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...

Throughout the chemical process industries (CPI), various chemicals must be injected into process streams to serve a variety of purposes. Chemical-injection systems can be arbitrarily defined as those systems that are used to inject chemicals at a flowrate that is less than 1 to 5% of the main process stream. Table 1 shows a non-inclusive list of chemicals that are typically added into process streams via...

Inorganic acids play a major role in the chemical process industries (CPI). They are used as raw materials, catalysts or finishing and pH control agents in the manufacture of a wide range of chemical products, from fertilizers to detergents, and even foods. Given their widespread use, a major issue in the CPI is the proper and safe handling of the acids, the adequate materials selection for the pieces of...
