The DryEGCS
is based on a long-time proven technology applied on land based exhaust gas cleaning systems where calcium powder is used as agent for the absorption of sulphur.
A special calcium hydroxide [Ca(OH)2] granulate was developed to enable the application of this technology on board of vessels. This granulate needs significantly less space compared to land based applications and removes more than 99% of the sulphur oxides (SOx).
The absorption of sulphur oxides leads to calcium sulphate, commonly known as gypsum.

The DryEGCS® integrated downstream the turbo charger can be operated at temperatures between 210 - 440°C. The exothermic absorption process causes no temperature loss of the exhaust gas, hence boilers and economizers can be operated as usual.
The schematic design of the DryEGCS® process illustrates the way of the exhaust gas in and out of the absorber where the chemical reaction between granulate and exhaust gas takes place.
The absorber acts as particle filter as well since it removes rough sooty particles and other residues from the exhaust gas.
The DryEGCS® causes a back pressure of up to 12 mbar, according to engine manufacturers a tolerable value. In case of need a fan could be integrated to minimize this back pressure
A silo on top of the absorber supplies fresh granulates. A controlled extraction of the residues underneath the absorber regulates its consumption.
Pneumatic transportation of fresh granulates or residues allow flexible planning of storage tank locations onboard.
A control cabinet automatically inspects all operational parameters. The integrated ‘scheme B’ monitoring system continuously plots the emission values and proves that all regulations are met.
In case of need the DryEGCS® can easily be shut down by using the bypass.
