1. A method for conditioning synthetic crude oil, the method comprising: providing synthetic crude oil obtained by pyrolysis of one or more materials selected from polymer, plastic, and rubber materials;providing an aqueous process solution, wherein the aqueous process solution is a caustic process
1. A method for conditioning synthetic crude oil, the method comprising: providing synthetic crude oil obtained by pyrolysis of one or more materials selected from polymer, plastic, and rubber materials;providing an aqueous process solution, wherein the aqueous process solution is a caustic process solution and exhibits a pH of between about 8 and about 10;mixing a first volume of the synthetic crude oil with a second volume of the process solution, wherein the first volume of the synthetic crude oil is less than the second volume of process solution;delivering the mixture of the first and second volumes to a separator where conditioned synthetic crude oil is extracted from the mixture; andcollecting the conditioned synthetic crude oil from the separator. 2. The method of claim 1, further comprising filtering the synthetic crude oil by passage of the synthetic crude oil through a filter media capable of capturing solid particulate material entrained within the synthetic crude oil and wherein mixing the first volume of the synthetic crude oil with the second volume of the process solution comprises: providing a mixer suitable for mixing the synthetic crude oil and the process solution;determining the first volume of synthetic crude oil to be delivered to the mixer;calculating the second volume of process solution to be delivered to the mixer based on the first volume of synthetic crude oil; andmixing the first volume of synthetic crude oil with the second volume of process solution. 3. The method of claim 2, wherein delivering the mixture of synthetic crude oil and process solution to the separator comprises delivering the mixture to a separation tank and holding the mixture within the separation tank for a period of time sufficient to allow separation of the conditioned synthetic crude oil from the process solution. 4. The method of claim 3, wherein delivering the mixture to separation tank comprises delivering the mixture through a diffuser assembly within the separation tank. 5. The method of claim 2, wherein delivering the mixture of synthetic crude oil and process solution to the separator comprises delivering the mixture to a separator comprising a separation tank comprising one or more weirs and separating the conditioned synthetic crude oil from the process solution is accomplished by serial passaging of the mixture of synthetic crude oil and process solution into and through the one or more weirs. 6. The method according to claim 2, wherein the process solution exhibits a pH of between about 9 and about 10. 7. The method of claim 5, further comprising: collecting separated process solution from the separation tank; andrecirculating the separated process solution for reuse in conditioning additional amounts of synthetic crude oil. 8. The method of claim 7, wherein recirculating the separated process solution comprises passing the separated process solution through one or more strainers. 9. The method of claim 7, wherein, prior to reuse of the separated process solution, the process solution is analyzed and brought to a pH selected from one of a pH of between about 8 and about 10, a pH of between about 9 and about 10, and a pH of about 9.5 prior to being mixed again with synthetic crude oil. 10. The method of claim 1, wherein the ratio of the first volume to the second volume is selected from a range of above 1:1-1:200, 1:2-1:200, 1:3-1:200, and 1:4-1:200. 11. The method of claim 1, wherein the ratio of the first volume to the second volume is selected from a range of 1:2-1:100, 1:2-1:50, 1:2-1:25, 1:2-1:10, and 1:2-1:5. 12. The method according to claim 6, wherein the process solution is an aqueous solution comprising a soluble caustic selected from the group consisting of potassium hydroxide (KOH), calcium hydroxide (Ca(OH)2), cesium hydroxide (CsOH), Barium hydroxide (Ba(OH)2), sodium hydroxide (NaOH), strontium hydroxide (Sr(OH)2), and lithium hydroxide (LiOH). 13. The method of claim 2, wherein the synthetic crude oil and the mixture of synthetic crude oil and process solution are maintained at a temperature within a range of about 100° F.-175° F. throughout the conditioning process. 14. The method of claim 13, wherein the synthetic crude oil and the mixture of synthetic crude oil and process solution are maintained at a temperature within a range of about 110° F.-160° F. throughout the conditioning process. 15. The method of claim 2, wherein filtering the synthetic crude oil comprises passing the synthetic crude oil through filter media capable of capturing entrained particulates exhibiting a size selected from the group consisting of 500 μm or less, 200 μm or less, 100 μm or less, 50 μm or less, 25 μm or less, 10 μm or less, 5 μm or less, and 1 μm or less. 16. A method for conditioning synthetic crude oil, the method comprising: providing synthetic crude oil obtained by pyrolysis of one or more materials selected from polymer, plastic, and rubber materials;filtering the synthetic crude oil by passage of the synthetic crude oil through a filter media capable of capturing solid particulate material entrained within the synthetic crude oil;determining a first volume of synthetic crude oil to be delivered to a mixer;calculating a second volume of process solution to be delivered to the mixer based on the first volume of synthetic crude oil, wherein the aqueous process solution is a caustic process solution and exhibits a pH of between about 8 and about 10, and wherein the first volume of synthetic crude oil is less than the second volume of process solution;after filtering the synthetic crude oil, mixing the first volume of synthetic crude oil with the second volume of process solution;delivering the mixture of the first and second volumes to a separator wherein conditioned synthetic crude oil is extracted from the mixture; andcollecting the conditioned synthetic crude oil from the separator.
