安全知識－Gaseous Argon氬氣

Gaseous argon is tasteless, colorless, odorless, non corrosive, and nonflammable. Argon belongs to the family of rare inert gases. It is the most plentiful of the rare gases making up approximately 1% of the earth’s atmosphere. It is monatomic and extremely inert, forming no known chemical compounds. 氣態(tài)氬無味，無色，無嗅，無腐蝕性，不可燃。氬屬于稀有惰性氣體家族。它是最豐富的稀有氣體，占地球空氣的約1%。它是單原子，極不活潑，沒有已知的化合物。 Special materials of construction are not required to prevent corrosion. Vessels and piping should be designed to American Society of Mechanical Engineers (ASME) or Department of Transportation (DOT) codes for the pressures and temperatures involved. 不要求特殊的建材來防止腐蝕。容器和管道系統(tǒng)要根據相關的壓力和溫度按照美國機械工程師協(xié)會（ASME）或交通部（DOT）的規(guī)定來設計。 Argon may be compressed into cylinders by water or oil-lubricated compressors or by dry compression systems. To determine the amount of argon in a cylinder, use the appropriate pressure and temperature capacity chart for a specific size cylinder. (The higher the pressure, the larger the amount of argon in the container.) 氬可以使用水或油潤滑的壓縮機或干壓縮系統(tǒng)壓縮進鋼瓶。要確定鋼瓶的氬容量，對于特定尺寸的鋼瓶使用合適的壓力和溫度容量表。（壓力越大，容器的氬容量越大） Manufacture生產 Argon is produced by an air separation unit(ASU) through the liquefaction of atmospheric air and separation of the argon by continuous cryogenic distillation. The argon is then removed as a cryogenic liquid. 氬的生產使用空氣分離裝置（ASU），通過大氣的液化和連續(xù)低溫蒸餾分離出氬。隨后，氬作為低溫液體運輸。 The ASU manufacturing process begins with a main air compressor and ends at the output of the product storage tanks. Air is compressed and sent through a clean-up system where moisture, carbon dioxide, and hydrocarbons are removed. The air then passes through heat exchangers where it is cooled to cryogenic temperature. The air then enters a high pressure distillation column where it is physically separated into a gaseous form of nitrogen at the top of the column and a liquid form of “crude” oxygen (~90%) at the bottom. ASU生產過程從一個主氣流壓縮機開始，產品儲存罐的輸出后結束?？諝馔ㄟ^一個去除了水蒸汽、二氧化碳和碳氫化合物的清潔系統(tǒng)壓縮和輸運。接著空氣通過熱交換器冷卻到低溫。隨后空氣進入高壓分裂蒸餾塔，分離成氣態(tài)氮和“原始”液氧（含大約90%的氧），氮蒸氣在蒸餾塔頂部，液氧在蒸餾塔底部。 Argon is the major contaminant in this crude oxygen, which is then sent to a low-pressure distillation column where the oxygen is purified. The argon-rich waste stream from the low pressure column is sent to an argon distillation column. Some argon technologies distill the argon directly to its final manufacturing purity, while others utilize a separate step to purify it, for example, hydrogen deoxo. Purified argon is stored as a liquid in storage tanks at the site. 氬是原始氧中最大的雜質。接著把原始液氧送到低壓分裂蒸餾塔凈化。從低壓塔流出的富氬廢物被送到氬分裂蒸餾塔。某些氬技術直接把氬蒸餾到最終的生產純度，而其它技術采用分離的步驟來凈化它，例如氫脫氧。凈化的氬以液態(tài)形式儲存在現(xiàn)場的儲存罐。
