Solutions to the problem of impurities blocking level instruments during the startup of low-temperature methanol washing process
Thread Content
Dear colleagues, during the startup process of our plant, a small amount of impurities in the system blocked the pressure transducer tubes of the level gauges, resulting in false level readings. Some of these level gauges are equipped with interlocks, which severely affected the safety and progress of the plant’s startup process; it’s really a tricky situation. Do you have any good preventive measures and corresponding solutions for this issue? I would be extremely grateful if you could share your insights. Thank you so much!
Aren’t most of the level gauges in the low-temperature methanol washing unit double-flange type? A small amount of impurities shouldn’t have any impact, right?
1. Confirm what the impurities blocking the pressure tap tube are 2. Here, we have experienced situations where the pressure tap pipes of some flow meters became clogged by coal ash. Over time, we learned which areas are prone to such blockages, so we clean those areas before starting up the equipment.
We are all double-flange level gauges with flange-mounted diaphragms and silicone oil in the pressure transfer tube. Try replacing it with a gauge with a linked level sensor.
Install strainers at the gas phase and liquid phase ends of the level gauge, and use gaskets in between
First, find out what the blockage is, and then choose to install a Y-filter
