Design a pressure safety valve at the centrifugal pump discharge
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.
Reliability: Transform ODR-OPPM into a worthwhile initiative
ODR, which stands for operator-driven reliability, has recently morphed into a new arrangement of letters: OPPM.

Compare pitot tube pumps with high-speed centrifugal pumps for low-flow applications
When seeking a pump for a low-flow, high-head application, there is a temptation to choose a high-speed (HS) integral gear-driven centrifugal pump because of its advantages over multi-stage centrifugal and other types of pumps.
Advances in dry gas seal technology for compressors
Compressor owner-operators now have unprecedented and solidly verifiable options.
HP Innovations
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.
Williams selects Elliott compressors for Redwater PDH complex in Canada
Elliott will provide three compression trains for the reactor effluent, heat pump, and propylene refrigeration duties at the new plant. The package also encompasses equipment auxiliaries.
