A breath of fresh air (Day 351)

Chemical engineering has to be one of the most creative of all professions. We look for opportunities in everything, even in the air that surrounds us.

In the early 20th century, Carl von Linde pioneered the process of air separation, splitting air into its pure components. He developed a technique to obtain pure oxygen and nitrogen by means of fractional distillation from liquefied air.

Since then, air separation has been applied to many products we use every day. In February, I attended an IChemE event at the University of Surrey. During the event, I met Jama Salimov, an Advanced Process Control Engineer at Air Products. Jama was keen to shine a light on his work in air separation and ensure that we all understand its many applications.

Air separation typically separates air into its primary components – nitrogen and oxygen. However, it can also isolate some of the more rare parts of the air such as argon.

The products of air separation have a wide variety of uses in our everyday lives. Many of us use them without even realising it – and Jama was keen to tell me all about them.

Many consumers find the energy markets frustrating and, whichever country you live in, it is likely that the choice of where you get your gas or electricity from will be limited, even if provided by the private sector.

The most ubiquitous, successful and competitive model we currently have for ‘buying’ energy is the petrol station. The first makeshift ‘filling station’ appeared in 1888 in Germany. The first purpose-built ‘gas station’ was constructed in the USA in 1905.

Today, there’s in excess of a million petrol stations dotted around the world, and it is infrastructure on this scale, along with public acceptance, that are important enablers to the widespread adoption of any technology, especially energy.
