摘要
在TEA配合铁法脱硫、EDTA配合铁法脱硫和新开发的脱硫剂脱硫实验过程中,依次增加硫酸根离子浓度,进行硫化氢脱除实验,发现电位依次降低,浊度变小,即析硫速度变小。在湿式氧化法脱硫剂脱硫过程中,随着副反应发生,硫酸根离子积累,影响了催化剂再生。
The falling turbidness and electric potential lead to the low removal rate of hydrogen sulfide in the course of applications such as TEA process, EDTA process and new - exploited process by adding the sulfate radical ion to the solution step by step. This course also showed that the catalysts got the rebirth slowly, and the side reaction in desulfurization caused the accumulation of the sulfate radical ion.
