Patent GB-2006728-A (GB)
Title: Metals separation from dragstream material of refining process
IPC: C10G21/14
Filed: 1978-07-13
Abstract: The refining of crude oil charge stocks rich in metal contaminants leads to the formation of a dragstream concentrated in such metals and it is desirable to calcine the dragstream material to recover the metal values. However, treatment of dragstream material in an oven causes the material to creep and become a flowing plastic mass and this renders calcination difficult. The present invention proposes the treatment of the dragstream with naphtha at elevated temperature and pressure followed by separation of the resulting relatively low metals content organic liquid material from the residual solid material which is readily calcinable.

Title: Reclamation process
IPC: B29B17/02
Filed: 1978-10-04
Abstract: Recovery of industrial or sorted collector's waste containing at least one malleable, thin sectioned material such as copper, tin, lead, silver, aluminum or malleable alloys and/or plastic materials which are malleable at selected temperatures, such as thermoplastics and thermoplastic rubbers, is accomplished in a dry process by first cutting and/or grinding to a suitable size and thereafter impacting the materials to form the malleable materials into spheroids having apparent densities in proportion to their malleabilities.
