Life-cycle model assesses petrochemical technology. M.I. Sokic. Hydrocarbon Processing, July 1994, 73(7), 77--81.

A mathematical model using life-cycle criteria is used to evaluate the efficiencies of petrochemical processes. Relations between performance, efficiency, and economic are described and illustrated. The model considers raw material and energy usage, and the efficiency of technology, waste treatment and hazard protection. Short and long-term improvements in efficiency are suggested. The recommended model is described in mathematical terms and its application is discussed. It has flexibility to adapt to changing supply and demand, changing processing capacities, and the introduction of new technology. 7 refs.
