    Vacuum is a sub-atmospheric pressure. It is measured pressure depression below the atmospheric. The condensation of steam in closed vessel produces a partial vacuum by reason of the great reduction in the volume of the low pressure steam or vapour. The back pressure on the steam turbine can be lowered from 1.013 to 0.1bar abs.

    Low vacuum, also called rough vacuum or coarse vacuum, is vacuum that can be achieved or measured with rudimentary equipment such as a vacuum cleaner and a liquid column manometer. Medium vacuum is vacuum that can be achieved with a single pump, but the pressure is too low to measure with a liquid or mechanical manometer.

  • 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...
