New Scrubber System From Alfa Laval

12 June 2020

Alfa Laval said its new PureSOx Express open-loop scrubber is designed to be a simple and cost-effective fit for smaller vessels.

The company said that the cost of installing scrubbers for Sox compliance on smaller vessels, like handymax bulkers or product tankers, sometimes outweighed the benefits. The Alfa Laval PureSOx Express is designed to make it simple for these vessels to continue using HFO and comply with SOx regulations.

Although the new PureSOx Express is an open-loop PureSOx system, it is delivered as a fully enclosed module and designed to be a simple and cost-efficient fit on smaller vessels.

Quick Installation

“PureSOx Express uses the proven PureSOx technology that’s already used on hundreds of vessels,” said Steven Pieters, sales director, Exhaust Gas Cleaning. “But it can be lifted on board and connected without a specialized scrubber team, which means less work at the shipyard and an installation time of just 10–14 days. Not only is the initial investment lower, the vessel can return more quickly to its money-making operations.”

The PureSOx Express is designed for up to 75 tonnes of exhaust gas per hour and engine power up to 10 MW. This makes it a one-size-fits-all solution for many vessels of 40 000–65 000 DWT, which typically include bulkers and product tankers.

Hybrid Ready

The scrubber is hybrid-ready, with connections present for a later conversion to a hybrid system. This makes the module as future-proof as it is cost-efficient, the company said.

“Customers who hesitate to commit to a hybrid can feel comfortable choosing PureSOx Express,” said Pieters. “PureSOx Express offers flexibility to add equipment for closed-loop operation down the road, should they need to meet stricter water discharge regulations.”

In addition to a packed scrubber bed, it features a water trap designed to ensure safety by preventing any backflow to the engine. Steered with Alfa Laval Touch Control in the same way as other PureSOx systems, it offers the same ease of use and connectivity options. Perhaps most importantly, it builds on over 10 years of scrubber installations and operating experience at sea.

“Since the first PureSOx system sailed in 2009, we’ve optimized our offering by learning from each installation,” said Pieters. “All that knowledge has also gone into PureSOx Express. No matter which type of PureSOx system they install, customers can count on efficient compliance, supported by Alfa Laval’s global network and a comprehensive portfolio of scrubber services – including data-driven services through PureSOx Connect. PureSOx Express is yet another way of keeping our customers ahead.”
