Analyzing upset scenarios is one of the main tasks for process engineers when setting up proper equipment protection. This is clearly shown when preparing the P&IDs, calculating relief loads on the pressure safety valve (PSV) or to the flare system, or carrying out HAZOP / SIL assessment on the current design. Here, a process engineer […]


Ensuring the proper protection of a chemical or oil and gas plant from overpressure is one of the major jobs of a process engineer. This is done by analyzing overpressure scenarios and applying different layers of protection. A pressure safety valve (PSV) is on these protection layers. Designed to release excess pressure within a system, […]


Background In the design of a new petrochemical plant, a centrifugal pump (P-101) was added to circulate the feedstock through a series of downstream equipment, including a heat exchanger (HX-101), which was critical to the operation. The pump was selected based on the process requirements, its main specifications were made based on basic hydraulic calculations. […]


Control Valve failure is a very famous issue while operating a process plant, whether this was in refineries, gas plants, petrochemicals, water treatment, or other chemical industries. This is because a control valve is an essential component that exists abundantly in any process plant. Its failure shall have negative consequences on the operability and safety […]


Suppose we have a pump that draws some fluid from a vessel. The pump flow is controlled on the discharge line and there is a minimum flow controller. So we need to determine the pump specifications to perform the required operation. In order to specify a pump correctly, we need to carry out several calculations. […]
