Determining the proper preliminary size for centrifugal pumps during the initial stages of any pump-specification exercise requires numerous calculations and assumptions. This article reviews the steps needed to size centrifugal pumps during the early stages of a project, to support initial cost-estimation efforts. Such early pump-sizing efforts are important steps toward final pump selection and detailed...

Pressure-relief valves are widely and effectively used in situations where the pressure in a process vessel rises to above the vessel’s design-pressure rating. Proper relief-valve sizing is critical to plant and process safety to permit fluids sufficient flow area to exit the vessel. Sizing relief valves requires several equations for different flows (liquid flow, vapor flow and two-phase flow), as...

An industrial compressed-air system is expected to supply air of defined quality, required pressure and desired quantity to all the plant air and instrument air consumers. With air being one of the most critical utilities of a chemical plant, a compressed air system should function efficiently and cost effectively. Therefore, designers should consider parameters such as air quality, air consumption and...

When it comes to rotating machinery (pumps, compressors, gas turbines, steam turbines, turbo-expanders, and others) operating in the chemical process industries (CPI), installation, piping, support, pre-commissioning, commissioning and startup play crucial roles. Machinery maintenance and repair can be quite costly, and perhaps because of shortages of skilled manpower, particularly at remote site...
