A galvanic cell or voltaic cell is an electrochemical cell in which an electric current is generated from spontaneous redox reactions.
Galvanic corrosion (also called bimetallic corrosion or dissimilar metal corrosion) is an electrochemical process in which one metal corrodes preferentially when it is in electrical contact with another, in the presence of an electrolyte.

Typical operation cycle of most refrigerated type liquefied gas carriers includes drying, inerting, cooling down, preparation work prior to loading, loading, laden voyage, unloading, ballast voyage, stripping, warming up and gas freeing.
The design standards defined by the International Gas Carrier Code (IGC Code).
Gases can be liquefied by using one of the following methods: 1. Pressurization under normal temperature. 2. Refrigeration and pressurization. 3. Refrigeration under atmospheric temperature.
Gas carriers are tankers intended to carry different liquefied gases used for energy purposes (petroleum gases, natural gases), in the chemical industry or used as a raw material for making agricultural fertiliser (ammonia).
A gas centrifuge is a device that performs isotope separation of gases.
Bottle of the capacity up to 150 liters, charged with gases in special filling stations.
