The tube bundle of the crude oil reduction fifth-line heat exchanger in the atmospheric and vacuum distillation units of the petrochemical industry is severely clogged on the tube side
Thread Content
The image below shows the tube bundle of the crude oil vacuum distillation unit in the petrochemical industry. Model: BES700-40-100-6/25-6, Material: 10#, Operating conditions: Shell side: crude bottom oil, temperature 303°C, pressure 1.65 MPa. Gangcheng: Medium, minus five lines, temperature 363°C, pressure 0.91 MPa. This heat exchanger has been in use for over two years; during maintenance, it was found that the tubes in the tube side of the heat exchanger were severely clogged.
Blockage in the tube side of a heat exchanger can be caused by various factors, including deposits, dirt, corrosion, and solid particles in crude oil. For this situation, the following measures can be considered: 1. Cleaning: Periodically perform chemical or mechanical cleaning of the heat exchanger to remove deposits inside the tubes. 2. Material selection: Consider using materials with greater corrosion resistance to reduce the risk of blockages caused by corrosion. 3. Monitoring: Strengthen the monitoring of operational data to detect abnormal changes in temperature and pressure promptly, and predict blockage issues in advance. 4. Optimize the process: Improve the crude oil treatment process to reduce the entry of impurities into the heat exchanger. Regular maintenance and inspection are important measures to avoid blockages. .
