Steam-Air Tube Decoking Advantages and Disadvantages

The most important advantage of steam-air decoking is that it takes less time than mechanical decoking and eliminates the need for plug headers, which have leakage problems and a maintenance requirement. A further advantage is that the decoking technique is well developed and reliable; the results are rarely unsatisfactory.

The disadvantage of this method is that it consumes large quantities of medium pressure steam and utility water and produces hot, coke-laden effluent water. This stream may create a hazard to personnel, cause coke accumulation problems in the sewer, and need treatment before disposal. Hearing protection may be needed in the vicinity of the decoking knockout drum.
