Drupps Vapor
Recycling pure water and energy from dirty industrial airstreams
Your airborne outlet is a goldmine. Don’t waste it.
Drupps Vapor is a game-changing system for recovery of water and energy from dirty industry outlets. Vapor technology is based on Drupps’ unique zero-water scrubbing technology that requires a bare minimum of added water. Effective cleaning of the airstream enables water recovery by downstream heat exchanging.
Drupps Vapor comes in two options — Vapor Water and Vapor Energy, each optimized to maximize recovery of water or energy. Choose the one that best suits your priorities.

Drupps Vapor Water
Water recovery from dirty airstreams
Drupps Vapor Water is optimized for water recovery from dirty industry outlets comprising Drupps Vapor’s unique zero-water scrubbing technology that requires a bare minimum of added water. Water is generated by heat exchanging with ambient air in a dry cooler.
Setup
Drupps Vapor Water is built on the outside of the plant in a three-level structure and connected to the exit airflow duct coming from the dryer.
Airborne dirt is removed by the scrubber (blue module) before airborne wastewater is condensed by heat exchanging with ambient air (grey module). Water is collected (light blue module). Dirt is collected and removed (orange module).
Use Case
Water recovery from airborne wastewater for ceramic tile manufacturer
Need: A ceramic tiles manufacturer in need of increased water efficiency.
Conditions: High content of fine clay particles in the exit airflow coming from spray dryers, preventing the use of air-cooled condensers. Airflow temperature is 76°C.
Solution: Cleaning of the exit airflow by wet scrubbing with zero water loss in combination with air-cooled condensing by ambient air in a dry cooler.
Setup: Drupps Vapor Water is connected to the exit air ventilation duct in a structure similar to the image above, effectively removing all particles in the airstream through scrubbing. In the next step water is condensed from the cleaned airstream through air cooling. No energy is recycled.
Economics: The economics of this spray dryer upgrade can be viewed in the table below.
Drupps Vapor Energy
Water and heat recovery from dirty airstreams
Drupps Vapor Energy is optimized for energy recovery from dirty industry outlets comprising Drupps Vapor’s unique zero-water scrubbing technology that requires a bare minimum of added water. Water is generated from the outflow through heat-exchanging with incoming ambient air.
Setup
Drupps Vapor Energy is built on the outside of the plant in a three-level structure and connected to both the dryer’s exit and incoming airflow ducts.
Airborne dirt is removed by the scrubber (blue module) before airborne wastewater is condensed by heat exchanging with incoming ambient air which is pre-heated, lowering the dryer’s heating need.
Use Case
Energy recovery from airborne wastewater for pet food producer
Need: A pet food producer in need of increased energy efficiency.
Conditions: High content of fine dust particles in the exit airflow coming from spray dryers, preventing the use of air-cooled condensers. Airflow temperature is 65°C.
Solution: Cleaning of the exit airflow by wet scrubbing with zero water loss in combination with heat exchanging with incoming ambient air going to the spray dryer.
Setup: Drupps Vapor Energy is connected to the exit air ventilation duct and incoming air duct, respectively. The exit airflow is cleaned from particles through zero-water-loss wet scrubbing before heat-exchanging with an incoming ambient airflow, condensing water from the exit airflow while pre-heating the incoming airflow going to the spray dryer.
Economics: The economics of this spray dryer upgrade can be viewed in the table below.
