Reduce the problems associated with handling hazardous liquids by following these guidelines Pumps are one of the most ubiquitous items of equipment found in chemical processing plants. Often, they are used to transfer hazardous liquids, such as flammable, combustible, toxic…
Careful control of water and steam chemistry at CPI facilities can pay off handsomely in reliable operation Sometimes lost in the hustle and bustle of production issues at chemical-process-industries (CPI) facilities is that high-purity water, and steam produced thereby, is…
The failure of a device or of a group of components can lead to overpressurization and subsequent adverse events, such as fire, explosion, spill or release. The most common causes of overpressurization are listed below. Understanding the circumstances surrounding overpressurization…
Hydrocarbon leaks can disrupt recirculated cooling-water systems. Here’s an outline of effects and remedies Water is often the fluid of choice for cooling systems in the chemical process industries (CPI). Recirculated cooling-water systems are used to control the temperature of…
The interior surfaces of your storage tanks are constantly at risk. If you walk past a tank often without giving thought to what is happening on the inside, it is because you trust the interior coating to protect not only…
Centrifugation is the method of choice in the chemical process industries (CPI) for separating solids from liquids. It relies on the G-forces generated by high-speed rotation to recover solids or liquids from slurries, as well as clarify liquids or classify…
Among the many types of pollution-abatement systems that are in use today, wet fluegas desulfurization (FGD) systems — also known as wet scrubbers — are notoriously capital- and maintenance-intensive. These systems are widely used by electric power plants and chemical…
Corralling gigabytes of predictive maintenance data isn’t easy, but it’s essential for streamlining your process Plant maintenance is one of the disciplines in a chemical process environment that uses gigabytes of technical and operational data on a daily basis. Of…
Low-cost, corrosion-resistant castings are being produced using epoxy and mineral aggregates Stainless steel, painted and plated cast-iron and steel structures are being replaced at a fraction of the cost with high-precision polymer castings (PPCs). PPCs can usually be cast to…
Knowing the options in fluid-circulation designs helps in the selection process Over the past few decades, hundreds of seal geometries and a fair number of seal categories have evolved. Recently, the distinction between single- and dual-mechanical seals has been brought…
