Cylinders preparation

After arrival of discarded acetylene cylinders to our plant, the cylinders are categorized according to the type of solvent. Transport caps and valves are removed from the cylinders.

Solvent discharge

Distillation of acetone from the cylinder takes place in a water bath. Distillation of DMF from the cylinder takes place in a specially modified gas furnace. Distilled solvents are used for secondary use.


By burn off of the valve thread and cylinder body are all cylinder devaluated to prevent the cylinders from being misused during transport for final recycling.

Smelting in furnaces

Vítkovice Heavy Machinery operates electric arc furnaces for steel manufacture and production of steel products where the devaluated acetylene cylinders serve as basic input raw material.

Asbestos is only dangerous in its fibro-crystalline structure. Its melting at a temperature above 1150 ° C, which is its melting point, switches to a harmless inert mineral.
