Proven Track Record
The reliable Taechin Py-Gas Reflux sample conditioner cleans hot, Dirty and/or wet gas samples at the Process tap and delivers a reproducible Sample to a variety of analyzers, Including mass spectrometers and gas Chromatographs, for physical property or Composition measurement. Designed on Simple chemical engineering principles of Fractionation combined with controlled Sample velocity and temperature Differential, it enables analysis of lighter Hydrocarbons by removing liquid mist or Water, heavy particulates and fine Carbons from complex, hot hydrocarbon Gas mixtures. Practical for a variety of Applications, the Py-Gas conditions The sample via cooling and refluxing and is ideal for treating condensables, polymers and particulates.
Application-Specific Models
All four Electric Py-Gas models are suitable for hazardous area use and are virtually maintenance-free:
- EPG 3000 - Most often used in ethylene cracking furnace sampling applications (i.e., ethane/propane and naphtha/gas oil cracking)
- EPG 5000 - Reliably samples the stack of a FCCU regenerator and features an elongated cooling section and additional density packing to handle higher temperatures
- EPG 6000 - Used in applications similar to those of the EPG 3000 But does not generally handle as much volume as the other two models
- EPG 7000 - Used for the same applications as the EPG 3000 and offers the capacity to handle twice the volume
Self-Cleaning Design
The Py-Gas was developed to sample a reactive pyrolysis gas online without the problems associated with conventional sampling systems which tend to plug rapidly, suffer from a high degree of unreliability, and require extensive and frequent maintenance. Designed to drop out condensables and wash them back into the process together with any solids, this self cleaning unit provides a saturated, cooled and representative sample for the required measurement
