Reliability: Exploring better compressor sour seal oil traps

Bloch, H. P., Professional engineer

An interesting case involving sour seal oil traps in an offshore application recently came to our attention.

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

Nichols, Lee, Hydrocarbon Processing Staff

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.
