Jonathan Alexander | Albemarle


Mr. Alexander is a Technology Implementation for Competitive Advantage (TICA) Improvement Engineer for Albemarle’s Aluminum Alkyl plant in Pasadena, TX. He has made improving process quality and optimizing the production process his main goal by utilizing statistical process control and other analytical tools.  Through the implementation of the NWA software packages, quality within Albemarle has been taken to a new level by reducing out of spec material, improving yields, and driving increases in the operators’ process knowledge and understanding.   Providing the operators with unique process analytical tools and training has exponentially increased their ability to troubleshoot and solve routine process problems.  The process of transforming the operators into engineers has exponentially increased Albemarle’s ability to implement improvements not only during day shifts, but also during nights and weekends.
