REVIEW QUESTIONS AND EXERCISE PROBLEMS
1. Name the main categories of the sweetening processes.
2. What constituents from natural gas are removed by the sweetening
process?
3. What is the difference between ‘‘acid gases’’ and ‘‘sour gases’’?
4. The sulfinol process is an example of:

(a) Physical
(b) Dry bed
(c) Chemical
(d) Chemical/physical (hybrid).

5. Some sweetening processes have a ‘‘dual function’’; they bring in gas
dehydration as well. Which of the following sweetening processes fall
into this category?

(a) MEA
(b) DGA
(c) DEA
(d) Sulfinol
(e) Molecular sieves.
6. A sour crude oil contains 1.2 SCF of dissolved H 2 S per 1000 gallons
of crude oil. If the buyer’s specs for crude oil is 50 ppm maximum,
calculate:
(a) The H 2 S content of the sour crude oil in ppm
(b) The amount of H 2 S gas (SCF) to be removed per 1000 bbl of oil in
order to meet the specs.
7. Why is the selective removal of H 2 S with respect to CO 2 in some
special cases desirable?
