    摘要： An electrochemical cell apparatus and method comprising a first electrode and a second electrode wherein the area ratio between them is 15 or higher, for example a metal plate and a metal wire; wherein said first and second electrodes are made from the same material; and wherein the distance between said first electrode and said second electrode is in the range of from about 1 mm to about 1 μm is provided. Such electrochemical cell can be used to measure crude oil corrosion using an electrochemical impedance method.

    摘要： A system and process for removing water and heteroatom-containing compounds from hydrocarbons and for regenerating the adsorbent used in the system and process is disclosed and includes contacting the hydrocarbon stream with a water adsorbent and a heteroatom-containing compound adsorbent. The regeneration includes passing an isoparaffin over the water-adsorbent, then passing the isoparaffin over the heteroatom-containing compound adsorbent; and, optionally; cooling the effluent; separating such into a hydrocarbon phase and a water phase in a settler; removing a portion of the hydrocarbon phase for mixing with water; returning the hydrocarbon/water mixture to the settler; removing some of the hydrocarbon phase from the settler to form a recycle isoparaffin stream for use as a portion of the stripping stream; and removal of a portion of the water phase from the settler to form a waste water stream containing water and heteroatom-containing compound.
