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...

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...

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...

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...

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...

Polymers like polyethylene, polypropylene, polyvinyl chloride and polyester have become ubiquitous in manufacturing. The properties of polymer-based materials that make them so desirable — they are generally cheap to produce and boast high chemical and thermal stability — also make them abundant, disposable and, in many cases, non-degradable. As landfill space decreases, and with some European...

Each year, the U.S. Environmental Protection Agency (EPA; Washington, D.C.; www.epa.gov) honors innovative technologies that make an impact in reducing hazards to human health and the environment. As these are goals that the chemical process industries (CPI) continuously strive for, news of such achievements is of great interest. Over the past 18 years of the Presidential Green Chemistry Challenge program...

When the U.S. Occupational Safety and Health Administration (OSHA) revised the U.S. Hazard Communication Law, U.S. 29 CFR 1910.1200, in May of 2012, it set off an avalanche of change in the environmental, health and safety (EH&S) circles of American industry. Virtually every manufacturing and service industry will be involved in one aspect or another of adapting its existing hazard communication system...

Chemical, pharmaceutical and related industries produce large amounts of wastewater in their production and cleaning processes. The wastewater characteristics are often diverse, and may include minimally biodegradable or toxic substances, or both. To protect the environment, these wastewaters typically must be treated to minimize pollutant concentrations before discharging to the environment, or to...
