Abstract

Giammarco-Vetrocoke (GV) has elected for its low energy system, the adoption of two strippers one operating at higher pressure (HP) and the second at lower pressure (LP). The solution flowing from HP to LP is developing flashing steam which heat content represent the energy gain of the system. The plants originally designed with two twin-parallel strippers are excellent candidates for revamping to GV low-energy process which entails the minimum cost of disruption because all that is needed is some modification to the piping lay-out. Energy saving up to 40% has been already achieved with the proposed revamp scheme.
