Amarinth awarded Technology Strategy Board grant to develop energy efficient centrifugal molten sulphur pump

Amarinth, a leading company specialising in the design, application and manufacture of centrifugal pumps and associated equipment to the Oil & Gas, petrochemical, chemical and industrial markets, has been awarded a £250,000 grant from the UK’s innovation agency, the Technology Strategy Board to invest in the further development of a design and production process to produce highly energy efficient pumps and leverage this work to launch an energy efficient molten sulphur pump for the petro-chemical industry.

Amarinth has been working for some time on developing a cost effective and rapid process for the design and manufacture of bespoke best efficiency point (BEP) optimised impellers that can be produced on short lead times and at an acceptable commercial cost for use in industrial pumping applications. The centrifugal pumps used throughout industry are often a ‘best fit’ selection for a given application from a standard range of pumps and the majority of pumps in use today do not run at their BEP and energy inefficiencies of up to 25% can often be found.

In an ideal world the impeller and casing of a pump would be designed and manufactured to each specific pump requirement (or customer’s duty). Being able to manufacture pumps designed to operate at their BEP can offer end-users between 10 and 25% in energy savings. When 95% of pump life cycle costs are energy costs this represents a huge saving and a significant reduction in CO2.

Work undertaken by Amarinth to date has proven that being able to provide optimised impellers will reduce annual CO2 emissions in the company’s target market by 17,000 tonnes by 2020 and 110,000 tonnes by 2050.

Amarinth will use the £250,000 Technology Strategy Board grant, the maximum funding that can be awarded, to further its development of the design and production processes to deliver the most advanced and efficient bespoke centrifugal pumps on shorter lead times at a commercially acceptable cost. The first application of this work will be an energy efficient centrifugal pump for the sulphur production market with high efficiency, high maintainability and high reliability which the company anticipates it will launch in 2014.

The pumping of molten sulphur in the petro-chemical industry is a particularly aggressive environment requiring high reliability and robustness as the molten sulphur is maintained at temperatures of between 127C and 147C. Significant increases in energy efficiency are now being demanded by the operators and Amarinth identified this new application as an ideal focus around which to launch its work on bespoke BEP optimised impellers.

Following the successful introduction of the molten sulphur pump, Amarinth will apply the proven design and rapid tooling techniques to many of its other pump ranges in order to deliver higher efficiency pumps on short lead-time to the Oil & Gas and Petrochemical markets.

Oliver Brigginshaw, Managing Director at Amarinth, commented: “We have been working on this project for some time, initially with assistance from the Carbon Trust until the government curtailed that funding. We are delighted that the Technology Strategy Board has now seen the enormous benefits that can be attained from our work and we are looking forward to its first commercial application with the launch of our molten sulphur pump in 2014.”

Amarinth Pump Manufacturing

Amarinth is a carbon net zero organisation delivering world-leading expertise in the design, application and manufacture of centrifugal pumps and associated equipment for critical applications in many of the most arduous and hostile environments around the globe.

Founded in 2002, Amarinth has harnessed the skills, creativity and passion of people who have worked in the pump industry for decades, delivering bespoke API and ISO pumps primarily to the offshore and onshore oil & gas industries; nuclear and renewable energy generation; defence; desalination; process and industrial markets.

The company’s innovative approach, business agility and use of sophisticated computer applications enables it to deliver robust, reliable and sustainable pumping solutions on the shortest lead times in the industry.

Process pumps – API 610, API 685, ISO 5199 horizontal, vertical and in-line bespoke process pumps, including ones that are hydraulically and dimensionally interchangeable with the former Girdlestone and other obsolete pumps.

Skid packages and modules – Supplied with a variety of drives for applications including de-sanding, mixing, filtration and chemical injection and tailored for the oil & gas, water treatment and power generation industries.

Condensate recovery – Cutting-edge design providing low NPSH up to 98°C with variable speed drives to reduce cycle time and lower operating costs, available in stainless steel, galvanised or copper tanks for light or heavy industrial uses.

Seal support – Integrated pressurised and vented seal support systems designed and delivered to API 682 and ISO 5199 standards and specific site specifications and requirements, working closely with AES, Eagle Burgmann, John Crane and Protect System.

Spare parts – Critical spares for all Amarinth pumps and related components can be dispatched the same day, reducing potential downtime, and in addition components for the former Girdlestone and other obsolete pumps can be re-engineered often improving the performance of existing assets.

Services – A full range of pump related services, delivered from UK head office or on-site globally, onshore or off-shore, including full commissioning and start-up support; also strip, report and refurbishment of any pump regardless of manufacturer.

Amarinth operates globally from its base in Rendlesham Suffolk, United Kingdom and offices in the Middle East and Malaysia with a global customer base, including BP, Shell, ADNOC, NOV, ExxonMobil, Schlumberger, COSCO, EDF, GlaxoSmithKline, Saudi Aramco, Pfizer, Diageo, Kuwait Oil Company, AMEC, Fluor, LUKOIL, Halliburton, and Babcock.
