APPARATUS FOR HANDLING AMMONIA-CONTAINING ACID GAS STREAMS

摘要

Refinery or similar streams containing NH3 are processed in a sulfur plant having separate burners for the NH3-containing acid gas stream and for the NH3-free acid gas stream. A sampling device is provided for continuously or periodically sampling the combustion products from the unit burning the NH3-containing gas. The H2S/SO2 ratios at this sample point and in the sulfur plant tail gas are used to control the operation of the system.
