One very important fact to note is that these values of pH were obtained with a pH-meter electrode which was later determined to be improperly calibrated for future experimentation. After loading by exposure to ammonia gas, the loaded sorbent is then placed into an air and water tight container for storage. 42 18 for Aqua Ammonia Production Executive Summary (Revised in accordance with EPA’s requirements for the five year update.)

The present invention produces ammonia water (aqua ammonia) by means of desorbing an ammonia laden sorbent, preferably a zeolite molecular sieve or silica gel into water. Industrial ammonia is sold as either an ammonia liquor or as a pressurized and/or refrigerated anhydrous liquid ammonia transported in tanks cars or cylinders. Alternately, the smelling salt can be exposed to humid air rather than to water. The method as claimed in claim 2 wherein said ostomy pouch is disposed of, after it has been significantly degraded by said ammoniated water, by flushing it in a toilet. No. 8 grams of sieve is very easy to package in a small foil pouch. Household strength aqua ammonia is primarily used with other … Other uses of the sorbent material could include making smelling salt formulations which can be created by adding water to small quantities of the loaded sorbents. Also, a type Y zeolite which can be manufactured by the method discloses in U.S. Pat. These values were obtained in the following manor. 3. The zeolite molecular sieves are quite environmentally acceptable to be flushed into sewage systems, since zeolite materials are currently used as water softening agents in clothes washing detergents. In another case, 7 grams of the loaded silica gel material, type 14-20, was placed into 2.5 liters of water in a glass container, and the pH was observed to rise to 9.5 in approximately 150 seconds. Experiments have shown that the addition of an effervescent substance to the water can be used to facilitate rapid mixture of the ammonia throughout the water container. Diffusion will eventually produce a uniform pH of the ammonia water solution, and this is generally considered adequate. In 1983, on the occasion of the 75th anniversa… In one preferred use of the loaded sorbents, the container of water is a toilet bowl. i need to design unit production aqua ammonia 25% with a capacity 1200 t/day so it is requested from me to design this unit ... An experienced process engineer should be able to come up with the detailed PFD and calcs to determine the actual heat of dilution, the packed bed height, any liquid amm vaporisers and the cooling coils.

There are numerous large-scale ammonia production plants worldwide, producing a total of 144 million tonnes of nitrogen (equivalent to 175 million tonnes of ammonia) in 2016. A method of producing ammonia water (aqua ammonia) by means of desorbing an ammonia laden sorbent, preferably a zeolite molecular sieve or silica gel into water. This application requires that the ammonia contain no additives. It is important, however, to minimize the presence of water in the gas or mixture of gasses during the adsorption process, since water will adsorb preferentially to ammonia in most cases. Subsequent tests indicate that mixing the solution can further improve the pH values at the top of the water container. 0000003876 00000 n Adjust your input water temperature to keep the product … While the pH value of the Ammonia water created by Silica Gel (14-20 Mesh) was one of the lowest values obtained, it was held over for further study due to the fact that it was believed to be much less expensive than the other materials. The adsorbed material can be stored safely until ready for use. 0000000016 00000 n AQUA AMMONIA QUALITY Aqua ammonia is produced by dissolving anhydrous ammonia in water. The method as claimed in claim 1 wherein said water is placed within an ostomy pouch. Below is a summary of the results. In a few plants a portion of the CO2 produced is captured and used to produce urea or methanol. U.S. Pat. Aqua Ammonia is also known as ammonia solution, ammonium hydroxide, ammonia water, ammonical liquor, ammonia liquor, aqueous ammonia, or simply ammonia.. TCC’s Aqua Ammonia is a clear, colorless liquid with a strong pungent ammonia odor. Aqua Ammonia Production Executive Summary (Revised in accordance with EPA’s requirements for the five year update.) Reacts exothermically with acids. The molecular sieve or silica gel adsorbents, with adsorbed gas are referred to as loaded sorbents. The specialized soluble plastic film remains intact until it contacts a solution of water at a pH of 10.3 or greater. 59 0 obj <>stream Ammonia is one of the most highly produced inorganic chemicals. trailer The following procedure was employed for pH vs. time tests. Application: Aqua ammonia (or ammonium hydroxide) is a solution of ammonia in water that has use as a common cleaning agent, in fertilizers, in food production as a levelling agent, acidity regulator, and antimicrobial agent. �F�Eg[�'/�H�H&����Fտ���?e}����O�96|�H�nd7�v�(a�wλ]v,3J(����r���H��W��}7�H�Տ����[�����u��0 �˓i Specific Gravity The specific gravity of aqua ammonia is No. Note: This is a reference cited in AP 42, Compilation of Air Pollutant Emission Factors, Volume I Stationary Point and Area Sources. In one preferred use of the loaded sorbents, the container of water is a toilet bowl. engine exhaust gases, smoke, fumes, flue gases, aerosols, Separation of gases or vapours; Recovering vapours of volatile solvents from gases; Chemical or biological purification of waste gases, e.g. 42 0 obj <> endobj 0000007071 00000 n Ammonia production has become one of the most important industries in the world. 7. In a process known as primary reforming, the natural gas and steam are reacted at approximately 1,000ºC to produce carbon monoxide and hydrogen. The basic ammonia production process, known as the Haber process, uses natural gas, steam and air: First, sulphur is removed from natural gas. FIG.

The preferred sorbent materials are molecular sieves of UOP types 4A, 5A, and 13X, sold by UOP and by Zeochem. 1 is a schematic view of an apparatus used in the manufacture of the present invention. 2,882,244, which is hereby incorporated by reference. A typical modern ammonia-producing plant first converts natural gas (i.e., methane) ... About 80% or more of the ammonia produced is used for fertilizing agricultural crops in the form of aqua ammonia (an aqueous solution of ammonia), ammonium sulfate (NH 4) 2 SO 4, ammonium phosphate (NH 4) 3 PO 4 0000001855 00000 n Second, the weight of the ammonia (NH3) present originally (either as anhydrous ammonia or in the original aqua ammonia) must equal the weight of the ammonia (NH3) in the final solution. Flushable medical devices which can benefit from this technology include liners for bed pans, urinary drainage bags, incontinence pads, sanitary napkin backing sheets, examination gloves, wound dressings, wound drainage bags, surgical drainage tubing, etc., or any device which upon use would become a biohazard disposal problem. A method of using sealed ammonia sorbents which are stored within an air tight container comprising: allowing said ammonia sorbents to contact a fluid until ammonia gas is produced, placing said ammonia sorbents adjacent a person's nose, and. The most preferred effervescent compound is molecular sieve pellets or beads loaded with a refrigerant gas, such as difloroethane or 1, 1, 1, 2 tetrafloroethane. For chemical corrosivity information, see the Materials Compatibility section on page 6. Another method that could be used is to use a fluidized bed reactor. Historical Development 3. xref While it is very easy to make pH 10.3 or higher ammonia water in the lab, it is dangerous to have an ostomate (patient) carry concentrated ammonium hydroxide solution on his/her person. In the prior art various methods of producing ammonia water have been proposed. to provide a sealed container which will hold the ammonia gas sealed inside. There are various manufacturing processes to produce aqua ammonia. In the case of a toilet that has a large "water spot" of about 3 liters, it would take only about 8 grams of loaded Zeolite Type 13X molecular sieve 1/16" pellets to bring about this pH change.
