液化氣產品

液化石油氣是在煉油廠內,由天然氣或者石油進行加壓降溫液化所得到的一種無色揮發性液體。它極易自燃,當其在空氣中的含量達到了一定的濃度范圍后,它遇到明火就能爆炸。
經由煉油廠所得到的液化石油氣主要組成成分為丙烷、丙烯、丁烷、丁烯中的一種或者兩種,而且其還摻雜著少量戊烷、戊烯和微量的硫化物雜質。如果要對液化石油氣進行進一步的純化,可以使用醇胺吸收塔將其中的氧硫化碳進行吸收脫除,最后再用堿洗去多余的硫化物。
經由天然氣所得到的液化氣基本不含有烯烴。液化石油氣主要是碳氫化合物所組成的,其主要成分為丙烷、丁烷以及其他的烷烴等。當然,液化石油氣的成分組成也是有標準的,并不是該成分組成的所有物質都可以稱為液化石油氣,只有氣體組成成分丙烷加丁烷百分之比超過百分之六十才可以被稱為液化石油氣。當然,并不是所有的標準都是一樣的,在國外,他們對于液化石油氣的規定就比較將就,它的定義需要根據季節的變化來對丙烷和丁烷的成分進行調整。但是我國目前的液化石油氣只要是對家庭進行使用,由此便沒有那么多的講究,如果是要將其運用到工業上來,我們就需要對液化石油氣的組成標準制定進一步更加細化的配比規則了  。
用液化石油氣作燃料,由于其熱值高、無煙塵、無炭渣,操作使用方便,已廣泛地進入人們的生活領域。此外,液化石油氣還用于切割金屬,用于農產品的烘烤和工業窯爐的焙燒等。
