Wärtsilä Hybrid Scrubber System chosen to clean exhaust emissions from 3 new container vessels
(Thomson Reuters ONE) -
Wärtsilä Corporation, Press release, 18 June 2015 at 12.30 pm
Wärtsilä has received an order for Hybrid Scrubber Systems to clean the exhaust
emissions from three 2500 TEU container vessels. The installation has been
ordered by a major European owner and operator and will be carried out at the
Jinhai Heavy Industry Co., Ltd in China. The contract was signed in March 2015
and the systems are scheduled for delivery in December 2015.
The scrubber system, which comprises two scrubber units, will be installed to
clean the exhaust from both the main and auxiliary engines. This arrangement
enables great flexibility and cost savings when operating at different
operational settings. In all, 28 MW of total power output will be handled by the
Wärtsilä system. The system is designed to clean the sulphur oxide (SOx) and
particulates from the exhaust gas.
The design incorporates a cleaning system for the scrubbing wash water. This
ensures that the eventual discharge water is well within the regulatory limits.
Special care has also been given in the design to allow the systems to operate
for extended periods with zero discharge of the effluent scrubbing water. This
is an important advantage when the vessels are operating in environmentally
sensitive waters.
"The ships will be operating at times in harsh climatic conditions and Wärtsilä
has considerable experience in developing scrubber systems technology for use in
challenging marine environments. The system is optimised to give the necessary
flexibility in relation to the ships' operations, with special emphasis given to
minimising the operational costs," says Sigurd Jenssen, Director, Exhaust Gas
Cleaning, Wärtsilä Ship Power.
Wärtsilä will provide engineering and consulting support during the
installation, while the company's global service network will ensure ongoing
technical support throughout the lifecycle of the vessels.
Wärtsilä Hybrid Scrubber Systems enable the use of either closed or open loop
technology to remove SOx from the exhaust. When operating in open loop mode,
exhaust gases enter the system and are sprayed with seawater. Chemicals are not
required since the natural alkalinity of seawater reacts with the sulphur and
cleanses it from the exhaust gas. When operating in closed loop mode, sodium
hydroxide (NaOH) is added to the seawater as an alkali. The hybrid approach
enables operation in closed loop mode when required, for instance when entering
zero discharge areas or where the seawater alkalinity is low, and elsewhere the
switch can be made to open loop using only seawater.
