Caring for Cooling Water Systems
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…
Tank Coatings: Covering the Basics of Selection and Specification
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…
Facts at Your Fingertips: Sedimentation Centrifuging
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…
Controlling SO2 Without Corroding the Bottom Line
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…
Feature Report: Computerized Maintenance Management Systems For Effective Plant Performance
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…
Engineering Practice: Corrosion Resistance Using Rock and Glue
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…
Engineering Practice: Seal-Fluid-Circulation Devices: Understanding the Differences
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…
Operations & Maintenance: Technology and Scheduling: The Perfect Chemistry
By utilizing efficient scheduling software, companies in the CPI can improve enterprise agility and compliance In the fast-paced and ever-changing world of chemical processing, companies are constantly trying to keep up with the latest technology, while at the same time…
Avoiding Seal Failure
Seals are assemblies of elements that prevent the passage of a solid, liquid, gas or vapor from one system to another. When a seal allows leakage of material, failure has occurred. This guide provides an overview of common seal types…
Feature Report: Green Engineering and the Design of Chemical Processes and Products
Chemical products and processes make modern life possible. The systems that provide housing, transportation, health care, and food for billions of people rely on chemical products, but as demand for these essential materials grows, the environmental impacts of the products…
