Why is methanol sprayed before the transformed gas enters the feed gas cooler? Answer: Since the feed gas cooler operates at low temperatures, if the shift gas enters the feed gas cooler directly and is cooled, the saturated water vapor contained in it will condense and form water. The freezing of this water can cause blockages in the equipment and pipelines. Spraying methanol can capture the moisture and lower its freezing point, thereby preventing the water from freezing and causing blockages in the equipment and pipelines.
