Leigh Creek Energy (LCK) has entered the final stages of its Pre-Commercial Demonstration (PCD) project, edging closer to producing commercial synthesis gas (syngas).
With the gasifier initiated in October at the former coalfield site, gas flow has been continuing for more than 50 days, currently in the pyrolysis phase.
Pyrolysis is the stage between the initiation and commercial syngas, with gas temperatures reaching 300 to 800 degrees.
Commercial syngas flow is produced once the temperature reaches above 1000 degrees, which LCK hopes to achieve by the end of the year.
LCK Managing Director Phil Staveley said the PCD is developing as expected.
”LCK’s on-site Operations Team and Adelaide-based technical experts continue to manage the development of the PCD gasification chamber toward commercial flow rates, by managing the gasifier’s operating parameters, such as pressure, water inflow and outflow rates,” he said.
“This process is continuing and importantly has not stopped since the gasifier was initiated on October 10, 2018.
“Through this we continue to work closely with the regulator to ensure appropriate oversight.”
The company has plans to upgrade a portion of its 2964 petajoules of 2C syngas to proven and probable reserve status at the start of 2019.
LCK recently announced syngas produced at the former coalfield site would be used to manufacture fertiliser products.
Syngas produced through in-situ gasification (ISG) can be refined into ammonia, which is used in fertiliser and industrial explosives.
The PCD acts as a trial for a potential commercial ISG facility in Leigh Creek.
