The Py-Gas is an on-line sample conditioner designed for difficult sample conditioning situations such as the following:
- Hot and dirty gases
- Pyrolysis gases
- Liquid mists or water removal
- Wet, dirty gases
- Heavy particulate removal
- Fine carbon removal
The initial sample problem addressed by the Py-Gas was in gas/liquid feedstock for a cracking furnace producing ethylene. The problem was to sample a reactive pyrolysis gas to remove solids, water, and heavy oils from a complex, hot hydrocarbon gas mixture on-line so that the lighter hydrocarbons could be analyzed by a gas chromatograph.
Under such conditions, conventional sampling systems tend to plug rapidly, suffer from a high degree of unreliability, and require extensive and frequent maintenance. Py-Gas successfully overcame these difficulties while providing a saturated, cooled, and representative sample for the required measurement.
The basic design of the Py-Gas uses chemical engineering principles to drop out the condensable and wash them back into the process together with any solids resulting in a self-cleaning and maintenance free unit. From this basic design, a whole family of Py-Gas sample conditioners have been developed to address various difficult sample conditioning applications.
