When condensate at a higher pressure is discharged at a lower pressure, a part of it is flashed. While many plants recover condensate without flashing it, the separation of condensate and flash steam prior to heat recovery is much more efficient and beneficial.Condensate carries 12% of total energy in the steam generated and utilised. Without a proper recovery mechanism, this energy is bound to be wasted. In order to keep energy requirements to a minimum, it is important that condensate is handled efficiently and energy from the condensate is recovered and utilized for heating up the feedwater.When condensate at a higher pressure is discharged at a lower pressure, a part of it is flashed. While many plants recover condensate without flashing it, the separation of condensate and flash steam prior to heat recovery is much more efficient and beneficial.

Installing a Forbes Marshall Flash Vessel is the most reliable and efficient way of separating condensate and flash steam before heat recovery. Flash steam contains 40 to 50% of the total energy in condensate and can be reused in low pressure applications. The Flash Vessel is a simple vessel in which when high pressure condensate is released, the flash steam is separated out and recovered from the top. The flash steam separated in the flash vessel can be further utilized for low-pressure steam using processes.When it comes to pumping the condensate collected, centrifugal pumps prove to be highly limiting and costly. The Forbes Marshall Pressure Powered Pump Packaged Unit is designed to pump condensate without electricity, using just 3 kg of steam per ton of condensate. It can pump condensate at higher temperatures of 100 Deg C and more.
