Estimating the term…
The present invention is intended to take a sample of an emulsion circulating in a line. The emulsion is momentarily diverted from the main circulation line 1 thereof to a bypass line 2. By restoring circulation of the emulsion in main line 1, an emulsion sample still present in bypass line 2 is confined under pressure. The emulsion sample is then stabilized according to a well-known method. Since the size and the distribution of the drops no longer evolve with time, the sample can be observed and analyzed after sampling. The invention more particularly applies to the field of petroleum industry and it is notably intended to take a sample of a petroleum effluent in form of an emulsion at wellheads.
A process for taking a sample, with a view to analysis, of an emulsion circulating in a main line, comprising the following stages:
A device for taking a sample under pressure of an emulsion circulating in a main line, comprising a bypass line that joins said main line, distribution means for feeding the emulsion into said main line or said bypass line, said bypass line comprising a sleeve provided with a valve at each end thereof and with at least one injection means for injecting a stabilization product, said sleeve exhibiting a continuity in its inner section in relation to said bypass line and the sleeve being provided with unions for readily disconnecting it from said bypass line.
