Coal gasification electric power plants...
Coal gasification electric power plants are now operating commercially in the United States and in other nations. This technology produces clean-burning hydrogen that can be transferred to customer facilities by pipeline. Hydrogen can also be transported in bulk by highway or rail. If there is aspill of liquid hydrogen, why will it likely burst into flame spontaneously? Why do experts recommend the use of a thermal-imaging camera for detecting a hydrogen leak from a pipe fitting connected to a steel cylinder of hydrogen? Your total response must be at least 200 Sulfur is one of the world's most important raw materials. Fires involving sulfur pose some unique hazards. Why are secondary fires likely to result near burning bulk quantities of sulfur? What precautions should be taken to prevent these secondary fires?
What are the two common allotropes of sulfur? Discuss some commercial uses of sulfur. Your total response must be at least 200 words in length. Meyer, E. (2014). Chemistry of hazardous materials (6th ed.). Upper Saddle River, NJ: Pearso
According to a standard reference table, the R value of a 3.5inch-thick vertical air space (within a wall) is 1.0 (in English units), while the R value of a 3.5-inch thickness of fiberglass batting is 10.9. Calculate the R value of a 3.5-inch thic..
Calculate the total degrees of freedom over the entire process. Next, calculate the degrees of freedom around each unit operation. Label all calculations.
