  • Plant Engineering | Why absorption chillers fail

     · Since the absorption chiller is very dependent upon its internal vacuum being maintained, loss of vacuum from an air leak will cause system failure. The leak would have to be detected and stopped before a vacuum was restored and the unit placed back on line. In the real world, absorbers are tricky to maintain.

  • Refinery Terminology | refinery4refiners

     · The Bromine Number is useful as a measure of aliphatic unsaturation in gasoline samples. The data showed that the Bromine Number of gasoline is about 2.4 times the olefin content. A gasoline with Bromine Number of 30 would then have an olefin content of about 12.5 percent by volume.

  • Bromine as a disinfectant

    Bromine can be used for the disinfection of cooling tower water. Hypobromous acid is slightly less effective than hypochlorous acid in killing microorganisms. The pH value of the cooling water determines which form of bromine is present. When the pH value is below 8,7, more hypobromous acid (HOBr) is …

  • How do absorption chillers work?

    Michael Faraday came up with the idea of the absorption chiller based on this concept in 1824. The principle behind an absorption process is to separate and recombine to fluids (refrigerant and absorbent) to create a cooling effect. Usually, absorption chillers are either NH 3 -H 2 0 (ammonia-water) cycle or LiBr (Lithium bromide) cycle.

  • Absorption Chiller, How it works

     · How Absorption Chiller Works. First of all a mixture, of around 50% lithium bromide and 40% water, is pumped from the absorber through the heat exchanger and then up into the generator. This line is refereed to as the the weak solution line because the lithium bromide is mixed with water. The generator section is part filled to form a reservoir ...
