PULPA CUBA MILL ENERGY ASSESSMENT

Abstract

An energy study was performed at Pulpa Cuba Paper Mill, located in Sancti Spiritus,  where an energy management system was applied according to NC: ISO 50001, in order  to assess the energy system by applying energy management systems for energy and  water reduction in the paper mill, in which the current steam generation, distribution  and consumption system is diagnosed. The proposal of a modified energy scheme with  1 MW Backpressure Steam Turbine Generator and rehabilitation of the original boiler  or installing a lower capacity boiler contributes to save financial resources by the  concept of water, fuel and electricity. The implementation of four projects will save  3,095,574 CUC / y and an average payback period of about 1 year is expected.
