet nozzle, the inlet riser, witches hat and cone shell. The client suspected that the high wear is due to a number of operating factors, with the most significant being associated with the flashing of the digestion slurry. With past investigations and mitigations to minimise wear in mind, Carnac reviewed and provided recommendations on how these nozzles may be modified to potentially reduce internal vessel wear and optimise flows, focusing on the difference between the smaller nozzles on the lead flash vessels, versus the downstream Flash Vessels. Carnac approached this work with focus on the development of FFDS, a hydraulic modelling software that Carnac has acquired. Plant simulation software SysCAD was also used. While the scope of work initially focussed on a hydraulics solutions, Carnac was able to identify a lower-cost process solution.
