Natural gas can be extracted from the use of it?
3 LNG plant can be divided into basic load type, peak type two. Liquefaction process to APCI (American air liquefaction company) process based. (propane precooling mixed refrigerant liquefaction process)4 China's natural gas accounted for only 2.6% of total energy consumption, by 2010, this ratio is expected to reach 7% - 8%5 China's LNG plant: the end of 1990s, the East China Sea early development and utilization of natural gas in Shanghai to build a daily processing of natural gas accident peak of 100 thousand cubic meters. In 2001, the Zhongyuan Petroleum Exploration Bureau to build the first production of liquefied natural gas units, daily processing capacity of 150 thousand cubic meters. 2002 Xinjiang Guanghui group began to build a processing capacity of 1 million 500 thousand cubic meters of LNG plant, storage tank design capacity of 30 thousand cubic meters. .
0 cooling dehydration is the use of pressure when the same, the natural gas water content decreases with the reduction of temperature to achieve the principle of natural gas dehydration, this method is only applicable to a large number of coarse water separation.11 adsorption dehydration: a method of absorbing liquid (or solid). Three glycol dehydration, suitable for large natural gas liquefaction plant in the raw material gas containing most of the water.12 adsorption dehydration: the main applicable adsorbents are: activated alumina, silica gel, molecular sieve, etc.. Most of the adsorption dehydration methods used in modern LNG plant are molecular sieve adsorption. In practical use, molecular sieve can be used in series with silica gel or activated alumina.
6 LNG terminal: Shenzhen Dapeng Bay, Fujian Meizhou Bay, Zhejiang, Shanghai and other places.7 natural gas pretreatment: removal of natural gas, such as hydrogen sulfide, carbon dioxide, water, heavy hydrocarbons and mercury and other impurities, so as not to impurities in the corrosion of equipment and low temperature freezing and blocking equipment and pipelines. , _&K=!8: if the dehydration of natural gas contains water, in the liquefaction plant, the water below zero in the form of ice or frost on the surface of frozen section, and a throttle valve of the heat exchanger in natural gas and water gas hydrate formation, it is a solid compound semi stable, can formed in the above zero, it may not only lead to pipeline obstruction, can also cause clogging the nozzle closing separation equipment.9 commonly used dehydration methods are: cooling, absorption, adsorption, etc..
want1 use of natural gas:Chemical fuel, residential fuel, automotive fuel, combined power generation, heat pump, fuel cell, etc.. NqP2 liquefied natural gas::The main component of natural gas is methane, the critical temperature is 190.58K, temperature LNG storage 112K (-161 C), low temperature tank pressure is about 0.1MPa, the density of methane under the condition of the standard of 600 times, the volume energy density of gasoline is 72%.
