摘要： A cross-flow filtration system includes a first filter element having a first conduit for receiving a flow of a first aqueous feed stream, a second conduit operable to discharge a flow of first permeate water and a third conduit operable to discharge a flow of first retentate water. The cross-flow filtration system includes a coil assembly disposed about the first conduit. The first coil assembly is operable to subject the first aqueous feed stream to electromagnetic pulses. A second filter element is in fluid communication with the first filter element via the third conduit. The second filter element is operable to receive the first retentate water via the third conduit. A second coil assembly is disposed about the third conduit and is operable to subject the first retentate water to electromagnet pulses.

摘要： A fluid feed stream is flowed, subject to electromagnetic pulses, to a filter element via an input feed conduit for the filter element. A coil assembly is disposed about the input feed conduit and an AC power source is connected with the coil assembly. The AC power source has a period including first and second half-cycles of opposing polarities. A switch in series with the coil assembly forms a series connected circuit. A second switch connected with the coil assembly forms a second circuit. A control means closes the first switch and opens the second switch during a first half-cycle of the AC power source. During a second half-cycle, the control means closes and then opens the second switch to produce a first large ringing pulse in the coil assembly. A subsequent pulse may be produced either before or after the first pulse substantially decays.

摘要： A coating applied to at least a portion of the surfaces of reactors, reactor internals, other reactor components, and/or heater tubes is provided in order to minimize the formation of metal catalyzed coke in hydrocarbon conversion processes operating at temperatures at about 350° C. (662° F.) or greater and in reducing environments. These coatings may comprise Nickel coatings or complexes thereof, such as Ni—Al, Ni—Cr/Cr carbide, as well as aluminum painted coatings that are applied in a reduction cure process (e.g., application temperatures of about 600° C. (1112° F.)). Additionally, where H2S is necessary for the process, such as to minimize thermal cracking, the coatings also reduce corrosion of base metal due to sulfidation attack and eliminate the requirement of continuous replacement of reactor internals and other components.
