Early SRU Experience
Designed / built 7 SRUs for sister company in 1960s
Little design information available
SRUs suffered typical reliability problems Sulfur plant reliability affects profitability
Began analyzing reliability problems in 1969
Developed design concepts to improve reliability
Further improvements have been on-going
Concepts used in all Ortloff plants since 1970
The Ortloff Corporation (1960 1985) Designed / constructed 53 SRUs
Ortloff Engineers, Ltd. (1986 Present)
Designed 30 SRUs constructed by others
