New process for ammonia-containing exhaust gas and liquid ammonia vaporization

Can this set of equipment maintain stable operation during the summer when liquid ammonia vaporization is severe?

Instructions for Use of High-Efficiency Ammonia Absorption Unit I. Introduction: The HAPS series of high-efficiency ammonia absorbers are a new generation of environmentally friendly and energy-saving products developed by our company, incorporating various proprietary and patented technologies. By adopting the \"new process technology for high-efficiency ammonia absorption systems\", liquid ammonia can be efficiently diluted and gaseous ammonia recovered to produce industrial ammonia water, reagent ammonia water, and high-purity ammonia water. Its main advantages are fast dilution speed, simple operation, no pollution, significant energy savings, small size, low space requirement, and easy transportation. The liquid ammonia required for the liquid ammonia dilution system can be supplied from a liquid ammonia storage tank. Liquid ammonia can also be delivered directly using liquid ammonia tankers, and then used through a \"new high-efficiency ammonia absorption process unit\" to produce industrial ammonia water at any concentration below 28%; by using specific equipment parameters or production methods, and with proper cold storage, the concentration can reach 40%. The production process ensures energy savings, safety, and environmental protection. The gaseous ammonia required by the gaseous ammonia recovery system is transported via pipelines to the \"new ammonia absorption process unit for gaseous ammonia recovery\" to produce industrial ammonia water at any concentration of 25% or less. Energy-efficient, ammonia-free, and environmentally friendly in the production process. This device enables fully automatic control; by simply entering the ammonia concentration and pressing a single button, the entire production process can be automated without any human intervention. II. Process flow and production principle: 1. Process flow diagram of the high-efficiency ammonia absorption unit with control points (see schematic diagram) ； The principle of ammonia absorption in the gaseous ammonia recovery system is basically the same as that of absorption using liquid ammonia for dilution; therefore, it will not be reiterated here) ； 2. Production principle: Soft water and liquid ammonia are fed into a high-efficiency ammonia absorber in proportion, where they are directly absorbed to produce industrial ammonia solution of the desired concentration. Use a simple online temperature and density meter to quickly detect the ammonia concentration (which can compare with manual test data) as a basis for adjusting the system process. The small amount of non-condensable gases carried in the liquid ammonia, along with ammonia gas, is discharged from the ammonia water storage tank and enters the exhaust gas purifier, where it is purified with a small amount of soft water before being released ； The large amount of heat released when ammonia dissolves in water is carried away by the circulating cooling water, cooled in a cooling tower, and then reused (the heat exchange efficiency of our company’s equipment is about 4 times that of traditional equipment).

What are the advantages in terms of the cost of the equipment and its operational stability?

Less than 200,000 for 5 tons of liquid ammonia diluted; it’s ready to use and extremely stable. Our own ammonia plant has been in successful operation for 6 years.
