Control design for steam vent noise in refineries

Chadha, V., Bhandari, S., Virdi, P., Bechtel Corp.

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.

Optimize steam usage in refinery flares

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).

Unintended fugitive emissions from pressurized plant components have long been a key concern for operators as well as regulators.

Design a pressure safety valve at the centrifugal pump discharge

Kadam, N., Daelim Industries Co. Ltd.

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.
