New environmental legislation has created an engineering challenge for heavy-duty diesel engines.CO2 and NOx emissions must fall below stricter standards; at the same time greater engine efficiency has resulted in a corresponding loss of exhaust gas temperature, leading to lower catalytic activity. This is particularly concerning when it comes to NOx emissions for Cold Start and Low Load Cycles, as there is a lot of thermal inertia in the aftertreatment system.

Companies in liquified natural gas (LNG) and other industries have been taking bold steps to reduce their carbon footprint. The overall strategy of these companies is to tackle carbon emissions not only through alternative energy investment and increased efficiency, but also through converting key industrial processes (like process heating) to electric (rather than fuel-fired). This paper explores pressures to electrify process heating, as well as the role that electric heat exchangers are playing, particularly in light of innovations in the design of these heaters.
