ABOUT THE TECHNOLOGY

Recovering and repurposing clean water and energy

TMCAqua - Transport Membrane Condenser is a patented technology licensed from Gas Technology Institute designed to recover waste heat and clean water from hot humid exhaust stacks.

Ceramic membranes have been used in liquid discharge water filtration systems for decades. The TMC technology starts with these same ceramic membrane tubes and applies a nano-ceramic coating on the tube surface to create a unique pore geometry that enhances capillary condensation of moisture trapped in hot exhaust gasses.

WHY IT MATTERS

Water and energy are two of the most critical utilities used in industrial processes

Water and energy are two of the most critical utilities used in industrial processes. Depending on the locality, the availability of water, energy, or both can be limited, and therefore any opportunity to improve the sustainability of these resources would deliver value and payback.

In many industrial heating/drying operations, as much as half the water in the process escapes through the stack into the atmosphere, carrying with it valuable heat energy that is difficult, if not impossible to recover. Depending on the moisture content and temperature of the exhaust stack gasses, TMCAqua can recover as much as 80% of the available water and enthalpy and return it back to the process.

Many industrial processes use Natural gas as a source of energy. Natural gas combustion produces water as a byproduct that goes up the exhaust as part of the exhaust gasses.

TMCAqua represents a new source of water for such applications along with the energy recovery that delivers quick payback.

These ceramic tubes are arranged in heat exchanger modules (10” X 10” X 36”), several modules are then arranged in racks and placed in hot exhaust gas streams.

HOW IT WORKS

3-in-1 System

The TMCAqua system, as a whole, therefore performs three critical functions simultaneously, namely it is a condenser, condensing and recovering water, a heat exchanger, recovering enthalpy, both latent and sensible and it is a filtration device, filtering the recovered water to deliver clean water.

Natural Gas combustion applications:

Package Boilers

Each MCF/MMBtu of natural gas combustion produces 12.5 gallons of water in the combustion exhaust gasses. This represents roughly 18% moisture by volume in the flue gas and could be as much as 10% of the total energy input into the boiler.

TMCAqua can recover roughly half the enthalpy and half the water contained in this combustion exhaust gas. The water so recovered is clean hot water at 175 DegF (77 DegC) and can be directly used for Boiler Feedwater thereby increasing boiler efficiency. Total boiler efficiency of up to 95% is achievable with TMCAqua.

Natural Gas combustion applications:

Utility Boilers and Combined Cycle

Similar to package boilers, utility gas boilers burn natural gas to produce steam that in turn generates electricity. The characteristics of the combustion exhaust gasses are also similar and therefore TMCAqua can recover enthalpy and water from these exhaust gasses and return them to the process for use as make-up water into boiler feedwater thereby improving boiler efficiency.

Over the past decade many coal boilers have been re-powered with gas. Such coal-to-gas conversion boilers face challenges related to capacity and efficiency since the heat transfer surfaces that were optimized for coal combustion are not designed to deliver the best results for gas combustion. Such conversions range from large boilers, wall or T-Fired to stoker boilers. TMCAqua is particularly useful in such situations where the hot water recovered can help improve and recover some of the efficiency losses.

Another type of gas based power system where TMCAqua can drive efficiency gains is combined cycle units with heat recovery steam generators (HRSGs). The hot water recovered by TMCAqua can go back into the HRSG delivering efficiency improvement.

Industrial heater/dryers:

Spray Dryers

A Spray Dryer is a piece of equipment where a liquid or slurry feedstock is dried to produce a powder. The moisture contained in the liquid or slurry is evaporated into a hot humid gas stream which is then passed through a cyclone and/or baghouse and exhausted up the stack.

The moisture content in spray dryer exhaust can be as high as 50% and TMCAqua can deliver water and energy recovery in such gasses of up to 80%.

Industrial heater/dryers:

Paper Dryers

In the paper making process, the paper dryer is a critical piece of equipment where the moisture in the paper is driven out and exhausted from the stack. The moisture content of this stack is typically about 50% and TMCAqua can recover as much as 80% of the water and enthalpy contained in these stack gasses.

Industrial heater/dryers:

Product Dryers, Ovens and Furnaces

Other applications for TMCAqua include product dryers and natural gas fired ovens and furnaces.
