Biogas — produced from anaerobic digestion of organic matter — contains a mixture of gases, with methane and carbon dioxide as the predominant components. To use biogas as a fuel source, purification of the gas is typically needed to remove CO2 and other contaminants to reach high methane concentrations. Traditional separation methods are effective, but can be energy-intensive and produce chemical waste.

I remember first learning the fundamentals of process control in my undergraduate courses some years ago. Our professor taught the class with a passion for the subject while impressing upon us, his students, how important the subject would be for our future jobs. He was right. Since then, the worlds of process control and automation have advanced by leaps and bounds.

One of the aspects of my job that I really enjoy is keeping in touch with new and advanced technologies emerging from the chemical process industries (CPI) — an interest that traces back to my roots as an R&D engineer. Since products from the CPI are used in just about every facet of our lives, the technologies being developed and scaled up are as varied as the intended applications, and many have far-reaching implications.

Efforts to address global water scarcity have driven advancements in technologies for water conservation, re-use, and treatment. Among these, desalination of seawater is a well-established method to combat shortages, although it is known for being energy-intensive. In contrast, solar-powered evaporation offers a more energy-efficient alternative. However, the presence of salt in seawater reduces the evaporation rate, with studies indicating seawater evaporates about 8% slower than pure water.
