Enhancing Jet Fuel Production: Cutting Costs and CO2 Emissions of Power-to-Liquid Technology

Article Preview

Abstract:

This work minimises the operational costs of synthetic jet fuel production (C8 – C16 hydrocarbon range) by manipulating five operating parameters of the power-to-liquid (PtL) process. Conservative estimates for variable expenses (90th percentiles of historical costs) and revenues (10th percentiles of prices for revenues) were assumed for optimisation of the simulation in Aspen PlusTM software. The distributions of costs under parametric uncertainty were obtained using the Monte Carlo algorithm. Two optimisation scenarios for cost minimisation were developed. They differ on the assumption that CO2 emitted to air is taxed. An additional optimisation scenario targets the maximization of jet fuel production. In comparison to the non-optimised case, the optimised configurations reduce CO2 emissions between 17 and 19% while decreasing the operating costs of jet fuel production by at least 0.80 – 1.89 € / L (depending on the scenario) with a stochastic probability of 90%, and a probability of 50% of reducing them by 0.93 – 2.09 € / L.
