Corrosion of the outlet pipeline of the catalytic compressor

Corrosion in the outlet pipeline of the compressor in the catalytic unit mainly occurs in the following areas: 1. Pipelines near the feed condenser: Acidic substances and moisture are present in the feed condenser, and these can cause corrosion on the inner surface of the pipelines. 2. High-temperature area near the compressor outlet pipeline: Under high-temperature conditions, the pipeline material is prone to thermal stress and oxidative corrosion. 3. Pipelines in the post-treatment section of the catalytic unit: Corrosive solutions or gases are often used in the post-treatment section, and these substances can cause corrosion to the pipelines. The main reasons for corrosion in the outlet pipeline of the compressor in catalytic units include: 1. Chemical reactions: Gases and liquids within the pipeline can generate corrosive substances through various chemical reactions, such as acidic substances and oxides, which can cause corrosion on the pipeline surface. 2. Temperature and pressure: Under high temperatures and pressures, pipeline materials are prone to oxidation reactions and thermal stress, leading to corrosion on the pipe surface. 3. Environmental factors: The environmental conditions in which the pipes are located can also affect corrosion; for example, humidity and gases or solutions with high salt content can accelerate pipe corrosion. To address these corrosion issues, various preventive measures can be taken, such as using corrosion-resistant materials, applying protective coatings, and regularly cleaning and maintaining the pipes. Furthermore, the proper selection of process conditions and effective monitoring and control are also important measures to prevent pipeline corrosion. .
