System and process for the production of combustible substances by depolymerisation of rubber products

A process for the production of combustible substances by depolymerization of rubber products, including a phase of depolymerization with the production of a fluid mixture with two phases, the process comprising the steps of:

• providing an aspiration unit;
• providing a first connecting pipe;
• providing a phases separator, said phases separator comprising a lower base, said aspiration unit being connected to said phases separator via said first connecting pipe, said phases separator having a first outlet and a second outlet, said phases separator comprising a septum or wall and a first chamber defined by an interior surface portion of said phases separator and said septum or wall, said septum or wall and another interior surface portion of said phases separator defining a second chamber having a closed top portion and an open bottom portion, said phases separator comprising a second connecting pipe, said second connecting pipe being disposed vertically in said second chamber, one end of said second connecting pipe being associated with said second outlet, another end of said second connecting pipe being located at a predetermined distance from said open bottom portion, said second connecting pipe being connected to said aspiration unit via said first connecting pipe, said phases separator comprising a container located at a position below said first outlet, said phases separator comprising a third connecting pipe, said container receiving a liquid phase of said fluid mixture via said third connecting pipe, said container having a lower opening;
• providing a pump connected to said lower opening of said container;
• providing injectors or atomizers disposed at a predetermined distance from said upper base of said phases separator;
• moving said liquid phase of said product mixture with said pump to said injectors or atomizers such that said liquid phase of said fluid mixture is reintroduced into said first chamber;
• providing a first tube;
• providing a second tube, said pump being connected to said lower opening via said first tube, said pump being connected to said injectors or atomizers via said second tube, said second tube having a second tube portion, said second tube portion extending through said upper base of said phases separator, wherein a portion of said second tube portion is located within said first chamber, said container having an upper side opening for removing liciuid not recycled by said pump;
• separating a liquid phase from a mostly gas phase of said fluid mixture;
• collecting at least a part of the liquid phase with said phases separator, wherein depolymerization and said separation of phases are carried out in a medium under vacuum.
