Title: Inventor Chandrakant Tiwari: Innovations in Water Treatment Technology
Introduction
Chandrakant Tiwari, an inventive mind located in Oconomowoc, WI, has made significant contributions to the field of water treatment through his innovative technologies. He holds a total of four patents that focus on enhancing the efficiency and effectiveness of water recycling and distillation processes.
Latest Patents
Tiwari's latest patents showcase his expertise in the treatment of produced water, particularly deoiled water. One such patent, titled "Method for recycling deoiled water using counterflow falling-film evaporators," describes a treatment method that employs evaporation by utilizing a vertical tube heat exchanger bundle. This method ensures that brine is distributed in a falling film along the inside of the tube wall. The technology allows condensing steam to evaporate deoiled water, with the resulting vapor traveling upwards in a counterflow direction. Notably, this design minimizes evaporator sump volume and can utilize a multi-piece construction to reduce the center of gravity, providing significant advantages over traditional vertical tube co-current flow evaporators. These improvements lead to lowered total installed costs and enhanced management of water chemistry.
Another remarkable patent by Tiwari is the "Method for production of high purity distillate from produced water for generation of high pressure steam." This invention presents an evaporation-based zero liquid discharge method, capable of generating high-quality steam from produced water in the heavy oil production industry. By processing the de-oiled water through an evaporation system, the method produces distillate suitable for use in both drum-type boilers and once-through steam generators operating at higher pressures. This system not only achieves over 98% recycling of deoiled water for industrial use but also operates at a higher overall efficiency compared to previous methods.
