DECREASE OF HARMFUL ATMOSPHERIC EMISSION AT OIL AND GAS CONDENSATE FIELDS OWING TO APPLICATION OF JET DEVICES
Abstract and keywords
Abstract (English):
Actuality of atmosphere protection from pollution by low-pressure flare gas as well as possibility of solving of this problem owing to application of liquid-gas jet devices with two-phase active flow are shown. Results of experimental investigations of ejectors with active two-phase flow at mass fraction of gas in active flow more than 0.003 are presented. Significant error of calculation results using approach which does not take into consideration interaction of active gas and liquid at mixing chamber initial zone is observed. It is shown that use of momentum conservation equation for liquid and gas flows at mixing chamber initial zone enables to take into account influence of active gas energy and to obtain satisfactory agreement of calculation and experimental data at mass fraction of gas in active flow more than 0.003. The obtained results were used for designing of liquid-gas jet devices with active two-phase flow for low-pressure flare gas utilization at Kokdumalak oil and gas condensate field.

Keywords:
atmosphere pollution, flare gas, utilization, jet devices, two-phase active flow.

1. Введение в проблему

Предприятия нефтегазового комплекса относятся к крупнейшим загрязнителям атмосферы Земли. По разным оценкам [1], в атмосферу нашей планеты ежегодно выбрасывается от 40 до 90 млн т различных углеводородов. Основными компонентами этих выбросов являются легкие углеводороды метанового ряда C1…C5 и сероводород H2S, присутствующий в нефти в значительном количестве. При этом наибольший объем выбросов (более 20 млн т/год) приходится на метан CH4. Углеводороды оказывают негативное воздействие на все живые организмы, а метан приводит к усилению парникового эффекта на нашей планете. Так, согласно [2], вклад СН4 в усиление парникового эффекта в настоящее время составляет около 18% и по этому показателю он уступает только углекислому газу.
