Acetylene Cylinder Processing System

Disposal of acetylene cylinders presents a unique challenge in that these cylinders not only hold acetylene gas, but also contain a porous mass and liquid acetone. The mass often contains asbestos and the acetone can leak out if the cylinder is landfilled. The safest and most responsible way to manage acetylene cylinders when they have reached the end of their useful life, is to remove all of the gas and acetone before the cylinder is landfilled.

Standard practice for handling waste acetylene cylinders is to vent the non-toxic acetylene gas to the atmosphere and allow the cylinder to remain open to the atmosphere for 30 days.

IES, along with sister company Precision Technik, has developed a mobile, automated processing system by which the extended venting time is eliminated. This process actively vents any residual gas and recovers liquid acetone from each cylinder. This process enables cylinders to be disposed of through landfilling without the risk of introducing organic solvents into the landfill or groundwater.

Extraction of both residual acetylene gas and resident solvent (acetone or DMF) is accomplished by heating the target cylinders over an extended period of time at a temperature above the solvent boiling point and inducing a vacuum at the cylinder valve connection port. Chemical components are transferred in their vapor phase through system piping to a condenser and liquid solvent collection tanks.

Once the automated heating cycle has been completed, a plug is placed into each cylinder outlet. The cylinder is now considered to be empty of any liquid solvent or residual acetylene gas. The mass inside the cylinder is safely sealed inside and the cylinder carcass is ready for disposal as solid waste in a landfill. (Typically, this mass contains varying amounts of asbestos and therefore the landfill should be approved to handle this kind of waste.)

To ensure safety, an automated control system monitors and operates the process using an array of sensors and actuated valves. These engineering controls allow system operators to monitor conditions at all times.
