Economy Pressure and vacuum solutions

Vacuum pressure is measured relative to ambient atmospheric pressure. It is referred to as pounds per square inch (vacuum) or PSIV. The electrical output of a vacuum pressure transducer is 0 VDC at 0 PSIV (14.7 PSIA) and full scale output (typically 5 VDC) at full scale vacuum, 14.7 (0 PSIA).

  • Economic Efficiency in Vacuum Generation

    Economic Efficiency in Vacuum eneration5 In industry, “vacuum” is understood as pressure that is less than the prevailing atmospheric pressure. When describing different levels of vacuum, the paradoxical peculiarity of the technical jargon can irritate laypeople: the lower the pressure, the higher the vacuum.

Mostof his working career was spent in the U.S., although he later returnedto Europe where he is buried in the famous PereLachaise cemetery in Paris.

    One solution to the problem of air in the system is to increase the steam pressure and thus "force" the system, however, this results in higher temperature steam, delayed warm up, uneven steam distribution and wasted fuel. The removal of air with an efficient mechanical vacuum pump solves this air problem in a very economical manner.

  • 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...
