Nature Group, the market leader in handling MARPOL (marine pollution) waste streams and offshore waste from the oil industry, has installed a Babcock Wanson HEB 420 Hot Water Boiler into one of its newest overseas treatment facilities, which is designed to treat oil contaminated wastewater.
Cleaning Up Marine Waste
In line with MARPOL Annexes I-V, which aims to preserve the marine environment through the elimination of pollution by oil and other harmful substances, Nature Group’s Port Reception Facilities collect and treat more than 200,000 m3 of offshore waste every year. The contaminated water is treated by various treatment processes, including bacteria from natural biological processes, and the oil recovered during the treatment is recycled for further industrial use.
Babcock Wanson HEB 420 Hot Water Boiler
In this latest facility, the Babcock Wanson HEB 420 Hot Water Boiler is used to pre heat the tanks containing the wastewater, up to 100°C at 5 bar pressure, before it enters the treatment process. The treated water is safely discharged into the sea whist the recovered oil is fed back into the process to fuel the Hot Water Boiler for maximum efficiency. A true example of efficient energy recycling!
The HEB 420 was installed by Babcock Wanson UK in a bespoke boiler house, which is also home to the fuel tank, pipework and boiler controls. The system is operated approximately every three months when enough wastewater has been collected and stored.
Babcock Wanson’s HEB Boiler is a forced-circulation, fully automatic, oil or gas fired packaged unit, specifically designed for high efficiency and long working life. The reverse flame design provides optimum furnace loading and the radial firetube assembly minimises material stresses. An easily reversible front door allows simple and quick access for inspection of the combustion chamber and reversal tubes without the need to remove the burner.

“The Thermal Oxidiser is the most efficient way of removing any smells and it’s also very straightforward to use. We have been a customer of Babcock Wanson for many years and have always enjoyed a good service.”

“A major carbon footprint reduction will be achieved when the scheme currently in progress to change the main boiler fuel from heating oil to gas is completed in summer 2010. This £900k project will reduce our carbon emissions via energy usage by around 15% by removing the need to use heavy fuel oil, as the new boiler plant will use natural gas as its main fuel source.”
— Webster & Horsfall
“What we hadn’t expected initially though is the level of control the new system provides us with; it’s amazing. It alerts us to any potential issues, is easy to maintain (no annual statutory inspection is required) and is quick to respond. All that and it doesn’t take up much room.”
— Peter Connolly, Production Engineer at Vacu-Lug
“The ESM 2000 installation, together with an ongoing programme of process plant lagging and steam trap maintenance, has enabled us to significantly reduce our gas usage and cushion the company against rising gas prices.”
— Dave Scrivens, Facilities Manager at Plastic Omnium
“Babcock Wanson’s expertise and ability to provide a whole package made them the leading contender for this project. On further investigation, their proposal was also commercially viable, which sealed the deal.”
— Denis Kelly, Engineering & Construction Manager at Stolthaven Dagenham
“The Thermal Fluid Heaters themselves were ideal for this project as they are based on mature technology and are well proven in the field. They are robust and also require very little maintenance.”
— Ian McQuarrie, Engineering Manager at Puredrive
“During my three years here, the Steam Generators and Thermal Fluid Heaters have worked flawlessly. Babcock Wanson carries a good name in the business for both quality and equipment longevity. Their knowledge, company wide, is exceptional and the whole package from installation through to service is managed professionally.”
— Jason Hall, J&A Young Engineering Manager
“We had estimated our steam requirements, but Babcock Wanson had the experience to understand that we had underestimated this. In fact, the erratic nature of the steam loads would have been impossible to meet under our existing spec. Babcock Wanson was able to identify this as well as provide a very energy efficient solution with a number of enhanced features”.
— Lee Bullen, Corrugated Services Manager at Board24
“It’s running very well, both easy to use and efficient. The service from Babcock Wanson has also been very good.”
— Peter Shrimpton, Engineering Projects Manager at Bridgnorth Aluminium Ltd
"We were unfamiliar with Babcock Wanson, but we’ve had no problems with it whatsoever; you simply switch it on and it works – simple as that! The service we have received from Babcock Wanson has also been great.”
