#Pressure_Relieving_Devices_and_Emergency_Relief_System_Design #Part_2 ● Types of Positive Pressure Relieving Devices : #Relief_Valve: A relief valve is an automatic spring-loaded pressure relief device which is actuated by the static pressure upstream of the valve and opens further as the pressure rises above the opening pressure. It is mainly used for liquid service. Rated capacity is normally achieved at 25% gauge pressure. #Safety_valve: This is an automatic pressure relief device operated by the static pressure upstream of the valve and is characterised by a rapid full opening or "pop" action when opened, but does not reseal. It is used for steam or air service. Rated capacity is achieved at 3, 10 or 20% gauge pressure, depending on the applicable code. #Safety_relief_valve: This is an automatic pressure relief device operated by the static pressure upstream of the valve and is characterised by an adjustment to allow reclosing, either a "pop" or "non-pop" action, and a nozzle-type inlet; it reseats as the pressure drops. It is used on steam, gas, vapour and liquid (with adjustments) and is probably the most common type of valve in refineries, petrochemical and chemical plants. Rated capacity is achieved at 3 or 10% gauge pressure, depending on code and/or process conditions. It is suitable for use as either a safety valve or a pressure relief valve. It opens in proportion to the increase in internal pressure. #Pressure_relief_valve: The term "pressure relief valve" applies to pressure relief valves, safety valves or safety relief valves. #Pilot_operated_safety_valves: When properly designed, this type of valve arrangement conforms to the ASME Code. It is a pilot operated pressure relief valve in which the main pressure relief device is combined with and controlled by a self-activating auxiliary pressure relief valve.

A case study on a refinery with a highly delicate process was experiencing tube leaks in an exchanger for which any fluid mixing was unacceptable to the process. Thus, as soon as the chemistry was detected to be off expected norms, the exchanger would be brought down until the leaking tube could be identified and plugged. Immediate turnaround was the key and Torq N’ Seal heat exchanger plugs turned out to be the solution. #BICMagazine #heatexchangers #tubeplugs Torq N’ Seal® Heat Exchanger Tube Plugs

Using 0.7 bar (10 psig) as pressure drop for a control valve as an initial estimation is a common practice, but it might backfire. This practice applies very well in one case: When you are sizing a new pump for a system with a single discharge point. I mean, as a general procedure we calculate the pressure drop on the system, as 50% dynamic losses + 10% static head, or 0.7 bar, whichever is greater. Then we add it to the calculated pump discharge pressure to balance the equation. But If you already have the pump curve, the only variable you can manipulate is the control valve pressure drop. For systems with more than one discharge point: Let's say a heat exchanger with 0.5 bar dP and bypass control valve controlling the outlet temperature. The head loss on the heat exchanger will determine the dP you need to apply to the control valve, since the upstream and downstream pressures will be known. Even when you are determining the pump discharge pressure, please be reasonable. I've once been given a system where the dynamic losses were 0.2 bar but the control valve dP was 1 bar. This would only increase the Opex and Capex on the pump side and no gain in controllability would be made. Actually we calculated it and 0.5 bar dP was more than enough for that application and provided better controllability. Other cases where the pressure upstream and downstream are fixed and only the valve head loss can be manipulated: 1. When you have a distribution system (supply and return header), like cooling water supply/return or steam/condensate. 2. Discharge to the atmosphere or flare system. 3. The upstream pressure is not determined by a pump but by a equipment (like a reactor). Using an electrolyzer as an example, the pressure on the battery limit is usually around 0.5 bar, therefore a 0.7 bar dP is not acceptable. 4. Gravity transfer: If your source is 4 m high, and the destination is at ground level, you have less than 0.4 bar to operate. What are your experiences with control valve sizing and which mistakes you would advise to be avoided? #processengineering #chemicalengineering #petrochemical #processcontrol

A pressure seal globe valve consists of several key components, each with a specific function to ensure the valve operates efficiently under high-pressure conditions. Working Principle: When the handwheel or actuator is turned, it rotates the stem, which moves the disc up or down. In the open position, the disc is lifted away from the seat, allowing fluid to pass through. In the closed position, the disc presses against the seat, preventing fluid flow. The pressure seal bonnet design ensures that the seal between the bonnet and body becomes tighter as the internal pressure increases, enhancing leak prevention. Applications: Pressure seal globe valves are widely used in industries where high pressure and temperature conditions are prevalent, such as: - Power plants (steam systems) - Oil and gas(refineries and pipelines) - Chemical processing (handling corrosive and toxic fluids) - Petrochemical industries Understanding these components and their functions is crucial for the proper selection, operation, and maintenance of pressure seal globe valves in various industrial applications. #psgbv #gbv #Valves #PressureSeal

Maximum pressure in a pipeline ------------------------------- To calculate the maximum pressure that can be reached in a pipeline with a closed outlet, you need to consider several factors and follow specific steps. Here's a structured approach to determining the maximum pressure and sizing a Pressure Safety Valve (PSV): ----------------------------- Kindly find this important comment from Mr. Vijay Sarathy Chartered Chemical Engineer (M.E, CEng, MIChemE, UK) “ In slide 7, If the project is still at the FEED stage with no pump curves data from the vendor, then a margin between 20 to 25% can be added to the rated point, to account for the shut-off head. In case it is a cross country pipeline, then one can expect line packing raising the pressure over and above the Joukowsky's overpressure. For this a transient simulation with TLNET or Pipenet is a better option to estimate the maximum possible rise in pressure to set the design pressure of the pipeline (and followed by fixing the set pressure of the relief valve). “ #industry #pipeline #PSV #design

Liquid Leaks in Refinery  If a break or serious leak occurs in a line, the pumps should be shut down and all appropriate block valves closed. If possible, suction can be applied to the affected portion of the line unless the resultant entrance of air creates a hazard. In that case, water or inert gas can use for displacement of liquid.  If the leak involves a tank or any large vessel, available lines shouldbe used to pump out the liquid. Trenches, dikes, or diversion walls should be used either to confine the spill or to divert it to sewers or separators.  If the leak is otherwise unstoppable, water may be used to displace the liquid. If a large spill occurs, portable pumps may be required to supplement permanent equipment in recovering the hydrocarbon. If flammable vapors are present, caution must be used in positioning the pumps because the pump drivers may be sources of ignition and personnel exposure may be a concern. Traffic should be controlled and vehicles should be excluded from the affected area. Proper bonding and grounding should be used.  Water spray or steam applied at the emission point of a small leak may aid in dispersing vapors and preventing ignition. It is a good solution for pipe leaks if repair clamps can be used. Also foam may be applied to cover hydrocarbon spills ground, in order to reduce vaporization #oil #refinery #spill #leak #hydrocarbon #crude #gasoline #safety #process #emergency #LPG #LNG #water #learning #inspection #maintenance #engineering #mechanical #chemical #plant #facilities #terminal #oilplant
