The Coomtech Kinetic Energy Drying solution to dry bulk solids materials of surface moisture is unique, working by shearing the moisture off particles in controlled turbulent air flow which is warmed to an average 100C optimising its ability to hold the water separate from the particles. It is a lean phase process treating particles in under a second, dealing with a range of moisture levels dependant upon the material dried. It presents a singular and viable alternative to traditional thermal drying - heating water for vaporisation using temperatures in excess of 400C. Because it is only heating air to a low temperature, the Coomtech Kinetic Energy Drying system delivers a lower cost and lower emissions system over the life of a plant. It’s a modular configuration that can manage from 32,000 mtpa up to multiple hundreds of thousands of tonnes. The plant can integrate with existing systems including using low grade waste heat sources or can be a standalone remote plant.

The Environmental Benefits

• •Since air heats more efficiently than water energy costs can be cut by up to 75% from thermal drying by traditional technologies.
• •In cutting the energy requirement then on a like for like fuel and performance basis the Coomtech Kinetic Energy Drying System can cut up to 75% of the CO2 emissions versus a thermal drying plant.
• •The system is gentle and low temperature for materials sensitive to those characteristics and tends to break up softer agglomerates sending the particle size distribution toward the finer end for most products with agglomerating tendencies.
• •The Coomtech Kinetic Dryer can save up to 75% CO2 emissions per tonne of dried material compared to various designs and levels of efficient thermal drier currently available
• •The Coomtech Kinetic Dryer can save 75% of the energy use against thermal driers in most cases and more in some. It does this through only heating the processing air to circa 85°C and not having to heat up the water itself to vaporise it,
• •Water recovered in the process can be recycled or reused for example 17% removed from a tonne creates c.170kg of water - vital in some regions today and increasingly important in future.

The Financial Benefits

• •Operating energy costs are up to 75% less than traditional technology because we are heating air and do not have to heat the water being removed to the point of vaporising it.
• •The consequence of reduced energy demand is CO2 emissions are reduced and in todays market carbon saved has a value and is rising in value in the European and in the global trading markets.
• •The scale of savings on OPEX and potential carbon trades mean that payback periods can be as low as 18 to 36 months for Coomtech over thermal technologies.
