Crystallization

Separate and purify Lithium, Manganese, and high value chemicals using low energy crystallizers and separators. Guide fast track testing programs as required.

EXPERIENCE

  • Scraped Surface Crystallizer expert for design and use in the Chemical, Refining, and Pharmaceutical industries, low and high RPM process scenarios included.

  • Hydraulic Wash Column (HWC) applications for solid liquid separation and solid purification.

  • Chemical Separation Plant design by developing balances, process flow diagrams, P&IDs, hydraulic pressure drop calculations, pump data sheets and selection, crystallizer design, separator design, melt heater design, vessel design, valve selection, instrument data sheets and selection, wiring diagrams, control system logic/design, and precise electric tracing design.

  • PLC, HMI, and Computer control and monitoring system design and programming. Programming with Rockwell, Siemens, and GE systems.

  • Process design with hydro cyclones, plate filters, vacuum filters, pusher centrifuges, bowl centrifuges, settlers, drum crystallizers, and more.

  • Successful crystallization of chemicals such as p-xylene, acrylic acid, acetic acid, p-nitrochlorobenzene, Glauber salts, lithium salts, phosphoric acid, amorphous (non-crystalline) waxes, non-crystalline fatty acids, and more.

  • Solid liquid flow design, pipe and tube sizing, layout, and orientation.

  • Participated in successful R&D using melt crystallization for Pharma industry.

  • Design of low temperature “cold” line tracing, sizing and specifying chillers, and utility system design.

  • Programmed design software for crystallizers and for crystallizer separation plants.

ADDITIONAL BACKGROUND

  • Partnered with Crystallization experts throughout the world. Keen awareness of past problems and current solutions for crystallization systems.

  • Web implementation of Kozeny-Carmen equation for packed bed pressure drop for a variety of solids.

  • Web implementation of Turton and Levenspiel (1986) for settling velocity for a variety of individual particles.

  • Web Implementation of Richardson and Zaki (1954) for hindered velocity of many particles (suspensions) of various shapes.

  • Gave technical presentations on Chemical Separation Plant desirability throughout Japan, Taiwan, PRC, India, Netherlands, and the United States.
