After a serious accident at a chemical plant, petroleum refinery or other freestanding industrial facility, the U.S. Chemical Safety Board (CSB; www.csb.gov) may immediately initiate an investigation, often getting “in the air” while the emergency is still unfolding. The CSB team will consist of skilled accident investigators who are often accompanied by independent experts noted for their...

One of the most energy-intensive utilities for many facilities in the chemical process industries (CPI) is the steam system. Traditionally, steam-use optimization has centered on efficient heat transfer and eliminating waste [ 1]. Further optimization can involve a broader look at how steam supply and consumption interact dynamically throughout a large complex. This type of optimization often results in...

Throughout the chemical process industries (CPI), the need to drain a tank or process vessel arises. In batch-type plants, it is a regular occurrence and is one factor that affects the total cycle time per batch and ultimately the entire production capacity of the plant itself.  Figure 1. In a vertical cylindrical, flat-bottom tank, liquid is flowing into the outlet nozzle (point 1) located at x...

Adsorption and absorption play a big role in reducing air pollution in many applications around the world. Studies show that the largest single use of absorbers this year will be to capture SO2 from power-plant flue gas. Adsorbers will be used by many chemical process industries (CPI) to capture volatile organic compounds (VOCs) and odors. A small, but fast growing industrial segment uses ozone and...

Failures of piping due to vibration-induced fatigue are a serious problem in the chemical process industries (CPI) and a matter of concern for the safety and reliability of plant operations. Due to the complexity of flow-induced vibrations in pipes, no closed-form design solutions — those that can be expressed in terms of well-known functions — are available. In this article, we present a...

Reducing freshwater consumption and wastewater discharge at large petroleum-refining and chemical-production facilities can lower costs, while allowing plants to expand production capacities without having to secure additional freshwater resources and without having to enlarge their wastewater treatment plants. The key approaches to saving significant amounts of water are: improved water management...

Quite often, during the design of conveying systems, not enough attention is paid to the design of the conveying pipeline and its components. This disregard often leads to some major conveying system problems such as low conveying rates, conveying line plugging, excessive wear and tear in the conveying line, high conveying system pressure drop, product breakage, fines and streamer generation and product...

I will bet that many readers are familiar with a Teddy Roosevelt quote that includes the following: “It is not the critic who counts…the credit belongs to the man who is actually in the arena...” Ralph Weiland has been in the arena for many years, doing chemical engineering work that has benefitted many people. At the Spring AIChE meeting this month (Houston; April 1–5), the...

Given that readers of this magazine are employed across a wide spectrum of the chemical process industries (CPI), our editors go to great lengths to keep most of our content as broadly applicable as possible. In our technical articles, especially, we try to present information that focuses on unit operations, for instance, as opposed to a CPI niche, such as pharmaceutical processing or cement...

Pneumatic conveying of solid material provides advantages over mechanical conveying systems in many applications, including those that require complex routing, multiple source-destination combinations and product containment. Routing of pneumatic piping offers process operators great layout flexibility, but taking advantage of such design flexibility requires a strong understanding of the complex behavior...

The approaches currently used by process integration specialists to assess the opportunities for the integration of reboilers are frequently erroneous and lead to proposals that have to be rejected at the detailed engineering stages or worse, to commissioned reboilers that do not perform properly. This article examines the integration of both vertical and horizontal thermosiphon reboilers, and covers the...

At one time, the design of distillation columns and other major components for the chemical process industries (CPI) required engineers to make one-at-a-time calculations in order to project what-if scenarios covering the processes, equipment, raw materials and capital necessary for renovation or construction. If an engineer was fortunate, he or she might have had access to central computer facilities that...

Instrumentation best practices that are taught in colleges and published in standards are intended to be broadly applicable, guiding users in every industry and geography. However, for outdoor applications in cold climates, where the temperature can fall below –40°C, the optimum installation may be very different from those recommended via best practices, to ensure reasonable performance...
