摘 要: | 在中型提升管催化裂化试验装置上,考察了反应压力对产品分布的影响;根据不同压力下的产品分布,基于2015年实际价格体系,计算了催化裂化装置的基准能耗及不考虑一次性投资情况下的综合经济效益,分析反应压力对装置基准能耗及综合经济效益的影响。结果表明:随着反应压力的提高,汽油收率下降、辛烷值降低,基准能耗和综合经济效益均下降;当反应压力从0.125MPa提高至0.247MPa时,汽油收率降低2.4百分点,基准能耗下降245 MJ/t,综合经济效益下降147元/t。

EFFECT OF PRESSURE ON PRODUCTION DISTRIBUTION AND ENERGY CONSUMPTION OF FCC UNITS |
| |
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. |

Keywords: | FCC pressure product distribution base-energy consumption |
