Abstract
Methods and apparatuses for controlling exothermic reactions involving a first reactant contained in a liquid and a second reactant in a gas to form a reaction product by atomizing the liquid in an environment of a gas and removing heat of reaction by condensing vapors of the liquid in a reaction chamber. Preferably, the condensation takes place on a simultaneously atomized second liquid of lower temperature than the atomized liquid containing the first reactant. The compositions of the two liquids are preferably similar. This invention provides waste minimization and considerable environmental improvement.

A method of making a reaction product different than carbon monoxide or carbon dioxide in a reaction zone by reacting a first reactant contained in a first liquid with a second reactant contained in a gas, the first reactant and the second reactant characterized by an ability to react with each other in an exothermic manner, the method comprising the steps of:
- atomizing the first liquid to form a plurality of first droplets having an average droplet size in the gas at a first flow rate, at a first atomization temperature, and at a reaction pressure;
- reacting at least partially the first reactant with the second reactant to form the reaction product and release heat;
- evaporating at least part of the first liquid, thereby removing at least a portion of the released heat;
- and
- restricting the portion of removed heat within predetermined limits by causing controlled condensation within the reaction zone.
A method of making a reaction product different than carbon monoxide or carbon dioxide by reacting a first reactant contained in a first liquid with a second reactant contained in a gas, the first reactant and the second reactant characterized by an ability to react with each other in an exothermic manner, the method comprising the steps of:
- dividing the first liquid into a first stream and to a second stream;
- causing the first stream to have a first atomization temperature and the second stream to have a second atomization temperature lower than the first atomization temperature;
- atomizing the first stream to form a plurality of first droplets in the gas at a first flow rate and at the first atomization temperature;
- atomizing the second stream to form a plurality of second droplets in the gas at a second flow rate and at the second atomization temperature;
- reacting at least partially the first reactant in the first droplets with the second reactant to form the reaction product and release heat;
- and
- maintaining first droplet temperature within predetermined limits by
- evaporation of at least part of the first liquid from the first droplets, and
- condensation of at least part of the evaporated first liquid o n the second droplets.
