APPLICATION FOCUS ETHYLENE PRODUCTION FROM SHALE GAS EXAMPLES OF MARINE VAPOR RECOVERY SYSTEMS In ethylene production plants, it is essential to analyze process gases accurately and reliably to ensure safety and efficiency. These efficiencies can be achieved in a number of ways: • Shortening the residence time in the cracking furnace • Rapidly adapting to changing feed stocks • Improving combustion control • Optimizing fractionation • Improving combustion reliability Safety can also be improved through the use of fast, reliable process analysis technologies with high measurement availability. The increasing use of shale gas to provide the feedstock for ethylene cracking has required a new approach to gas analysis solutions within the production process, since feed gas quality is critical to the overall process. The fracked gas is processed and stripped of its ethane, which is then used to feed the cracker. Servomex is well placed to adapt its proven analysis for traditional ethylene production processes to provide an effective solution for ethylene production using ethane feedstock from shale gas.
