Compressors

Advances in compressor anti-surge valve design enhance reliability and performance

Haines, B., Nelson, M. P., Flowserve Corp.

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,

Unconventional improvement of propylene recovery yield at the PP splitter

Capra, M., Aggreko

Thermocompression-equipped propane-propylene (PP) splitters are used to upgrade large quantities of refinery-grade propylene (RGP) to polymer-grade propylene (PGP).

Engineering Case Histories: Case 110: A checklist for vibration analysis

Sofronas, A., Consulting Engineer

Periodically, I receive questions from engineers around the world on why a piece of critical machinery is vibrating excessively.

High-pressure gas compressor dry gas seal system enhancement case study

The Khurais producing department (KhPD) consists of four oil trains: each oil train is responsible for receiving, stabilizing and purifying the crude oil from the wells by removing sand, water, gas and hydrogen sulfide (H2S) contents to make the oil ready for use and shipment to refineries.

Business Trends: Autonomous operations in process manufacturing—Part 1

Agnihotri, R., IBM Corp.

Progress in the driverless car segment has served to illuminate one of the major future goals in industrial and process manufacturing: autonomous operations in process plants—in other words, the autonomous plant. While AO for process plants has received interest from the process automation and control industry, limited serious discussion has taken place in the process operations and IT domains.

Reliability: Reliability engineering on offshore platforms

Bloch, Heinz P., Hydrocarbon Processing Staff

Offshore platforms have had their fair share of successes and failures over the years, and to say that their reliability experiences contain lessons for all of us is an understatement.

Variable capacity control technology facilitates efficient operation for reciprocating compressors

Sanford, J., Siemens

Reciprocating compressors are used extensively in refinery and petrochemical operations to keep feedstocks and products moving through miles of piping.

Design of very-high-flow coefficient centrifugal compressor stages

Jariwala, V., Elliott Group

Centrifugal compressors are widely used in the oil and gas and petrochemical industries, with more than 15,000 operating in the U.S. alone.

Optimization: Plan before main air blower disaster strikes

Weeks before a planned overhaul of its coker unit, a synthetic crude plant’s main air blower for the furnace failed, throwing the engineers’ plans into disarray.
