Abstract:
A method for ammonia cracking is disclosed. The method comprises the partial combustion and direct decomposition of ammonia directly on the catalyst in the same location and at the same time, thereby avoiding flame combustion. The control of a catalytic combustion is easier than a flame combustion and improves the control of the reaction by limiting the temperature and its variations.

Abstract:
A reactor tank is provided having an enzyme inlet, a heating jacket positioned around the exterior center of the tank, a gas outlet communicating with a vacuum apparatus and a condensing unit, a first gas inlet for receiving gas from a feed tank and a first liquid outlet for recirculating the liquid back to the feed tank. The tank further includes a sparged unit connected to the first gas inlet for receiving gas from the feed tank and a screen positioned between the sparged unit and the first liquid outlet. The reactor tank is utilized in a reactor system further including a condensing unit, vacuum pump or venturi valve, a first feed tank, a coalescer having at least one circulation pipe and a first circulation pump.
Abstract:
The invention relates to equipment for treating products by means of hydrothermal oxidation, including at least one reactor (1) delimiting a chamber provided with at least: a closable inlet (11) and a closable outlet (12) for the products to be treated; a vent (13); and a closable inlet (14) for pressurized gas, which can be connected to a compressor (2). The equipment comprises two of the abovementioned reactors (1, 10), each reactor (1; 10) further comprising a heat exchanger (15; 105) delimiting at least one circuit (16; 106) for circulating a heat-transport fluid, arranged at the wall delimiting the chamber or inside the reactor (1, 10), and comprising an inlet (17; 107) and an outlet (18; 108) for the fluid, said circulation circuit (16; 106) of the exchanger (15; 105) of each reactor (1; 10) being connected, at the inlet (17; 107) thereof, to the vent (103, 13) of the other reactor (10; 1) via a closable link (6, 5), and being connectable, at the outlet thereof, to a liquid/gas separation means (3).
Abstract:
A full cone liquid spray nozzle is provided. The spray nozzle includes a nozzle body having a discharge orifice at a downstream end and an inlet at an upstream end for connection to a liquid supply. A liquid flow passageway extends through the nozzle body communicating between the inlet and the discharge orifice. A vane is disposed in the liquid flow passageway upstream of the discharge orifice. The vane has a plurality of V-shaped passageways therein. Each V-shaped passageway extends inward at an angle with respect to a longitudinal axis of the vane between an upstream face and downstream face of the vane. A whirl and mixing chamber defined by the liquid flow passageway is arranged between the vane and the discharge orifice.
Abstract:
1. A method for oxidizing a charge that can be oxidized in gaseous phase by a mixture of gases containing at least one oxidizing gas in which the reaction products are collected, characterized in that said mixture of gases and said oxidizable charge are brought into contact in a contact and mixing zone located between at least one first zone passed through by said charge and at least one second zone passed through by the oxidation reaction products thus obtained, said first and second zones defining a multiplicity of multi-directional spaces exhibiting passages having one dimension in at least one direction at most equal to 10 millimetres, this dimension corresponding to the arresting distance of the flame which could result from oxidation of said charge, said contact zone comprising a zone for supplying oxidizing mixture which comprises a plurality of substantially parallel ducts with porous walls and is located a distance from the first zone and the second zone at most equal to the arresting distance.
