Reactive chemicals and intermediates are used extensively in the chemical process industries (CPI). Hazardous chemical reactivity can be defined as “any chemical reaction with the potential to exhibit rates of increase in temperature and/or pressure too high to be absorbed by the environment surrounding the system” [1]. Reactive materials can be classified into two groups: self-reacting...

From plastics and synthetics to fertilizers and fuel, the general public takes for granted so much of what the chemical process industries (CPI) produces, and the risks associated with CPI production facilities are not typically considered. That is, until the next headline-creating industrial catastrophe occurs. The human toll of such disasters plays out across ruined lives, devastated communities and...

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...

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...

"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...
