SAMPLING AND ANALYSIS METHOD TO ACHIEVE A DETAILED ANALYSIS OF A REACTOR EFFLUENT

摘要

The present invention relates to a method suitable for establishing an analysis of a reactor effluent which is gaseous in process conditions and comprises a gas phase and a liquid phase after cooling, comprising : providing a reactor producing a gaseous effluent at a temperature of at least about 100 °C and a pressure ranging from 0.05 MPa to 10 MPa which comprises at least one gaseous phase and one liquid phase after cooling, providing a sampling vessel having connecting means capable to be filled with a sample of the above gaseous effluent and keep said sample, putting said sampling vessel under vacuum, connecting said sampling vessel to the outlet of the reactor containing the effluent gas to fill said sampling vessel with a sample of the effluent gas, disconnecting the sampling vessel, cooling it to get a gas phase and a liquid phase, determining the composition of the gas phase, sampling vessel pressure, sampling vessel volume and sampling vessel temperature and calculating the mass of the gas phase therefore, determining the liquid phase mass by weighing of total sample and subtraction of the gas mass, determining the detailed composition of the liquid phase by any means, determining the detailed composition the reactor effluent by combining these data.
