A method for analysing a blend of two or more hydrocarbon feed streams such as crude oils. These crude oils are blended in a facility such as a refinery. The method assesses the compatibility of a hydrocarbon feed in a blend to calculate the blend stability such that organic deposition is minimised. The method selects a neat hydrocarbon feed, from the plurality of hydrocarbon feeds included in a blend, as a titrant, wherein the or each other hydrocarbon in the hydrocarbon feed are used to make a pseudo-blend. The method titrates the pseudo-blend with said selected neat hydrocarbon feed for a plurality of different blend ratios, measures and records data associated with the change in characteristics of the titrated blend and calculates, using said data, the stability of the blend. |
