An inert blanket system includes a reformer that produces hydrogen gas and carbon dioxide. The hydrogen gas is separated from the carbon dioxide. The carbon dioxide is ported to a vapor region of a tank to reduce the flammability of the gases in the vapor region of the tank. Excess carbon dioxide is ported to an overflow system designed to store the excess carbon dioxide for future use or to sequester the carbon dioxide.

Embodiments of the invention are directed to methods, processes, and systems for safely and reliably purifying hydrogen from a gas mixture containing hydrogen and oxygen.

In a method for separating a synthesis gas containing carbon monoxide and hydrogen, a synthesis gas flow from a synthesis gas source is compressed in a compressor and separated into at least three gaseous products. If there is insufficient synthesis gas, at least three separation products are recycled in the compressor in order to separate said products.

Embodiments of the invention are directed to methods, processes, and systems for safely and reliably purifying hydrogen from a gas mixture containing hydrogen and oxygen.

In accordance with the present invention, disclosed herein is a method comprising the steps for producing lower molecular weight hydrocarbons. Also disclosed herein, is a system utilized to produce low molecular weight hydrocarbons.

A neon recovering/purifying system including: a recovery vessel that is arranged on an exhaust gas route and stores exhaust gas, the exhaust gas route being branched and extending from a discharge line; a compressor that increases a pressure of the exhaust gas sent out from the recovery vessel, to a third pressure; an exhaust gas flow rate regulating unit that regulates a flow rate of the exhaust gas whose pressure has been increased by the compressor; a first impurity removing unit that removes a first impurity from the exhaust gas; a second impurity removing unit that removes a second impurity from the exhaust gas from which the first impurity has been removed; a pressure increasing vessel that stores purified gas that has been processed by the first impurity removing unit and the second impurity removing unit; a pressure reducing valve that reduces a pressure of the purified gas sent out from the pressure increasing vessel, to the first pressure; and a purified gas flow rate regulating unit that regulates a flow rate of the purified gas supplied to a supply line of a manufacturing system.

A dip-conduit purification apparatus (102) comprises a purification line comprising a plurality of serially coupled purification conduits (124, 126, 128), each of the plurality of purification conduits (124, 126, 128) having an inlet at a first distal end thereof in fluid communication with an outlet at a second distal end thereof.

It is an object to provide a metal-air battery capable of, in particular, properly discharging produced gas externally, and performing rapid water supply. A metal-air battery according to the present invention is characterized by including a unit body including a plurality of metal-air battery cells; a water supply space provided on a top surface of the unit body and is common to the metal-air battery cells; and a wiring opening which communicably connects with the water supply space and from which wires connected to electrodes of the metal-air battery cells are drawn out. A tubular portion having the wiring opening projects from the top surface of the unit body.

An apparatus/system for generating a high-purity nitrogen gas using a fuel cell includes; a fuel cell that operates by taking in air or a gas containing nitrogen and oxygen, and a fuel gas; a dehumidification mechanism that reduces moisture or water vapor content in an exhaust gas that is extracted from the fuel cell and has a lower oxygen concentration than air; and a filtering mechanism which includes a filter using fibers having different degrees of permeation for nitrogen and oxygen and converts the exhaust gas having a reduced moisture or water vapor content into a gas having an increased nitrogen concentration. The filter recovery ratio is higher when an oxygen concentration of a gas to be filtered is lower. The dehumidification mechanism is a pump unit including a water seal pump to provide an adiabatic expansion chamber in which the exhaust gas extracted from the fuel cell expands adiabatically.

Provided is an apparatus/system for generating a nitrogen-enriched gas reliably and stably using a fuel cell. The nitrogen gas generation apparatus/system comprises: a fuel cell configured to operate by taking in air or a gas containing nitrogen and oxygen, and a fuel gas; and a catalyst combustion mechanism configured to cause an exhaust gas that is extracted from the fuel cell and has a lower oxygen concentration than air to react with the fuel gas on a combustion catalyst, and convert the exhaust gas having a lower oxygen concentration than air into a nitrogen-enriched gas having an increased nitrogen concentration.
