 Abstract
The paper approaches automation problems associated with two-phase separators from oil rigs. Two- phase separators issues and conventional automation were analyzed. There were studied the trends and progresses in the field of two-phase separators automation. In addition to monitoring and control classical structures, the systems which estimate the water content in oil are of present interest. This paper critically examines the systems that perform on-line measurement of the amount of water in oil. The investigated device is EASZ-1 Water in Oil Monitor, from EESIFLO. There are evaluated the performance of both the transducer and the effects of its use in the oil industry.


 Rezumat
În lucrare sunt abordate probleme ale automatizare a separatoarelor bifazice utilizate în schelele petroliere. Autorii au analizat atât problematica separatoarelor bifazice cât şi a automatizării tradiţionale. În raport cu această ultimă variantă, autorii au studiat tendinţele şi progresele în domeniul automatizării separatoarelor bifazice. Astfel, pe lângă structurile clasice de reglare şi monitorizare sunt actuale şi sistemele de estimare a cantităţii de apă din ţiţei. Lucrarea analizează critic sistemele de măsurare a on-line cantităţii de apă din ţiţei. Traductorul investigat este EASZ-1, produs de firma EESIFLO. Sunt evaluate atât performanţele traductorului cât şi efectele utilizării acestuia în industria petrolieră.
