Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard was proposed by the China Petroleum and Chemical Industry Federation. This standard is under the jurisdiction of the National Chemical Standardization Technical Committee (SAC/TC63). This standard was drafted. Beijing Sanju Environmental Protection New Materials Co., Ltd., Tongling Tongguan Shenhong Chemical Co., Ltd., Sinopec South Beijing Chemical Research Institute Co., Ltd., Xi'an Xiangyang Aerospace Materials Co., Ltd. The main drafters of this standard. Sun Guoshuang, Ni Xuemei, Liu Yujun, Xu Shuyan, Chi Ying, Tang Yan, Zhao Suyun, Dai Zhengliang, Feng Chao, Li Pingli. Alkaline earth metal high temperature dechlorination agent chlorine capacity test method Caution - some of the reagents used in this method are corrosive and must be handled with care. If splashed on the skin, immediately flush with water. Wash, severe cases should be treated immediately. In addition, the raw material gas and tail gas (including HCl and Cl2) are poisonous to human health and safety. The system should be strictly prevented from leaking, and the site should be equipped with precautionary measures such as exhaust ventilation equipment.

1 Scope

This standard specifies the chlorine volume test method for alkaline earth metal high temperature dechlorination agent. This standard is applicable to alkaline earth metal dechlorination agents for removing hydrogen chloride from petrochemical gas and liquid materials under high temperature conditions.

2 Normative references

3 Principle

3.1 Under high temperature conditions, the hydrogen chloride gas in the feed gas reacts with the dechlorination agent to form a stable metal chloride. Chemical reaction The equation is as follows. MxOy 2yHCl=MxCl2y yH2O 3.2 Calculate the penetrating chlorine capacity by measuring the mass fraction of chlorine in the dechlorination agent after the reaction.

4 General regulations

The reagents and water used in this standard refer to the analytical reagents and the tertiary water specified in GB/T 6682 when no other requirements are indicated. test The standard titration solutions, preparations and products used in the products are in accordance with the provisions of GB/T 601 and GB/T 603 when no other requirements are specified. preparation.
