Aqua-Pure is a licensed user of OLI software, an aqueous (electrolyte) chemistry model. Electrolyte chemistry is particularly complex and challenging to understand and predict, especially for real industrial systems containing many components and operating over broad ranges of temperature, pressure, and concentration. Simplified aqueous modeling and computational approaches using approximation are usually useless, or worse yet, dangerously misleading, when applied to real world applications. Aqueous systems often behave in complex and counter-intuitive ways, introducing great risk into plant design and operation if not properly understood and accounted for. On the other hand, reliable electrolyte models make possible tremendous insight, process alternatives, and efficiencies in plant design, trouble-shooting, and optimization. At Aqua-Pure we incorporate the OLI model into our design process, ensuring our systems are well suited for the specific application. (www.olisystems.com)
