["2. 我们公司的MTBE装置需要加脱硫剂，有几次副操吧脱硫剂关了之后硫含量也没啥变化。我想问问，脱硫剂该不该加，然后我们公司是一次加一小桶，很费劲。要不要一次性加好多，让他慢慢下呢？"

[" 你们装置是侧线抽出+提塔的工艺流程直接塔底MTBE进脱硫塔的工艺？"

[" 第一次技改侧线抽出，对降低MTBE中硫含量不明显。技改失败！然后拆了，重新建一个脱硫塔，将塔底MTBE直接进脱硫塔分馏（有时候进料中掺少量的汽油，提高脱硫塔塔底温度）。塔顶出低硫MTB，塔底高硫重组分间断外排。起初也打算加什么脱硫剂的，后来直接省略，只是加点汽油。。。。。。"

[" 先实验室做小试，确认脱硫是否有效果。无效果再分析MTT中硫组成，重新选择脱硫剂。"
