Petroleum refineries generate power from a number of sources, including cogeneration plants and steam networks. Generally, steam networks use turbines to improve operational reliability, specifically as drivers for rotating equipment. Due to increasing energy costs, it is essential to maximize the power-generation capabilities of steam networks. This article presents a spreadsheet-based optimization model...

One of the chemical process industries’ (CPI) foremost authorities on process safety, Trevor Kletz, passed away in late October at the age of 91. Amongst Kletz’s many achievements, one that stands out is his extensive contributions to the concept of inherent safety — a technique to reduce plant hazards through design, for example by keeping a lower inventory of hazardous chemicals on hand...

Capital cost calculations I recently read the article “Capital Costs Quickly Calculated” [ Chem. Eng., pp.46­–52, April 2009] and find it extremely informative and useful. I have reservations about the example given about the cost comparison of two spherical storage tanks. The authors state that the costs of spherical storage tanks are proportional to surface area, therefore, to the...

Gear units play a critical role in a diverse array of chemical process industries (CPI) facilities, to match the speed of a selected driver with the speed of the driven equipment. Today, they are used extensively in pumps, turbines and compressors, in material-handling units (such as conveyers and stackers), and in other equipment, including mixers, kneaders and extruders. This article discusses...

Ethanol is widely produced by fermentation of sugars from agriculture feedstocks, such as corn and sugarcane. In order to meet growing energy requirements, several lines of research have focused on cellulosic ethanol production, where some type of lignocellulosic biomass, such as woodchips, sugarcane bagasse, corn stover and others, serve as the feedstock for the process. Use of these raw materials is...

Calculating volumes of solids in piles as they are poured into various shaped containers can be important information for solids-handling applications. The following set of equations represents guidance to help determine solids volume in these cases. Solids in containers Solids fed through a nozzle into a cylindrical or rectangular silo normally form a partial cone of a complex shape when the material is...

Working in close proximity to the high pressures and temperatures commonly found in the chemical process industries (CPI) is cause enough for concern over a person’s wellbeing; but working in close proximity to chemicals that are considered toxic, hazardous or reactive escalates that concern to a higher degree (Figures 1 and 2). The dangers of such chemicals underline the paramount importance of...
