【摘要】：壓縮天然氣(CNG)氣質(zhì)對我國天然氣產(chǎn)業(yè)發(fā)展具有重要意義,目前我國天然氣質(zhì)量標(biāo)準(zhǔn)同國外標(biāo)準(zhǔn)相比仍有一定差距。大慶地區(qū)處于我國東北部,因多種原因,壓縮天然氣氣質(zhì)更低于全國平均標(biāo)準(zhǔn),其脫硫脫水水平已然成為制約行業(yè)發(fā)展的重要因素。CNG加氣母站脫硫脫水工藝及脫水指標(biāo)是否合格直接影響整個燃氣企業(yè)能否平穩(wěn)運行。一是脫硫指標(biāo)不合格不僅對輸運管路、設(shè)備及加氣車輛燃油動力系統(tǒng)造成腐蝕,而且影響后續(xù)加工(如導(dǎo)致催化劑中毒),為設(shè)備設(shè)施的平穩(wěn)運行埋下嚴(yán)重安全隱患,甚至威脅人身安全;二是北方地區(qū)冬季寒冷漫長,如果脫水指標(biāo)不合格,設(shè)備必然出現(xiàn)凍堵情況,嚴(yán)重影響母子站安全運行和居民平穩(wěn)供氣。本文以大慶中石油昆侖燃氣有限公司紅崗母站為研究對象,重點開展脫硫脫水設(shè)備工藝優(yōu)化研究,對設(shè)備改造、分子篩選型、填料配比及參數(shù)調(diào)整等方面進行優(yōu)化,最終獲得東北高寒地區(qū)設(shè)備運行參數(shù)最佳配置,確保設(shè)備平穩(wěn)高效運行。通過以上研究可以獲得加氣站脫硫脫水系統(tǒng)性能及設(shè)備優(yōu)化選型的理論支撐,為加氣站設(shè)計、建設(shè)和運行管理提供科學(xué)依據(jù)和實際參考。
[Abstract]:The quality of compressed natural gas (CNG) is of great significance to the development of natural gas industry in China, and there is still a certain gap between the quality standards of natural gas in our country and that of foreign countries. The quality of compressed natural gas is even lower than the national average. The level of desulphurization and dehydration has become an important factor restricting the development of the industry. Whether the desulfurization and dehydration process and dehydration index of CNG filling master station are qualified or not directly affects the smooth operation of the whole gas enterprise. Equipment and fuel power systems of aerated vehicles cause corrosion, and affect subsequent processing (such as poisoning of catalysts, serious safety risks for the smooth operation of equipment and facilities, and even threats to personal safety; second, long cold winters in northern areas, If the dehydration index is not up to standard, the equipment will inevitably be frozen and blocked, which will seriously affect the safe operation of the mother-child station and the stable gas supply to the residents. This paper takes Honggang Mother Station of Daqing PetroChina Kunlun Gas Co., Ltd as the research object. The process optimization of desulphurization and dehydration equipment was carried out, and the equipment modification, molecular sieve selection, filler ratio and parameter adjustment were optimized. Finally, the optimal configuration of equipment operation parameters was obtained in the northeast alpine region. Through the above research, the theoretical support for the performance of desulfurization and dehydration system and the optimal selection of equipment can be obtained, which can provide scientific basis and practical reference for the design, construction and operation management of the gas filling station.
