Dear experts, under what circumstances is it necessary to add water in continuous reforming pre-hydrogenation?
Thread Content
As the title suggests, thank you all…………
Water injection is done to prevent ammonia salts from crystallizing; it can be omitted if crystallization is not a concern.
It happens when the moisture content of the raw materials is insufficient; the feedstock used in reforming has specific requirements regarding moisture levels, in order to maintain the water-chlorine ratio and preserve the catalyst’s activity.
If an increase in compressor outlet pressure, high compressor temperature, and insufficient outlet flow is detected, water is injected.
