Regarding the vaporization of liquid ammonia
Thread Content
Liquid ammonia is supplied to the manufacturer (storage tank – heater – pressure regulator), but there is still liquid at the inlet of the equipment; the length of the pipeline is around 100 meters. The heating temperature is 40°C; I wonder why there is still liquid present?
Is there frost on the pipe wall? Is the heat not enough?
There’s no pleasure in it, and there’s also a heater
It could also be that the heat exchanger area of the heater is insufficient, and it is unable to vaporize all the liquid ammonia at such a flow rate.
Check if there are dead zones in the piping or if the flow rate is insufficient.
The heating power can be increased a bit.
Add heat mixing to the pipeline, use a thicker insulation layer, and eliminate bag-shaped areas that may form during pipeline installation
Could there be water in that dead corner of the pipeline, resulting in ammonia?
