About this presentation
Motivation:
Focus on environmental aspects in oil refining is not enough ([Szklo 2007], [DOE 2000]).
Energy-efficient processes in oil refining are paramount.
Need for research in this field is a must.
Focus:
What’s up on the future of energy consumption.
Opportunities: I’ll give directions.
Looking at the big picture: Not restricted to separation processes.
Goal:
Attempting to show what one can expect in terms of more energy-efficient refineries.
A vision for the future
According to the API’s Technology Vision 2020: A Technology Vision for the U.S. Petroleum Refining Industry [API 2000] report,
The petroleum industry of the future will be environmentally sound, energy-efficient, safe and simpler to operate. It will be completely automated, operate with minimal inventory, and use processes that are fundamentally well-understood. Over the long term, it will be sustainable, viable, and profitable, with complete synergy between refineries and product consumers.
To improve energy and process efficiency, the industry will strive to use cost-effective technology with lower energy-intensity. Refineries will integrate state-of-the-art technology (e.g., separations, catalysts, sensors and controls, biotechnology) to leapfrog current refinery practice and bring efficiency to new levels.
A simple guide to oil refining
Picture of the oil refinery of the future, if the oil consumption maintains its crazy growth…
Actually, this is a 1876 oil refinery in California.
Energetic issues in an oil refinery [DOE 2000]
Future characteristics of oil refineries in terms of energy use:
Energy use is optimized throughout the refinery complex.
Energy efficiency and process controls are integrated.
Fouling of heat exchangers is essentially eliminated.
Innovative heat exchangers are in place (all helical, vertical, no baffles)
Use of cogeneration in refineries is optimized, and refineries are power producers.
Use of very energy-intensive processes (e.g., distillation, furnaces) is minimized.
Source of heat loss (e.g., in pipes) are easily identified through monitoring.
How?
Identify entirely new technology.
Upgrade existing inefficient technology.
