Opis:
The EST system – emission-free sewage transport is one of many methods used to counteract and limit the formation of hydrogen sulfide in the sewage system. EST method is the environment and human friendly, and effective at the same time. This solution applies aeration and flushing of pressure pipelines using compressed air with closed vent valves. The paper presents the results of field tests of the EST system, which also verified previous laboratory tests carried out in a broader range.The tests were carried out on two different delivery pipelines (Object-1, Object-2), consisting of several kilometers long sections Pump Station – Expansion well with hydrogen sulfide concentration measurement. The results show that the EST system is an effective solution for controlling hydrogen sulfide in a pressure sewage system. The application of the EST system caused an immediate decrease in H2S concentration under 50 ppm. The measurements were taken in the expansion well, where short-term outbursts of large loads of hydrogen sulfide were observed during sewage pumping. Purges carried out 1-2 times a day, caused a decrease in instantaneous gas load (from the average level of 758 mg H2S/pump cycle at Object-1 to 15 mg H2S/cycle and from 3 914 to 322 mg H2S/cycle at Object-2).Results of field studies have also shown that individual optimization of the EST system operation for a selected section of the pressure sewage system (length of the aeration cycle and its frequency during the day), may control the concentration of H2S. The EST system, reducing the concentration of H2S by over 90%, ensures the safety of sewage system operation and decreases its impact on the surrounding environment.
