The production of raw materials for energy generation – coal, oil, and gas offers considerable scope for the use of decanter centrifuges, at least for coal and oil. The manufacture of gas is a little-used process now that natural gas is so freely available. When this phase passes, as gas availability reduces, then the gasification of coals and heavy oils will also offer good applications (as will the eventual need to convert coals into liquid fuels).Continue reading “Decanter Centrifuge And Energy Materials Production”
Water dilution and subsequent disposal of the excessive mud volume into drilling reserve pits were the simplest ways of dealing with inefficient solids control systems.Properties of all drilling muds tested are shown in Table 1. The only drilling mud used for the full-scale test was the non-dispersed spud mud with limited filtration control.Continue reading “Dewatering Process Efficiency and Effects”
A one-step, unique solids control system can simultaneously discard small and large particles from the mud. The one-step solids control fluid conditioning can deliver desirable rheological properties and a reasonable size range for the suspended material.
A simple and economical surface solids control method to complement the downhole systems becomes necessary when we desire to reduce viscosity, yield point, gel strength, total solids, concentration of drilled solids, and low micron-size material. This aim will be achieved when we are able to partially reject the undesirable materials from the drilling fluid system.
