Devices for making reaction products by controlling pre-coalescing temperature and transient temperature difference in an atomized liquid
First Claim
1. A device for preparing a reaction product from a first liquid containing a first reactant and a gas containing a second reactant comprising:
- a reaction chamber having an upper end, a lower end, a wall, and a reaction zone, in which zone the first liquid is brought in contact with the gas for reacting at a reaction pressure;
an atomizer disposed within the reaction chamber adapted to break the first liquid into a plurality of droplets within the gas at an atomization temperature in a manner that the droplets coalesce on a mass of a second liquid containing reaction product, the droplets having a pre-coalescing temperature before they coalesce, the mass of the second liquid having a second liquid surface, the atomizer being away from said second liquid surface at an atomization distance;
a first temperature monitor for measuring the atomization temperature;
a second temperature monitor for measuring the pre-coalescing temperature;
control means connected to the first and the second temperature monitors for obtaining temperature information and pointing a parameter or determinant selected from a group consisting of pre-coalescing temperature of the droplets, transient temperature difference of the droplets, and a combination thereof, toward respective predetermined ranges, the transient temperature difference of the droplets being the difference between the pre-coalescing temperature and the atomization temperature; and
a separator communicating with the reaction chamber for separating the reaction product from the second liquid.

Abstract
Devices for making reaction products by atomizing a first liquid (in the form of droplets) containing a reactant into a gas containing a second reactant. The reaction is controlled by monitoring the pre-coalescing temperature (temperature of the droplets just before they coalesce into a mass of liquid), or transient temperature difference (difference between the pre-coalescing temperature and the temperature of the droplets just before being atomized), or transient conversion (conversion taking place in the time interval between the formation of the droplets and their coalescence into a mass of liquid) or a combination thereof.
