A new approach to energy efficient process design

Date of Original Version



The rapidly rising costs of energy and US dependence on foreign oil have prompted renewed interest in energy conservation and stewardship. Energy use in the chemical industries is dominated by the cost of separation, particularly distillation. There are ∼ 40,000 distillation columns in the US that consume ∼ 18% of all of the energy in the manufacturing sector. A discussion covers a new approach to energy efficient process design; the concept of shortest separation lines; finding minimum energy solutions that do not correspond to separation pinch points; identifying correct processing targets for processes with multiple units; and enhancing the teaching and practice of energy efficiency in process design. This is an abstract of a paper presented at the 2006 AIChE Annual Meeting (San Francisco, CA 11/12-17/2006).
