在役天然气分离除尘设备性能评价

针对现有天然气分离除尘设备分离不彻底、除尘效率不高、评价困难等问题，利用3A分子筛吸附脱水和湍球水浴除尘原理，研制了橇装式天然气含水含尘检测装置。利用该检测装置对川东气田几十台次不同类型的分离除尘设备进行了检测。结果表明，现有分离除尘设备中，卧式气液分离器能很好地满足初分离需要，多管干式除尘器、过滤分离器分离性能较好，但对小直径粉尘分离效率仍然不高，其余类型分离除尘设备则性能较差，难以满足矿场分离除尘指标要求，亟待改进。

PERFORMANCE EVALUATION OF NATURAL GAS SEPARATION AND DEDUSTING FACILITY IN SERVICE

Because the natural gas separation and dedusting facilities in service do not work efficiently and hard to appraise, the skid-mounted water and dust detection device for natural gas was developed by using 3A molecular dehydration and turbulent ball water bath dedusting theory. Dozens of separation and dedusting facilities with different types in the Eastern Sichuan Gasfield have been detected by applying this detection device. The result shows that the horizontal gas-liquid separator can well meet the demand of initial separation. The multi-string dry-style dedustor and filter separator have better separation performance, whereas it is not efficient when separating small-diameter dust. Other separators have bad performances, which are hard to attain field separation and dedusting specification. Therefore, they need further improvement urgently.
