The payback time of the steam turbine upgrade is usually in the order of 1 year. Costs can be reduced by including the upgrade in the normal turn-around schedule. The cost for upgrading two back-pressure turbines with more efficient condensing turbines in an ammonia plant in the US estimated to require an investment of $ 1.2 million (U.S. DOE, 2007)
