What are the symptoms of a leak in a methanol water cooler?
1 The pressure of the circulating water may increase. 2 The temperature at the outlet of the circulating water may rise. 3 The methanol content in the circulating water may exceed the specified limit
I. Internal leakage: 1. High pressure of the circulating water and substandard water quality; 2. Poor heat exchange, resulting in high temperatures after water cooling. II. External leakage: 1. Excessive levels of toxic gases in the atmosphere; 2. Leakage of liquids (methanol)
Measure the COD at the outlet of the circulating water
It can be seen once the backflow valve for the outlet waterway is opened. Circulating water can be detected. The pressure also changes
We determined the slight leak by analyzing the combustible gas concentration (ppm) at the circulating water outlet； If the leakage is significant, it will be evident both in terms of pressure and temperature.
It will result in a high return temperature of the circulating water, and the pH value will decrease as part of the regular water quality tests. When the leakage is severe, the circulating water flow rate will fluctuate, affecting flow measurement.
In such a synthesis system, methanol will leak into the water, resulting in a high methanol concentration in it, which can be determined through COD testing. In the case of a distillation system, water will leak into methanol, resulting in high moisture content in the product and substandard quality.
Symptoms of a water cooler leak: 1. The pressure at the outlet of the water cooler decreases, while the pressure of the return water in the circulation system increases. 2. After water cooling, the temperature rises and the alcohol level drops. 3. The current of the circulation pump decreases.
In the distillation section, there will be a sudden increase in the moisture content of methanol, an increase in the temperature of the cooling water, and leaks may occur. If the medium flows through the shell side, a methanol odor can be detected, and liquid traces can be found on the floor beneath the cooler
