摘要: 在乙烯装置中,干火炬与湿火炬汇气合之前需要先进行过热。介绍了自然升温、夹套加热和过热器过热等几种目前常用的过热方法,阐述了它们的设计原理及技术、操作特点,并就其在防冻堵和减少低温材质用量方面的优劣势做了分析和对比,认为过热器直接过热法安全可靠性高,最节省投资。

Abstract:

In ethylene plant, dry flare gas needs to be superheated before it joins with wet flare gas. Several commonly used superheating methods are introduced in this paper, including natural heating, jacket heating and superheating via superheater. The design principles, technical characteristics and operation characteristics of these methods are discussed, and their advantages and disadvantages in preventing freeze blockage and reducing the consumption of low temperature materials are compared and analyzed. It is concluded that direct superheating via superheater has high safety and reliability and the lowest investment.

Key words: dry flare gas, natural heating, jacket heating, superheating via superheater
