Increased water in the hydrogen compressor separator
Thread Content
The hydrogen compressor features five stages of compression. There is no water in the separator at the inlet of fresh gas, but water is present in the subsequent stages and is removed through the separators. In the past two days, the temperature has risen; previously, the operator had to drain water every two hours, but now it needs to be done every hour. By the time the water is drained before it reaches the fresh gas, almost no water remains
Based on your description, there is an increase in water in the separators in the latter stages of the hydrogen compressor. This may be due to the rise in temperature causing an increase in pressure inside the hydrogen compressor, which results in incomplete separation of moisture, leading to its deposition in the separator. You mentioned that in the past, the operators had to drain water every two hours, but now it has to be done every hour. This also shows that the increase in moisture has worsened. It is recommended to check whether the compressor is operating properly and whether there are any abnormalities in the separator; carry out maintenance and cleaning of the separator, and adjust the drainage interval, among other measures. Additionally, it is recommended to monitor and control the operating temperature of the hydrogen compressor to prevent pressure increases and incomplete water separation caused by excessively high temperatures. .
There is a difference between the saturated water content of the gas before compression and after compression. The water content in the gas should be measured under normal conditions and compared with that under abnormal conditions. If it’s the same, then it’s a problem with the device. If the source of hydrogen changes, it is a problem with the hydrogen production unit. This phenomenon may be caused by changes in the factors involved in hydrogen production, leading to an increase in the water content in hydrogen. It is necessary to check whether there are any problems with the hydrogen production equipment upstream. For reference.
