Linc Energy’s downstream technologies team has had a dynamic quarter with many projects underway.
At the UCG to GTL demonstration facility in Chinchilla a new Fischer Tropsch (FT) catalyst was loaded, conditioned and synthesis gas was introduced from Gasifier 5. The initial run is used to verify the activity and selectivity observed on lab-scale. After an extended period it will be used for catalyst deactivation studies. Early results of these tests match the laboratory expectations. In addition, Linc Energy will use mathematical models to confirm the observed catalyst behaviour and how it relates to the company’s commercial FT technology and reactor design.
Engineering and construction work on further process facility improvements are progressing to schedule with commissioning planned by year end. Improvements include the installation of a gas separator membrane which allows for changes in gas composition to the FT reactor and the installation of a reverse osmosis technology on the water treatment plant.
Synthetic diesel produced from the UCG to GTL demonstration facility in Chinchilla was recently tested for its engine emissions at a certified authority in Australia. Depending on the engine speed and load, the results from the tests indicated that carbon monoxide emissions were reduced by 29 per cent, nitrogen oxide was reduced by 12 per cent and particulate matter emissions were reduced by 73 per cent.
Following the successful demonstration of Linc Energy’s synthetic diesel in the ‘Diesel Dash’ earlier this year, Linc Energy has produced FT product to be processed into synthetic jet A1 fuel. Linc Energy has contracted a USA based company with hydro-processing and fractionating capabilities and the production campaign is already progressing well. The synthesized paraffinic kerosene is intended to be shipped back to Australia, where it will be certified as compliant to the requirements (ASTM D7566) before it is blended with conventional jet fuel components and certified for commercial use. Linc Energy intends to use this jet fuel to fly across Australia in the first quarter of 2012, more information soon!
The downstream technologies program also included the completion of a pre-FEED package for a GTL plant of 5,000 barrels nominal plant capacity. The selected engineering company deliverables were received during the reporting period. These include engineering of a modular design. The deliverables will be used to develop an execution strategy using low cost engineering and fabrication centres. The conclusion from these activities will allow Linc Energy to undertake project investment decisions at various sites across the Company’s resource portfolio.
The team continue to evaluate a number of commercial power opportunities globally and this included engaging with equipment suppliers to establish the most cost effective plant options.
