Unlock dewaxing performance with a selective dewaxing catalyst in fossil and renewable fuels service
To address various challenges, the authors’ company has developed a selective dewaxing catalyst suitable for fossil feeds, co-processing and 100% renewable services. This article details this novel technology.
How leading refineries achieve operational excellence
Although cost cutting provides short-term financial benefits, it does not improve anything operationally in a plant. The reality is that most companies have already pushed such programs to their practical limits. So, what is left? The alternative approach is improving performance through operational excellence. This article will unpack this approach with examples of how producers have benefitted from it.
