Step-by-step process integration method for the improvements and optimization of sodium tripolyphosphate process plant

Improvement and optimization of a complex chemical plant motivated by energy savings is presented in this paper. The reference object of the research is the sodium tripolyphosphate plant in ‘‘IHP-Prahovo’’, the biggest factory for producing chemical products in Serbia and Montenegro. The research is done by using a step-by-step process integration approach, which combines several computerbased simulation/optimization methodologies. The evaluation of obtained results indicates considerable possibilities for plant efficiency improvement.
