In the post independence India, the recent land and community conflicts are emerging as great challenges ahead
of technology and project finance. Land and community related conflicts are on the rise in populous and land short
emerging economies of India where rehabilitation and resettlement schemes by the government and the corporate
in the mining areas are bringing in mixed results.
Poor knowledge of mining and mineral engineers about the aspects of land holdings, politics and little knowledge
of local culture of the settled and tribal communities are bringing in industrial hurdles and great economic loss.
The paper describes the issues and case studies of similar events in India and the preparedness of the corporate to
handle the crisis.

Energy management in the phosphate industry is very important; especially in the sulfuric acid plant, as it is the
main source of energy for the production of both intermediate and final products. In this context, and for the
sake of rational and efficient usage of available energy sources, it has been decided to assess the impact of «Pinch
Analysis» and «Process Integration» on a DAP production process, and deduce some useful conclusions with
regard to its application to this kind of industry.
Process integration includes a number of techniques that allow engineers to evaluate entire processes or
sites, rather than focusing on individual unit operations. This includes hierarchical design methods, knowledgebased
systems, numerical and graphical techniques and pinch analysis. However, in the area of energy efficiency,
which is the primary focus of this work, pinch methods are dominant, but are often interchangeable with “process
integration (PI)” in this field.
The first phase of this analysis employed pinch targeting within an existing fertilizers plant, a methodology for
identifying energy-cost reduction potential based on the thermodynamic characteristics of a process. The second
phase consists of identifying potential solutions corresponding to opportunities identified during the assessment.
This assessment involved mainly the production area of the plant related to sulfuric acid production. Several
opportunities for energy use reduction were identified, and related annual savings resulting from any eventual
energy conservation project have been evaluated.
