Abstract
This project work was done to ascertain the economic viability of separating NGLs
into individual components as oppose to mix product such as LPG using the Ghana
National Gas Company Processing Plant as a case study. The process flow diagram of
the gas processing plant was reviewed to incorporate a depropanizer to recover propane
and a butane splitter to recover isobutane and normal butane. The depropanizer and the
butane splitter were sized using the procedure recommended by the Gas Producers and
Suppliers Association and cost- benefit analysis conducted using Net Present Value
approach the results of which showed that the project was viable. It was recommended
that the material balance and the design parameters obtained should be confirmed by the
use of a process modeling software and sensitivity analysis be conducted on the cash
flow.
