Solving Erosion and Corrosion Problems in Jordanian-Potash Company

The amount of surface material eroded by solid particles in a fluid stream depends on the conditions of fluid flow and on the mechanism of material removal. The paper  first analyses the mechanism of material removal for ductile and brittle materials. For ductile material, it is noted that erosion produced by particles striking the surface at shallow angles (  but the maximum erosion in brittle materials at perpendicular impact at ( . In  this paper ductile materials (steel alloys) are studied, then the paper discussed some aspects of the fluid flow conditions which may lead to erosion. Kind of pipe which connect between pumps and factory in Potash Company-Jordan is a carbon steel pipe. Because of large pressure from pumps (10 bar) and huge mass flow rate (about 700(m3 /hr)), particles (KCl, NaCl, ,MgCl) will strike with inner of pipe, erosion will happen, so a pipe will destroyed after many years. This problem considered costly, where Arab Potash Company is changing this pipe every seven years. Keywords: Erosion, Corrosion, Pipe System, Cracks, Fluid Flow, Steel Alloys, Brittle, Ductile

Emissions Reduction Resulting from Renewable Energy Projects in Jordan

This paper aims to present energy supply, demand and policy reforms, in Jordan, that had helped in transforming renewable energy schemes into bankable projects. The current study focuses on implemented and planned renewable projects and its investment as a case study aiming to identify impacts on economy and environment, with emphasis on the power sector. In order to attract private sector participation in the development of such projects, the government developed and enacted a new system of direct proposals as well as needed regulations. This resulted in the construction of more than 1000 MWe of renewable energy and awarding about 1500 MWe to be completed until end of 2024. According to the adopted methodology, in this study, the calculated avoided GHG emissions resulting from the completion of these projects, during the study period from 2016 and up to 2025, are significant. The net anticipated accumulated reduction of GHG emission over this period exceeded 16 million ton of CO2 eq. The solar PV sharing ratio being the highest, i.e. 45% of total accumulated reduction, followed by wind, about 24%, and direct applications of renewables by 28%. Such figure may increase in the future depending on the completed capacity and would touch 20 million ton by 2025, when all planned projects are completed.
