Improvement design of blending process / Faiz Hakimi Sharulizam

Improvement design of blending process is a tweaking project on how the current used or available agitation systems in the industry is revamped and enhanced the mixing efficiency by changing the impeller type or design. In this project, a multistage impeller consists of merging design of two hydrofoil impeller is chosen as the substitute impeller for the existing one. The reasons are because these impellers are commonly found in many agitations system. Moreover, throughout the past research and simulation it has been proven that the proposed impeller design is superior in every aspect juxtapose to the one that currently appointed in the industry. Besides, a Pugh chart that comprise of comparison between three initially chosen impeller also has been constructed to further approved which design meets the necessary criteria to reinforce the blending process. Further studies details within this paper are gathered by using SolidWorks. The pictorial design and flow simulation of the proposed impeller has been compared to other two impeller that has been used in the industry and proved to be the best impeller design for multistage impeller and effective compared to the other two. Thus, the impeller has satisfied both project objectives which are to compare the proposed and current used multistage impeller and configure the best multistage impeller design. Analysis of the impeller also proved that the configuration able to improve 33% of the blending time by cutting down the excess 30 minutes for recirculation as it has more balanced flow and absence of unmixed zone which is the problem for the multistage impeller configuration used before. Therefore, by using this configuration for the multistage impeller is the best possible method recommended for Sumber Petroleum Cemerlang Sdn Bhd (SPC) to eliminate over blending time problem due to improper mixed of the lubricant.
