Maintenance & Reliability

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,

Fired heaters in the process industries: Optimizing operations and minimizing emissions

Finnan, K., Meyer, E., Yokogawa Corp. of America

The process industries, which include chemicals, metals and mining, oil and gas, petrochemicals, pulp and paper, and refining, are very energy intensive

Improving process pumps requires technical and managerial action

Bloch, Heinz P., Hydrocarbon Processing Staff

For many years, manufacturers have emphasized low price over high reliability.

Extracting business value from digitalization in oil and gas

Bradley, D., Petasense

Most oil and gas companies are investing in digitalization; however, they often fail to move beyond proof of value (PoV) or pilot projects.

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.

Increase uptime by reducing systematic failure risk

Siew, H., Endress+Hauser

Pondering the history of industrial incidents, it would be incorrect to assume that most failures occur randomly.

Reboiler pinch: An approach to optimize flare system design during FEED

Amin, H., Saudi Aramco; Dhote, P., Kanade, S., Siemens

A process plant’s pressure relief and flare systems are critical safety elements.

Achieve process safety, asset integrity and reliability with an integrated HAZOP study

Chakravorty, S. L., Independent Consultant

Abnormal situations in refining and petrochemical plant operations can interfere with plant reliability and efficient operations, especially for highly complex processes.

Safety: Addressing corrosion at petrochemical plants starts with carbon

Dalton, B., Thermo Fisher Scientific

Maintaining the structural integrity of a pipeline is a significant investment of time and resources for organizations in the oil and gas industry.
