Methanol ammonia scrubber cooler
Thread Content
After the ammonia coolers in various plants discharge ammonia (containing oil, water, and ammonia) into the ammonia storage tank, how is the ammonia inside that tank recovered?
Liquid ammonia containing impurities such as oil and water is sent to the ammonia vaporization tank, where it is heated by low-pressure steam (the ammonia vaporization tank is of the jacketed type); the liquid ammonia then vaporizes into gaseous ammonia, which returns to the main gaseous ammonia pipeline, thereby enabling recovery!
The common practice is to use collection tanks, heating coils, and drain pipes; the best approach, however, is to employ temperature control valves to maintain a constant liquid level
Here, we press it into the central collection tank for recycling.
We have ammonia waste pipelines that lead to a tank; there are also pipelines connecting to the ammonia vapor pipeline and the ammonia storage tank, with gaseous ammonia being sent directly into the vapor pipeline while liquid ammonia is sent to the ammonia storage tank!
The ammonia recovery storage tank is designed below the ammonia cooler, allowing ammonia to flow in naturally. The liquid phase is pumped to the recovery unit, while the gas phase is connected to the inlet of the ammonia compressor
