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...

Polypropylene (PP) is a thermoplastic polymer formed by the polymerization of 10,000–20,000 monomers of propylene. With a global market of about 60 million metric tons per year, PP is the second most-used polymer globally. More than 35% of the world’s total PP is produced using LyondellBasell’s (Houston; Spheripol technology. The process In Spheripol technology...

Chemical processing equipment made from thermoplastics can have distinct advantages for equipment corrosion, fluid contamination and flame retardancy. When purchased in the form of heavy-gauge sheets, these thermoplastics can be machined, fabricated and formed into a virtually unlimited variety of process equipment components that may address chemical processing challenges that other materials cannot. The...

Rotary equipment, such as centrifugal pumps, often represent the heart of plants in the chemical process industries (CPI). A critical factor in the longterm reliability of such equipment is a high-quality design and commissioning process, so that initially, the rotary equipment will have the maximum built-in strength to survive upset operating conditions, yet not be overdesigned in a way that leads to...

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 management of process plants requires understanding and applying the fundamental tenets of safe design, construction and operation of facilities. This overview summarizes best practices that have been developed to ensure the safest possible use of DP:DPO (diphenyl–diphenyl oxide) eutectic heat-transfer fluids. A review of the concepts necessary for effectively maintaining a leak-tight...

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...
