Synthermic waste heat evaporators

Reduce or Eliminate Wastewater disposal Costs!

A2 Offers SynThermic Waste Heat Evaporators Eliminate your wastewater disposal problems while providing efficient process cooling. Our SynThermic units use low-temperature waste heat to dispose of wastewater in an innovative evaporation process.

Save Money and Get Free Cooling

Reduce or eliminate water disposal costs.

Provide additional or complete cooling for process, compression, power generation, refrigeration systems and many other applications.

Synthermic Evaporative Benefits
The SynThermic system utilizes an innovative low-temperature process providing a number of advantages:

The process uses low temperature, otherwise unusable, waste heat.

Low operating temperatures permit the use of non-corrosive plastics.

No scaling and fouling with high TDS fluids.

Operates efficiently at varying loads.

Excellent process for concentration and precipitation of dissolved materials.

Portable or permanent installations.

Equipment is reliable and easily maintained in the field.

Can be fully automated for efficient operations at un-manned or remote locations.

Fresh-water recovery option available.

Examples of Savings

Waste brine application at 3,000 bpd for gas field operations saved more than $1200 per day in disposal and transportation costs.

Dilute glycol concentration using waste heat saves nearly $96,500 per year in fuel and boiler conditioning costs.

Food processing plant eliminates liabilities and $100,000 in expenses associated with large evaporative pond for disposal of saline process waters.

Dissolved or Suspended Solids - No Problem!

The SynThermic process is not affected by the Quality or composition of the dissolved solids in the wastewaters.

Fluids up to 320,000 ppm dissolved solids, as well as fluids with high levels of suspended solids have been processed successfully.

Heat Sources

The Synthermic units can use low-grade heat such as heat generated by:

Compressor stations

Refinery heat-exchange systems

Gas lift operations

Boilers or burner flue gas

Wellhead compressors

Genset operations

Refrigeration systems

Units also may be fired directly with oil, gas or methane.

How it Works
u Waste heat is transferred into the heat transfer fluid via a conventional heat exchanger. (2) The heat transfer liquid flows into A2šs proprietary direct-contact heat exchanger, warming the cool brine (3). The warmed brine (4) enters the low-temperature evaporation chamber (5). Airflow into evaporation chamber (6) drops the vapor pressure and the vaporization temperature of the warmed brine. Wastewater is partially vaporized and removed from the evaporator (7). As wastewater vaporizes, salts and other solids collect on membrane surfaces in the evaporator (8). Vibration causes solids to regularly peel into a collection system for removal (9). The cool brine remaining after vaporization is reheated in the heat exchanger and the process repeats (3).
