The authors have developed a new safety instrumented system (SIS) evaluation method based on reliability analysis. It evaluates the Safety Integrity Level (SIL) using Fault Tree Analysis (FTA). When the SIL falls short of the system's target level, t

This study introduces a method that selects equipment, so as to reach the required unavailability level, by carrying out an optimization analysis which considers the reliability data and cost of the equipment. A more practical optimization problem ha

Several operational modes can be used in the operation of utility plants for petrochemical plants. For the optimization system of a utility plant to be effective, all the possible operational modes should be taken into account. Moreover, due to the v

Effects of microwaves on catalytic reaction systems are analyzed theoretically in this work. Use of microwaves is encouraged to save energy. The effects of microwave heating are analyzed theoretically by assuming that the catalyst pellet is homogeneo

A short-cut method is proposed to evaluate the performance of pressure swing adsorption (PSA) systems. The basic steps in PSA systems are categorized into the adsorption and desorption steps. Each step is mathematically modeled under the assumption o

This paper extends the authors' numerical algorithm for solving nonlinear index problems. The extension permits the solving of a special class of near index problems whose ill-conditioned behavior produces one or more small but nonzero pivots when at
