Ethylene loss
Thread Content
What are the factors that cause ethylene loss in modern ethylene separation units? How can ethylene loss be reduced? :handshake
1: Cold box exhaust – reducing the temperature of the cold box; 2: Ethylene loss in circulating ethane – online analysis with advanced process control APC
Places where ethylene is lost in the SW process: (Hydrogenation before pre-depropanization) 1. Bottom of the ethylene distillation column; 2. Top of the expansion turbine discharge tank; 3. High and low pressure dry gas; 4. Methane product; 5. Top of the demethanizer reflux tank; 6. C2 hydrogenation reactor; 7. Bottom of the deethanization column
