As conclusion to the scaling-up from a pilot plant designed, constructed and operated with this purpose an industrial plant project was started. This plant should show flexibility in both production capacity and raw material type. Conceptual engineering which comprised design basis ; process steps, production capacity, operative variable ranges, flux type, specification of construction materials, raw specifications, auxiliary materials, instrumentation and control type, were developed. Basic engineering comprissing equipment and auxiliary components specification of: CO2 entrance, pumping and pressurization, thermal conditionning, extraction, fluid- extract separation, flow temperature and pressure meassure and control, is in the lates steps. Detail engineering of different capacity extractors has been started at this point.
Liquid CO2; extraction plants; subcritical extraction; extrator projects
