| Abstract: | The seal structure of the recycle gas compressor in LLDPE Plant is mechanical seal plus float ring structure. After sealing medium leakage, lubricant oil gas can react with the mixed gas of reaction gases that enter into reaction cycle system, which affects the activity of catalyst. Modification was made after model selection and calculation was made to the dry gas seal is made. The dry gas seal after modification has outstanding advantage and can meet production requirement. |
