Ports Pick Seawater Scrubber For Exhaust Emissions
Hamworthy to supply Krystallon exhaust gas cleaning to container vessel
by amanda m. klemp

U.K.-based Hamworthy has been selected to supply its Krystallon exhaust gas cleaning system for container vessel APL England, which travels between Asia and the United States out of the Ports of Los Angeles and Long Beach.

The Ports of Los Angeles and Long Beach have selected Hamworthy’s Krystallon exhaust cleaning system for installation on the APL England container vessel. The emission reduction system is expected to reduce sulfur and particulate matter emissions.

The technology was selected as a trial aimed to reduce sulfur emissions and particulate matter from ships burning heavy fuel oil in the ports. With the Krystallon scrubber, the vessel will be able to continue burning low-cost residual fuels for its auxiliary engines per IMO ECA rules, said Hamworthy. Trials are set to begin this spring on the 5500 TEU vessel’s three MAN 7L32/40 generator sets, each rated for 2900 kW. The exhaust cleaning system is projected to reduce sulfur emissions by 99.9%, even when burning residual fuel oil, said the company. Additionally, it works to reduce particulate matter by 85% and nitrogen oxide by up to 10%.

Hamworthy’s Krystallon exhaust gas scrubber can operate with either seawater or freshwater. The water used is cleaned and treated before being discharged from the ship.

 

The Krystallon system uses the naturally occurring alkalinity in seawater or freshwater to absorb SOx in an engine’s exhaust. Because it uses the seawater, no additional fluids or chemicals are required to achieve the desired reduction in emissions. Both solid particulates and liquid hydrocarbon waste is removed from the water before being discharged from the ship.

Hamworthy said the Krystallon was designed to be simple to operate with no moving parts, except the pump reducing maintenance. As an added feature of the technology, Krystallon also provides silencing benefits near those of a conventional silencer. It’s designed to run cold, but can be operated at temperatures up to 450°C. The seawater pipes are manufactured with glass-reinforced epoxy, which was designed for corrosion resistance, lower flow losses, lighter weight and easier installation, said the company. Hamworthy currently has five systems in service, with 21 in the order book.
