Abstract: A fluid analyzer includes an optical source and an optical detector defining an optical beam path through an interrogation region of a fluid flow cell. Motion control devices determine position of the interrogation region.

A controller (1) generates a time-varying motion modulation signal to move the interrogation region across the fluid boundary, (2) samples an output signal from the optical detector at one time in which the interrogation region contains more analyte fluid than reference fluid and at a time at which the interrogation region contains more reference fluid than analyte fluid, thereby generating corresponding output signal samples, and (3) determines from the output signal samples a measurement value indicative of an optically measured characteristic of the analyte fluid.

Abstract: A system for a Fischer-Tropsch synthesis using a three-phase reactor in which a primary filter removes coarse catalyst particles from the product and in which catalyst fines are removed in a secondary filter. Some or all portion of the product wax from the secondary filter can be recycled back to the reactor, either as a back flush medium for the primary filter or directly to the slurry in the reactor, whereby removal of catalyst fines is rendered independent of the rate of wax production.
