The condenser temperature is too high
Thread Content
I’m seeking advice from those with more experience. In the deammonification tower shown in the diagram, the cooling effect of Condenser No. 1 is insufficient, which results in an excessive amount of condensable gas escaping through the non-condensable gas pipelines. This leads to waste of acid used for absorbing both the product and the exhaust gases. What measures can we take? The options being considered for now are: monitoring the flow rate of the circulating water, cleaning heat exchanger No. 1, and adding non-condensable gas pipelines for No. 2
If the condensation effect isn’t good, let’s improve it
……The impact of scaling in the heat exchanger’s circulating water on heat transfer efficiency should be taken into consideration. Should condensers No. 1 and No. 2 be used in series, with non-condensable gases exiting from condenser No. 2 in the end?:)
To address the issue of excessive temperature in Condenser No. 1, you can consider the following measures: 1. Check the circulating water flow rate: Ensure that the water flow in the cooling water circulation system is normal. If the flow rate of the circulating water is insufficient, it can be increased by raising the speed of the water pump or cleaning the water pipes. 2. Clean the 1# tube heat exchanger: If the cooling efficiency of the 1# condenser is poor, it may be due to blockages or deposits inside the heat exchanger. Regular cleaning of the heat exchanger can restore its normal heat exchange performance. 3. Add a non-condensable gas pipeline: A non-condensable gas pipeline can be added at the outlet of Condenser No. 1 to direct the gases that cannot be condensed in the condenser to other treatment equipment for processing, thereby preventing waste of condensable gases. 4. Check the quality of cooling water: Ensure that the quality of the cooling water is good; if necessary, consider using water treatment equipment to treat it, in order to prevent the quality of the water from affecting the cooling efficiency. In addition to the above measures, other options can be considered depending on the specific circumstances, such as optimizing the cooling water circulation system or adjusting the operating parameters of the coolers. It is recommended to conduct a thorough system inspection and analysis before taking any actions, in order to identify the root cause of the problem and address it accordingly. .
