Alfa Laval has announced that continues to move swiftly towards the submission of a US Coast Guard (USCG) type approval application for Alfa Laval PureBallast 3.1. The company has performed half of the required land-based tests and is set to conclude the remainder of these within Q2.

PureNOx Prime, Alfa Laval’s new PureNOx solution for water treatment in Exhaust Gas Recirculation (EGR), will be part of EGR systems on five very large ethane carriers (VLECs) to be operated by United Ethane Carriers (UEC). ABB says that this breakthrough order' from MAN Diesel & Turbo comes only a short time after PureNOx Prime was introduced to the market.

Alfa Laval has announced that its PureSOx U-design scrubber system has been made available.The improvements, which further increase the U-design’s flexibility, were announced around the same time as a date for decision on the 2020 global fuel sulphur cap.

Alfa Laval announced that its Test & Training Centre in Aalborg, Denmark will soon be expanded to five times its current size. This development, focused on LNG and other alternative fuels, will address new challenges and possibilities for marine customers as they strive to meet environmental and energy targets.

Alfa Laval is actively training its network of engineering partners for Alfa Laval PureBallast to ensure that requisite design and installation skills are in place to meet the demand

Alfa Laval claims Exhaust Gas Recirculation (EGR) on MAN B&W engines combined with a new pressurized EGR economizer from Alfa Laval offers the potential for massive fuel savings.“EGR provides Tier III NOx compliance with a very compact footprint, but compliance itself is only part of the full potential,” says John Pedersen, Business Manager, Boilers, Combustion & Heaters at Alfa Laval. “Working closely with MAN Diesel & Turbo to optimize the EGR technology, we saw additional opportunities through our expertise in marine boilers. The result is the Alfa Laval Aalborg EGR-HPE economizer, which paves the way for extraordinary energy and fuel savings.”Developed by Alfa Laval in close cooperation with MAN Diesel & Turbo, the Aalborg EGR-HPE is a revolutionary new economizer enclosed in a pressure casing. Placed in-line ahead of the pre-scrubber sprayers in the EGR circuit, it can be used for a number of advantages. If connected to a conventional waste heat recovery system, for example, waste heat recovery becomes substantially more efficient – and is possible at significantly lower engine loads.“By moving the break point for waste heat recovery from a medium engine load down to a low load, the Aalborg EGR-HPE enables even slower steaming,” says Pedersen. “That ...

  Alfa Laval has become the first company to be approved by MAN Diesel & Turbo to supply a water treatment system, PureNOx, for MAN’s exhaust gas recirculation (EGR) scrubber. The approval comes with less than a year to go before the International Maritime Organization (IMO) Tier III NOx standards take effect on January 1, 2016. A comprehensive NOx abatement technology, the EGR will be used with the MAN’s two-stroke marine engines to reduce NOx emissions. The EGR is an alternative to selective catalytic reduction (SCR) technology; both EGR and SCR are compliant with the IMO NOx Technical Code. Long-term cooperation paves the way to approval In 2012, Alfa Laval signed a cooperation agreement with MAN to develop the water treatment system for cleaning scrubber water in their EGR system. PureNOx not only prevents soot and compounds derived from the exhaust gas from accumulating in the EGR scrubber and corroding the engine, but also enables the bleed-off of clean water overboard in compliance with IMO criteria. “From the start, we have worked closely with MAN to develop and refine the water treatment system,” says Kristina Effler, Global Business Manager, Water Treatment Exhaust Gas Emissions. “Receiving the MAN Certificate of Approval ...

  Grimaldi Group  has ordered its tenth installation of Alfa Laval’s exhaust gas cleaning system. Installations are underway aboard Atlantic Container Line newbuilds that will be the largest ConRos in the world, and the Group’s tenth system was recently ordered for yet another Finnlines vessel. The Grimaldi Group’s first experience with PureSOx was in 2014, when potential SOx scrubber solutions were evaluated for four of its existing Finnlines vessels. All four of the Finnlines vessels, which offer service in the North Sea and Baltic Sea, were retrofitted with open-loop PureSOx systems sized for operation in low-alkalinity Baltic waters. The Finnmill and Finnpulp received multiple-inlet systems, while single-inlet systems were installed aboard the Finnhawk and Finnkraft. In all cases, the systems were designed to facilitate later conversion into hybrid systems. Class approval for the first systems Alfa Laval has a long history of experience in working with scrubbers, as well as a structured method for preparing a PureSOx installation. In the Finnlines projects, this contributed to an extremely efficient retrofit procedure. The vessels were able to run on HFO as soon as installation was completed, and the commissioning of the PureSOx systems by Alfa Laval took  around 1.5 weeks per vessel. After this, ...

  The explosion-proof version of Alfa Laval’s chemical-free ballast water treatment system, PureBallast 3.1 EX, has received approval from the U.S. Coast Guard for use on barges sailing in U.S. coastal waters. The approval comes a year after Alfa Laval PureBallast received an IECEx Certificate of Conformity from the International Electrotechnical Commission (IEC) for use in explosive atmospheres on board ships in international waters. Alfa Laval introduced PureBallast, the first commercial chemical-free ballast water treatment system in 2006. Three years later, the company launched PureBallast 2.0 EX, which complied with ATEX directives, the European Union Directives for equipment use in potentially explosive atmospheres, such those on tankers carrying volatile cargo. Last year, PureBallast EX received an IECEx Certificate of Conformity from the International Electrotechnical Commission (IEC) for use in explosive atmospheres on board ships in international waters. Now this third-generation ballast water treatment system is approved for use on barge applications sailing in U.S. coastal waters, making it one of the first to be approved by the U.S. Coast Guard. “We’re pleased that PureBallast EX meets the stringent criteria for approval by the U.S. Coast Guard,” says Alfa Laval’s Stephen Westerling Greer, Global Business Manager of PureBallast. “U.S. Coast Guard ...

  The proven capabilities of Alfa Laval PureBallast – which include operation in fresh, brackish or marine water and in low-clarity water with just 42% UV transmittance – are now available to significantly smaller vessels. Alfa Laval’s ballast water treatment technology, which was submitted for USCG approval in March 2015, can now be used in systems for flows of 87 m3/h. A variety of vessel types, including offshore supply vessels, will benefit from the extended PureBallast flow range. The lower capacities are enabled by a new reactor, optimized for system sizes from 170 m3/h down to 87 m3/h. This is a major expansion of the PureBallast family, where a 250 m3/h system was previously the smallest available. “Lower flow rates will make PureBallast accessible to smaller vessels, whose quality and performance needs mirror the needs of larger vessels,” says Stephen Westerling Greer, Global Business Manager for PureBallast. “In some cases, as in the offshore industry, small vessel needs can be all the more extreme.” No compromises in design or operation Westerling-Greer points out that no shortcuts have been taken in the design process. “Smaller PureBallast systems will be a full match for their larger counterparts,” he says. “The reactors are ...
