Description
本發明係關於一種氣體液化裝置,尤其是一種可減少能源損耗之氣體液化裝置。The present invention relates to a gas liquefaction apparatus, and more particularly to a gas liquefaction apparatus capable of reducing energy loss.
一般而言,由於LNG[液化天然氣]或是一些工業用的特殊氣體[例如:NH3或CO2]等物質,在氣態時相當不穩定且佔體積,因此,為了提升安全性,唯有將其轉換為液態,方可安心的貯存及運送。In general, because LNG [liquefied natural gas] or some special gases for industrial use [such as NH 3 or CO 2 ] are quite unstable and occupy a volume in the gaseous state, in order to improve safety, only It is converted to a liquid state for safe storage and transportation.
舉例而言,請參照第1圖所示,揭示一種習知氣體液化裝置9,主要係由一壓縮器91、一冷卻器92及一渦輪機93依序利用管路互相連接所構成。該習知氣體液化裝置9於實際使用時,以二氧化碳[CO2]為例進行說明,係先將常溫常壓[溫度約為300 K,壓力約為1 atm]之氣態CO2(g)導入該壓縮器91內,以將其轉變為高溫高壓之氣態CO2(g)[溫度約為800 K,壓力約為20 atm];接著,該高溫高壓之氣態CO2(g)係流入該冷卻器92內定壓降溫後,再流經通過該渦輪機93膨脹降壓,即可獲得低溫低壓之液態CO2(l)加以貯存以供使用。For example, referring to Fig. 1, a conventional gas liquefaction device 9 is disclosed, which is mainly composed of a compressor 91, a cooler 92 and a turbine 93 which are connected to each other by a pipeline. The gas liquefaction device 9 of the prior art is described by taking carbon dioxide [CO 2 ] as an example, and first introduces a gaseous CO 2 (g) at normal temperature and normal pressure [temperature of about 300 K, pressure of about 1 atm].
