Compressors: N2 Expands the Applicability of Dry Gas Seals
Ongoing advances in the design and use of dry gas seals (DGSs; [ 1]) — as an alternative to traditional oil-lubricated wet seals [ 2] — have helped to improve the reliability and efficiency of compressors throughout the chemical process industries (CPI). One of the major design considerations in mechanical seals is how to protect seal faces from wear, as one face rotates close to a static face...

Integrating Gas Turbines Into CPI Facilities
To realize the best possible thermal efficiency, gas turbines should be integrated into chemical process industries (CPI) plants, but doing so can be difficult and requires special consideration. Specifically, in some CPI units, while the turbine’s shaft is driving an equipment component (such as a compressor), the hot exhaust gas from the gas turbine can be connected to furnace burners or...

Design and Specification of A Compressed Air System
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...

CPI Machinery: Commissioning, Startup and Piping
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...

Anti-surge Valves for Dynamic Compressors
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...

Reciprocating Compressors Startup and Capacity Control Methods
There are two main reasons why compressor capacity regulation is used. The most prevalent reason is to adjust the suction flow to match the process demand. The second reason is to save energy. As a rule, capacity control is determined by the compressor discharge pressure. Compressor capacity-control methods are utilized to maintain a required delivery under variable process conditions [1]. In this article...

Lubricating Rotating Machinery
      Lubricants in rotating machines reduce friction and wear, dissipate heat, protect surfaces, keep out foreign contaminants and remove wear particles. Commonly used liquid lubricants fall into two main categories: mineral (petroleum-based) oils and synthetic oils. Mineral oils are produced by refining crude petroleum. They usually contain trace amounts of some unwanted substances. By...
