Optimisation of a condensate recovery system

Abstract

In the past few years the energy demand in the world kept on increasing year by year. The part that will be focused is the designing of the condensate recovery system to optimise the system is how much condensate should be recovered and at what is the usage of equipment need in the designing of the equipment with the cost. The problems that will be addressed are minimising the cost of make-up water and energy. Suitable design based on the condensate condition of the condensate presence in the system is addressed also. In pharmaceutical industries, around 35 to 70 per cent of the condensate along with significant quantity of heat is being drained to the effluent treatment plant (ETP). Two objectives is considered in this research which is to develop an optimisation model of a condensate recovery system, with the objective of maximising the economic potential and to apply model on a case study to determine potential savings of condensate recovery system. The scope started with the data collection on the condition of the condensate based on the case study then proceed with the designing of each piping, pump and system type equipment. Then he parameters to design the system such as what time of systems, pumps and piping will be calculated and used in the construction of the superstructure. Then the formulation of the optimisation of the thermal energy system is formulated. Then the data will be input into the formulation and run it into GAMS modular software. Then the results are recorded and see how much energy is conserved and how much of the system is optimised. The modelling optimisation was successful and the maximum economic potential was recorded. The pipe, pump and system type were chosen the optimal in this case study. The conclusion in this research is the optimisation of the condensate recovery system economic potential is at 128915 $. This research can contribute to the reduction of energy demand in the thermal energy system.
