Air pollution control by using the Dry Electrostatic Precipitator
Our electrostatic precipitators (ESP) generate a corona to electrostatically charge particles and separate them from the flue gas. Each ESP system is designed to ensure effective control of particulate emissions. Acid gas pollutants (SOx, HCl, and HF) are removed by the addition of an adsorbent and are also separated in the ESP.
For the separation of NOx, the so-called SCR process is used and is installed downstream of the ESP.
INTERPROJEKT offers customized systems for both the separation of individual components and complete systems.
Particle control by using Dry Electrostatic Precipitator
In our plate electrostatic precipitators particles are collected by ionization.
- Our modular design with 5 basic modules offers enormous advantages: any cross- sectional design is possible, fast assembly by pre-assembled modules, as well as an uncomplicated extension of existing systems
- High separation efficiency with low energy consumption
- Efficient pneumatic cleaning system of the electrodes
- Maintenance and cleaning friendly due to unrestricted accessibility of the entire system
Removal of SOx, HCI and HF by using dry desulfurization
In a specially developed reaction tower (scrubber) the flue gas is mixed with the added hydrated lime whereby a separation of SOx, HCI and HF is achieved.
- By optimal mixing with the sorbent a maximum degree of separation is achieved.
- By an optional cooler reactor unit the flue gas can be cooled down by means of water cooling in the same reaction tower.
Removal of NOx by using selective catalytic reduction (SCR)
By adding ammonia water or urea as a reducing agent, NOx is separated using the selective catalytic reduction (SCR) process.
- Aspecial sealing of the catalyst modules reduces the ammonia slip.
- By a newly developed cleaning process of the catalyst surface the compressed air consumption is minimized and the life-time of the catalyst is extended.
- By a permanently cleaned catalyst surface the pressure loss in the catalysts is reduced.
