Operators and engineers in the chemical process industries (CPI) who are responsible for the daily operations associated with sludge dewatering and drying equipment are undoubtedly aware that wastewater-sludge drying is not an easy task. A large number of the problems that arise during these operations are due to the sticky phase of sludge, which makes the drying of sludge as much an art as a science...

Water and wastewater treatment are extremely important at liquefied natural gas (LNG) facilities and other industries that are blossoming due to the shale-gas boom. Engineering concerns are similar to those of other industrial water-treatment and power-generation systems, but with the added issue of adequate treatment for entrained hydrocarbons. With proper system design and operation, plant personnel can...

Laboratories, such as those used for quality control in a production environment and those in research and development, are an integral part of the chemical process industries (CPI). Everyday demands of business can easily overtake safety when it comes to setting priorities in the laboratory. Deadlines must be met. Samples must be analyzed. Questions must be answered — and quickly. But even for the...

Historically, many large industrial facilities, including power plants, have relied on once-through cooling, in which the entire cooling water volume flows through the plant heat exchangers and then is discharged to the original source. However, the U.S. Environmental Protection Agency (EPA; Washington, D.C.) has, for over a decade, been developing regulations to protect aquatic life from impingement and...

Many industrial gases are transported, stored and used in liquid form, a situation that poses significant health and safety risks. This one-page reference highlights good safety practices for preventing personnel injury when working with cryogenic fluids. High-purity industrial gases, including nitrogen, oxygen, helium, argon and other noble gases, are commonly generated by air-separation units (ASUs)...

Water scarcity is one of the most serious global challenges of our time. Desalination and water reuse are effective and reliable means to provide new water resources. Among the many methods available to treat water, reverse osmosis (RO) has widely demonstrated superior reliability and cost-effectiveness at removing dissolved species, such as salts and trace contaminants. This article reviews the...

Ensuring the security of industrial control systems (ICS) can be a daunting and complex task, requiring expertise and experience in several areas from a variety of contributors. The rapid pace of improvements to both technology and practice adds to the challenge. Finally, the amount and complexity of information, guidance and advice that is available can easily become overwhelming. Rather than focusing on...

Leaks in a chemical process industries (CPI) facility can run the gamut from creating a costly waste to prefacing a catastrophic failure.. They can be an annoyance, by creating pools of liquid on concrete that can become a possible slipping hazard and housekeeping problem, or a leak that can emit toxic vapors, causing various degrees of harm to personnel. In some cases a leak may be a simple housekeeping...

Large petroleum-refining complexes often have dozens of fired heaters, making broad-based competency in this area essential to overall reliability, safety and energy efficiency. Despite industry’s widespread familiarity with fired heaters, they continue to pose significant challenges during initial control-system design and unless properly specified, operated and maintained, fired heaters can hinder...

"As long as fossil fuels and carbon-intensive industries play dominant roles in our economies, carbon capture and storage (CCS) will remain a critical greenhouse gas reduction solution. With coal and other fossil fuels remaining dominant in the fuel mix, there is no climate friendly scenario in the long run without CCS." So begins the 2013 edition of the Technology Roadmap — Carbon Capture...

When flammable or combustible atmospheres are present, uncontrolled discharges of static electricity are potentially dangerous or even catastrophic. A significant portion of industrial explosions and fires are attributable to static electricity each year. In theory, controlling static electricity by grounding potential sources is simple, but in practice, doing so effectively requires thorough knowledge of...

About thirty years ago, my golf foursome learned an important safety lesson and we credited the Dalai Lama. We were all big fans of the movie “Caddyshack.” In that movie, Bill Murray’s character talks about caddying in the Himalayans for the Dalai Lama and states, “So I’m on the first tee with him. I give him the driver. He hauls off and whacks one — big hitter, the Lama...

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...
