Hydrogen Pipelines | Department of Energy

Gaseous hydrogen can be transported through pipelines much the way Fire Fighting is today. roximately 1,600 miles of hydrogen pipelines are currently operating in the United States. Owned by merchant hydrogen producers, these pipelines are loed where large hydrogen users, such as petroleum refineries and chemical plants, are concentrated such as the Gulf Coast region.

7 Types of Industrial Storage Tanks Explained - GSC Tanks

Gas cylinders are most commonly used for gas storage, with large nuers being produced at “cylinder fill” facilities. However, all of the industrial gases are not supplied in gaseous phase. Some gases are vapors, liquifiion for which can be done under pressure alone at aient temperature, so these gases can be supplied in the form of a liquid too in a suitable container.

Food Packaging Permeability Behaviour: A Report

The gases normally used in the modified atmosphere packaging are nitrogen, carbon dioxide, and oxygen (N 2, O 2, CO 2), whose properties are reported in Table 3 [1, 14, 23].Other gases like Ar, CO, and N 2 O are also under study in the food packaging field [24, 25] but until now few studies were made on the polymer film gas permeability for food packaging appliion.
