Strategic Partnership of Thermal Purification Technologies and California Clearwater Resources

Thermal Purifications Technologies Limited (TPTec), a technology development company in the water sector, and California Clearwater Resources (CCR), a company dedicated to finding environmentally responsible, economic ways to provide clean, previously unavailable water to California’s water supplies

TPTec North America’s and CCR’s first project will be a Low Temperature Distillation (LTDis) plant to treat produced water. Located near Bakersfield, California, this plant is now in the final stages of planning. When completed, it will produce 20,000 barrels per day of (clean) water from produced water coming from oil production. In a second phase the reject stream will be treated with a Low Temperature Dryer (LTDry) thus avoiding the need to inject the reject in deep wells.

TPTec is focused on developing clean and efficient solutions for multiple applications such as cleaning seawater, brine and polluted water including separation of water and solids. TPTec uses advanced thermodynamics to build simple, robust and efficient plants that can use existing waste or low value streams to purify challenging feeds with a minimum of residual effluents. TPTec’s technology portfolio includes award winning and patented LTDis (Low Temperature Distillation) and patented LTDry (Low Temperature Drying) technologies.

The demonstration plant will integrate both the LTDis and LTDry technologies, treating the produced water in two phases. The first phase uses LTDis, which alone can achieve a conversion ratio of some 75-88% depending on the feed water, allowing for recycle and reuse of much of the water – an important consideration in any location but especially so in drought-stricken California. With an additional upgrade for isolating high saline water and precipitation loops/centrifuges, the conversion can be brought up to some 90-92% and thus achieve ZLD-wet. With the addition of LTDry, the remaining wet sludge will be dried thus achieving ZLD-dry and avoiding the need to dispose of the reject in deep wells.

CCR has been researching California and other water markets and water purification technologies for over five years. CCR’s water purification efforts are concentrated on oil and gas produced water as well as industrial water and desalination. CCR is currently focused on California and Texas with three demonstration plants in the planning phase that will purify produced water into potable water. The plants, which include the TPTec North America project, range in capacity from 20,000 – 200,000 barrels per day. 

“CCR is very excited about our partnership with TPTec. Our management team includes people from the oil and gas industry and the water industry. With TPTec as our partner, we can cover a wide spectrum of potential water purification opportunities. We believe there are several underutilized sources of water across North America that can be cleaned economically and environmentally responsibly,’” said Jeff Roberts, President of CCR. “After a thorough technology evaluation, we have chosen to work with TPTec as their technologies provide us with a unique solution that is reliable, robust and effective in producing exceptionally clean water. Their ability to go to zero discharge gives us the flexibility to work in a variety of environments. This makes the LTDis and LTDry technologies particularly suited for the needs of oil and gas operators.”
