Fresh gasification advances delivered

Jon Lawson

A leading manufacturer of high-performance filtration and separation technology has secured spares orders worth US$5 million for Asia’s largest gasification projects.

Porvair Filtration Group began working with South Korea’s POSCO E&C in 2011, and India’s Reliance Industries Ltd in 2013, providing advanced char filtration systems to both.

Porvair has now supplied performance-enhancing operational spares that are expected to be employed by Reliance and POSCO on-site in the near future, further heightening efficiency through durability, extension of operating life, and lowered costs.

The filtration specialist is leading innovations in gasification and sees its work with POSCO and Reliance as a demonstration of what can be achieved in the production of synthetic natural gas (SNG) with products encompassing a range of high temperature filter elements and pulse jet blowdown systems.

POSCO E&C, a division of multinational steel manufacturer POSCO, is building a coal gasification plant to produce SNG for powering its Gwangyang facility. The plant will incorporate Porvair’s hot gas filtration system – an established technology used to remove fly ash during the gasification process.

In 2011, Porvair successfully completed delivery of its initial POSCO contract, valued at in excess of US$10 million – the first CB&I E-Gas project outside of the USA – providing critical filtration of the syngas downstream of the gasifier and heat exchanger to remove the erosive and abrasive char that damages downstream equipment and processes.

Following on from that success, India's largest private sector enterprise, Reliance Industries Limited, selected Porvair to design and build char filtration systems for its new pet coke gasification plant at Jamnagar, as part of the J3 expansion project.

Reliance's Jamnagar site is the largest oil refining complex in the world, with an aggregate refining capacity of 1.3 million barrels of oil per day.

The gasification facility – also the largest of its kind built in the world – is set to process petroleum coke and coal into synthesis gas using E-Gas technology licensed from Lummus Technology, the technology group of CB&I.
