b) a transmix stream in fluid communication with the gasoline stream comprising distillate and a transmix flow rate; c) a blended stream comprising a combination of the transmix stream and the gasoline stream comprising a blended flow rate, a blended value for the physical property, and distillate; d) an IPU on which is stored the physical property limit, programmed to calculate a ratio or rate at which the transmix stream can be added to the gasoline stream based on the physical property limit and a measured value for the physical property of the blended stream; e) a sampler and a physical property analyzer at a sampling point on the blended stream in electronic communication with the IPU, electronically configured to withdraw samples from the blended stream, measure the physical property of the blended stream, and transmit or make accessible the measured physical property to the IPU; and f) a flow regulator interposed between the transmix and gasoline streams, in electronic communication with the IPU, electronically configured to receive or access the rate or ratio from the IPU and adjust the transmix flow rate without exceeding the rate or ratio. ### Claim 2 (depends on 1) The system of claim 1, wherein the gasoline stream comprises a plurality of batches selected from the group consisting of regular finished gasoline, premium finished gasoline, conventional blendstock for oxygenate blending, reformulated blendstock for oxygenate blending, premium blendstock for oxygenate blending, reformulated gasoline, and aviation gasoline. ### Claim 3 (depends on 1) The system of claim 1, wherein the gasoline stream comprises a plurality of batches of gasoline periodically separated by one or more batches of distillate. ### Claim 4 (depends on 1) The system of claim 1, wherein the gasoline stream comprises a plurality of batches of gasoline periodically separated by one or more batches of distillate, further comprising programming that causes blending to cease when distillate is passing the flow regulator. ### Claim 5 (depends on 1) The system of claim 1, wherein the transmix stream comprises greater than 5%, 10%, 20%, 35%, 50%, or 80% distillate. ### Claim 6 (depends on 1) The system of claim 1, wherein the transmix stream comprises greater than 50% distillate. ### Claim 7 (depends on 1) The system of claim 1, wherein the transmix is blended into the gasoline stream at a rate equal to or greater than 0.25%, 0.5%, 1%, 2%, or 3%. ### Claim 8 (depends on 1) The system of claim 1, wherein the transmix is blended into the gasoline stream at a rate equal to or greater than 0.5%. ### Claim 9 (depends on 1) The system of claim 1, wherein the distillate is selected from diesel fuel, marine fuel, aviation turbine fuel, non-aviation turbine fuel, heating oil, kerosene, and combinations thereof. ### Claim 10 (depends on 1) The system of claim 1, wherein the physical property is selected from octane, distillation temperature, Reid vapor pressure, sulfur concentration, and combinations thereof. ### Claim 11 (depends on 1) The system of claim 1, wherein the physical property comprises a combination of octane, distillation temperature, Reid vapor pressure, and sulfur concentration. ### Claim 12 (depends on 1) The system of claim 1, wherein said physical property is obtained by generating a spectral response of said gasoline stream, blended stream, and/or transmix stream using absorption spectroscopy with a near infrared analyzer, and comparing said spectral response to a chemometric dataset specific for said physical property in said gasoline stream, blended stream, and/or transmix stream. ### Claim 13 A method for blending off distillate transmix into a gasoline stream to produce a blended stream without violating a pre-determined limit on a physical property on the gasoline stream comprising: a) withdrawing samples periodically from the blended stream, measuring the physical property of the blended stream by an analyzer, and transmitting or making accessible via electronic communication the physical property measurement to an IPU; b) calculating on the IPU a ratio or rate at which the distillate transmix can be added to the gasoline stream based on the physical property limit and the physical property measurement of the blended stream;
