Answer: C. a separator is used in lithium bromide plant to remove the unwanted water vapour by condensing
Explanation
A rectifier rather than a condenser separator removes unwanted water vapor in absorption plants. Lithium bromide plants use water as refrigerant and lithium bromide as absorbent. Statement C is incorrect because lithium bromide plants do not use a condenser separator for water. Lithium bromide absorption systems cannot operate below zero degrees Celsius due to ice freezing. Lithium bromide salt is nonvolatile and remains entirely within the generator and absorber. Liquid heat exchangers transfer heat from weak solutions to strong solutions for efficiency.
Building air conditioning chillers frequently use lithium bromide water absorption technology. Absorber vessels require careful vacuum maintenance to prevent crystallization of lithium bromide salt. Engineers design absorption cycles to utilize waste heat from industrial manufacturing processes. Lithium bromide being nonvolatile is a true statement regarding absorption system chemistry. Operating below zero Celsius is impossible because water freezes at zero degrees. Solution concentration increases inside the generator as refrigerant vapor is boiled off.
