Processor for removing contaminants from a compressor in a methanol to olefin separation system

A process for removing contaminants from a compressor in a methanol to olefin separation system, the process comprising the steps of:

• (a) compressing an effluent in the compressor, the compressor having an inlet and an outlet and an inner compressor surface, the compressing occurring under conditions effective to form a contaminant on the inner compressor surface, wherein the contaminant causes a vibration in the compressor;
• (b) injecting a contaminant-removal medium into the compressor;
• (c) contacting the contaminant-removal medium with the contaminant under conditions effective to remove the contaminant from the inner compressor surface thereby forming a mobile contaminant;
• (d) removing the mobile contaminant from the compressor;
• and
• (e) monitoring the vibration.

A process for removing contaminants from a compressor in a methanol to olefin separation system, the process comprising the steps of:

• (a) contacting a methanol to olefin product fraction with a quenching medium in a Quench Tower under conditions effective to form a Quench Tower overhead stream and a Quench Tower bottoms stream, wherein the Quench Tower overhead stream comprises light olefins, and wherein the Quench Tower bottoms steam comprises spent quench medium and a wash oil;

• (c) injecting the wash oil into a compressor to remove contaminant from the compressor, thereby forming a mobile contaminant;
• and
• (d) removing the mobile contaminant from the compressor.
