Problem 2 Mercaptans, hydrogen sulfide, and other sulfur compounds are removed from natural gas by various so-called “sweetening processes” that make available otherwise useless “sour” gas. As you know H2S is toxic in very small quantities and is quite corrosive to process equipment. A proposed process to remove H2S is by reaction with SO2 H2S (g) + SO2 (g) → S (s) + H2O (g) In a test of the process, a gas stream containing 20% H2S and 80% CH4, was combined with a stream of pure SO2. The process produced 156 lb-mol of S(s), and in the product gas the ratio of SO2 to H2S was equal to 3, and the ratio of H2O to H2S was 10 a) Write the balanced reaction. b) Calculate the amount (Ib-mol) of H2S and SO2 in the feed. is in excess. d Determine the amount of product fomed (lb-mol) and its composition Product P 20% H2S–+ 80% CH4 ngoa nizs nH2o nCHa Reactor SO2 156 Ib-mol

(a) For the line l in R2 given by the equation ax + by = d, find a vector v that is parallel to l. (b) Find a vector n that is normal to l and has first component equal to a. (c) If P0(x0, y0) is any point in R2 , use vectors to derive the following formula for the distance from P0 to l: To do this, you’ll find it helpful to use Figure 1.115, where P1(x1, y1) is any point on l. (d) Find the distance between the point (3, 5) and the line 8x − 5y = 2.
