EPA finalizes GHG permit for $1B gas-to-gasoline plant in Texas; 8M barrels per year
October 03, 2014
The US Environmental Protection Agency (EPA) has issued a final greenhouse gas (GHG) Prevention of Significant Deterioration (PSD) construction permit to Natgasoline LLC to construct a new motor-grade gasoline production facility in Texas that uses natural gas as feedstock (gas-to-gasoline, or GtG).
Natgasoline is a new wholly owned greenfield methanol production complex being developed by OCI N.V. The proposed new GtG facility will comprise two main process operations: a methanol plant with a capacity of almost 1.75 million metric tons of methanol per year, and the methanol-to-gasoline plant (MTG), which will produce more than 8 million barrels of gasoline per year. The methanol plant will use natural gas delivered by pipeline as feedstock; the MTG plant will primarily use methanol from the methanol unit, but can also process methanol from other manufacturers.

Researchers in South Korea are suggesting two new carbon-dioxide-utilized Gas-to-Liquids processes (CUGP) to increase the overall efficiency of conventional Fischer-Tropsch GTL. In a paper in the ACS journal Environmental Science & Technology, they report that the two CUGP options increase carbon efficiency by 21.1−41.3% and thermal efficiency by 15.7−40.7%, with total CO2 emissions reduced by 82.0−88.4%, compared to different conventional F-T processes.
This results in a decrease in total CO2 emissions to less than 5g CO2/MJ F-T product, compared to a range of 27.0 to 36.2g CO2/MJ F-T product for the conventional processes.

A team from Sasol Synfuels, Jacobs Consultancy and Argonne National Laboratory has used results from a US industry-wide linear programming (LP) modeling study of individual US refineries to examine the impacts of a number of significant and looming changes—such as shifts in refinery crude slates; regional and seasonal variation; gasoline/diesel (G/D) production ratio; and GTL diesel blending—on US refinery, unit, and product efficiencies. (LP is the the primary tool for analysis and optimization in the refining industry.)
Results of their study, which appear in the ACS journal Environmental Science & Technology, suggest that refinery and product-specific efficiency values are sensitive to crude quality; seasonal and regional factors; and refinery configuration and complexity—which in turn are determined by final fuel specification requirements and regulations. Additional processing of domestically sourced tight light oil could marginally increase refinery efficiency, but these benefits could be offset by crude rebalancing, they found.

Researchers develop new lower-temperature process for conversion of natural gas alkanes to alcohols
March 14, 2014
Researchers from The Scripps Research Institute (TSRI) and Brigham Young University have devised a new and more efficient method to convert natural gas into liquid products at much lower temperatures than conventional methods.
Their work, reported in the journal Science, uses main-group metals such as thallium and lead to oxidize methane and the other alkanes contained in natural gas (ethane and propane) to liquid alcohols at about 180 °C instead of the more than 500 °C used in current processes, said SRI Professor Roy Periana, who led the research. This creates the potential to produce fuels and chemicals at much lower cost.

Primus Green Energy’s STG+ patent for liquid fuel synthesis from syngas approved
February 05, 2014
Primus Green Energy Inc., an alternative fuel company that converts natural gas and other feedstocks directly into drop-in transportation fuels and solvents (earlier post), announced that its patent application covering its STG+ liquid fuel synthesis technology has been allowed by the US Patent and Trademark Office (USPTO). STG+ produces high-quality, cost-effective, drop-in liquid transportation fuels directly from syngas derived from natural gas and other carbon-rich feedstocks in a single-loop process.
STG+ essentially improves upon commercial methanol synthesis processes and ExxonMobil’s methanol-to-gasoline (MTG) process, combining them into an integrated, optimized system that efficiently converts syngas directly to fuels. In addition to the gasoline product, the STG+ process can also produce jet fuel, diesel and high-value chemicals by changing the catalysts and operating conditions. The company, which is currently producing synthetic gasoline at its demonstration plant (earlier post), plans to build several more reactors in parallel to the current production train for other fuel products.
