Abstract

Abstract: The effect of pressure on product distribution was investigated in a FCC pilot plant. The base-energy consumption of a FCC unit and the overall economic benefits without one-off investment was calculated based on the product distribution and the actual price system in 2015. It reveals that increasing reaction pressure causes the lower gasoline yield and base-energy consumption and lower octane number. As the pressure increases from 0.125 MPa to 0.247 MPa, the gasoline yield and the base-energy consumption decreases by 2.4 percent points and 245 MJ/t，respectively, and the overall economic benefit falls 147 RMB/t.

Key words: FCC, pressure, product distribution, base-energy consumption
