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...

One of the most significant limitations on the operation of dynamic compressors (axial and centrifugal compressors) is the low-flow limit known as “surge”. A sudden valve closing, such as for emergency shutdowns or for a suction/discharge valve, presents significant challenges to anti-surge valve sizing and selection. Anti-surge valve requirements depend to a large degree on the compressor...

The prices of low-voltage variable frequency drives (VFDs) have declined substantially since they were introduced, while the cost of power has increased. Normal project economics will now justify these VFDs — which go up to 375 kW (500 hp) or beyond — for pumps over the largest part of the range of application of the pumps. To efficiently evaluate and apply VFDs, process engineers need to know...

Fans and blowers are common in air-handling and movement systems used in the chemical process industries (CPI). Two major uses of fans and blowers are in pneumatic conveying systems and in ventilation and air-pollution-control systems. Powering fans and blowers can contribute significantly to costs, and their efficient operation can be affected by the way plant operators select and run their systems...
