Blow Out Preventer Detail BP technical briefing and update on Gulf of Mexico oil spill 10 May 2010 Tony Hayward Failure of the Large Dome: A lot more gas involved in leak than previously believed. Moving to a smaller dome … Continue reading
Liquid carbon dioxide forms only at pressures above 5.1 atm; the triple point of carbon dioxide is about 518 kPa at -56.6 °C. The critical point is 7.38 MPa at 31.1 °C. Plumbers use equipment that forces pressurised liquid CO2 … Continue reading
Oil freezes -18 Celcius (motor oil), diesel -30 C, Cuide Oil -31 F (-35 C) Kind of temperatures you’ll get with dry ice (-78°C) or even liquid nitrogen (-196°C) Olive oil: 6C (refrigerator temp) Sunflower oil: 17C Aviation gasoline: -60C … Continue reading
Water freezes at a temperature below 0 °C under a pressure higher than 1 atm (0.10 MPa). Consequently, water also remains frozen at a temperature above 0 °C under a pressure lower than 1 atm. The melting of ice under … Continue reading
The freezing temperature of salt water depends on how much salt you put in. Oceanographers define the “salinity” of water as the number of grams of salt per 1000 grams of water. (Since 1000 grams of water is almost exactly … Continue reading
The density of surface seawater ranges from about 1,020 to 1,029 kg•m−3, depending on the temperature and salinity. Deep in the ocean, under high pressure, seawater can reach a density of 1,050 kg•m−3 or higher.
Here is a phase diagram of Carbon Dioxide (CO2): Phase diagram of ice:
The density of dry ice varies, but usually ranges between about 1.4 and 1.6 g/cm3 (87–100 lb/ft3). Dry Ice, solid C02 would therefore sink to the bottom in salt water.
The density of fresh water ice is 0.92 g/mL.
Maximum ice-crushing strengths averaged from about 475 lb/in2 at the White River near Oacoma/Presho site to about 950 lb/in2 at the James River at Huron site. See this pdf for additional information on the ice cores taken from South Dakota … Continue reading
Q. How was the $20 billion number for the compensation package established? A. Negotiation with the government. Nervousness with the cap of liability of $75 million based on oil and gas law of 1995. BP has assured that all the … Continue reading
The static pressure caused by a fluid varies with depth according to: P = ρ gh where: P is the pressure in pascals; 1 pascal = 1 newton /meter2 ρ is the density of the fluid in kilograms /meter3 g … Continue reading
Here are some images of the small top hat that is currently being used to recover around 11,000 barrels of oil in a twelve hour period (ranges vary from 7,780 to 14,570 barrels).
Seawater is denser than fresh water because of the salts’ added mass. The freezing point of sea water is about -2 ºC. Deep in the ocean, under high pressure, seawater can reach a density of 1,050 kg•m−3 or higher. From … Continue reading
Use the methane hydrates that blocked the flow of oil in the first dome to freeze the BOP preventer and liquid inside the containment dome. Instead of having this be a hinderance for the subsea leak stopping, use it to … Continue reading
This chart shows the design, depth, diameter, and temperature of the Macondo Well where the oil from the BP oil spill is leaking from. PDF of Macondo Well
Molecular Weight Molecular weigh of CO2: 44.01 g/mol Molecular weight of H2O: 18.02 g/mol My approximation of the Molecular weight of Sea Water: 17.387 g/mol (????).
The nuclear explosion was used as a last resort after a gas-well blaze lasted for three years. The incredible heat was a main deterrent in bringing the flame under control. The nuclear bomb was put down a drill shaft below … Continue reading
