TL;DR: In this paper, a new method is proposed to simultaneously determine the working fluid and operating conditions in an ORC system, which recovers this type of waste heat in refineries, based on a newly defined parameter (PREDICTOR) that can predict the Pinch position between the waste heat carrier and working fluid accurately, calculate the mass flow rate of working fluid, and the amount of heat recovered easily.

TL;DR: In this paper, the authors compared the performance of ORC and Kalina cycles for heat recovery from a single heat source or stream in the process industry, and showed that for straight and concave waste heat with maximum supply temperature 180°C, Kalina cycle is better than ORC.

TL;DR: In this article, a combined heat integration method is proposed, which involves the characteristics of both direct method and indirect method, and the performances for heat integration across plants using direct, indirect and combined methods are analyzed and compared through Composite Curves.

TL;DR: In this article, the performance of an ORC system is strongly related to the working fluid and therefore, working fluid selectors select the optimal ORC cycle for low temperature waste heat utilization.

TL;DR: In this paper, a multi-objective mathematical programming (MOMP) model is established to minimize the total construction investment and operation costs of each industrial park considering emission, energy balance and other technical constraints.
