Question: (DMTO) Olefin Separation Unit: What is the purpose of acid washing the compressor oil circuit? The purpose of acid cleaning the oil circuits is to remove rust and oxide deposits accumulated on the pipes, as well as other foreign substances attached to them, thereby reducing the time required for oil flushing. Note: The answers will be announced automatically in two days!
To remove rust spots and oxide layers deposited on the pipes, as well as other foreign substances attached to them, the time required for oil flushing has been reduced.
The installation of the piping for the compressor unit’s body as well as its oil circuit system requires a high level of internal cleanliness. During the preparation of these oil pipelines before installation, as well as during the installation process itself, impurities such as solid contaminants and oxide scales present in the pipelines can significantly affect subsequent oil running-in procedures and individual unit tests. Therefore, it is necessary to carry out acid cleaning and passivation of the pipelines before oil circulation begins. Through this process, a dense oxide layer is formed on the inner walls of the oil pipelines, which extends their service life and enhances economic efficiency.

To ensure the high purity of lubricant oil, extremely high standards of cleanliness are required in the production processes. The degree of cleaning of the process equipment and pipelines installed affects directly the proper operation of the equipment. The retention of certain impurities in the process system can even lead to the inability to produce qualified products for an extended period of time, as well as pose safety hazards.
1. Remove contaminants such as weld slag, dust particles, and impure oils generated during pipeline installation to prevent contamination of the oil. Avoid contaminating the oil products. 2. Under the condition of oxides, it provides a good foundation for the formation of a passivation film, enabling the passivation film to be more dense and thus enhancing the passivation effect!
