Decarbonisation Technology - February 2022 Issue

Decarbonisation through innovation

need to be kept to less than two degrees Celsius (°C) above pre-industrial levels. The conference resulted in the “Paris Agreement,” adopted by all UNFCCC parties, which was a first legally binding global climate agreement of its kind. The role of electric heat exchangers Electrification of industrial processes is one of the key strategic pillars for addressing climate change concerns. Many industries use gas-fired heaters, but we are seeing a gradual shift to large electric heat exchangers. One challenge of this change is that electric heaters need to be able to accommodate the larger wattage and amperage requirements of these processes, which must be balanced with another challenge – control. Adequate control of the heater is needed to ensure that processes can be performed safely. Some heat exchanger designs have dead zones where hot spots can occur, which exacerbates the coking process, leading to fouling and the need for further maintenance. Continuous Helical Flow Technology offers ultra-high heat transfer rates with minimal fluid bypass, eliminating these dead zones and contributing to a smaller footprint. When selecting an electric heater manufacturer in the process of electrifying your processes, it is crucial to ensure the company can provide safe and reliable heating solutions that contribute towards a greener footprint. With over a century of experience developing, testing and validating electric heat exchanger designs, Watlow’s HELIMAX™ heat exchanger uses these innovations to improve performance, heater life and minimise carbon footprint. Although progress is being made towards decarbonising energy processing, there is still a long way to go. Switching to electric heat exchanges with advanced fluid dynamics, Continuous Helical Flow Technology and higher watt densities can aid the journey of electrification and decarbonisation much more efficiently.

Decarbonisation, electrification and the case for modern electric process heaters Companies in the oil and gas industry are taking bold steps to reduce their carbon footprint. The overall strategy to tackle carbon emissions relies not only on alternative energy investment and increased efficiency, but also converting key industrial processes to electric. Here Volker Metzger, Applied Thermal Expert for Europe at industrial heating technology manufacturer Watlow, explores the role of electric heating technologies in decarbonising industry. about the scope and causes of climate change, governments and industry leaders are taking huge steps to meet climate change goals, especially with regards to decarbonisation. According to the We Mean Business Coalition, over 700 companies have made far-reaching climate commitments, including many big players in the oil and gas industry. The pressure to electrify Though there are still passionate debates What is striking about the pressure to address climate change is that it does not come from one segment of the population, or from one international agreement. This means that even if a driver for change such as The Paris Agreement were to disappear, there would still be significant pressure to decarbonise and thus larger capital investments in electrification and decarbonisation are still completely justified. The Paris Agreement The event that caused many energy companies to consider decarbonisation strategies more seriously was the 2015 Paris Climate Conference, organised by the United Nations Framework Convention on Climate Change (UNFCCC). This led to a broad consensus about climate change and what needed to be done to combat it. The UNFCCC parties agreed that, to avoid the most catastrophic effects of climate change, the increase in global average temperature would
