As process engineers, we design equipment, piping, and other plant components to operate within the conditions that achieve the best operational efficiency and yield on-spec products. However, no one can guarantee that the plant shall always operate within the specified operating envelope. This is because any plant is still subject to lots of disturbances. Disruptions […]
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. […]
