Abstract: Disclosed herein is a method for treating hydrocarbon fluids to inhibit the deposition of paraffin compounds on the interior of pipes and other surfaces. The method includes injecting a catalyst fluid containing scale forming compounds into the hydrocarbon fluid. The scale forming compounds may be calcium carbonate, calcium bicarbonate, calcium, bicarbonate barium sulfate, or other compounds/ingredients. The catalyst fluid may be an aqueous or non-aqueous solution. The method further includes inducing an electromagnetic field in the fluid so as to cause the formation of seed crystals from the scale forming compounds. The paraffin will then adhere to the seed crystals, i.e., scale particles. The resulting particles can then be filtered out or otherwise removed from the solution. Paraffin deposition on the interior of pipes and other surfaces is therefore inhibited. Also disclosed herein are hydrocarbon wells and other piping systems constructed to take advantage of the described techniques.

Abstract: The disclosed systems and methods for maintenance of an enclosed body of water generally include mobile systems and/or methods for removal of mineral hardness and other particulate impurities via lime softening filtration. Chemicals are added to a body of water containing unwanted mineral hardness (or other particulate impurities) and mixed to assist dispersion.

This eliminates or otherwise reduces the need for draining water and/or adding new water to a body of water to maintain proper mineral hardness balance and/or concentration of other particulate impurities.

Abstract: An improved method for isolating the impacts of flow-altering events in corrosion transport from those due to steady state corrosion in boiler/steam cycle processes. The method includes monitoring, in real time, with a particle counter or particle monitor levels of suspended particles in a fluid flow stream and of automatically collecting insoluble particulates large enough to be captured on a 0.45 micron filter when, and only when, these levels exceed an “event threshold”. For use in subsequently characterizing flow-altering events without necessarily weighing the collected particulates for each excursion above this threshold, an average particle count/particle index is obtained and compared with the actual weight of insoluble particulates captured. When excursions are highly infrequent, concentrations of insoluble metal oxides likely to be present in the flow stream and capable of producing above-threshold PC/PIs can be determined and used to identify anomalies when particulates are captured.

Abstract: In a first treatment step part of at least one difficulty biodegradable or non-biodegradable organic compound is oxidized in polluted water by bringing said polluted water into contact with an ozone containing gas. The effluent is subsequently diluted with an aqueous liquid before a second treatment with ozone is carried out.

It was found that a more effective ozone treatment was obtained by the dilution or dilutions and that in particular no pH control was needed, so that no formation of additional salts occurred.
