Thermal Systems
Multi Effect Distillation/Evaporation (MED/E) - Innovative in-house designed Multi Effect Distillation/Evaporation (MED/E) re-engineered design with innovative technologies for energy savings and zero liquid discharge.
The MED/E is designed to work seamlessly with our Patented Technologies High Performance Flat Plate Collectors and Super Heat Generator.
Multi Effect Distillation/Evaporation (MED/E) system is designed to recover over 95% of the water as distillate from any high TDS stream (such as Produced Water) and render the TDS salts into an amenable slurry suitable for recovery as crystallized salts using a Crystallizer.
-
Compatible with a True ZLD.
-
Ease of integrating crystallizers with the effects.
-
Higher thermal efficiency
-
RA Heat’s MED/E utilizes the forward flow.
-
HPFPC and & SHG significantly reduce the required thermal energy.
This is accomplished using the proven MED/E technology, with our innovative in-house design, with improved heat transfer of the latent heat into the MED/E, giving an increased efficiency for thermal energy transfer.
'RA Heat' have re-engineered design with innovative technologies for energy savings and zero liquid discharge. The MED is designed to work seamlessly with our Patented Technologies High Performance Flat Plate Collectors and Super Heat Generator. designed a single solution to solar thermal desalination with the complete design from start till finish.
Providing a true clean solar thermal energy to environmentally ZLD solution to desalination
This is accomplished using the proven MED technology, with our innovative in-house design, with improved heat transfer of the latent heat into the MED's, giving an increased efficiency for thermal energy transfer.
Super Heat Generator
The patented Super Heat Generator (SHG) has been designed to complement and enhance the efficiency of our innovative designed Thermal Multi Effect Distillation/Evaporation (MED/E) system and optimizing the latent heat transfer and resulting in improved efficiency.
This reduces the energy that would traditionally be needed to generate the required thermal energy, thus offering a savings in both OPEX and CAPEX.
The SHG supplies 83% of the steam and the Solar Thermal Boiler provides 17%.
The latent heat of evaporation is between 80-90% of the steam’s energy (Dependent on the salinity).
The Super Heat Generator, optimizes steam, recycling for efficient energy generation, offering enhanced Performance Ratio (PR) and the highest Gained Output Ratio (GOR) available in the thermal desalination.
High-temperature Crystallization process - Zero Liquid Discharge
Discharge of dense brine is defined as water with a salt concentration higher than 50 parts per thousand.
As a result of the desalination process, a dense brine stream is discharged into the environment, which adversely affects flora and fauna of the region, be it inland or at sea. These discharges, when released onto land, increase the salinity of the soil, thus affecting the surrounding fauna. The discharge of brine stream into the sea can cause significant damage to the marine ecosystem
It is in this field, where RA Heat provides solutions with a reduced reliance on power and zero liquid discharge.
By integrating the standard multiple-effect desalination system (MED) technology with a high-temperature desorption process and a high-temperature crystallization process to achieve Zero Liquid Discharge (ZLD).
Extracting all the water-vapor volume from the brine slurry of the MED system enables an energy-efficient, ZLD treatment.
This provides a wastewater management strategy that eliminates liquid waste and enhances water usage efficiency.
This can include Industrial wastewater, ground water, RO hypersaline dense brine and Oil & Gas well production water.
The collection of commercial salts in a ZLD system through Sea Water Mining (SWM), using the hydrometallurgy processes is financially viable in recovering Sodium, Magnesium, Potassium, Lithium, and Rubidium
As our environmental awareness and demand for cleaner energy rises, the value of these minerals makes mining the hyper-saline fluid discharge a viable proposition and the extraction cost offset the ZLD and water production costs.
