The estimated costs for mining screen commercial plants are high so that a large mining screen power plant that has the working capacity of more than four hundred MW might be practical. This is especially true when the low cost mining screen financing can be obtained since some nations can tolerate higher power prices. Small power plants of the mining screen would be too expensive even if we take into account the subsidies of government to improve the oil drilling practices from many aspects. Therefore, mining screen would probably be required for any plant in why to maintain mud gun, and these may be by no means difficult to justify since low cost natural gas is available for power generation in mining screen. It has been reported that the unit mining screen can make use of electricity that is produced from oil shale powered plant and the figure would far exceed those generated from traditional mining screen thermal power stations. In other words, those mining screen that is supplied by heavy fuel oil or combined cycle plants can be used with imported natural gas. Moreover, when the mining screen environmental costs are taken into consideration natural gas represents the best option in most cases because there is no need for pollution abatement why to maintain mud gun technologies any more. Additional costs of mining screen will incur in other types of power plants due to the combustion of heavy fuel oil or oil shale.
The principal factors for mining screen usage could affect the commercialization of the vast oil shale resources in many countries. This is mainly because of the fact that mining screen in terms of readiness and costs of available extraction has been rather ideal in oil drilling processing technologies as well as the quality of the Decanter centrifuge markets for the products and byproducts. In the mining screen retorting area, some nations are presently engaged with five potential project developers under the memoranda of understanding that is initiated in early 2007. Four mining screen firms are considering above ground oil drilling processing, in which oil shale is mined with the help of mining screen and crushed and then heated in vessels. To be more specific, one mining screen firm is even considering heating the oil shale in place according to the mining screen study’s encouraging results. It is promising that mining screen producers could negotiate a production sharing agreement with the mining screen developer according to the implications of development for the social and physical environments. The mining screen can be adapted to meet the compatibility of laws and regulations including those related to health and environment in why to maintain mud gun.
