View Diary: Canadians Import Texas Oil Instead of Building a Pipeline East, Fear Spills (61 comments)

  •  A couple of important points (6+ / 0-)

    ---Refineries can only process the type of crude oil that they are built to process.  They can be changed to process other crudes, but that costs millions.  The Texas refineries are currently built to process the very heavy crude from Venezuela, and apparently the diluted bitumen from Alberta will work there.

    ---Interesting info about the toxicity of the dilutent required to pump the bitumen from Alberta.

    ---Very heavy crude oils do have a specific gravity heavier than water.  They will sink in water whether they are "crude oil" or "bitumen."

    •  According to the lengthy dilbit story (6+ / 0-)

      The dilbit has a specific gravity just under one. It barely floats at first, but the light components evaporate and  it gloms on to sediment and sinks.

      look for my eSci diary series Thursday evening.

    •  API 10 or under, it sinks. (3+ / 0-)

      •  API is the inverse of specific gravity (0+ / 0-)

        API 10 = specific gravity 1.00

        API numbers get lower as the oil gets more dense, so API numbers under 10 also sink, and the lower the number, the quicker it sinks.

        Specific gravity compares oil density to the density to water, so a specific gravity of 1.00 is the same density as water, and a slightly lower specific gravity would float. Oil with a higher specific gravity would sink, since that means the oil is more dense than water. With specific gravity, the higher the number, the quicker it sinks.

    •  Oddly (0+ / 0-)

      The Koch Bros. refinery in Corpus Christi has an application currently pending to add $1 Billion in equipment to process Eagle Ford crude, rather than Tar Sands crude.

      Orly, it isn't evidence just because you downloaded it from the internet.
