Process variation reduces a pipeline’s maximum attainable frequency by creating unbalance in the stage delays. As a result, the pipeline ends up cycling with a period close to that of the slowest pipeline stage. ReCycle was proposed in ISCA 2007 as a framework for comprehensively applying cycle time stealing to balance the stage delays under process variation, thereby allowing the pipeline to c...

The application of process control automation software for the recycle of peroxide bleaching rinse water to fabric scouring on a continuous preparation range is presented. Analytical data taken on wastewater samples document operating conditions of the preparation range and the quality of the recycle water. An economic analysis of the recycle process and the cost of range modifications to insta...

This paper presents the retrofit of five conventional distillation trains for the separation of quaternary mixtures of hydrocarbons for feed compositions with high or low content of intermediate components. The retrofit implies the incorporation of liquid or vapour recycle streams among the conventional distillation columns. Each recycle stream removes one condenser or one reboiler. The introdu...

Synthetic juice clarification was done through spiral wound ultrafiltration (UF) membrane module. Synthetic juice was clarified at two different operating conditions, such as, with and without permeates recycle at turbulent flow regime. The performance of spiral wound ultrafiltration membrane was analyzed during clarification of synthetic juice. Synthetic juice was the mixture of deionized wate...

Nowadays, the increase in consumption and shortening of life cycle products significantly amount waste generated, causing serious environmental problems. As a result, management has become one most important tasks 21st century, which puts huge burden on economy. Waste means practical implementation protection environment from harmful effects entire waste. This is process that involves preventio...

on waste can alter the optimum transition path. In the optima with recycle, the lower waste penalty from reduced buildup of 239Pu more than compensates for the separations and fuel fabrication facility costs. Figure 3 shows this buildup for each of the runs. However, with a high repository discount (run 3) recycle technology is unable to compete with cheap direct disposal. The optimum in run 4 ...
