IN 1976, George Box opined: “All models are wrong, some are useful.” How do we assure that a model is not sufficiently wrong that it is useful? A useful model is one that adequately predicts the results under the conditions and scale required for design or a process simulation. Most models of course are not derived at design scale. We are inevitably working outside the envelope of model derivation. So how do we build confidence that the extrapolation is adequately correct that the results may be trusted?

Process simulation software has become almost universal in the chemical engineering sector, and many students have access to at least one commercial process modelling software package at university. Industry professionals are increasingly using software to model their processes. However, dynamic modelling (that accounts for time-dependent changes in the state of a system) is still, for many, an unknown quantity within the chemical engineering sector, and is more expensive than steady-state modelling.

As a follow up to the feature “Energy Saviours” (issue 927, September 2018), this article explores further opportunities for energy saving relating to upstream oil and gas unit operations and equipment. As I said in the previous article, I believe chemical engineers have a hugely significant role to play in decarbonising the environment and reducing other harmful gaseous emissions. I remain to be convinced that CCS is required to meet the UK’s carbon reduction goals. My preferences for emissions reduction are: use less energy; if we need energy it should be from renewables; if we have to burn something, make it hydrogen; use low carbon synthesis routes, eg steel and cement; and for difficult carbon emissions, offset them with land use.

IT’S no secret that each year, eye-watering amounts of food go to waste. With that as a starting point, in 2014 we formed TerraServ, a South African company based in the town of Secunda. The aim was fairly simple, to develop processing of waste sugary foodstuffs – discarded mostly for ‘cosmetic’ reasons – into bio-ethanol based products such as hand sanitisers and cleaning products, under the EcoEth brand.
