The feed-water to be distilled is taken from: the fresh water cooling system the sea cooling water inlet of the condenser the sea cooling water outlet of the condenser The evaporation temperature 40 - 50 °C corresponds to a vacuum of: 60 – 70 % 40 – 50 % 90 – 95 % The ejector pump supplies: Coolant in the form of sea water to the condenser, feed-water for the evaporator and water for the combined brine/air ejector Water for combined brine/air ejector only Feed-water for the evaporator only The vapour generated in the evaporator passes through: The condenser only The demister and condenser The demister only The fresh water produced is delivered to a tank by a: Fresh water ejector Built-in fresh water pump Separately installed fresh water pump Drops of sea water removed by demister: Fall due to gravity into the brine sump Fall due to gravity into the evaporation section Are removed by the fresh water pump The combined brine/air ejector is supplied by: The fresh water pump The ejector pump The compressed air installation The combined brine/air ejector creates a vacuum in the system in order to: Increase the evaporation temperature of the feed-water Decrease the evaporation temperature of the feed-water Decrease the temperature of the feed-water Having reached the boiling temperature, the feed-water undergoes: Total evaporation Partial evaporation Partial condensation In order to obtain the specified flow of hot water it is necessary: To adjust the by-pass valve until the desired jacked water temperature is reached To close the hot water inlet valve To close the hot water outlet valve The air valve installed on the upper part of the separation vessel: Should be open during vacuum creation procedure Should be open after stopping the plant Should remain closed all the time The hot water inlet and outlet valves should be open: When there is a minimum of 90% vacuum Before starting the ejector pump When there is a minimum of 30% vacuum After stopping the plant: All valves must be closed All valves must be closed, except the air valve All valves must be closed except the overboard valve for combined air/brine ejector Too low hot water flow, due to incorrectly adjusted by by-pass valve will cause: High boiling temperature Low boiling temperature and a drop in fresh water production Increase of salinity Too high hot water flow, adjusted by the by-pass, will cause: An increase of salinity An increase of vacuum To low boiling temperature ... specified flow of hot water it is necessary: To adjust the by-pass valve until the desired jacked water temperature is reached To close the hot water inlet valve To close the hot water outlet valve... hot water flow, due to incorrectly adjusted by by-pass valve will cause: High boiling temperature Low boiling temperature and a drop in fresh water production Increase of salinity Too high hot water. .. creation procedure Should be open after stopping the plant Should remain closed all the time The hot water inlet and outlet valves should be open: When there is a minimum of 90% vacuum Before starting
