Click here for full pdf version of this article - includes all graphs, charts, tables, and author information The use of safety standards, particularly IEC 61508 [1] and IEC 61511 [2], has increased rapidly in the past several years. Along with the adoption of these standards has come an increase in the need for accurate reliability data for devices used in safety instrumented systems (SIS), both...

    Gone are the days of one-size-fits-all engineering software packages. Today, solution providers offer versions with improved integration for advanced data sharing and simplified user interfaces with the ability to multitask between the design house and the plant floor, bringing the power of engineering software to everyone from trained experts to software novices who just want to run a few...

    In multicomponent systems, equation-of-state (EOS) methods generally do a good job of determining vapor-phase properties. But accurate determination of properties for the liquid phase is much more difficult, especially when the liquid contains dissimilar molecules, polar molecules such as alcohols and glycols, or acid gasses such as H2S and CO2.   In this article, a multicomponent system...

    Process performance, quality and reliability depend directly on how a plant performs in real time. Yet many plants track and respond only to longterm averages. By measuring and responding to realtime measures, you can ensure:     Quick recovery from process upsets   Fast change-over to another product   Shortened batch-cycle times   Measuring and responding to the...

    Spreadsheets have been around almost as long as personal computers. While early versions were clumsy and limited in scope, today’s spreadsheet programs can do almost anything the user wants them to do. These broadened capabilities are made easier through the use of internal (built-in) functions, add-in programs and the use of macro programming. In this article, we explore how...

    A detailed follow up of the cations present in the wastewater of the Monsanto Europe site in Antwerp, Belgium, has led to an increased understanding of changing wastewater treatment plant performance. The chemical process industries' (CPI) other wastewater treatment plants that handle continuously changing mixtures of different manufacturing plant effluents should also consider routine...

It's a simple matter of fact: a chemical process plant operates by the products and services of numerous - and, unavoidably, competing - vendors. Since the resulting compatibility issues only hamper productivity, vendors, EPC firms and owner/operators alike tried to put their differences aside to address interoperability, at this year's DaratechPlant (Houston; January 29-31; daratech.com). Standardization...

Until now, creating a set of "as-built" plant drawings meant either laser-scanning the outline of an entire piping system, or measuring all the components manually. By paring Leica Geosystem's in-field-to-model laser technology with Coade's CADWorx Plant Design Suite, Coade, Inc. (Houston, Tex.; edlinks.che.com/6893-534) has reduced the time required by more than 50%, says Vornel Walker, Coade's manager...

Despite successful completion of major engineering objectives, the deadlines of project milestones are often missed by weeks or even months while the supporting, official-document packages are being assembled. These costly delays can be avoided with Sword Inc.'s (edlinks.che.com/6893-535) C2Share, launched at daratech Plant 2007 Conference (both Houston). An add-on application to SharePoint...

For the first time, it is possible to gain a detailed quantitative insight into the internal operation of multitubular reactors — complicated units that can be notoriously difficult to design because they involve complex catalytic reactions, a large number (often 2,0000 or more) of tubes, and closely coupled, shell-side heat transfer and hydrodynamics, says Mark Matzopoulos, marketing director at...

    The equilibrium phase distribution ratio (K value) is necessary for designing and assessing the performance of distillation columns. This paper proposes a simplified approach to calculate the K value that is suitable for preliminary design work and for checking the performance of existing columns. The article also explains the first principles for calculation of K values from the fugacity of...
