Catalyst disposal - An environmentally sound solution
Of increasing concern to the petroleum industry is the environmentally safe disposal of spent hydrotreating catalyst. Past practices such as landfilling or partial extraction of certain metals are no longer considered acceptable in light of new or proposed regulations nor are these practices economical when factoring in future liability. The unique CRI-MET process for complete catalyst recycling is described whereby the metals and the alumina are completely dissolved by means of a high temperature, high pressure leach. Subsequent separation techniques remove each constituent as a saleable product, leaving no waste. Thus, the generator is relieved of potential liability. The CRI-MET process is environmentally superior, economically attractive and presents a real alternative to existing practices.
