摘要

The Honeywell chemical plant located in Hopewell, Virginia includes processing units that purify raw phenol, react the phenol with hydrogen to form crude cyclohexanone, and purify the crude cyclohexanone. In order to reduce energy usage, two opportunities for heat recovery and heat integration were identified. A feasibility study and economic analysis were performed on the two opportunities, and both projects were implemented. The first project utilized the heat contained in a distillation process overheads stream to preheat the raw material entering the distillation process. This was accomplished via a heat exchanger, and reduced the utility steam requirement by 10,000 pph. The second project utilized the heat generated by the hydrogenation reaction (in the form of waste heat steam) to preheat the feed material in an adjacent process. This was accomplished via a heat exchanger, and reduced the utility steam requirement by 8,000 pph. These two energy projects required $1.1 million of capital and saved $1.0 million in utility steam annually.
