According to the said method, gaseous ammonia is provided by heating a solid storage medium, said storage medium being introduced into a container (1).
Also, since both feedstocks are liquid or solid, there is no need for expensive accompanying equipment as would be needed with gaseous ammonia.
In order to recover the amine from the previously produced by-product amine hydrochloride, gaseous ammonia is introduced into the reaction mixture.
The gaseous ammonia source comprises a tank of solid ammonium, preferably contained within a cartridge of strontium chloride.
A gaseous ammonia source coupled to the mixing chamber is included.
Syngas is cleaned and purified, then used to produce methanol (15), ammonia, or methanol and ammonia.
Liquid ammonia separated from the low pressure mixed vapor-liquid stream can be withdrawn as a low pressure liquid ammonia product (100).
Ammonia injection occurs at a location a plurality of inches downstream of the exhaust valves to avoid burning of the ammonia by flames.
Additionally it enables the efficient release of adsorbed ammonia by regeneration as well as the ammonia recovery as a pure gas for reuse.
The apparatus includes a device for injecting ammonia into a conduit that extends between cylinder exhaust valves and a catalytic converter, to mix the ammonia with the exhaust gases.
When more than 4 % by volume of ammonia is present, the pumping through pipelines is also aided by the refrigerant effect of the ammonia, which reduces the temperature of the gas being transported.
In such a manner, both ammonia and syngas compression can be consolidated in a single syngas compressor (54) and the use of an ammonia refrigeration compressor can be eliminated.
The invention relates to a process for the removal of ammonia from gasification gas by selective oxidation in the presence of a solid catalyst.
A method of inhibiting corrosion in ammonia-water absorption machines that includes adding to an ammonia-water solution soluble silicon compounds.
The invention also refers to such a medium which comprises a gaseous main component and a gaseous additive component, wherein the gaseous main component consists of an essentially inert gas and the additive component comprises ammonia.
Following the product stream ammonia condensation step, the vapor component (94) of the mixed vapor-liquid stream is compressed and cooled for condensing ammonia therefrom.
Ammonia gas is used as the nitrogen precursor for the MBE growth process.
It is obtained by dissolution of ammonia in water.
The process enables an effective and selective separation of ammonia gas from gas mixtures.
This is preferably achieved by plasma etching with ammonia gas.
