Abstract: In the process of production, processing, treatment, storage and transportation, petrochemical plants are prone to produce explosive gases and dust. Most areas of the plant are in the dangerous environment of explosion. Once the explosive gases and dust meet with lightning or sparks, they will cause explosion, resulting in equipment damage, ABSTRACTS PETROCHEMICAL SAFETY AND ENVIRONMENTAL PROTECTION TECHNOLOGY Bimonthly. 20 Oct. 2019 Vol. 35 No. 5 ·Ⅲ· production shutdown, and even casualties. Therefore, correct and reasonable lightning protection and grounding design play a vital role in the safe operation of the plant area. This paper starts with the basic concepts of lightning protection and grounding, and discusses the specific methods for lightning protection and grounding of the aromatics technical reform project of a petrochemical plant in the light of Code for Design Protection of Structures against Lightning (GB50027-2010) and Code for Design Protection of Petrochemical Plant against Lightning (GB50650-2011).
