Hydroprocessing Catalyst Process Technologist

Curtis Bay, Maryland, United States

In process technology, I worked with Grace Hydroprocessing Catalyst plants located in North America to begin developing critical process metrics for Fixed and Ebullating Bed catalyst production. This work entailed review of in-plant historical operating data, matching to downstream process results, then developing parameter ranges and deviation plans for individual catalyst grades. The frame work that was started here has continued to evolve into a robust SPC process for all Hydroprocessing catalysts within Grace. In addition to the SPC documents, I also worked with manufacturing units on specific project assignments.- Process review and capability study for the treatment and disposal process for an ammoniated slurry byproduct.- Review of lab test methodology for catalyst product length including a Gage R&R. I also revised the testing methodology to reduce variation across operators for generating test samples.- Support engineer for new-to-location production of a hydroprocessing catalyst grade. This work involved guiding decision making from my prior experience of making the catalyst in a different operating unit.

Process Engineer For Alumina And Hydroprocessing Catalyst

Lake Charles, Louisiana

This was a solutions driven role that aimed to streamline and improve plant operations and yield for a 70MT Alumina plant and a 55MT Hydroprocessing Catalyst (HPC) plant.Key projects included:• Plant coordination and research for a new product deployment in Alumina. The project resulted in increased production over 20% while tightening product quality. This work required coordinating R&D initiatives with Operation requirements, Sales goals, and Capital investment. During the course of this project I developed and deployed the product beyond the plant in Lake Charles to other Grace sites worldwide.• Deriving accurate accounting of raw material variance and production volume between the two plants to minimize yield loss and solidify production reporting• In-depth analysis of re-milling within HPC to decrease warehouse storage of rework material and increase production output.
