1. A method of monitoring and controlling a dehydrogenation reactor system wherein said dehydrogenation reactor system comprises a plurality of reactors and heaters with said heaters positioned upstream from each reactor and a hydrocarbon feed stream being heated by each of said heaters and undergoing reactions in said reactors, said method comprising:
a. removing a sample of the hydrocarbon feed stream prior to an inlet and an outlet of said heaters;
b. comparing compositions of a sample to a predetermined composition range;
c. taking at least one action to modify operation of said dehydrogenation reactor system when said composition of a sample varies more than a predetermined amount from said predetermined composition range.
