Pressurizer inlet filter
Thread Content
There is a filter at the inlet of the booster pump in the large air separation unit. The system has been in operation for 2 months yet has not reached full capacity, and the filter shows no signs of resistance. Now some people are suggesting that it be removed; let’s discuss when would be a suitable time to do so
There is a downtime opportunity to check the cleanliness of the filter surface, after which it can be removed.
It is recommended not to remove it; instead, a filter with a finer mesh can be replaced during maintenance, and then it can be removed after one to two years. It was found a year later that there were weld spurs falling off our booster; fortunately, there was a filter in place
It is best not to remove it; keeping it in place helps filter out dust and other particles from the system ahead, preventing these particles from entering the suction valve and causing blockages.
It’s best not to remove it. During maintenance, it can be checked; if there aren’t many impurities, the maintenance interval for the filter can be extended.
Why is it being demolished? Once impurities do enter the system, isn’t it he who has to bear the consequences? It’s normal to have no pressure difference for a month or two; that simply indicates that the process gas is relatively clean, and that’s all.
Agreed; I personally think it’s unnecessary and inappropriate. The compressor must not allow any impurities to enter its interior. Having a filter at least provides some protection.
Today, filters for air separation compressors are all self-cleaning. I’m not aware of the model of the compressor or the type of filter used by the poster; please provide more details so that it’s easier for everyone to analyze and make judgments.
The inlet filter of the booster is clean air that has been purified using molecular sieves
It’s correct to check it every two months when it first starts running. Only then can those in charge of personnel and equipment feel at ease.
In my opinion, it can only be removed during equipment maintenance
