Mixing and blending of bulk solids is a common processing step in many industries. For example, in pharmaceutical manufacturing of solid dosage formulations (tablets or capsules), small amounts of a powdered active drug are carefully blended with excipients, such as sugar, starch, cellulose, lactose and lubricants. With foods, many powder-form consumer products result from custom mixed batches; consider...

Many chemical engineers study or employ distillation trays, gas-liquid separators and spray nozzles. Most of those engineers have studied or employed force balances around liquid droplets suspended in upward-flowing vapor streams. Considering a droplet of size “ d, ” for the droplet to be suspended motionless, the summed forces of drag and buoyancy must equal exactly the force of gravity. At...

Solid and serrated fins (Figure 1) are widely used as heat transfer surfaces in boilers and heaters. The use of finned tubes makes heat exchanger equipment compact. The fluegas pressure drop is also decreased relative to a comparable plain-tube design, resulting in lower operating costs. Fin geometry, such as fin density (fins/in.), fin height and fin thickness, should be selected with care as it impacts...

As an industry sector, bio-based chemicals have seen significant expansion over the past year, with several commercial developments occurring in a group of four-carbon commodity chemicals, including succinic acid, butanols, butadiene and butanediol. While a host of technology-based companies have built new facilities and scaled up production capabilities, others have formed alliances with established...

Propylene has been established as an important part of the global olefins business, trailing only ethylene in terms of volume of product. Because inexpensive natural gas from shale in the U.S. is increasingly used as a feedstock for producing ethylene, lower quantities of three- and four-carbon olefins are available. For this reason, new chemical processes for on-purpose propylene using low-cost raw...

The scaleup of liquid mixing systems does not have to be a mystery. The principles are quite well understood, although knowing which principles apply is not always obvious. Follow this guidance to improve operation. 1. Liquid mixing scaleup. Liquid mixing is the most common use of scaleup methods in chemical engineering. The concept of scaleup is to take small-scale results and predict results in...

Security of SCADA (supervisory control and data acquisition) and other industrial control systems (ICSs) is a complex subject, and one that has received much attention in recent years. While modern industrial control systems use many of the same computers, operating systems and networking components as conventional business networks, the two kinds of networks are managed very differently. As a result, what...

Rotary valves are used almost universally in pneumatic conveying systems. They serve three main functions: 1) to provide a pressure-seal (airlock) between two adjacent processes, 2) to provide solids metering (feeding) and 3) to provide a combination of solids metering and a pressure-seal for feeding solids into a pneumatic conveying system. Rotary valves are common devices for feeding solids into a...

For most engineering-procurement-construction (EPC) projects in the chemical process industries (CPI), the data sheets developed at the beginning of the process provide the “shopping lists” that guide the procurement group on the purchase of equipment, system packages, instruments and more. Data sheets should function as the central document, into which all final result of design or...

There is an emerging crisis brewing for the chemical processing industries (CPI) in many regions of the world. Those regions include China, the world’s manufacturing powerhouse; swaths of the U.S., including large parts of its South; and chunks of Europe. For once, the crisis has nothing to do with energy costs. The emergence of cheap shale gas in the U.S., and the identification of exploitable...
