Abstract: A fouling test apparatus comprising a cylindrical pressure vessel, means for controlling the temperature of fluid contained in the vessel, cylindrical probe having a metallic surface concentric with the vessel walls and provided with a heater for such surface; stirrer in the form of a rotor open at at least one end and positioned between and concentric with the vessel walls and the probe, and sensor for measuring the temperature of the fluid contained in the vessel and the temperature of the probe surface. The probe simulates a heat exchanger surface exposed to a fouling liquid medium. Deposits accumulate on the heated surface in a similar fashion to an actual system and the parameters which affect fouling are all represented. The probe operates with a constant heat flux. As deposits accumulate, the surface temperature of the probe increases and is used as a measure of the deposit formation. The probe is maintained in a stationary position and the stirrer is not dependent on an electrical feed-through.

Abstract: A desalter/dehydrater having a plurality of electrified coalescing stages in a single vessel wherein the stages are isolated hydraulically to allow parallel or serial stage operation and the emulsion being treated is introduced at one side of the vessel and caused to flow to the opposite side between horizontal planar permeable electrodes. In one embodiment, several electrical stages are operated in parallel to increase vessel throughput capacity. In another embodiment, series operation is employed, wherein each successive stage receives the product from the preceding stage as feed, with fresh water being added. The number of stages is one less than the number of the electrodes.

Abstract: Cathodic protection monitoring of large metallic structures receiving cathodic current from a remote anodic electrode. Exposed to the cathodic current, closely adjacent the metallic structure, is a metallic specimen with a surface area of less than one-tenth of the structure's area. Current flow is induced between the specimen and the structure until their potential difference is substantially zero. Measurement of the induced current flow allows the current density impressed upon the specimen to be determined, and it is substantially identical to the current density impressed upon the structure by the cathodic current. Anodic and cathodic induced current flows are employed for varying the potential of the specimen relative to the structure (as reference) to determine anodic and cathodic reaction rates, unprotected corrosion rate of the structure, and the cathodic current required to protect the structure. The metallic specimen may be partially encased in an insulating covering.
