How to Solve Off-Spec Propane Issues

Updated: Feb 12, 2020

Product specification failures cause severe economic hardships due to the logistical management of the propane and the costs associated with processing the propane internally. Utilizing new technology to eliminate methyl and ethyl mercaptans in sulfur loading can help alleviate these issues.

Rejected propane - when used as feedstock - lowers the efficiency of the plant and increases maintenance costs. Propane contamination issues cause plants to fail propane specification targets such as copper strip tests and freeze valve tests. The propane must pass the pipeline operator’s requirements resulting from corrosion standards and fuel characteristics. When the company experiences a specification failure, the pipeline operator reverses the flow, redirecting the off-spec propane back to the plant, costing them millions of dollars. Causes of Copper Strip Failures in Propane:

  • Reactive sulfur

  • Hydrogen sulfide (H2S)

  • Elemental sulfur

  • Carbonyl sulfide (COS)

  • Mercaptans

Growing Industry Need to:

  • Manage a wide variation in contaminant concentrations

  • Meet propane quality goals and requirements

  • Improve product value

  • Manage changes in production

  • Increase plant efficiency

  • Reduce unnecessary maintenance expenses
