Gas-liquid dispensers for liuquid air separation plants

1 For all aluminium closed vessels (including water coolers with aluminium fins), the nitrogen seal should be confirmed before cutting the orifice on site and the hydrogen content at the upper orifice should be measured to see if it is within the normal range. Before cutting, the nitrogen seal nut should be gently unscrewed to release the nitrogen seal pressure and air must be kept circulating at the release site. After the nitrogen has been released, dry air should be used to displace any hydro...

For the technical characteristics of non-standard large air separation units, combined with the actual use of the following aspects of the innovative use of new technologies and methods, design innovation to achieve the purpose of development.The shape design of the gas inlet and outlet pipelines of the adsorption tower focuses mainly on the design of a reasonable local proportion of the pipelines, under the premise of realising the process function. This improved design must combine engineering...
