Restaging/rerating of centrifugal compressors: Fundamentals, practices and challenges
The primary requirement for rerating or revamping an existing centrifugal compressor is to match the new operating requirements, such as increased or decreased flow, increased or decreased head, or a combination of both. Rerating or revamping is necessary where the existing compressor or compressor train is incapable of meeting the new operating requirement efficiently.
Editorial Comment: Maintenance and reliability—A cornerstone of safe and efficient plant operation
Refineries and petrochemical plants are comprised of a series of crucial processes to produce transportation fuels, products and chemicals demanded by the global market. These processes consist of capital-intensive units that must be maintained to provide reliable performance. Failure to adequately maintain these assets can have a detrimental effect to not only operations and profit, but also to worker safety.

Modular reed valve technology for reciprocating compressors
Hydrocarbon processing plants use reciprocating compressors for process gases in a certain flow and differential pressure range, and double-acting cylinder-piston arrangements are almost always involved.
Advances in compressor anti-surge valve design enhance reliability and performance
Centrifugal and axial compressors are some of the most critical components used within a process plant to handle gases.
Selecting the right rotary control valve
The primary function of a control valve is to regulate flow. Accurate, consistent and reliable performance of this task affects many important process unit or plant metrics,
