ZERO EMISSION PHILOSOPHY

Wet Electrostatic Precipitator (WESP) dedusting for AN/CAN based fertilizer plant

A CASE HISTORY

Many industries may be required to reduce the amount of dust they release into the environment.  These requirements typically depend on application field, location of plants, type and quantity of dust.

The New project for a new CAN/AN/AS universal granulator of a fertilizers plant was conditionally approved by Czech state authorities in 2013. The outlet dust & ammonia limits were strictly set by environment Authority and no water discharges were admitted, even if disposed to water treatment plants.

Our Customer chose to adopt the WET ESP technology, even if there were no references worldwide in fertilizer plants. No application of WET-ESP in AN/CAN fertilizer industry was known.
The Wet ESP technology was "ad hoc" designed in order to match a good combination between operation costs, reliability of operations, efficiency, safety and zero emission philosophy.

In 2017 the gas treatment plant was started-up successfully, and still works today with excellent results.
