Webused to pull a vacuum with motive steam pressure as low as 5 pounds per square inch gauge (psig), higher pressures of 15 to 50 psig are more practical. Example For a required compression ratio of 2:1 (15.3 + 14.7 psia)/(0.3 + 14.7 psia), 1.1 lb of high-pressure motive steam per lb of low-pressure suction steam is required. The thermo- WebMaking low-pressure steam through a PRV is inefficient. For steam flows over 50,000 lb/h, it is usually far more cost effective to extract by-product power by passing the steam through a backpressure steam turbine. When the low-pressure steam is produced through a turbine, its cost is calculated as: CL = CH – 1000 x aE x (HSH – H* SL)/3413 ...

Web24 sep. 2024 · The perfect steam balance has no energy losses from steam venting, excessive low-pressure steam venting, flash steam venting, condensate loss, and so on. However, a high percentage of plants do not have a steam balance program, which typically leads to the following results: flash steam being vented; Webprocess at a given pressure (150 psig) and passes through a steam trap to a lower pressure (0 psig @ 212oF), then a percentage of the condensate will flash to steam. The vented condensate receiver allows the flash steam to be vented to the atmosphere and ultimately lost from the system.
