A series of separation steps produce fractions consisting of ethylene, propylene, a C4 fraction (e.g., butadiene), and pyrolysis gasoline (containing benzene, toluene, and xylenes). The gas mixture is rapidly cooled to 400 °C (or quenched) to stop the reaction, during which process high-...
This section concludes with some comments on the sampling strategies for forensic investigation of gasoline-impacted groundwater. Chemical fingerprinting of dissolved phase contamination derived from gasoline can be achieved using conventional PIANO fingerprinting methods and emerging methods. Conventional methods...
