The presence of sand close to hydrocarbons in production is most often harmful well productivity. This also leads undesired problems surface devices and equipment, as obstructions the column and, consequently, decreasing fluid flow causing severe economic losses field. objective this work study influence content pipelines through simulation using computational dynamics tools ICEM CFD ANSYS CFX ...

One of the costliest problems facing production hydrocarbons in unconsolidated sandstone reservoirs is sand once hydrocarbon starts. The sanding start prediction model very important to decide on control future, including whether or when should be used. This research developed an easy-to-use Computer program determine beginning sites driven area. based estimating critical pressure drop that occ...

The costs related to comminution in the mineral industry are significant, thus representing main challenge for optimizing such a process. During last few decades, technology of High-Pressure Grinding Rolls (HPGR) has been consolidated as an important alternative circuits, due relatively low operational cost, well high energy efficiency. Due initial capital costs, HPGR applications limited high-...

BACKGROUND The aim of this study was to compare between slow and rapid sand filters for the removal of free-living amoebae during drinking water treatment production. METHODS Overall, 48 water samples were collected from two drinking water treatment plants having two different filtration systems (slow and rapid sand filters) and from inlet and outlet of each plant. Water samples were collecte...
