A gas supply system&#x2014;includes a compressor unit, an accumulator unit, a pre-cooling system and a housing. In the gas supply system, the compressor unit is vertically arranged and the pre-cooling system is arranged above the accumulator unit in the housing. The compressor unit and the accumulator unit are covered by one rectangular parallelepiped housing.

A carbody of a railcar includes: a roof bodyshell; a supporting body provided under the roof bodyshell, the supporting body being attached to the roof bodyshell in a state of being positioned in the vertical direction; a rotating body which is threadedly engaged with the supporting body and rotates relative to the supporting body about an axis extending in a vertical direction to be displaced relative to the supporting body in the vertical direction; and a support target member supported by the roof bodyshell through the supporting body and the rotating body, the support target member being attached to the rotating body in a state of being positioned in the vertical direction, a vertical distance between the roof bodyshell and the support target member being adjustable by displacement of the rotating body relative to the supporting body.

A PSA apparatus for high-purity hydrogen gas production is provided which can recover high purity hydrogen gas at a high recovery rate from a reformed gas (hydrogen-containing gas) produced by a reforming process, for example an autothermal reforming process, and containing, as impurity components, at least CO, CO2, N2 and/or Ar, and can contribute to reducing the equipment size, hence reducing the equipment cost. The PSA apparatus for high-purity hydrogen gas B production by removing CO, CO2 and N2 by adsorption from a hydrogen containing gas A, comprises an adsorption tower; and an adsorbent bedin the adsorption tower, wherein, on the occasion of regeneration of the adsorbent bed, a purge gas C is passed through in the direction opposite to the direction of passage of the hydrogen-containing gas A.

In a production method for oxygen, liquid oxygen is taken out from a rectification column of an air separation unit, and is compressed by a pump so that the pressure thereof exceeds the critical pressure. Then, the oxygen is led into a heat exchanger and is heated therein so that the temperature of the oxygen exceeds the critical temperature.

Production method for oxygen

Disclosed herein is a method of firing a gas turbine with LNG which is designed to store the 'cold' of LNG in an the LNG vaporizer. The method comprises supplying liquefied natural gas through heat exchanger tubes in the LNG vaporizer, thereby gasifying the liquefied natural gas by heat exchange with a heat transfer medium recycled through the LNG vaporizer and an air precooler, and cooling the air in the air precooler by heat exchange with the heat transfer medium cooled by the liquefied natural gas when the turbine load is high, and suspending the recycling of the heat transfer medium through the LNG vaporizer and air precooler, thereby causing the heat transfer medium to freeze on the outside of the heat exchanger tubes (for the storing of freezing latent heat) by the 'cold' of the liquefied natural gas supplied, when the turbine load is low, and using the freezing latent heat (stored by the freezing of the heat transfer medium) as a 'cold' source to cool air through the heat transfer medium, when the turbine load is high.
