Corrosion is a large and complex issue that is critical to the chemical process industries (CPI) as well as other industry sectors. Corrosion not only affects personal property like cars and homes but also affects commercial assets such as storage tanks, buildings, bridges, process equipment, and all types of piping. While corrosion is seen every day in our personal and professional lives, we rarely pause...

The ability to model a process to see if it meets project requirements and is economically viable enhances the conceptual design. Modeling gives engineers a means to identify the most promising processes, in terms of capital investment and return, and this can be particularly important when the project is environmentally oriented (a so-called green project). Did you ever consider producing a new product...

In designing and sizing relief-device and effluent-handling systems, one commonly overlooked aspect of the performance is examining the potential for low temperatures that can cause the components of the system to reach temperatures below their respective, minimum-design metal temperatures (MDMT), which may result in brittle fracture with subsequent loss of containment. This article points out limitations...

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...
