Modular construction accounted for in design

for ease of installation

A Costain process design was used incorporating a turboexpander/compressor system to generate the necessary refrigeration by utilising the pressure energy available in the feed gas.

High liquids recovery is achieved with very low supplementary power input.

Following the concept phase, Costain was awarded the contract to carry the design forward through detailed design, module design and supply plus supervision/inspection of module construction for site delivery.
