煤层气脱硫氧化再生槽的设计

Design of Oxidation Regenerator for Coal- bed Methane Desulfurization

煤层气在利用之前,需要通过脱硫系统将其中的H2S脱除至要求浓度以下。介绍了煤层气脱硫氧化再生技术,阐述了目前常用的PDS法湿式脱硫氧化再生技术的原理和工艺过程;讨论了再生时间、温度、脱硫液碱度等因素对氧化再生工艺的影响,基于这些条件,对氧化再生槽的结构、喷射器进行了设计。

Before the use of the coal-bed methane, H2S content in it must be lowered down to the demand with the desulfurizing system. This paper described the oxidation regeneration method for coal- bed methane desulfurization, and expounded the principle and technological process of the presently-used PDS wet oxidation regeneration method for coal-bed methane desulfurization, discussed the influence of some factors such as the regenerating time, temperature and the alkalinity of desulfurizing solution on the oxidation regeneration method, and based on these conditions, the structure of the oxidation regenerator and the injector were designed.
