For this study, PEC Consulting surveyed top lime producers in the United States that had used the selected vendor for refractory supply. Our client in Peru also asked PEC Consulting to further analyze the conversion of vertical clinker kilns to manufacture lime. A complete study was prepared and delivered including options and recommendations.

GEOLOGICAL STUDIES – The expertise of our Geological Consultants is being utilized by one of our clients in Colombia for the research and development of cementitious products to use as raw materials for clinker production. At the same time, our Geologist is assisting with the certification of clay pit resources for their quality and reserves.

RAIL TO TRUCK TERMINAL – PEC Consulting evaluated options for the construction of a terminal using new equipment or relocating equipment from an existing terminal to the designated site. Based on site visits and economic analysis, some of the equipment from the old site was found adequate for relocation. A preliminary project schedule, CapEx, flow sheets and equipment lists were prepared and included with the report to the client.
