Electro-Dynamic Desalter


Installation of new desalting technology Electro-Dynamic Desalter (EDD) at Holly WX Refinery, Utah 2007

With plot space non existent in the crude unit we had to be creative. The solution was simple “go up”. We built a raised structure above the preheat crude train of exchangers to support the new EDD. The new technology is an AC/DC combination with alternating AC plates and DC plates. Power feed is single phase 460 AC to a transformer that controls the alternating currents. The installation is to add additional desalting capacity thus maximizing crude throughput.
