Piping represents a major cost for projects in the chemical process industries (CPI). Larger pipe diameters increase upfront capital costs for a project, but the lower pressure drops afforded by large pipes mean less power is required to move the fluid through the pipe. Optimizing pipe diameter becomes an exercise in balancing the capital cost savings realized by using smaller pipes with the power required...

A chemical executive once noted that his firm derives one-third of its income from products that are less than ten years old. Indeed, existing companies thrive and new ones proliferate through innovation and product improvement. They depend on scientists and engineers working "in the trenches" or "at the bench" to drive development. Yet, most potential innovations never succeed...

  At the beginning of 2008, it’s clear that global economic growth is slowing. The housing downturn has adversely affected the U.S., and the ensuing credit problems (and tightening) have spread to other nations. A key issue is whether or not the weakness has done enough damage to tip the economy toward recession. The general consensus is that it is likely that the U.S. will avoid a downturn but...

The globalization of the economy is making the world a smaller place and leading businesses — the chemical process industries (CPI) included — to source, produce and sell material in foreign lands. Politics aside, the trend has the potential to wreak havoc on the supply chain, logistics and transportation operations of chemical corporations unless strategies that increase collaboration and...

    Free trade agreements, global manufacturing standards and the Internet have made it possible for companies to do business in countries they would not have considered 20 years ago. Open is a world of opportunity, but for processors of pharmaceuticals, semiconductors and other materials that must meet high standards of product purity and performance, the competition is stiffer than ever as...

This fall, Asahi Chemical Industry Co., Ltd. (Tokyo; edlinks.che.com/6516-541), plans to start up a 70,000-m.t./yr plant for producing acrylonitrile (AN) at its 100% subsidiary Tongsuh Petrochemical Corporation Ltd., (Ulsan, South Korea). The plant will be a renovation of an existing facility, which made AN using the conventional propylene-based (ammoxidation) process, into one that uses...

    If your estimate for a project's capital cost is too high or too low, incomplete or wrong, a poorly developed scope is the mostly likely cause. In almost all cases, project cost estimating is more accurate than the scope used to develop the estimate. (To develop a good project scope, please refer to "Get Your Scope Straight for Project Success," CE, February, pp. 36-38). Yet good...

    Typical process utilities include electricity, process steam, refrigerants, compressed air, cooling water, heated water, hot oil, process water, demineralized water, municipal water, and river, lake, or ocean water. For preliminary cost estimates, waste disposal cost can also be treated like a utility expense. Unlike capital, labor, and other expenses, utility prices do not correlate simply...

    Engineers often need to predict the cost of piping and pipefitting associated with a process unit. Even though detailed prices are available, finding and organizing them takes time and costs money. For those needing a quick method of approximation (such as for a pre-design estimate), a short-cut piping cost method is presented in this article. For convenience and compactness, the relevant...

Axxom Software AG (Munich, Germany; edlinks.che.com/5827-541) has introduced a new technological approach that, for the first time, allows an end-to-end supply chain optimization of very large, multi-stage networks. Based on the so-called cost-scaling algorithms (CS-A), production companies can now plan very complex...

    The first two installments of this three-part series (CE, November 2005, pp. 40–45, and December, pp. 42–47) dealt mainly with the major methods for estimating the capital costs of pilot plants. This final installment begins with a look at the making of provision for contingency, a concept sometimes misunderstood and even more often misapplied in pilot-plant cost estimating...
