Simulation Results

The aim of this article is to evaluate the viability of transporting Liquified Natural Gas (LNG) by truck in the Mato Grosso (MT) state, Brazil, comparing the costs of substituting other energy sources for the Bolivian Natural Gas (NG) and estimating the potential available market in the five mesoregions of the state. The simulation results show a potential NG market of 2.1 MMm3/day at a competitive cost compared to the assessed fuels in the economic sectors evaluated in the MT state. LNG transported by road has shown to be more advantageous than electric energy and diesel oil. On the other hand, fuel oil costs were slightly lower than NG costs. This simulation can serve as inspiration to extend the use of small-scale LNG by road in states or countries with similar characteristics, especially those with the possibility of the constant supply of NG and limited pipeline network.

Subject Pakistan's LNG imports and natural gas supply. Significance Pakistan in July claimed it could become one of the top five purchasers of liquefied natural gas (LNG) by 2022. The country is looking to address growing gas demand and reduce capital outflows for fuel oil and diesel imports; regasification facilities are required to convert LNG back to natural gas at atmospheric pressure. Impacts Fewer power shortages would decrease protests, especially prevalent in summer months, over blackouts. Pakistan’s natural gas vehicle sector could see a rejuvenation, curbing gasoline and diesel demand. Increased LNG use in domestic fertiliser production will reduce urea imports.

In the course of the worldwide efforts to suppress the global warming, the saving energy becomes more important. Recently, the LNG (liquefied natural gas) terminals in our country have received more than 50 million tons of LNG per year. Therefore, the utilization of the cryogenic exergy in connection with the regasification of LNG gains more and more importance. The aim of this paper is the recovery of the energy consumed in liquefaction using the MGT (Mirror Gas Turbine), which is a kind of new combined cycle of a conventional gas turbine worked as a topping cycle and TG (inverted Brayton cycle) as a bottoming cycle. The optimum characteristics have been calculated and it is shown that this cycle is superior to the current-use gasification systems in employing seawater heats in terms of thermal efficiency and specific output. In the present cycle, the cold of LNG is used to cool the exhaust gas from a turbine of TG, and then the exergy of the liquefied natural gas is transformed to electric energy with a very high efficiency. The main feature of this new concept is the removal of an evaporation system using seawater.

Rose Oil

The evaluation is related to two installations for water-steam distillation in a capacity of around 10 t rose flowers in case of 24-hour operation. It was specified that the specific consumptions per 1 kg processed rose flowers are as follow: 4 kg/kg for steam, 8 MJ/kg for heat energy, 0.26 kg/kg for natural gas (PNG, CNG), 0.28 kg/kg for LPG, 0.31 kg/k g for fuel oil, 0.90 kg/kg for wood pellets, 1.54 kg/kg for wood chips, 107 kJ/kg for electric energy, 10 L/kg for cooling water and 4.2 L/kg for tap water. The specific consumptions per 1 kg produced rose oil are about 14 t/kg for steam, 29 GJ/kg for heat energy, 914 kg/kg for natural gas, 982 kg/kg for LPG, 1080 kg/kg for fuel oil, 3196 kg/kg for wood pellets, 16301 kg/kg for wood chips. The costed shares related to the price of 1 kg rose oil are as follow: 21.4 % in case of using fuel oil, 13.9 % for LPG, 9.9 % for PNG, 9.7 % for CNG, 7 % for wood pellets, 4 % for wood chips; 0.32 % for tap water, 0.17 % for electrical energy.
