Reducing safety risks
Coal seam gas wells release gas through groundwater extraction. The extracted water and gas is diverted to the surface where the water is separated from the gas. The coal seam gas water has a high concentration of salt, it is collected and transferred via pipelines to storage ponds.
The water is then pumped to water treatment plants where it is further treated prior to being used for agriculture, municipal or industrial applications. The coal seam gas water treatment plant is powered by gas engine generators using methane from the gas fields.
Meeting global safety standards for fire and gas is a key priority for the energy company. As such, they called on PSA Engineering, a Process Safety Partner in the Rockwell Automation PartnerNetwork™ program, to upgrade the emergency shutdown and fire and gas system, across their seven generators. Based in Ormeau, Queensland, PSA Engineering provides a wide range of specialist engineering services for both control and safety instrumented systems across a variety of industrial sectors.
“With a treatment capacity of more than 90,000 cubic meters per day, reducing safety risks was a critical consideration for the water treatment plant. The key driver for the project was to replace a non-compliant SIL2 fire and gas system with one that complied,” said John Teahan, lead I+E engineer at PSA Engineering responsible for the delivery of a fully compliant OLF-070 SIL 2 F+G Safety Instrumented System.
