Heat release from absorption storage heat pump by means of water vapor into aqueous sodium hydroxide is limited uptake kinetics affecting temperature gain, as well power- and energy density the method. Earlier studies pinpoint that natural diffusion alone not sufficient to reach higher rate, surface bulk exchange has be enforced. In this paper, different technical solutions problem for applicat...

This paper assesses the design guidelines of different classification codes for the liquefied natural gas carriers considering the effect of liquid sloshing. With regard the increasing importance of LNG carriers in today’s marine transportation, and also considering that the marine accidents involve significant loss, classification societies by regulating national and international standards ai...

compressibility factor and viscosity of natural gasses are of great importance in petroleum and chemical engineering. to calculate the natural gas properties in the pipelines, storage systems and reservoirs, the exact values of gas compressibility factor and viscosity are required. a new method that allows accurate determination of compressibility factor and gas viscosity for all types of: swee...

Natural gas hydrate (NGH) is widely considered as an alternative energy source due to its tremendous reserves, cleanness and high density. During the exploitation process, discharging gas-liquid phase surface for separation not only affects pump performance but also increases space requirements of offshore platform. Taking NGH production test data in South China Sea example, a downhole spiral s...

Hydrate formation/dissociation of natural gas in (diesel oil + water) emulsion systems containing 3 wt% anti-agglomerant were performed for five water cuts: 5, 10, 15, 20, and 25 vol%. The natural gas solubilities in the emulsion systems were also examined. The experimental results showed that the solubility of natural gas in emulsion systems increases almost linearly with the increase of press...

in this study, it was shown that how co2 and h2s were removed from a natural gas stream, using a nanofluid containing nanoporous graphene in diehanolamine (dea). before running the experiments, the appropriate values were chosen for the nanosheet dosage and the liquid and gas flow rates in the absorption experiments, which were performed in a laboratory scale wetted wall column. in the experime...

the objective of this research is to develop an accurate numerical method to be used in showing the deformation of a liquid fuel droplet in a convective field. to simultaneously solve the internal liquid droplet flow field as well as the external gas phase flow field, a nonstaggered rectangular grid system without any coordinate transformation is used. transition from the gas field to the liqui...
