Ube Industries, Ltd. (UBE; www. ube-ind.co.jp) and HighChem Co. (both Tokyo; www.highchem.co.jp) will license their technologies for transforming coal-derived synthesis gas (syngas) into manufacturing ethylene glycol (MEG) — a polyester feedstock — to Qianxixian Qianxi Coal Chemical Investment Co. (Guizhou, Qianxixian, China). The license covers a process...

A new method for removing hydrogen sulfide from natural gas at ambient temperatures could allow significant energy savings compared to the current technique and increase the range of H2S concentrations in natural gas that are economically viable to extract from sour gas wells. In conventional sour-gas scrubbing, aqueous solutions of alkanolamines are used to selectively absorb H2S, but due to water’s...

By the end of this year, Asahi Kasei Chemicals Corp. (Tokyo; www.asahi-kasei.co.jp) plans to complete development on two processes that utilize excess C2 and C4 fractions for producing propylene and butadiene, and if all goes smoothly, implement them by March 2012. The company has been developing its so-called E-Flex (for producing propylene) and BB-Flex (for producing butadiene) processes, and is now...

  Recycling copper Steinert Elektromagnetbau GmbH (Cologne, Germany; www.steinert.de) has recently installed its first XSS-F unit — said to be the worlds first inline system designed to extract copper from shredded ferrous scrap. Installed at a German recycling yard, the system is capable of processing high volumes of steel scrap directly out of the shredder. The new sorting system features a...

Regulatory authorities around the world require continuous emissions monitoring of certain pollutants from large combustion sources. There are two main technologies for monitoring these emissions on a continuous basis — the more traditional one relies on sampling and analyzing exhaust gases from a continuous emissions monitoring system (CEMS); and the newer one relies on software that uses...

Good troubleshooting skills are invaluable in chemical engineering practice. While their value is clearly gleaned from the impact they have on plant performance, it is also a reflection of the intangible process of learning them. Last month, at the AIChE Spring meeting in Chicago, Ruth Sands, former CE author and mass transfer consultant at DuPont Engineering Research & Technology, presented attendees...

Storing solid materials in hoppers, bins and silos is ubiquitous in the chemical process industries (CPI), as are challenges associated with dispensing them. In many cases, using vessels with steep cones and smooth walls is enough to provide reliable flow. However, it is not always feasible to design and install hoppers with the optimal geometry, and many solids have difficult or variable flow properties...

  The chemical process industries (CPI) are looking for ways to decrease and control costs, and mixing operations are not exempt from this belt tightening. But because mixing is vital to most chemical processes, it can’t be eliminated. As a result, processors are clamoring for mixing equipment that provides more functionality so they can perform more tasks with less equipment.  Figure 1...

Protect rotary valves and product with this monitoring system Coperion The RotorCheck system (photo) is based on a monitoring device that detects any metallic contact between the rotor and the housing. This contact may result either from the presence of foreign particles or from a process malfunction, such as a sudden increase in product temperature, which may cause the rotor blades to expand and grate...

The ever important aim of energy efficiency in the chemical process industries (CPI) is brought closer to its target by the practice of energy recovery in heat exchanger networks (HENs). When heat exchangers are designed to work together to exchange heat between hot and cold streams, the required utilities are effectively reduced. The HEN designer usually applies the assumptions of fixed operating...

The Witte Co. This salt-drying system recycles hot exhaust air Among a host of advantages, the bulk salt-dryer system (photo) from this company captures half of its hot exhaust air for recycling, which both reduces energy requirements and cuts the volume of exhausted air. Designed for drying road salt, rock salt, sea salt, food-grade table salt and other salt products, the system combines a vibrating bed...

BASF to explore new production investment in Brazil March 10, 2011 — BASF is exploring opportunities for a new investment in Brazil for the production of acrylic acid, butyl acrylate and superabsorbent polymers (SAP). The feasibility study will be completed in 2011, after which decisions regarding the plants to be built will be made. In preparation, BASF and Braskem S.A., a major chemical company in...

Water systems are common in the chemical process industries (CPI). Mixing, heating, concentrating and evaporating water in these systems will often result in an accumulation of inorganic scale, which can markedly decrease process-system efficiency. Scale inhibitors are chemical substances that, when added to industrial water at very low levels, act to reduce or prevent the formation of scale. Over the past...

Manufacturers of specialty chemicals are routinely required to reduce costs and increase the production of their high-value products. Specifically, competitive pressures from the developing world, increases in raw material costs and volatility in energy costs are putting significant pressure on manufacturers to minimize processing costs and maximize product yields. The economic impact of optimization...

Many individuals and organizations have made important contributions to the creation of inherently safer (IS) products, processes and process plants [1–3]. A brief survey of successful case histories shows that most reported applications relied on only a few of the core IS principles. This paper emphasizes the opportunities presented by three particular — and often-overlooked —...

A variety of factors — including a shift in the median age of workers worldwide and the impending skills shortage due to attrition and early retirements — have created a need to find fast and reliable methods and tools for mapping the technical competencies of professionals in the chemical process industries (CPI). Typically competency-mapping projects in the CPI begin with some form of task or...

Traditionally, most students have learned about chemical reactions in laboratories using test tubes, beakers and flasks. Those who have gone on to discover and develop new products have typically done so using these batchwise techniques. This mind-set has continued through the piloting and scaleup phase, so that today, many chemical products are produced batchwise in large, continuously stirred reactors...

This book examines global patent law as it affects the chemical, biological and pharmaceutical industries. Rather than taking a legal case-study approach, it provides a practical discussion of everyday issues and decisions faced by global patent practitioners in these complex industry segments. Focusing mainly on the patent systems in the U.S., U.K. and Japan, the five-section book effectively summarizes...

M Technique Co. (M Tech; Osaka, Japan; www.m-technique.co.jp) has commercialized the Ulrea SS-300, a scaled up version of the Ulrea SS-11 — a forced thin-film microreactor. With a production capacity nearly ten times higher than its predecessor, the Ulrea SS-300 is suitable for mass production of organic, inorganic and biochemicals as well as for producing micro- and nanoparticles and crystals. The...
