Abstract
Industrial agitator or mixer configurations and associated applications present the design engineer with a unique set of challenges. This was especially true when a major chemical company required an agitator for a large multistaged column. A traditional approach to mixer design, in this case, would attract high vessel and agitator cost due to the nature of the machine design and the associated mounting/operational loads. This paper reviews the design constraints and problems, along with the solutions developed to provide the end user with equipment that is easily maintainable, and had an attractive capital cost. In particular, it compares the design solutions with the traditional design approaches, and discusses how finite element modeling was used to verify operational limitation due to natural frequency constraints. The paper concentrates on the key component associated with the mixer shaft, and specifically excludes discussion relating to the design and feature requirements relative to gearbox selection.
