Behind the Technology:  How TMCAqua Evolves Your Corporate Sustainability Practices

Did you know  industrial operations consume about 19% of all available freshwater worldwide? From spray dryers that produce infant formula to packaged-boilers that heat vast institutions, combustion gas boilers and spray dryers play an essential role in our daily lives. TMCAqua, a GreenSwans technology,  is a catalyst for improved efficiency and the sustainability of boilers and dryers, widely used in industry today.

Until now, water sustainability solutions have mostly focused on water and wastewater going down the drain. However in industrial drying processes, as much as half the water consumed goes up the stack never to be recovered along with the energy contained within it. 

Combustion processes that burn natural gas or hydrogen generate water as part of the process which also goes up the stack and constitutes about 18% of the gas stream. TMCAqua is one of the only commercial solutions that can recover this water and energy as clean hot water that can be reused in the process to deliver energy and water sustainability.  Recent pilots conducted with a large consumer product goods business, has verified that TMCAqua can recover up to 80% of the enthalpy and water contained in these hot, humid stack gasses. The clean hot water can then be recirculated immediately in the industrial process.

How It Works 

TMCAqua utilizes patented nano-ceramic tubes that are arranged in heat exchanger bundles. The bundles seamlessly attach to natural gas package steam boilers or dryers used in buildings such as universities, hospitals and municipal buildings, as well as industrial facilities such as chemical, food, refining and consumer packaged goods facilities. The tubes condense, recover, and filter the water for reuse.  In addition to significant enthalpy and water recovery, the technology improves overall unit efficiency to deliver energy cost savings and the associated carbon reduction impact. 

A Multi-Functional Device:

TMCAqua technology is unique because it combines the capabilities of three technologies in one low-cost package: a condenser, a heat exchanger, and a membrane filter. Its porous nano-coated ceramic membranes recover clean water and energy through capillary condensation from low-temperature hot, humid gas streams. TMCAqua separates itself from other technologies as the condensation on the nano-ceramic tubes happens at the capillary dew point, which is 15 to 20 degrees fahrenheit above the bulk gas dew point. While the nano-pores in the ceramic coating condense water which is transported through the membrane wall and collected as clean water, the tube surface itself remains dry thereby avoiding dissolving acidic gasses into the water which produces acidic water. Therefore, TMCAqua delivers clean water and not acidic water. 

Applications

Spray Drying

Spray drying is an industrial process where liquid or slurry, a semiliquid, is fed into a reactor where it is atomized and exposed to temperature, where the water evaporates and solids are collected as a product. A spray dryer is typically connected to a particulate collection device downstream, such as a cyclone separator or a baghouse.

Some examples of this application include chemical processes, paints and pigments, food, nutrition, and pharmaceuticals.

Paper Drying

The industrial paper-making process utilizes a large amount of water in the pulp-making stage. Once the paper is rolled out, it still contains a lot of water that must be evaporated. This is done in special dryers, where the moisture is then exhausted through vents into the atmosphere. 

Package Boilers

Package boilers are used in a majority of industrial and commercial facilities, including food, pharmaceutical, chemical and petrochemical, to provide steam for processing and heating. Package boilers generally use natural gas for combustion, which produces water in the exhaust gas stream. Each Metric Million British Thermal Unit (MMBTU) of gas combusted produces roughly 12.5 gallons of water per hour. This is a vapor-rich gas stream that is an ideal application for the TMCAqua technology.

Typical results for gas combustion applications are as much as a 15% improvement in efficiency, and a 40-60% recovery of available moisture as clean water.

Commercial Laundry 

Steam tunnels are used in several industries to heat and treat products. In the commercial laundry industry, steam tunnels are used for removing wrinkles from garments. The steam from the tunnel is typically exhausted up a stack, where it is vented.

Commercial Laundry is an optimal application for TMCAqua to recover water and energy from its stack. As much as 60% of the water and available enthalpy can be recovered by TMCAqua to be reused in the process as hot water, or to make new steam.

The TMCAqua Difference

As Industrial practices shift towards decarbonization, companies and institutions, many using older boiler equipment in particular, face sustainability challenges. TMCAqua is especially effective in these cases where the recovered hot water can enhance and recover the efficiency losses. TMCAqua is the low cost, energy efficient, boiler product to help reach your company’s environmental goals.

In Industrial drying processes, where large amounts of water and energy are currently used, as much as half the water and the associated energy is lost to the atmosphere. TMCAqua is the technology that can bring back as much as 80% of this water and energy
