16,000 cfh (Electrically heated or gas fired). Configuration We can build (and have built) high pressure systems with retorts designed to operate up to 30 psi but discourage high pressure systems unless there is no alternative. This means heat goes into the chamber and the process, not the room. You don’t have to remove one to get to the other. dissociators are typically air cooled. “Our cracker technology is underpinned by a low-cost metal membrane technology which is uninhibited by ammonia, and infinitely selective to hydrogen, allowing the stringent ISO14687-2 standard to be achieved,” according to Michael Dolan, a scientist at the Commonwealth Scientific and Industrial Research Organization (CSIRO) in Australia. 4. We also assume the equipment is to be installed on a reasonably smooth, level and non-combustible floor. atmosphere generators we do supply nickel (or iron) catalyst in other configurations such as 3/4″ and 1″ cube, and 3/4″ and 1″ spherical. The shell temperature of a. dissociator is significantly cooler than others. We normally expect residual ammonia levels, for our standard low pressure systems, to be below 50 ppm at capacity, it is not uncommon for Thermal Dynamix™ standard low pressure dissociators to operate with residual ammonia at levels well below 20 ppm. The Nitrex ammonia dissociator as a part of a nitriding installation The resulting gas consists of 25% nitrogen and 75%. A vertical retort maintains its heating element clearance even as it ages. The electrically heated dissociators have no pumps, motors, fans, blowers or other moving parts to wear, make noise or maintain. You don’t have to guess about what’s going on inside. dissociator or ammonia cracker, as it used to be called, is designed to separate . Supplemental water cooling of the process gas is available if the need exists for lower gas output temperature. dissociators are simple. Groups in Australia, Japan, Denmark, the U.K., and the U.S. all made progress with technologies that can be used to convert ammonia to hydrogen at fueling stations. We also assume the equipment is to be installed on a reasonably smooth, level and non-combustible floor. First, write the chemical equation for the dissociation of the acid. When ammonia vapor is dissociated the resulting gas mixture is extremely dry, with a dew point of typically -40 °F to -60 °F. While the actual residual ammonia levels may vary with specific installation circumstances, it is not uncommon for a standard Thermal Dynamix™ ammonia dissociators to produce residual ammonia levels below 20 ppm. And finally, Thermal Dynamix™ dissociators are simple. ammonia dissociator is a remarkably simple, durable and efficient machine which achieves virtually 100% dissociation of a clean, dry supply of anhydrous ammonia with very few moving parts and only the energy necessary to complete the dissociation process. Even though a. dissociator is so durable and simple that it doesn’t need much service there will come a time when maintenance is necessary. standard low pressure dissociators to operate with residual ammonia at levels well below 20 ppm. An added benefit, in most cases, is the elimination of an electrical transformer (although a very large dissociator may still require a transformer). All Rights Reserved. Shown here is our Model AD10E; a 1,000 cfh electrically heated unit. The ADG Series Ammonia Dissociators range from 150 scfh to 5,000 scfh at a standard outlet line pressure of 10 psig. They are more compact, easier to install and replace, less expensive and generally longer lived than metallic element systems. ammonia dissociators are available, either electrically heated or gas fired, in the following nominal sizes (CFH): ammonia dissociator retort. The absence of such a clear, open channel significantly reduces residual ammonia amounts. In the last 12 months … There is no opportunity for the catalyst to settle to the bottom of a horizontal tube leaving a clear channel, free of catalyst, at the top. A group of researchers from Japan has now discovered a new method of producing hydrogen from ammonia at room temperature, which may represent a step forward for the hydrogen … This means that hydrogen for fuel cell vehicles can be handled as ammonia from the point of production to the point of dispensing. Ammonia Energy Anniversary Issue: a “top five” development in technology advancement. Thermal Dynamix™ dissociators are generally designed for indoor installation but can be configured for outside installation and operation. However, the advent of effective and efficient ammonia-hydrogen conversion devices that can bridge the gap between an ammonia-based logistics network and the class of hydrogen-powered cars, puts ammonia right back into the picture. A vertical retort configuration allows either a single heating element (or the whole set) to be removed and replaced without disturbing the retort or, conversely, allows the retort to be removed and replaced without disturbing the heating elements. Click to learn more. Pressure gages on the retort(s) and heat exchanger(s) give advance warning of the need to schedule maintenance. We can build (and have built) high pressure systems with retorts designed to operate up to 30 psi but discourage high pressure systems unless there is no alternative.

NH3 + ΔH ⇌ 2 1 N 2 + 3 H 2 (1) In a thermochemical storage system, the whole system operates at the high pressures that are needed for effective ammonia synthesis. A vertical retort configuration is very convenient. A vertical retort won’t “sag” under load. Even though a Thermal Dynamix™ dissociator is so durable and simple that it doesn’t need much service there will come a time when maintenance is necessary. We use 1/2″ spherical, nickel catalyst in the Thermal Dynamix™ ammonia dissociator retort. The engineering design of the Thermal Dynamix™ dissociator assumes a clean, dry supply of anhydrous ammonia vapor (less than 2ppm water; 2ppm oil and no sulfur) at a pressure not exceeding 35 psig and a temperature of at least 50 °F. Ammonia is comprised of two elements: nitrogen and hydrogen. Because a vertical retort is uniformly supported around its entire circumference it isn’t subject to this sag. 4. You don’t have to remove one to get to the other. 6,000 cfh (Electrically heated only) An ammonia . A Thermal Dynamix™ ammonia dissociator is a remarkably simple, durable and efficient machine which achieves virtually 100% dissociation of a clean, dry supply of anhydrous ammonia with very few moving parts and only the energy necessary to complete the dissociation process. special brazing alloys or brazing fluxes. dissociator uses a vertical retort configuration with silicon carbide heating elements. We also have designs for dissociators of up to 32,000 cfh capacity either electrically heated or natural gas fired. The working temperature in the retort chamber of a dissociator is generally in the 1750 °F to 1900 °F range.
