Techno-Economic Assessment of Pulp Mill Infrastructure Integration with the Alcohol-to-Jet Pathway for Aviation Fuel Production

Presenter: Scott Geleynse, Washington State University

Can the production of sustainable alternative jet fuel be integrated into existing pulp mill infrastructures – and at what cost? This presentation will dig deep into an investigative study that compared strategies for the integration of Alcohol-to-Jet (ATJ) conversion with kraft pulp mill infrastructures. 

Alcohol-to-Jet is a pathway for production of aviation fuel through the catalytic conversion of alcohol to synthetic paraffinic kerosene, which is a sustainable alternative jet fuel (SAJF). ATJ Synthetic Paraffinic Kerosene (ATJ-SPK) is now qualified for commercial use in the United States, and the aviation industry has demonstrated considerable interest in greater adoption.

In the study, process integration engineering was used to identify key barriers, opportunities, and research areas. Integration cases included the use of pretreatment and hydrolysis of cellulose in pulp intermediates as well as hemicellulose utilization through pre-extraction or black liquor fractionation. The effects of these changes on the mass and energy balances of the plant were considered, along with capital cost estimations of new process units.

What you will learn

In this discussion, techno-economic-analysis models will be used to predict project costs and discuss opportunities for reducing the cost of producing liquid fuels, including SAJF, in a completely or partially retrofitted pulp mill using the ATJ pathway.
