A system and process for the recovery of oil from the pyrolysis of material containing hydrocarbons such as shredded vehicle tires. The system utilizes a pair of sequentially positioned packed towers to recover at least 95% of the oil contained in the pyrolysis gases. The first packed tower operates above the dew point of the water vapor in the pyrolysis gases to insure that no water is condensed and obtain a primary oil fraction having oil with a high flash point of about 60° C. or greater and a primary vapor fraction containing additional oils, fuel gases and water vapor. The primary vapor fraction is fed to the second packed tower which operates below the dew point of the water vapor to condense the water and oil having a low flash point of 34° C. or below, and provide a secondary vapor fraction containing valuable fuel gases.

New and useful low viscosity polymeric colorant formulations are provided comprising extremely low amounts of viscosity modifiers that drastically reduce the overall viscosity of the resultant colorant formulation as compared with the viscosity of the colorants themselves. In such a manner, the resultant formulation facilitates the utilization of such polymeric colorants within certain coloring processes and methods requiring low viscosity formulations while simultaneously permitting substantial retention of the same high color strength characteristics of the unmodified colorants. Such an unexpected result thus permits production and utilization of a low viscosity formulation that does not sacrifice colorability to an appreciable degree for target substrates or media. The inventive formulations thus comprise any number of polymeric colorants, (i.e., oxyalkylenated colorants comprising at least one chromophore constituent and at least oxyalkylene chain) and at least one viscosity modifying agent possessing a dipole moment of between 1.0 and 5.0 and/or a flash point of from about -20° C. to about 180° C. Such a modifying agent provides a significant reduction in viscosity at low levels (to permit better pumpability of the desired colorants) with no appreciable differences in coloring performance within final target media, and facilitates removal of such modifiers during or after utilization. Methods of production, utilization, and products produced with such formulations and by such methods are also encompassed within this invention.
