The topic of carrying out process engineering calculations in the most effective manner can be considered in these four ways: 1. The purpose of the calculation 2. The content of the calculation 3. The method used to carry out the calculation 4. The performer of the calculation   The purpose of the calculation Engineers typically carry out calculations for a variety of purposes including the following...

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...

Industrial microbiology continues to hold the promise of producing an increasingly large array of commercially important chemicals because an ever-wider number of useful microbes is being developed and successfully deployed at commercially viable scales. Today, many of these bio-based chemicals are needed in quantities so large that existing fermentation technology is inadequate, and this is pushing the...

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...

Milling is a mechanistically driven process that breaks solid material into smaller pieces. Selection of the optimal mill is a daunting task that often leaves engineers relying on vendor suggestions to decide which mill is right for their job. This article addresses a methodology to score and rank the various mills for use with a particular material. In milling, a materials are broken up due to a few basic...

Chemical, pharmaceutical and related industries produce large amounts of wastewater in their production and cleaning processes. The wastewater characteristics are often diverse, and may include minimally biodegradable or toxic substances, or both. To protect the environment, these wastewaters typically must be treated to minimize pollutant concentrations before discharging to the environment, or to...

Boilers generate steam using different methods to circulate the steam-water mixture through the evaporator tubes. These methods include natural circulation (Figures 1, 2a–2c), forced circulation (Figure 3a), and a once-through design. Figures 3b, 4 and 5 show examples of a waste-heat water tube and fire-tube boilers with external downcomers and risers. Most boiler systems have evaporator tubes heated...

Distillation and absorption are back. The AIChE Spring Meeting (San Antonio, April 28–May 2) proved it and the fall meeting to be held in November will muffle any doubting Thomases. During the late 1970s and early 1980s, I spent appreciable time on acid-gas absorption. I knew the amine and hot-potassium-carbonate processes fairly well. I remember giving an absorption presentation at a large Canadian...

Where will you be on September 25 and 26? The Chemical Engineering staff will be in Galveston, Texas at the ChemInnovations Conference and Expo. We hope you will be too. Four years ago, we had the idea to start a conference and tradeshow dedicated to the chemical process industries (CPI). That idea materialized, rather quickly that first year, into the annual event that has been held in Houston, New...
