Abstract: The amount of elemental sulfur or other sulfur contaminant picked-up by refined hydrocarbon product such as gasoline, diesel, jet fuel, kerosene or fuel additive such as ether, which is pipelined in a pipeline used to transport sour hydrocarbon fluids, is reduced by controlling the level of dissolved oxygen in the refinery hydrocarbon product to which is to be pipelined, said dissolved oxygen level being held to a level of about 30 wppm and less, preferably about 20 wppm and less. The dissolved oxygen level in the refined hydrocarbon product is controlled by reducing the amount fair injection employed in mercaptan or disulfide reduction production increases or by the use of oxygen scavengers prior to the introduction of the refined hydrocarbon product into the pipeline, or by limiting the exposure of the product to air in oxygen during transport or storage.

Abstract: Disclosed is a deicing device for deicing cables. The deicing device includes one pair of conductive wires connected to and helically wound along the cable. The conductive wires are connected at one end to a pulsing device which generates an electromagnetic pulse within the wires, and are connected together at the other end. Upon a passage of the electromagnetic pulse in the wires, a repulsive force is created between the wires, which shakes the wires and shatters the ice that may be attached to the cable.
