When a steam utility is unavailable, electric heat may be a safe sensible first choice option. Electric heaters have been used in off site tanks for bituminous products for many years. But recently, with the move to environmentally friendly processes, and zero emissions at point of use, Electric Vaporizers have been put into service for fluids such as NH3, CO2, SO2, SO3 etc. These can be supplied skidded with valves, pumps, controls and piping. These are now commonly found in power stations where NOx and SOx emission reduction systems are used.
