Low pressure (4.5 kg/cm2) steam is generated by flashing high pressure (42 kg/cm2) condensate in a flash tank. This LP steam is used in the plant which reduces LP steam import from CPP plant.
Due to under design of high pressure condensate flash tank we are not able to completely line up HP condensate (42 kg/cm2g) in the vessel. If we completely line up HP condensate to HP condensate tank, its PSV pops up.
Remaining condensate is flashed in LP condensate flash tank which recovers low pressure condensate and excess vent steam goes to atmosphere.
How to check adequecy of HP condensate flash tank? Its vent line?
