Noise pollution in oil refineries has a direct effect on worker health. Noise is the unwanted or undesirable sound produced by process control equipment, which includes valves.
In this study, methods to optimize the consumption of dispersion steam in flares were examined at a large refinery that burns a considerable quantity of gas. The desired optimization was achieved by monitoring hydrocarbon emissions using an infrared camera (thermography).
Turnarounds in continuous operating process plants, such as refineries and petrochemical processing plants, are complicated and costly events where each day of downtime equals lost revenue.
Pentair is working with major chemical and petrochemical companies around the world to promote and implement standardization programs and processes with the goal of increasing efficiency and reducing total cost of ownership in areas such as procurement, installation, and maintenance of valves and controls equipment, and inventory control processes across multiple plant sites.
The EVOS DCi valve is among a number of digital concept solutions that Linde is developing in order to demonstrate leading edge digital technologies for the packaged gases sector.
Emerson has signed an agreement to purchase the valves & controls business of Pentair for $3.15 B.
This article is the second under the “Codes and Standards” series.
Unintended fugitive emissions from pressurized plant components have long been a key concern for operators as well as regulators.
In most process plants, it is unusual to install a pressure safety valve (PSV) to centrifugal pump and compressor discharge, but some PSVs are needed and are installed to protect the system against miscellaneous scenarios that could create overpressure in the system.
The FM-approved FireChek thermal shutoff valve with resettable memory shape alloy can now be used to automatically shut down a pneumatic control system when a nearby fire occurs, or when the ambient temperature reaches 135°F, 150°F or 165°F.
