What caught our eye - three key stories (week 19, 2024)

Here are three stories that we found particularly interesting this week and why. We also give our lateral thought on each one.

The refinery of the future

Refineries are important parts of the current industrial complex as they process crude oil into useful products such as fuels and feedstocks for various important chemical processes.

Of course we know that burning fossil fuels is a major contributor to man-made greenhouse gas emissions so cutting down our use of them is a positive for the environment. However, what about all of those useful chemical feedstocks that ultimately produce useful end products including plastics for us? Do we have to give those up too?

Paul Martin, a well regarded chemical process development expert, argues in a LinkedIn article that the refinery of the future will be able to still produce those useful products without the need to produce the fuels. It will require a few changes.

Firstly Paul highlights one of the big burners of fuel are the refineries themselves that need to create heat to run their various processes. Electricity can replace this. Heat pumps can effectively reuse waste heat very efficiently and in fact it is only not done more now due to the cheapness of fuels and cooling water currently, as Paul points out. In the future as externalities such as pollution get priced into fuels efficient processes will likely become the norm. Where higher temperatures are required, electric heating, including plasma arcs, can be used.

Secondly, residual 'waste products' from refining that are often burned as fuels too, need to be reconsidered and even transformed further into useful products, even if that means using inefficient processes - as Paul argues, that is still better than burning plus capturing the CO2!

Will it mean petrochemicals and plastics will be more expensive in a post-decarbonised world? Probably with the higher processing costs offsetting the cheaper feedstocks, but as Paul points out "... that's good expensive [as it] means we'll be motivated to conserve and recycle them better."
