Western Canada, one of the richest sulfur-producing areas in the world, produces over 15,000 metric tons per day of petroleum-derived sulfur, and has over 60 sulfur recovery plants with a combined sulfur production design capacity of over 30,000 metric tons per day. Emerson Process Management has performed the instrumentation and control system engineering through startup on many of those plants, ranging from 10 metric tons per day to 3,000 metric tons per day. Emerson Process Management expertise includes:

• Two stage and three stage Claus process
• Super Claus process
• Scot tailgas cleanup process
• Sulfreen process
• MCRC process
• ELSE process
• Implementation of pressure- and temperature-compensated air to acid gas ratio control
• Implementation of air demand analyzers for control of air trim valves or, on small plants, biasing the air/acid gas ratio
• Stoichiometric control of reheat burners in the first, second, and third reaction stages of sulfur plants
• Burner management for reaction furnaces and reheat burners

In addition to sulfur recovery control system expertise, Emerson Process Management has considerable expertise in related areas including:

• Sour gas and H2S safety and shutdown systems
• Sulfur loading control and measurement
• Sour gas pipeline monitoring, control, leak detection, and safety shutdown
• Sour gas well production monitoring and control
