Air Products’ applications engineers can help you evaluate the use of cryogenic liberation in your processes. At our trial facilities around the world, we can cool your multicomponent part by immersing it in liquid nitrogen or in a test chamber of cold nitrogen gas. Our engineers use these tests to establish process parameters for the separation of your part. Then they can use the parameters to develop estimated capital and operating costs for your processes. We can provide the cryogenic system including tanks, piping, and flow controls. We also have a full line of tunnel freezers and conveyors that can be used to cool down parts for the liberation process. Our skilled engineers can work with your current process—from magnetic separation to conveying and grinding—to determine the feasibility and economics of using cryogenics in your process.
Composite parts such as wires, circuit boards or plated pieces present unique challenges to recyclers due to the mix of materials. Cryogenic processing using liquid nitrogen can help recyclers recover more materials for reprocessing.
