  • Evaluate pressure drop in vacuum systems - Plant Services

    Pressure DropOperating Demand Created by Pressure DropLeaksReduce The Pressure LossResultsWhat is pressure drop in a vacuum system? The idea of pressure drop in vacuum systems is similar in concept to pressure drop in plant compressed air systems. Pressure drop is the difference in operating pressure from the supply point to the use point. In compressed air systems, pressure drop is measured in psid, which means pounds per square inch differential. Pressure drop can be used as a measure of pressure drop in vacuum systems as well, but it is much more common to use inches of mercury as unit of measure. Table 1 illustrates some of the common pressure units used in vacuum and how the scales compare with one another. Note that the top of the table represents atmospheric pressure and the bottom of the table represents perfect vacuum. Also, note that there are two scales that use inches of mercury. Finding the pressure drop in a vacuum system is a simple procedure. First, measure the vacuum at the inlet to the vacuum pump using a reasonably accurate vacuum gauge. Then, using th...

  • Condenser Backpressure High? Check Vacuum System Sizing

    Vacuum System StandardsAir-Venting DevicesFactory Tests Versus Hei RequirementsComparing CalculationsHybrid ArrangementsClosing ThoughtsThe Heat Exchange Institute’s (HEI’s) Standards for Steam Surface Condensersprovides clear directions on capacity requirements for venting equipment when operating in either holding or hogging modes. The capacity in the holding mode is more critical, as it has a direct effect on megawatt generation. The HEI recommends that the capacity of venting equipment in the holding mode “be no less than the values shown in [HEI’s] Table 9 at the design suction pressure to ensure adequate removal capacity under commercial operating conditions.” The HEI defines the design suction pressure for electric generation service as “1.0 inch HgA or the condenser design pressure, whichever is lower.” In addition, the HEI states that the saturation temperature of the gas vapor mixture must be considered as the steam temperature corresponding to the design pressure of the venting equipment less the greater of 7.5F or 0.25 (Tsat –Tcw,inlet). Tsat is the saturation temperature of the liquid in the condenser a...

  • Protect Tanks from Overpressure and Vacuum | AIChE

    Tank Overpressure and Vacuum ScenariosTank Pressure- and Vacuum-Relief SystemsDispersion Consequence ModelingFinal ThoughtsAPI Standard 2000 defines the venting requirements for atmospheric and low-pressure storage tanks for both overpressure and vacuum. The standard covers causes of overpressure and vacuum, including additional scenarios to be considered for refrigerated tanks (Table 2) (2). Note that the causes of vacuum are often the inverse of analogous causes of overpressure. Overpressure scenarios fall into five general categories: 1. liquid inflow caused by normal liquid flow to a tank or by unexpected diversion of liquid to a tank (e.g., liquid heat-transfer fluid ingress from a leak), which can displace the tank vapor space (i.e.,outbreathing) or overfill the tank 2. vapor inflowcaused by the malfunction of a control valve or of a regulator on a tank blanketing system to the open position, breakthrough of pressurized motive gas used for liquid transfer, or mechanical failure of an internal steam heating coil or steam jacket 3. change in heat transfer caused by high ambient temperatures or incre...
