Prevent downtime with standby pumps. Manufacturers will greatly benefit from having a run and standby pump within their circuit. Both should be calibrated but only one used at any one time, then interchanged weekly, performing maintenance where needed on the pump that is bypassed. Emergency plans and procedures such as this are critical to reducing downtime. They allow manufacturers to react quickly when issues arise.

Prevent downtime with standby pumps. We've spoken about having standby pumps within your circuit many times before, but with many manufacturers around the world focusing on their production in the lead-up to the festive period, we feel it's fitting to mention again. 🗣️ Manufacturers will greatly benefit from having a run and standby pump within their circuit.

A pressure safety valve (PSV), also known as a pressure relief valve (PRV) or safety relief valve (SRV), is a crucial component in many systems to prevent overpressurization and potential catastrophic failures. Here's a detailed overview of its functions, components, and operation: Function: The primary function of a pressure safety valve is to protect equipment, pipelines, and vessels from excessive pressure buildup by releasing excess pressure to a safe location. This prevents the equipment from failing catastrophically due to overpressure, which could result in explosions or ruptures. Components: Valve Body: The main housing that contains the internal components. Nozzle: Where the pressurized fluid enters the valve. Disc or Pop-Up: The component that moves to open the valve when pressure exceeds the set limit. Spring: Provides the force to keep the valve closed until the set pressure is reached. Adjustment Screw or Lever: Allows for adjusting the set pressure of the valve. Seat: The sealing surface where the disc or pop-up rests when the valve is closed. Bonnet: The cover that protects the internal components. Operation: Normal Operation: During normal operation, the valve remains closed, and the fluid flows through the system without any pressure relief. Overpressure Event: When the pressure exceeds the set limit, the force exerted by the fluid overcomes the spring force, causing the valve to open. Pressure Relief: As the valve opens, excess pressure is relieved, allowing the fluid to escape to a safe location, such as an atmospheric vent or a containment system. Resetting: Once the pressure drops below the set limit, the valve closes, preventing further discharge of fluid. Testing and Maintenance: Periodic testing and maintenance of PSVs are crucial to ensure their proper functioning. This includes testing the valve's set pressure, checking for leaks, and inspecting internal components for wear or damage. Types: There are several types of pressure safety valves, including: Spring-loaded PSVs: Most common, operate using a spring to balance the pressure. Pilot-operated PSVs: Use a pilot valve to control the opening and closing of the main valve. Rupture Discs: A non-reclosing device that bursts at a predetermined pressure to relieve excess pressure. Conventional PSVs: Typically used for gas and vapor applications. Balanced Bellows PSVs: Suitable for applications with backpressure variations. #pressuresafetyvalve #chemicalengineering #processengineering

What is often missing in RCM is a document describing how to inspect equipment while the equipment is operating. In the worst cases, belts, couplings, heat exchangers, control valves, and other common components are, even after the RCM analyses, inspected during shutdowns. Perhaps some inspections have been deleted because equipment was not critical. https://lnkd.in/gfSckxNN #rcm #trap #smartpm

Pressure Reducing Valve (PRV) Automatic Control Valves, Pressure Reducing Valves A Pressure Reducing Valve (PRV) is an Automatic Control Valve designed to reduce a higher unregulated inlet pressure to a constant, reduced downstream (outlet) pressure regardless of variations in demand and/or upstream (inlet) water pressure. Pilot Operated Pressure Reducing Valves The throttled position of the main valve is controlled by an adjustable pilot valve operating in conjunction with an orifice (or needle valve). The pilot valve senses the downstream (outlet) pressure and reacts immediately as the outlet pressure increases or decreases with varying demand. The pilot senses the downstream (outlet) pressure and reacts immediately to add or remove water from the top of the main valve diaphragm assembly, allowing the valve to reposition and throttle as the outlet pressure tends to increase or decrease with varying flow demand. The pilot diaphragm will automatically sense the changes in the flow of the system as it continuously controls the main valve to throttle or to open or close and maintain the desired, preset reduced outlet pressure. The throttling action of the main valve provides the required reduced downstream pressure.

Replacement of low capacity pump with a higher capacity pump and the overall circuit re-evaluation. In case a plant wants to increase its throughput or certain fluid flow, the pump capacity could limit the enhancement opportunity. The existing pump needs to be replaced with a new higher capacity pump to achieve the target flow, however, higher capacity pump means a higher head to be sufficient to deliver the new flow rate. Before installing the new pump, the overall circuit needs to be re-evaluated and HAZOP to be conducted for the targeted loop to study the below points. ▪️The new pump operating/design discharge pressure. ▪️The pump maximum head (shut-off pressure) has to be below the downstream pipelines & equipment design pressure. ▪️If the new pump maximum head is nearing the design pressure of downstream, pressure safety valve (PSV) needs to be installed in the pump discharge to protect the plant’s equipment. ▪️The PSV relief capacity needs to be (at least) similar to the pump rated capacity (blocked discharge case). PSV should be sized as per API 520.
