CN108261888A 一种液化气脱硫醇碱液再生尾气除臭方法 无效 - 驳回

一种液化气脱硫醇碱液再生尾气除臭方法
摘要：
本发明属于属于化工尾气处理技术领域，具体涉及一种液化气脱硫醇碱液再生尾气除臭方法。该方法包括对液化气脱硫醇碱液再生尾气进行水洗处理，洗掉再生尾气中残留的碱液；将经过水洗的再生尾气进行柴油洗处理，经过柴油吸收后去除再生尾气中的硫化物；将经过柴油洗的再生尾气进行吸附除臭处理，进一步去除再生尾气中的硫化物。本发明在对碱液再生尾气进行吸附除臭前，对尾气依次进行了水洗和柴油洗处理，能够延长吸附除臭装置的使用寿命，降低操作成本，同时满足各项环保指标的要求。
摘要（英）：

The invention belongs to the technical field of chemical industry tail gas treatment, and concretely relates to a liquefied gas desulphurization alcoholic lye regeneration tail gas deodorizing method.The method comprises the following steps: washing liquefied gas desulphurization alcoholic lye regeneration tail gas with water to remove an alkali lye residual in the regeneration tail gas; washingthe water-washed regeneration tail gas with diesel oil to absorb sulfides in the regeneration tail gas; and performing adsorption deodorizing treatment on the diesel-washed regeneration tail gas to further remove sulfides in the regeneration tail gas. The tail gas is sequentially washed with water and diesel before undergoing adsorption deodorizing, so the service life of an adsorption deodorizingdevice is prolonged, the operating cost is reduced, and requirements of all environmental protection indexes are met.
