Abstract

The designed process performances should be fulfilled by the selected proven technology. It has a set of allowable gaps which become the criteria for mechanical and process guarantees. They are quantified by temperature, pressure, yield or conversion, product purity, selectivity, mass flow, and flow behaviors. On the other hand, the designed performances are commonly obtained from long-time experiences in the process of technological development. In addition, gaps between designed and operational unit process performances should meet the acceptability criteria. Geometry is one factor that affects them. Nevertheless, the designed performances may not yet consider the detailed geometries for the operational performances. Another factor is the simplification in the designed stage which does not fit the actual process conditions. Therefore, this study intends to disclose the improvement of unit process performance using the computational fluid dynamics (CFD) method by including detailed geometries and actual conditions. The examined performances of unit processes were focused on three actual industrial cases: furnace, sand settling vessel, and boiler burner. Based on the results, improving the operational unit process performance using the CFD method is more attractive, accurate, and comprehensive.
