What is the installation height for a high-position ammonia absorber?
Thread Content
When producing melamine as a by-product, must the installation height of the high-position ammonia absorber be greater than 35 meters? ? ? Right? ? ?
The high-ammonia absorption unit used in melamine production – the type I designed features an inner tube with slanted holes, and it worked extremely well; it was in use for five years until production was discontinued. I remember that the capacity was 1,000 tons, with three high-mounted ammonia absorbers; their installation height was around 20 meters. After absorbing ammonia, the liquid was cooled before being fed back into the tank. It is recommended that you calculate the resistance of the pipeline equipment first and select an optimal value before determining the installation height of the ammonia absorber.
The height of our company’s high-altitude ammonia absorber is around 25 meters, and it uses negative pressure jetting to absorb ammonia. There is a type of absorber available in China called a falling film absorber, which absorbs ammonia while simultaneously cooling it; I think this type of absorber should be quite effective. I wonder if it is useful?!
