Zardynezhad, S., TurboTech Consulting Corp.

Centrifugal compressors are designed with different suction nozzle orientations and impeller layouts in casing.

Industry Perspectives

Nichols, Lee, Hydrocarbon Processing Staff

With the increasing prominence of hydrogen technologies circulating into the global market, Gulf Energy Information—publisher of Hydrocarbon Processing and Gas Processing & LNG—has launched our latest publication: H2Tech.

How to support condition monitoring with wireless instrumentation networks

Cureton, A., Emerson

When WirelessHART first hit the market in 2008, most of the native devices using it were process measurement instruments.

Modular reed valve technology for reciprocating compressors

Bloch, Heinz P., Hydrocarbon Processing Staff

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

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.
