Integration of plastic recycling and oil extraction processes

Abstract

The present disclosure pertains to the technical field of recycling of plastic wastes. In particular, the present disclosure provides an integration of a plastic recycling process into plants that produce extra heavy oil, especially plants producing oil from oil sands. Further, the present disclosure provides a process for providing hydrocarbon streams to an oil sands processing facility from plastics pyrolysis, wherein, the plastic pyrolysis is performed in a plant integrated into the oil sands processing facility. Also, the overall process is environment friendly, energy efficient and economical.

We claim: 
     
         1 . An integration of plastic recycling and oil extraction processes, comprises of providing hydrocarbon streams obtained from plastic pyrolysis to an oil sands processing facility, wherein, the plastic pyrolysis is performed in a plant integrated into the oil sands processing facility. 
     
     
         2 . The process as claimed in  claim 1 , wherein the oil sands processing facility is the central processing facility (CPF) of a SAGD plant, CSS plant or an upgrader. 
     
     
         3 . The process as claimed in  claim 1 , wherein the integrated plastic pyrolysis plant provides one or more hydrocarbon streams to the oil sands processing facility. 
     
     
         4 . The process as claimed in  claim 1 , wherein the hydrocarbon streams are selected from the group consisting of diluent, synthetic crude oil and trim solvents (butane, fuel gases) or a combination thereof. 
     
     
         5 . The process as claimed in  claim 1 , wherein the plastic feedstock for pyrolysis is selected from post-consumer use or industrial waste such as municipal, construction, manufacturing or agricultural waste. 
     
     
         6 . The process as claimed in  claim 1 , wherein the integration of the plastic pyrolysis process into the oil sands processing facility involves sharing streams such as natural gas and other gaseous fuels between the plastics pyrolysis process and the oil production facility. 
     
     
         7 . The process as claimed in  claim 1 , wherein the integration of the plastic pyrolysis process into the oil production facility involves sharing utilities such as electric power, steam and cooling fluids. 
     
     
         8 . The process as claimed in  claim 1 , wherein the integration of the plastic pyrolysis process into the oil production facility involves sharing safety systems such as leak detection and fire suppression. 
     
     
         9 . The process as claimed in  claim 1 , wherein the plastic pyrolysis plant design, operating conditions and feedstock choice is optimized to provide the optimal blend of output products for the oil sands processing facility. 
     
     
         10 . The process as claimed in  claim 9 , wherein the output products include diluent, synthetic oil and trim solvents (butane, fuel gases). 
     
     
         11 . The process as claimed in  claim 9 , wherein the plastic pyrolysis plant design is modularly expandable.
