Separation is a unit operation used in absorption heat pumps and chemical processing applications such as solvent extraction and product separations. A typical separation process in a heat pump application involves the desorption of ammonia from a water–ammonia solution. Although a number of configurations have been studied for this process at the macroscale, most are based on gravity and have relatively low rates of desorption. (more…)

Coalbed methane is produced within a process of oil and petroleum system. A petroleum system usually consists of oil in a sedimentary basin with a hydrocarbon source rock and all related oil and gas sources. Conventional petroleum system comprises of a hydrocarbon-generating source rock slate, with the help of heating and constant burial, resulted gas an oil. Coalbed methane is not same with coal which is originating from coal reservoir. The coal is a hydrocarbon source rock that developed during burial heating into a substance similar in structure to activated carbon. This is an organic substance that is chemically covered or heat-treated to increase micro-pores with a matching increase in the surface to increase gas sorption capacity. Coal produce methane gas and it has the capacity keep gas in place. (more…)

Coal is an important energy source and energy consumption in United States as well as worldwide. It will remain so for many years particularly in many developing countries. Fossil fuels stay as the main energy sources to the U.S. economy, but we can not ignore the importance of coal for decades. Coal production provides the price stability and will continue to be an significant source for electricity generation. Coal utilization is the major source of hydrogen in the coming hydrogen-based energy economy and it will be a crucial source of gas to liquid process of fuels energy.
Coal utilization and the importance of coal as source of energy industry perspective will change over time. (more…)

Water power sources is an interesting source of energy. It is available freely in nature. The constant flow of water can guarantee the availability of energy. Water power take it sources of energy from the motion of water. The motion of water is happening in river, sea and water fall. This movement can be derived from two resources:
1. Flows of water streams, this is attracted by earth gravity force
2. Tides which are the rise and fall of sea level by moon and sun gravity force (more…)

Within the coming years, fossil fuel will be failed back its main role as the ultimate main energy sources. Fossil fuels has known to have emit carbon energy and caused unrecoverable damages to environment in the long run. Low or zero carbon energy is gain popularity and nuclear power is known inline with this new movement in reducing the greenhouse effects. Nuclear power consisted of nuclear fusion and nuclear fission. Below we are explaining more detail about nuclear fission. (more…)
