new Pressure and vacuum plants

Vacuum blowers. Vacuum blowers provide low vacuum levels at a high-volume flow rate, i.e., they have a high suction capacity. Vacuum blowers are also termed 'side channel compressors' and transfer the kinetic energy of a wheel to the air converting the rotary motion into pressure and hence vacuum.

  • Vacuum systems | IPIECA

    The most common system for creating a vacuum is the gas ejector, which uses a high pressure motive gas to entrain a lower pressure stream. Historically, ejectors have been used for a range of vacuum applications from small systems on ancillary plants to very large systems, often with several ejectors in series in refinery vacuum distillation units.

    The final evaporator requires a three stage ejector system to achieve such a low operating pressure. Granulation plants have just an initial concentration stage using a vacuum precondenser followed by a single or two stage ejector system. Granulation typically requires urea melt with water content of no greater than 4 – 5 Wt%.

  • 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...
