Heat Transportation System From Steelworks to Chemical Plants
This paper describes the feasibility of the latent heat transportation system using Phase Change Material (PCM) to recover waste heat at high temperature in the steelworks and to supply the recovered heat to chemical plants such as BTX plants. Candidates of PCM for the system were determined experimentally. Moreover, the proposed system was theoretically analyzed from three viewpoints-energy requirement, exergy loss and CO2 emissions and compared to the conventional heat supply system and the sensible heat transportation system under reasonable assumptions. As a result, NaOH or its based materials were the best PCM candidates for the system from phase change point, latent heat and cost. The system analysis shows the latent heat transportation system using 17.1wt%Na2CO3-82.9wt%NaOH as PCM has 2.16 times larger in heat storage density than that in the sensible heat transportation system and compared to the conventional system without heat recovery, this system has only 7.6% in energy requirement, 31.4% in exergy loss and 16.3% in CO2 emission. The results appealed a new possibility of heat transportation between different industries using PCM for high temperature application.
