- 制造環(huán)氧乙烷
Ethylene oxide has been produced commercially by two basic routes: 環(huán)氧乙烷已經(jīng)商業(yè)化生產(chǎn),由兩個(gè)基本路線 :
1. 1。
From ethylene chlorohydrin. 從乙烯氯。
2. 2。
Direct oxidation process. 直接氧化過(guò)程。
The chlorohydrin process was first introduced during World War I in 氯過(guò)程在第一次世界大戰(zhàn)期間首次推出
Germany by Badische Anilin-und Soda-Fabrik (BASF). 德國(guó)巴登苯胺和蘇打Fabrik公司(BASF)。 The process 這個(gè)過(guò)程
involves the reaction of ethylene with hypochlorous acid followed by 其次涉及次氯酸與乙烯反應(yīng)
dehydrochlorination of the chlorohydrin with lime to produce ethylene oxide 與石灰氯,氯化氫,生產(chǎn)環(huán)氧乙烷
and calcium chloride. 氯化鈣。 Union Carbide Corp. was the first to commercialize 聯(lián)合碳化物公司是第一個(gè)以商業(yè)化
this process in United States. 這在美國(guó)的過(guò)程。 The chlorohydrin process is not economically 氯的過(guò)程是不經(jīng)濟(jì)
competitive, and was quickly replaced by the direct oxidation process as the 競(jìng)爭(zhēng)力,并很快被取代了直接氧化過(guò)程
dominant technology. 主導(dǎo)技術(shù)。 At present time, all the ethylene oxide production in 目前,所有的環(huán)氧乙烷生產(chǎn)
the world is achieved by the direct oxidation process. 世界是通過(guò)直接氧化過(guò)程。
The direct oxidation technology, as the name implies, utilizes the 直接氧化技術(shù),顧名思義,利用
catalytic oxidation of ethylene with oxygen over a silver based catalyst to 超過(guò)銀基催化劑催化氧化,與氧乙烯
yield ethylene oxide. 產(chǎn)量環(huán)氧乙烷。 The process can be divided into two categories 該工藝可分為兩大類(lèi)
depending on the source of the oxidizing agent. 取決于氧化劑的來(lái)源 。 The air-based process and 空基的過(guò)程和
the oxygen based process. 基于氧氣的過(guò)程 。 In the first , air or air enriched with oxygen is fed 在第一階段,豐富的空氣或空氣與氧氣送入
directly to the system. 直接系統(tǒng)。 In the second high purity oxygen stream (>98 mol%) 在第二個(gè)高純度的氧氣流(> 98 mol%的)
from an air separation unit is employed as the source of the oxidizing agent. 受聘為氧化劑的來(lái)源是從空氣分離裝置 。 ...
