Aquatic nuisance species (ANS) in ship's ballast water are killed by permeating to equilibrium a gaseous mixture consisting essentially of, preferably, ≧84% nitrogen, ≧11% carbon dioxide and ≦4% oxygen through ship's ballast water until the ballast water itself becomes (i) hypercapnic to ≧20 ppm carbon dioxide, and, by association, (ii) acidic to pH ≦7, while preferably further, and also, being rendered (iii) hypoxic to ≦1 ppm oxygen. The permeating is preferably realized by bubbling the gaseous mixture preferably obtained from an inert gas generator through the ballast water over the course of 2+ days while the ballast water is continually maintained a pressure less than atmosphere, preferably −2 p.s.i. or less. The (i) hypercapnic, (ii) acidic and (iii) hypoxic conditions—each of which can be independently realized—synergistically cooperate to kill a broad range of ANS in the ballast water without deleterious effect on the environment when, and if, the ballast water in which the balance of dissolved gases has been changed is discharged.

A generator of inert gas from an airflow, in an inerting system for at least one aircraft fuel tank is disclosed. The generator includes a system with an air inlet and means for distributing the airflow to a plurality of air separation modules arranged in parallel on the air system to deplete oxygen in the air and generate a nitrogen-enriched inert gas at the outlet. The generator also includes a programed control unit for the distribution means to selectively supply air to a single, a portion or all of the air separation modules, depending on the flight phase of the aircraft.

The invention discloses a process method and device for producing oil by pyrolysis of high-molecular polymerization waste. The process method comprises the following steps of extruding the high-molecular polymerization waste through an extruder, mixing the extruded high-molecular polymerization waste with a bed material, feeding the mixture into a fixed bed pyrolysis reactor, carrying out pyrolysis reaction, removing fly ash from the generated high-temperature oil gas through a cyclone separator, and carrying out heat exchange with nitrogen, then entering a waste heat boiler to recover heat energy, carrying out gas-liquid separation, feeding liquid into a crude oil tank to be stored, and further condensing gas to obtain crude oil, combusting fuel in the inert gas generator to generate oxygen-deficient hot air which is fed into the fixed bed pyrolysis reactor to be in full contact with the mixture, and providing heat for the pyrolysis reaction, and cooling and screening the waste residue, and recycling the bed material for reutilization. The high-molecular polymerization waste is dechlorinated and deacidified after being extruded, so that the problem of corrosivity of a reaction system caused by chlorine and acid gas generated by pyrolysis is solved, the pyrolysis temperature in the reactor is ensured by adopting a multi-section heat supply mode, and the problems of poor heat conductivity and non-uniform reaction heating of the high-molecular polymerization waste are solved.

The system and method for recycling and using the heat from compressed gas produced by a biogas treatment plant. The system includes a biogas cleaning stage and a plurality of compression and heat exchanger stages that allows the heat generated by compressed gases to be harvested. After the heat is harvested, it is delivered to a jacketed vessel containing media used to remove contaminants from the biogas. The media inside the jacketed vessel requires regeneration or stripping of harmful VOCs and other contaminants picked up from the biogas. The system also includes an inert gas generator that creates hot inert gas that is delivered to the jacketed vessel that heats the media located therein to remove contaminants. Because the jacket vessel and the media are simultaneously heated, the system's heat-up time is reduced The system also includes a heat exchanger that partially recovers the heat from the inert gas.

A gas generator comprises a cylindrical partition wall section (22) provided with gas passage holes (23a, 23b) through which gas generated by the combustion of a gas generation agent passes.
