The chemical process industries (CPI) are, by their very nature, global in scope. While chemical process operators share many common aspects (in terms of the use of chemical engineering unit operations), the location of their operation brings about different requirements when it comes to managing gaseous and particulate pollutants, because different countries have different regulations with regard to air...

Compressible gas flow with significant variation in density along pipes is commonplace in the chemical processing industries (CPI). In designing these pipes for compressible flow, it is important to calculate the pressure loss or maximum gas-handling capacity for safety and economic reasons. Due to the complexity of the equations for compressible flow, which often require time-consuming iterations, current...

Would you like to make a quick mental calculation to determine approximate flowrate, velocity, or pipe and duct sizes for many common situations? This article presents two methods for estimating flow characteristics without the aid of charts, tables, calculators or software programs. One method applies to liquid flow in pipes, and the other to air flow in ducts. The techniques are intended to be simple...

Beginning with the early days of automated multivariable control in the 1980s, the trend has always been toward the use of larger matrices and more models. Today’s multivariable controllers commonly comprise dozens of variables and hundreds of models. But the next big advancement in multivariable control may be a shift toward the use of small-matrix, model-less multivariable control practice...

Have you ever heard someone say, “The job is a lot easier if you have the right tools?” Having the right tools is critical to the success of craftsmen, such as carpenters, electricians, plumbers and the like. The same holds true for managing projects. Initiating a project raises many questions (such as: What will we do? How will we do it? Who will do it? How much will it cost? When will we do...

FRI’s membership has been growing steadily since 2006. As a result, I have more bosses every year; at present, 78. I receive input from them in several ways. They attend quarterly meetings. They respond to surveys and votes. They send emails. They call. Primarily, this column describes the projects that are presently of the most interest to the membership. In 2013, 8-ft-dia. two-pass valve trays were...

Corrosion and deposition in boilers, steam turbines and many types of process equipment are among the most expensive causes of outages in utility and industrial steam plants. Deposits and scale buildup on heat-transfer surfaces reduce efficiency, and when allowed to accumulate on steam turbines, such buildup can reduce the capacity. Corrosion-related failures can result in outages ranging from a few days...

Petroleum refineries generate power from a number of sources, including cogeneration plants and steam networks. Generally, steam networks use turbines to improve operational reliability, specifically as drivers for rotating equipment. Due to increasing energy costs, it is essential to maximize the power-generation capabilities of steam networks. This article presents a spreadsheet-based optimization model...

One of the chemical process industries’ (CPI) foremost authorities on process safety, Trevor Kletz, passed away in late October at the age of 91. Amongst Kletz’s many achievements, one that stands out is his extensive contributions to the concept of inherent safety — a technique to reduce plant hazards through design, for example by keeping a lower inventory of hazardous chemicals on hand...

Capital cost calculations I recently read the article “Capital Costs Quickly Calculated” [ Chem. Eng., pp.46­–52, April 2009] and find it extremely informative and useful. I have reservations about the example given about the cost comparison of two spherical storage tanks. The authors state that the costs of spherical storage tanks are proportional to surface area, therefore, to the...
