Based on the test data of the purified water, identify any operational issues and make appropriate adjustments (the purified water contains 112 ppm of hydrogen sulfide and 175 ppm of ammonia). Answer: (1) The heating at the bottom of the tower is insufficient; increase the amount of steam (or other heat source) accordingly； (2) The side-stream extraction ratio is inappropriate; adjust the side-stream extraction ratio ； (3) Internal leakage in the heat exchangers for raw water and essence water; the leaking heat exchangers are shut down for maintenance ； (4) The pressure at the top of the tower varies significantly, and the amount of acidic gas discharged is low; identify the causes of these pressure fluctuations and control the pressure in the stabilizer as well as the quality of the acidic gas discharged ； (5) A significant increase in the concentration of the feed water reduces the processing capacity, making it difficult to maintain stable operation.
The sulfide content in yours is way too high!

Answer: (1) Insufficient heating at the bottom of the tower; increase the steam supply (or other heat medium) appropriately； (2) The side-stream extraction ratio is inappropriate; adjust the side-stream extraction ratio ； (3) Internal leakage in the heat exchangers for raw water and essence water; the leaking heat exchangers are shut down for maintenance ； (4) The pressure at the top of the tower varies significantly, and the amount of acidic gas discharged is low; identify the causes of these pressure fluctuations and control the pressure in the stabilizer as well as the quality of the acidic gas discharged ； (5) A significant increase in the concentration of the feed water reduces the processing capacity, making it difficult to maintain stable operation.
Based on the test data of the purified water, identify any operational issues and make appropriate adjustments (the purified water contains 112 ppm of hydrogen sulfide and 175 ppm of ammonia); if it is a dual-tower system, increase the temperatures at the bottoms of the hydrogen sulfide stripping tower and the ammonia removal tower. Increase the amount of alkali injected at the bottom of the deamination tower.
By analyzing the data, it can be seen that the purified water does not meet the standards. The adjustment steps are as follows: (1) If the heating at the bottom of the tower is insufficient, increase the amount of steam (or heat carrier) appropriately ； (2) The side-stream extraction ratio is inappropriate; adjust the side-stream extraction ratio ； (3) Internal leakage in the heat exchangers for raw water and purified water; the leaking heat exchangers are shut down for maintenance ； (4) The pressure at the top of the tower varies significantly, and the amount of acidic gas discharged is low; identify the causes of these pressure fluctuations and control the pressure in the stabilizer as well as the quality of the acidic gas discharged ； (5) A significant increase in the concentration of the feed water reduces the processing capacity; stable operation must be maintained
