LNG已成為目前無(wú)法使用管輸天然氣供氣城市的主要氣源或過(guò)渡氣源.也是許多使用管輸天然氣供氣城市的補充氣源或調峰氣源。LNG氣 化站是一個(gè)接收、儲存和分配 LNG衛星站.也是城鎮或燃氣企業(yè)把LNG從生產(chǎn)廠(chǎng)家轉往用戶(hù)的中間調節場(chǎng)所。 LNG氣化站憑借其建設周 期短以及能迅速滿(mǎn)足用氣市場(chǎng)需求的優(yōu)勢.己逐漸在我國東南沿海眾多經(jīng)濟發(fā)達、能源緊缺的中小城市建成，成為供氣設施或管輸天 然氣到達前的過(guò)渡供氣設施。
LNG氣化站是將LNG低溫儲罐（鋼瓶、槽車(chē)）、空溫式氣化器；減壓閥組、加藥裝置、計置系統于一體，按照合理的工藝流程總裝集成。 結構緊湊，體積小，自動(dòng)化程度高。
Introduction:
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 satellite station having receiving, storage and distribution functions, and also an intermediate regulation site for towns or gas enterprises 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’s 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.
工藝流程：
LNG由槽車(chē)運至氣化站，利用LNG卸車(chē)增壓器使槽車(chē)內壓力增高，將槽車(chē)內LNG送至LNG低溫儲罐內儲存。當從LNG儲罐外排時(shí)，先通過(guò)儲罐的自增壓系統，使儲罐壓力升高.然后打開(kāi)儲罐液相出口閥，通過(guò)壓力差將儲罐內的LNG送至氣化器后，經(jīng)調壓、計量、加臭等工序送入市政燃氣管網(wǎng)。當室外環(huán)境溫度較低，空溫式氣化器出口的天然氣溫度低于5℃時(shí)，需在空溫式氣化器出口串聯(lián)水浴式加熱器，對氣化后的天然氣進(jìn)行加熱。
Technological process:
The 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℃, it is necessary to connect a water bath heater to the air-heated vaporizer outlet to heat the vaporized natural gas.
