Further exploration of the liquid injection filter issue in screw compressors

Thread Content

As for the problems identified in the previous post, I speculate the following as their causes: 1. The filter element has been in use for too long, which caused it to rust and reduced its permeability. 2. Rust is present in the impurities, which may be in the pipes or in the gas-liquid separation tank. 3. During the filter switching process, a considerable amount of oil and black substances were observed. The presence of rust makes oil contaminants more likely to coking into large particles. The following methods were used to provide some relief. 1. Perform multiple replacements of the deionized water in the gas-liquid separator (during replacement, raise the liquid level to its highest point and drain the liquid from the lower part). Note: When opening the valve, start by opening it halfway to create vibrations inside the pipe, which will help lift out rust or other dense impurities. Then open the valve fully to drain the liquid – this gives the best results. ) 2. Replace the filter element with stainless steel to extend its service life. 3. Regularly replace the demineralized water in the separation tank to remove particulates. 4. Propose changing the gas composition to the upstream device. I hope all netizens can offer their guidance!
