Introduction of LNG station

The LNG has become the main gas source or transition gas source for cities which fail to use the pipeline gas currently, and also is the supplemental gas source or peak load gas source for many cities which use the pipeline gas. The LNG gasification station is a LNG ss station having receiving. storage and distribution functions, and also an intermediate regulation site for towns or gas enterpnses to transfer the LNG from manufacturers to users. 

The LNG gasification station has been gradually built in many economically developed and energy-deficient medium and small cities in China's South-East coastal areas depending on its advantages including short construction period and quickly meeting the gas market demands, becoming a permanent gas supply facility or a transition gas supply facility before arrival of the pipeline gas.
The LNG gasification station is generally assembled according to reasonable technology, integrating the LNG low temperature storage tank (cylinder or tanker) air-heated vaporizer, pressure reducing valves, chemical dosing system and metering system. It has features including compact structure, small volume and high automation degree.
Technological process of LNG station
LNG is transported to gasification stations by a tanker. Rise the pressure in the tanker by means of a LNG unloading pressurizer, and deliver the LNG in the tanker to the LNG low temperature storage tank When the LNG is discharged from the LNG storage tank, rise the pressure in the storage tank by means of the storage tank pressurization system,then open the liquid phase outlet valve of the storage tank,deliver the LNG in the storage tank to the vaporizer through pressure difference and then deliver it to the municipal gas pipeline network by working procedures such as pressure regulation, metering and odorization. When the outdoor ambient temperature is low and the natural gas temperature at the air heated vaporizer outlet is below 5 C, it is necessary to connect a water bath heater to the air-heated vaporizer outlet to heat the vaporized natural gas.
