The COVID-19 pandemic can be viewed as one of the most challenging periods in the history of the oil and gas sector. Refineries worldwide faced difficult times operating at their turndown capacities or even temporarily shut down units at the refinery.

Flexibility in catalyst technology for improved bottoms upgrading

Bottoms product from fluidized catalytic cracking (FCC) is typically one of the least valuable products from a refinery.

Over the past two decades, annual global demands for refined products and basic petrochemicals have increased by approximately 1.3% and 3.5%, respectively.

Heat Transfer

Cut emissions and fuel while increasing capacity in fired heaters
Poth, J., IGS

According to a recent digital refining article,1 fired heaters are responsible for an estimated 400 MMtpy–500 MMtpy of CO2, with at least 73% of average refinery CO2 emissions coming from combustion.
