3.16. In April 2010, the worst oil spill ever recorded occurred when an explosion and tire on the Deepwater
Horizon offshore oil-drilling rig left 11 workers dead and began releasing oil into the Gulf of Mexico. One of the attempts to contain the spill involved pumping drilling mud into the well to balance the pressure of escaping oil against a column of fluid (the mud) having a density significantly higher than those of seawater and oil. In the following problems, you may assume that seawater has a specific gravity of 1.03 and that the subsea wellhead was 5053 ft below the surface of the Gulf.
- Estimate the gauge pressure (psig) in the Gulf at a depth of 5053 ft.
- Measurements indicate that the pressure inside the wellhead is 4400 psig. Suppose a pipe between the surface of the Gulf and the wellhead is filled with drilling mud and balances that pressure. Estimate the specific gravity of the drilling mud.
- The drilling mud is a stable slurry of seawater and barite (SG = 4.37). What is the mass fraction of barite in the slurry?
- What would you expect to happen if the barite weight fraction were significantly less than that estimated in Part (c)? Explain your reasoning.

- Propane is burned completely with excess oxygen. The product gas contains 24.5 mole% CO2, 6.10% CO, 40.8% H2O, and 28.6% O2. (a) Calculate the percentage excess O2 fed to the furnace. (b) A student wrote the stoichiometric equation of the combustion of propane to form CO2 and CO as: 2C3H8 + 11O2 → 3CO2 + 3CO + 8H2O According to this equation, CO2 and CO should be in a ratio of 1/1 in the reaction products, but in the product gas of Part (a) they are in a ratio of 24.8/6.12. Is that result possible? (Hint: Yes.) Explain howarrow_forwardEnumerate the various methods for catalyst preparation and discuss vividly any one of the methodsarrow_forward2. Design a spherical tank, with a wall thickness of 2.5 cm that will ensure that no more than 45 kg of hydrogen will be lost per year. The tank, which will operate at 500 °C, can be made from nickel, aluminum, copper, or iron (BCC). The diffusion coefficient of hydrogen and the cost per pound for each available material is listed in Table 1.
