Abstract: A vacuum deposition facility for continuously depositing, on a running substrate, coatings formed from metal or metal alloy, the facility including—a vacuum chamber and a device for running the substrate through the vacuum chamber along a given path, wherein the vacuum chamber further includes:



a central casing including a substrate entry and a substrate exit located on two opposite sides of the central casing and a vapor jet coater, the inner walls of the central casing being suited to be heated at a temperature above the condensation temperature of the metal or metal alloy vapors,
a vapor trap in the form of an external casing located at the substrate exit of the central casing, the inner walls of the vapor trap being suited to be maintained at a temperature below the condensation temperature of the metal or metal alloy vapors.

Abstract: A method for manufacturing direct reduced iron wherein iron ore is reduced in a direct reduction furnace by a reducing gas, the reducing gas exiting the furnace through the top as a top reduction gas. The top reduction gas is captured and at least partly subjected to a CO2 recovery step during which it is divided into two streams, a CO2-rich stream and a CO2-poor stream. The CO2-rich stream is subjected to an alkanol production step to produce an alkanol product.
