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…
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…
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…
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…
What we can do to support its goals Green engineering, as explained by chemists and bio-scientists, includes production of energy and materials from "green" feedstocks, such as biomass and microorganisms, with the intent of reducing energy, waste, greenhouse gases (GHGs)…
Demanding application requirements coupled with improved downstream control devices and enhanced instrument diagnostics have led to major changes in process-valve monitoring and control. Factors driving these changes in the chemical process industries (CPI) include the need for lower plant operating…
Although current process simulators contain an extensive library of thermodynamic models and unit operations, they do not contain many new, complicated, or lesser known models. For many companies, particularly those in the petrochemical refining industry, it is very important to…
