Online help for the production process of mass production of ammonia water using liquid ammonia

The ammonia water used in our factory when starting up is vaporized by liquid ammonia and absorbed by condensate. At this time, cooling water must be introduced to take away the cold and heat.

I understand this principle, but my writing skills are too weak and I can’t write well. Plus I don’t understand the professional terminology, so I’d better ask experienced friends to help me. Haha.

What device requires a large amount of ammonia? The possible process is: After the flow of liquid ammonia in the liquid ammonia tank is controlled by the valve, and at the same time, the ammonia water in the circulation tank is pressurized by the pump, the two are mixed in the ejector, cooled by the water cooler and then returned to the circulation tank. The ammonia water reaches a certain concentration and is available for use. If you want to utilize the cooling capacity of liquid ammonia, the process is as follows: The liquid ammonia in the liquid ammonia tank enters the ammonia cooler after the flow is controlled by the valve, and is heated and vaporized by the medium. At the same time, the ammonia water in the circulation tank is pressurized by the pump, mixed with gas ammonia in the liquid-gas ejector, and returned to the circulation tank after being cooled by the water cooler. The ammonia water reaches a certain concentration and is available for use. Ammonia pipelines need to be equipped with check valves.

Thank you for this post above. I have read it and don’t feel very satisfied with it.

Can you describe the conditions in more detail, such as scale, quality requirements, and production conditions, so that we can help you better.

Preparation of ammonia water: first evaporate into gas ammonia through the vaporizer, and then enter the ejector to absorb ammonia and extract ammonia water. Because ammonia dissolves and releases a large amount of heat, it needs to be cooled to normal temperature by water. Note: The ejector must use soft water or desalted water. If primary water is used, scaling may easily occur and cause blockage.

The carbonization process of synthetic ammonia manufacturers is very classic. After the liquid ammonia is vaporized, it is sent to a high-level ammonia absorber, which is absorbed by carbonized mother liquor. The mother liquor after absorbing ammonia is stored after being cooled by cold discharge or water cooling. If the concentration is low, it can be recycled and concentrated.

You seem to be joking! There are methods for recovering ammonia in ammonia water. But when it comes to using liquid ammonia to produce ammonia water, you have to consider the cost. Is it worth it? This is very simple, use an absorption tower, a circulation pump to adjust the concentration, a cooler to transfer heat, and you have to choose soft water according to your uses and indicators.

Generally, synthetic ammonia plants and urea plants have a large amount of ammonia, which is cheap. It is recommended to buy ammonia and concentrate it yourself. It is more cost-effective to use liquid ammonia, which is expensive. This may not be the answer you want. Generally, making ammonia is to pass liquid ammonia into desalted water or steam condensate or dilute ammonia. There are no technical problems. It is just to pay attention to issues such as volatilization, leakage, and heating.
