Ammonia production ... Modern production process . In one preferred use of the loaded sorbents, the container of water is a toilet bowl. 5,160,512 discloses a method for removal of a gas constituent from a gas stream employing a composite sorbent material. U.S. Pat. FIG. In all of the cases, no mixing was employed, and pH readings were taken near the top of the container. Ammonia production process. The ammonia gas may slowly desorb within the pouch until an equilibrium is reached with the small amount of ammonia gas in the pouch, at which point no more ammonia will desorb from the sorbent. The most preferred charging conditions are 2.5 hours at 5 PSIG for a zeolite 13X material. Thermodynamic Data 4. From the work completed, it appears that 13 x 1/16" pellets yield the best results, as seen in the above data. 1 shows a schematic illustrating the apparatus 1 which is used to produce the sorbent material 7 which are exposed to ammonia gas. 12. Less common applications are in aluminum etching, to saponify oils and fats, and in manufacturing. endstream endobj 51 0 obj <> endobj 52 0 obj <> endobj 53 0 obj <> endobj 54 0 obj <> endobj 55 0 obj <>stream 0000003876 00000 n The specialized soluble plastic film remains intact until it contacts a solution of water at a pH of 10.3 or greater. Referring now to the drawings in greater detail, FIG. FIG. 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 When ready for use, the contents of the pouch are dropped into a container of water. 0000001332 00000 n h�b```f``z������� �� �@���q@��A�Z"�t���L�2�c`p4JY6e��T1�Dv��g���^y�h,�y�}մi�W&�h^����"�0Rxqq"{Хc=VӦ��l�6 �U0-�H 2. %PDF-1.3 %���� 0000000989 00000 n �ꇆ��n���Q�t�}MA�0�al������S�x ��k�&�^���>�0|>_�'��,�G!

After loading by exposure to ammonia gas, the loaded sorbent is then placed into an air and water tight container for storage. 08/636,412, filed Apr. The method as claimed in claim 4 wherein said sanitary napkin is disposed of, after it has been significantly degraded by said ammoniated water, by flushing it in a toilet. There are various manufacturing processes to produce aqua ammonia. 2y�.-;!���K�Z� ���^�i�"L��0���-�� @8(��r�;q��7�L��y��&�Q��q�4�j���|�9�� Introduction 2. It is an object of the present invention to provide an improved method of dissolving an ostomy pouch, sanitary napkin or incontinence pad. The pH values were taken at the center of the pot, approximately 0.5" below the surface of the water. 8 grams of sieve is very easy to package in a small foil pouch. Facility Policy: The management and employees of this facility are committed to the prevention of any accidental releases of anhydrous and aqua ammonia through the use of proper equipment, regular 2) The loaded sorbent can be added into a separate pouch (plastic bag), which may be flushable, but not dissolvable by ammonia water. endstream endobj 56 0 obj <>stream Water and at least one of the loaded sorbents would be placed into the disposal pouch and the pouch would be sealed. The precipitate composition is disclosed as being used as an adsorbent composition for acidic malodorous gases such as hydrogen sulfide and alkaline malodorous gases such as ammonia. At the end of this 2 hour period each sample was removed from the NH3 environment and weighed. allowing said person to inhale said ammonia gas. This is a Division of Ser. Manufacturing process of ammonia • Introduction • In large scale commercial ammonia production plants, the feedstock which makes up the reactants are water, methane and air. Aqua ammonia corrodes copper (and copper-containing alloys such as brass), zinc, cadmium and silver. 0000002855 00000 n The above-mentioned sorbents have a much stronger affinity for water than for ammonia. 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. 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.
