Alfa Laval PureSOx gives customers the option to scrub exhaust gas in closed loop, either by choosing a fully equipped[ds_preview] hybrid system or by installing a hybrid-ready system that can be upgraded for closed-loop operation later. With the launch of a modular new PureSOx water cleaning system (WCS), these possibilities become even more attractive. As before, the foundation of the PureSOx WCS is high-speed centrifugal separation. In the new modular system, the separator module can be combined with a flocculator or a membrane module for additional capacity. According to Alfa Laval, new features lower closed-loop operating costs and increase safety. Still more benefits are achieved through two new features. One is the ability to use either NaOH or non-hazardous Mg(OH)2 as the alkaline additive, the other is the option of using seawater rather than fresh water for replenishing the water system, which yields lower energy costs.
