Technical Case
Krystallon’s innovative approach to pollution abatement technology is designed to achieve compliance with all current global legislation - be it IMO, European or American. Fitting Krystallon sea water scrubbers will also future-proof your vessels from the next rounds of legislation with regard to SOx emission reduction and also PM emissions. The following high standards and levels of reliability will apply:
- 100% sulphur removal
- 3.5% fuel S equivalent of 0.1% fuel S emissions as the base case
- Over 80% particulate removal from the exhaust gas
- Full instrumentation to monitor both scrubbing efficiency and water discharge quality
- Provides compliance with current SECAs and addresses pending legislative changes
- Meets EU requirements for 0.1% sulphur fuel for all vessels at berth in the EU from 1st January 2010
- Exceeds existing and expected environmental criteria for air and water discharge quality
- Performs all of the above, reliably over a 25 year life cycle
To achieve this, the Krystallon Seawater Scrubber maximizes the use of the following key system components:
- Scrubbing unit – one for each engine or a combined unit with gas path separation for auxiliary engines.
- Wash water treatment system – Normally one treatment system is capable of handling all wash water flow from main engine and auxiliary engine. The wash water treatment plant removes oil and particulates from the wash water for safe disposal as oil sludge (typically 100 tonne fuel consumption creates 200kg of oily sludge).
- Continuous monitoring of exhaust gases utilizing latest Cascade laser technology. This technology provides in stack gas measurement for CO2, SO2, NO and NO2. Utilizing the CO2:SO2 ratio in accordance with IMO Sea Water Scrubbing guidelines establishes compliance in SECAs of equivalence or below of 1.5% sulphur fuel. In fact with virtually 100% scrubbing efficiency it is rare to detect more than 5ppm to 10ppm SO2 after the scrubber when using 3.5% sulphur fuel.
- Continuous monitoring of wash water discharge – Utilizing pH and Oil content measurement, (the latter to levels of ppb) the continuous compliance with in port wash water criteria can be demonstrated.
- Data recording and transmission – The Krystallon data recording system complies with data integrity, fraud and tamper evident requirement for Port State inspection of vessel position and emissions for any point in time for up to at least 3 years of history.
- Pumps including variable speed control – All system pumps and controls and all sensing and system protection.
- Glass Reinforced epoxy pipe work – all pipe work is supplied to comply with the environmental requirements of a sea water scrubbing system.
