LNG FRACTIONATION TECHNOLOGY

Ortloffs LNG fractionation technology for the recoveryof NGL / LPG at LNG receiving terminals offers the

following advantages:

Flexibility to handle wide range of LNG composition

Improved plant efficiency by utilizing inherent refrigeration available

in LNG

No increase in heat load on vaporization

Minimizes plant capital and operating costs over traditional straddle

plant design Recovery of liquids easily adjusted to meet natural gas pipeline

heating value specifications

Requires no compression

Easily retrofitted into an existing facility

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
