The TSHI (Total Site Heat Integration) methodology is extended in this paper to manipulate the Total Site Profiles (TSP) towards further decreasing the heat transfer area (HTA), and consequently the capital cost, of heat transfer units. In the first case study, the application of Keep Hot Stream Hot (KHSH) and Keep Cold Stream Cold (KCSC) on TSP reduces the heating and cooling duties resulting in a reduction of 8 % in heat transfer area (HTA) and a saving of 8 % in heat exchangers cost. In the second case study, when KHSH/KCSC principles is applied on the selected segment of the TSP while maintaining the enthalpy constant, the TSP shape is changed to provide a larger temperature driving force, this together with the reduced heating and cooling loads, reduce the HTA by 11 % and the heat exchangers cost by 12%. process modifications to achieve the desired shape of TSP may be limited by technical feasibilities or economic reasons. However, the potential for the feasible/profitable modifications of the TSP shapes is worth to be analysed and studied as they can be enhanced by exploring the potentials to integrate neighbouring units such as services, businesses residential and even agricultural units, i.e. the locally integrated energy sector (LIES), a concept introduced by Perry et al (2008).

A large volume of fish wastes is produced on a daily basis in the Indian sub-continent. This abundant waste source could serve as an economic feedstock for bioenergy generation. In the present study, oil extracted from discarded fish parts was used for high quality biodiesel production. More specifically, a single step transesterification of 'waste fish oil' with methanol using sodium methoxide (CH3ONa) as homogeneous catalyst under moderate operational conditions resulted in highly pure biodiesel of > 98% of fatty acid methyl ester (FAME) content. Characterization was performed by Fourier Transform-Nuclear Magnetic Resonance (FT-NMR). © 2014 BRTeam.

In an effort to diversify economies and reduce high oil dependency, the Gulf Cooperation Council (GCC) countries plan to increase the use of renewable energy sources to meet the challenges of a post-oil future. The Accession to the United Nations Framework Convention on Climate Change (UNFCCC) and the Kyoto Protocol, which require a commitment to reduce greenhouse gas emissions, has started a process of environmental awakening in the GCC countries. This paper reviews the publications on renewable energy with reference to the GCC countries since 2005. The objective was to investigate the benefits of funding and investing in renewable energy projects in the GCC countries. The article shows that the GCC countries have begun to adopt a more pro-active approach toward renewable energy that will help progress the GCC countries towards sustainability. The reorientation of strategies and policies toward renewable energy is evolving in the GCC countries. © 2014 Elsevier Ltd. All rights reserved.
