A process for creating and controlling the flow of a stream of liquid droplets of a predetermined maximum size in a stream of gas in which the liquid is first passed through a means to produce a fine spray, mist, or fog in the stream of gas and in which the subsequent stream of droplets and gas is treated in a device designed to remove larger droplets and allow the stream of gas containing the small droplets of a predetermined maximum size to pass to the inlet of a gas compressor.

Method and apparatus for controlling liquid droplet size and quantity in a stream of gas

An improvement in the delignification (pulping) of raw cellulose by treatment with oxygen and an alkaline buffer solution at elevated temperature and pressure, which comprises carrying out the process in an unflooded condition, that is, where contact between the raw cellulose and buffer solution is intermittent, both gaseous and liquid phases being present at all times. Optionally, cupric ion may be present as a catalyst.

Oxygen pulping process

A process for wet air oxidation of liquid or solid combustible materials which are insoluble, immiscible and difficult to suspend in water which comprises injecting said materials directly into the wet air oxidation reactor, thereby producing a regular, safe and trouble-free reaction.

Oxidation process

A wet oxidation apparatus comprising a reactor vessel, means for continuously introducing combustible material, water, and oxygen containing gas, into the reactor; the heat of combustion in the reactor being sufficient to evaporate the water supplied to said reactor, means controlling the quantity of water fed to the reactor, thereby maintaining the liquid level in the reactor, and a gas and water vapor outlet for the reactor; gas and water vapor discharging from the reactor being passed through a turbine or similar device to produce mechanical power. The air supplied to the reactor is controlled to be insufficient to oxidize all of the fuel supplied to the reactor, or alternately, the reactor is operated in a way to enrich the gas and water vapor stream discharging from the reactor with organic matter, said enriched stream being subjected to vapor phase oxidation creating a superheated stream improving the efficiency of the power producing cycle.

Regulation of a wet air oxidation unit for production of useful energy

A wet oxidation system comprising a reactor, means supplying liquor and air through preheaters to the reactor, means for cooling the oxidized products from the reactor to substantially less than 200.degree. F, or close to the temperature of the incoming air and liquor, and means for separating the liquid and gas phases at the lower temperature; means for injecting a controlled amount of water into the relatively dry and cool gas stream from the separation means, and means for heating the gas stream with the products from the reactor to substantially completely vaporize the water injected, or completely vaporize and superheat the water injected, and means for delivering the gas stream so generated to a device for recovering mechanical power.

Energy production of wet oxidation systems

A process of treating non-biodegradable industrial wastes by wet oxidation, followed by biological oxidation of the liquid phase by aeration in the presence of biomass and powdered activated carbon, and wet oxidation of the spent carbon and excess biomass to regenerate the activated carbon.
