ABSTRACT OF THE DISCLOSURE A method and system for reducing the oil concentration of a produced, hydrocarbon-containing fluid typically to no more than about 10 ppm and softening the deoiled fluid to reduce scale-forming constituents. The method and system are capable of treating fluids having a temperature above 100°C and typically within the range from approximately 120°C to approximately 160°C, without the need for cooling the fluid to perform either the deoiling step or the softening step. In a preferred embodiment, the deoiling step is performed by first filtering the hot fluid in a first set of coalescing filters and then in a second. identical set of coalescing filters, and the softening step is performed in a thermal softening unit wherein steam is directly sparged into the deoiled fluid in a reaction zone under pressure sufficient to prevent boiling at the reaction zone temperature.
