ABB, the leading power and automation technology group, announces Analyze IT PIR3502 process photometer, part of the total Industrial IT Solution for Sulfur Recovery Units. The ABB Analyze IT PIR3502 Process Photometer provides reliable monitoring of acid gas feed streams in refinery sulfur recovery plants. The fast response time of the photometer enables feedforward control of the main airflow valve to the combustion furnace.
Refinery hydrocarbon streams contain sulfur compounds as impurities that contaminate catalysts and cause operational problems. A hydrotreating process is used to convert any sulfur compounds present to hydrogen sulfide (H2S). The H2S from the hydrotreater is sent to a sulfur recovery plant to convert the hydrogen sulfide to elemental sulfur.
The measurement of one of these streams, the acid gas feed to the combustion furnace, enables feedforward control of the primary air valve. The combustion air requirement changes as the H2S concentration fluctuates in the acid gas fee stream.
The following components are measured with the PIR3502: Hydrogen Sulfide, Ammonia, Total Hydrocarbons, and Water Vapor in acid gas feed streams.
With careful control of the air flow in the combustion furnace provide the following benefits:
