Abstract
Refinery or similar streams containing NH.sub.3 are processed in a sulfur plant having separate burners for the NH.sub.3 -containing acid gas stream and for the NH.sub.3 -free acid gas stream. A sampling device is provided for continuously or periodically sampling the combustion products from the unit burning the NH.sub.3 -containing gas. The H.sub.2 S/SO.sub.2 ratios at this sample point and in the sulfur plant tail gas are used to control the operation of the system.
