If oil is present in the wastewater feed entering the stripping tower, it will cause foaming to occur as per the process specifications, or an increase in the hydrogen content in the acidic gases; this in turn leads to a decline in the quality of the purified water and ammonia gas, severely affecting the stripping efficiency of the tower. Oil in acidic water can lead to the accumulation of large amounts of oil within the tower, disrupting the vapor-liquid equilibrium there and causing operational fluctuations that affect product quality

The biggest problem with acidic water carrying oil is that it leads to the presence of hydrocarbons in the acidic gas; these hydrocarbons end up in the sulfur production furnace, resulting in insufficient air supply. This causes significant fluctuations in the ratio of hydrogen sulfide to sulfur dioxide, which in turn leads to excessive levels of sulfur dioxide in the flue gases. The solution is to increase the oil-removal efficiency of the acidic water tank, or replace it with a more efficient oil remover during maintenance ； At the same time, coordinate well with the upstream units to minimize the carryover of oil in acidic water to sulfur.

I would like to ask for some good methods for removing oil.
