Already, in the first two months of this year, the unpredictable and winding road of the so-called Boiler MACT, has taken yet another set of hair-pinned curves. Now industry groups are pushing even harder for an act of Congress that would put on the brakes and allow more time for the regulations to be reshaped. At stake, says Robert Bessette, president of the Council of Industrial Boiler Owners (CIBO...

For the first half of my career, I worked in a group that developed, designed and sold distillation trays. Late during the 1970s, half of that group’s business disappeared — almost overnight — when structured packing replaced trays in very large ethylbenzene-styrene vacuum columns. Even the best of trays could not compete with the low pressure drops of structured packings. In 1985, Norton...

The Nikuradse-Prandtl-von Karman (NPK) equation is the most widely used expression to determine friction factors for fluid flow in smooth pipes [1–3]. It implicitly relates the friction factor (expressed here as f; sometimes called λ) to the Reynolds number, Re. It is shown in Equation (1).   ( 1)     Because the friction factor appears on both sides of the equation, an...

To optimize process control and overall plant performance, magnetic flowmeters (mag meters) are the most widely used devices in many industrial flow-measurement applications. Mag meters are used to measure the flow of water and other conductive liquids by applying a magnetic field to the flowing liquid. Following Faraday’s law of electromagnetic induction, conductive liquid flowing through the...

Head loss due to friction for fluids traveling through pipes, tubes and ducts is a critical parameter for solving turbulent-flow problems in the chemical process industries. The Colebrook equation is used to assess hydraulic resistance for turbulent flow in both smooth- and rough-walled pipes. The equation contains a dimensionless fluid-flow friction coefficient that must be calculated for the properties...

Distillation is one of the most extensively used operations in the chemical process industries (CPI). It is a highly energy-intensive unit operation, and continuously rising energy costs make it imperative to look for ways to reduce energy requirements. Some energy-saving configurations can increase capital investment costs, so the benefits need to be weighed carefully. Various techniques, such as heat...

Rotating machines, such as pumps, compressors, gas turbines, steam turbines and electric motors, play crucial roles in most chemical process industries (CPI) facilities. Increasingly, advanced condition monitoring is being used to improve the operation and maintenance of these workhorse components. The use of well-designed condition-monitoring systems, predictive-maintenance strategies and failure...

A new catalyst design, in which gallium atoms are integrated into the zeolite catalyst structure, can increase yields of aromatic compounds from biomass by 40% in a catalytic fast-pyrolysis process. The higher yields of benzene, toluene and xylenes (BTX), as well as ethylene and propylene, achieved with the gallium-containing zeolite...
