A mathematical model considering mass and momentum transfer was developed for simulation of ethanol dewatering via pervaporation process. The process involves removal of water from a water/ethanol liquid mixture using a dense polymeric membrane. The model domain was divided into two compartments including feed and membrane. For a description of water transport in ...

in all over the world, mining is considered as a high-risk activity that is pregnant with serious disasters not only for miners, engineers, and other people into it, but also for people who live near the mines. in this article, our main purpose is to examine some major mine disasters and safety in mines and the case study is a coal mine in turkey. safety in mines is one of the most important is...

Abstract A key challenge in many regulated rivers is to define adequate flow levels protect aquatic organisms. Provisioning of suitable can be pivotal bottlenecks for fishes such as salmon and trout that use the riverbed an incubation habitat. Additionally, locations where females spawn will probability embryos dewatered during period a regime. We investigated water flow, dewatering, mortality ...

In the context of open-pit mine planning, uncertainties including commodity price would significantly affect the technical and financial aspects of mining projects. A mine planning that takes place regardless of the uncertainty in price just develops an optimized plan at the starting time of the mining operation. Given the price change over the life of mine, which is quite certain, optimality o...
