Abstract

Crude oil blending significantly impacts energy consumption from heating furnaces during crude oil processing. Furnace energy consumption from burning fuels such as natural gas, fuel oil, or propane causes huge amounts of CO₂ emissions.

Authors develop a methodology framework for crude oil blending and processing with simultaneous consideration of energy, emission, and economic profit (E3).

It includes four stages of work: steady-state modeling, heating energy consumption calculation, emission model development, and economic evaluation. Using Aspen HYSYS simulation, the methodology provides a quantitative support for a refinery to identify an optimal E3 operating strategy. A case study demonstrates the efficacy of this methodology.
