Qenos

Location: Altona, Vic

Capacity: 21 MW & 88 tonnes of steam/hour.

Commissioned: March 2013

Environmental Benefits: Greenhouse gas emissions reduced by approximately 100,000 tonnes per annum.

The facility, operated and maintained by SEI, includes a Solar Turbine Titan 250 gas turbine package with the latest SoLoNOx combustion technology and Rentech Heat Recovery Steam Generator (HRSG).

Background

Qenos is Australia's sole manufacturer and leading supplier of world class polyethylene and polymers. In tandem with its $195M expansion project Qenos was focused on having a state of the art cogeneration facility at its Altona, Victoria site to provide an energy efficient surety of supply through on site creation of electricity and steam.

At the time of construction the facility was the largest industrial cogeneration plant to be built in Australia in over a decade.

Project Scope

The facility, operated and maintained by SEI, includes a Solar Turbine Titan 250 gas turbine package with the latest SoLoNOx combustion technology and Rentech Heat Recovery Steam Generator (HRSG). The steam generator produces steam by recovering the exhaust heat generated by the gas turbine. The facility has the capacity to produce 21 MW of electricity, improving the customer's carbon footprint and providing greater certainty of electricity supply, and generates up to 88 tonnes of steam per hour. The facility supplies up to 171 GWh of electricity to the site annually with the excess electricity being exported to the grid. All steam generation is used by the plant.

Environmental Benefits

The facility generates electricity at a lower greenhouse gas emissions intensity than the average emissions intensity of generators in the National Electricity Market. Further savings are achieved because all waste heat from the gas turbine is used to produce the steam required by Qenos, removing the need to install separate gas fired boilers. With the facility supplying much of its electricity needs it is estimated that overall greenhouse gas emissions will be reduced by approximately 100,000 tonnes per annum.

The project was awarded the "Best CoGen Project" at the 2012 Energy Efficiency Council Industry Awards.
