【Q&A Question 034】May 24, 2016: What are the reasons for the increase in the water level at the interface of the low-pressure separator? The answer key will be available after responding; scoring is based on answering the key points. Poor separation of high-density oil and water leads to blockages in the downstream sections, while the control of low-density water levels is too strict
1. Water present in the raw materials 2. False liquid level
1. Fault in the drainage liquid control valve； 2. Clogged drainage line ； 3. Excessive water injection ； 4. The operator lacks a sense of responsibility and does not make arrangements.
Generally speaking, there are two aspects: 1. Increased water inflow 2. Poor drainage

The first discharge valve is clogged, and the second material contains a high amount of water
1. Large feed volume； 2. Poor drainage ； 3. Blocked outlet ； 4. False level indication
There are fluctuations in low-pressure levels, with values lower than the operating range; there is blockage in the acidic water outlet path, and the water injection volume increases.
As the hydrogenation depth increases, the water content rises, or the oxygen content in the feed oil increases
