Dr Shahidah Mohd Shariff is an expert in process technology specialising in purification and separation techniques. She has demonstrated a strong technical vision and prowess in using science, engineering, and innovation to advocate growth. Her thought and idea, by design, in building the capability of Petronas Research is highly commendable. Her involvement is significant in driving research product to commercialisation in Petronas. Her achievement is mainly in process engineering, utilising novel chemistry and engineering concepts to address operational reliability and risk reduction. Under her stewardship, two of her work has reached commercialisation with a total economic contribution of RM1.1mil. The first is the Melaka Group 3 (MGS) base oil production plant, the first in the world that uses atmospheric bottom that otherwise would be exported at a fraction of its value. The efforts were 100% by local researchers, which have generated vast operational knowledge and trade secrets. Until today, the team supports the operation of the plant without the need for input from the process licensor. Her second work is the world’s first iconic based mercury removal system commercialised in a record time of seven years. It was engineered as a ‘drop-in’ solution to the existing plants, which required a short turnover. These projects have won many international recognitions. Dr Shahidah also spearheaded sustainability engineering efforts in Petronas. Four technologies, designed based on sustainable engineering principles, have won six awards internationally with 14 patent families. She was elected as Women of the Year 2016 by premier publication Oil & Gas Resource and, Fellow of the American Chemical Society Industrial & Engineering Chemistry Division International in 2018, the first Malaysian to receive the honour. She also received Honorary Degree in Engineering with Distinction in 2018 from Queen’s University of Belfast, acknowledging her contribution to sustainable engineering.
