Description:

In the cold end section of each olefin cracking plant are two large refrigeration compressors. The compressors use oil in their seal system to help prevent gas from escaping to the atmosphere. This seal oil becomes mildly contaminated by dissolved gases and was being discharged to the oil-water sewer.

P2 Application:

Tests showed that a heat and nitrogen purge could regenerate the oil. Purged oil could be recycled directly back to the compressor oil reserve and tests showed no deterioration in physical properties over time.

Environmental Benefits:

Recycling the seal oil reduced flow of waste oil by about 150 gallons a day.

Details of Reductions

Additional Information :

The reduction in lube oil purchases amounted to $62,000 a year.
