Liquid Natural Gas

Liquefied natural gas (LNG) is known as a clean energy source which is widely used in electricity generation and daily living for its friendly environment performance. The global LNG trade has increased rapidly during recent years. Liquid natural gas delivered by sea-ships contains considerable cryogenic exergy which can be utilized for electricity production before its evaporation and introduction into the system of pipelines. Because the need to vaporize LNG offers a thermal sink at a very much lower temperature than seawater, using this thermal sink both power and gas can be produced. So it is possible to recover power from the vaporization of LNG. Based on the exergy analysis of normal Rankine power cycle and LNG gasification characteristics at a different pressure, this paper proposed a cascading power cycle with LNG cold energy recovery, in which a three-tier Rankine cycle system was established to recovery the liquid heat and latent heat of LNG, and the residual sensible heat of LNG vapor can be used to prepare the cold water of central air-conditioning in plant area. The simulating results showed that the cascade power system can improve the LNG cold energy recovery efficiency.

Recovery Techniques

For many decades all major conservation bodies have realized the need to conserve our valuable fuel and power sources. The increased level of consumption of fuel and power results in carbon-di-oxide emissions to environment which results in the depletion of ozone layer leading to global warming. As a result, many ways of utilizing renewable fuel and power sources are developing with solar energy and waste heat recovery applications. Most of the process and industries have large capacity Diesel Generating (DG) set. The exhaust gas of such a DG set carries a lot of heat and it goes waste if it is not utilized properly. Energy recovery from engine exhaust is one of the energy saving methods in engines. By using energy recovery techniques, waste heat energy can be saved, emissions can be reduced and thermal efficiency of the engine is increased. This paper discusses about the exhaust gas energy recovery from engine exhaust using Rankine cycle and thermodynamic properties of the working fluids. The heat energy recovered from the engine exhaust can be utilized for various sources.
