The system can include a first shell having two or more discrete catalyst beds disposed therein, a second shell disposed about the first shell, a first heat exchanger disposed external to the first shell and in fluid communication therewith, a second heat exchanger disposed external to the second shell and in fluid communication therewith, and a flow path disposed within the first shell. A first portion can be reacted in the presence of the catalyst to provide an ammonia effluent. The heat of reaction from the ammonia effluent can be exchanged within the first heat exchanger and the second heat exchanger. The heated second portion of the feed gas can be introduced to the first shell and can be reacted in the presence of the catalyst. | 05-28-2009 |
| 20090304558 | APPARATUS, SYSTEM, AND METHOD FOR GENERATING A GAS FROM SOLID REACTANT POUCHES - An apparatus, system, and method are disclosed for generating a gas. One or more liquid permeable pouches each define a cavity that contains a solid anhydrous reactant, such as a chemical hydride. A reaction chamber made of a heat, chemical and/or pressure resistant material receives the one or more pouches from a pouch feeder that transfers the one or more pouches into the reaction chamber successively at a feed rate. One or more liquid sources inject a liquid reactant into the reaction chamber so that the liquid reactant contacts a portion of the one or more pouches. The one or more liquid sources inject the liquid reactant at an injection rate that corresponds to the feed rate. A gas outlet releases a gas, such as hydrogen, oxygen, ammonia, borazine, nitrogen, or a hydrocarbon, that is produced by a reaction between the solid reactant and the liquid reactant. | 12-10-2009 |

| 20140363344 | AMMONIA CAPTURE RECOVERY SYSTEM - An ammonia capture recovery system is disclosed. The ammonia capture recovery system may include pretreatment with conventional solid removal devices and a single or a series of hydrophobic membrane concentrators receiving a heated ammonium containing influent either heated to a sufficient temperature to convert ammonia to ammonium or containing sufficient alkali to convert ammonia to ammonium in the influent. The heated ammonium containing liquid is pumped through the hydrophobic membrane concentrator and the hydrophobic membrane concentrator receives an acid. The acid then reacts with the extracted gaseous ammonia and ultimately forms a saturated ammonium salt product that is discharged from the hydrophobic membrane concentrator, the hydrophobic membrane concentrator includes a feed line, a plurality of hydrophobic membrane modules, a diluted acid source and a concentrated acid source and tanks to receive the saturated ammonium salt product and the low ammonia effluent. | 12-11-2014 |
