At combined-cycle power plants, a problem in even the smallest piece of equipment can cause significant downtime and lost production. Valves, in particular, must operate at peak performance to ensure consistent plant operation.
First of Two Parts
This column discusses valves and fittings and evaluates how these devices affect the operation of piping systems. Valves and fittings connect pipelines, direct flow, and isolate equipment and parts of a piping system. Hydraulic energy is used to move fluid through the piping system.
Many industries are interested in reducing fugitive emissions. Several standards and end user efforts work toward this goal:
Standards groups in the U.S. and abroad have been actively advocating for compression packing used in valve stem sealing. Some of the more relevant provisions and changes are outlined in this article.
In the Middle East and North Africa (MENA), the oil and gas market is highly competitive. Petrochemical plants must provide services with as little disruption as possible to maintain production and meet market demands. These facilities handle hazardous materials that require constant monitoring, and the equipment in these challenging environments is typically difficult to access and maintain.
Predictive monitoring of critical rotating and non-rotating equipment is important for successful plant operation. Two end users benefited from this type of real-time monitoring of their critical assets. They were alerted to small abnormalities that could have escalated to expensive interruptions, helping maintenance personnel take a more preventive approach.
Liquefied natural gas (LNG) is natural gas in a liquid form that is clear, colorless, odorless, non-corrosive and non-toxic. It is produced when natural gas is cooled to minus 259 F (-161.66 C) through a process known as liquefaction.
The North South Interconnection System Project (NSISP) is one of South Australian Water Corporation’s (SA Water) biggest infrastructure projects in the Adelaide metropolitan area. SA Water built the $403 million project to connect the north and south drinking water distribution systems and to increase access to a desalination plant.
