Mueller – PyroPure Multiple-Effects Stills
U.S. Design & Made
The Mueller PyroPure P6000 Series is Built to Last
Mueller PyroPure multiple-effect stills (MES) are the simplest, most reliable means of producing pyrogen-free water-for-injection (WFI) that meets all U.S. Pharmacopoeia requirements. The MES is designed with efficiency in mind. Because the system recovers the latent heat of vaporization occurring within its own process to heat feedwater and uses feedwater as its primary source of cooling, the MES is an energy and money-saving model of ingenuity. Due to the absence of moving parts, the PyroPure MES requires less maintenance and is much quieter than mechanical compression stills. Multiple-effect stills also lack the seal and associated oil supply required by mechanical compression stills; therefore, there is no danger of contamination due to seal breakdown associated with mechanical compression. The PyroPure MES is manufactured according to FDA current Good Manufacturing Practices (cGMPs) and ASME-BPE requirements.
Each PyroPure MES is designed to minimize operating costs associated with production of WFI by minimizing the required utility steam and coolant consumption. This is accomplished by utilizing sources of energy within the various process streams to preheat the feedwater and thus use the feedwater as a cooling source. Using the feedwater as a coolant source also reduces the utility steam consumed to elevate the temperature of the feedwater. The feedwater ultimately enters the tubes of the first effect evaporator where utility steam is applied to the shell to evaporate the feedwater. The resulting steam produced is then directed to the separation column where a tangential inlet produces centrifugal force that separates the entrained water droplets away from the pure steam. This pure steam is then used as the heating source for the subsequent effect.
