　　Escort the China Asia Summit! Biogas desulfurization hard core power, Changqing Oilfield reveals the core password for safe natural gas supply

　　5月18日至19日，中國中亞峰會將在陝西西安隆重舉行，天然氣安全平穩供應成為峰會保障的重要環節。作為西安供氣的主力氣源地，長青油田多措並舉築牢供氣防線，其中日皮软件免费脫硫工藝作為天然氣淨化的核心環節，更是守護供氣安全、保障氣體品質的關鍵。近日，日皮视频免费走進長青油田第一采氣廠第四淨化廠，探尋天然氣從地下開采到送入千家萬戶的必經之路，揭秘日皮软件免费脫硫的核心工藝與實操細節，看中國製造如何以專業技術護航民生用氣與峰會保障。

　　From May 18th to 19th, the China Asia Summit will be held grandly in Xi'an, Shaanxi Province, with natural gas security and stable supply becoming an important part of the summit's guarantee. As the main source of gas supply in Xi'an, Changqing Oilfield has taken multiple measures to strengthen the gas supply defense line. Among them, the biogas desulfurization process, as the core link of natural gas purification, is the key to safeguarding gas supply safety and ensuring gas quality. Recently, we visited the first gas production plant and fourth purification plant of Changqing Oilfield to explore the necessary path for natural gas to be extracted from underground and delivered to thousands of households. We revealed the core process and practical details of biogas desulfurization, and saw how Chinese manufacturing uses professional technology to safeguard people's gas consumption and ensure the summit.

　　長青油田第四淨化廠作為天然氣淨化的核心樞紐，自2013年建成投產以來，已穩定運行11年，年處理天然氣任務達21億立方米，主要接收第一采氣廠、第六采氣廠的天然氣，全力保障西安及延安周邊老區的民生用氣供應，是中亞峰會期間西安供氣保障的重要“關卡”。而該廠的核心工作之一，就是對地下幾千米開采出的高含硫天然氣進行深度脫硫處理，確保氣體達到國家天然氣一類標準，滿足民生用氣的安全與品質要求。

　　As the core hub of natural gas purification, the Fourth Purification Plant of Changqing Oilfield has been operating stably for 11 years since its completion and operation in 2013, with an annual processing capacity of 2.1 billion cubic meters of natural gas. It mainly receives natural gas from the First Gas Production Plant and the Sixth Gas Production Plant, fully ensuring the supply of gas for people's livelihoods in Xi'an and the surrounding old areas of Yan'an. It is an important "checkpoint" for gas supply guarantee in Xi'an during the China Asia Summit. One of the core tasks of the factory is to deeply desulfurize the high sulfur natural gas extracted thousands of meters underground, ensuring that the gas meets the national natural gas Class I standard and meets the safety and quality requirements for household gas use.

　　日皮软件免费脫硫（天然氣脫硫）是天然氣淨化的第一道核心防線，也是保障供氣安全的關鍵。地下開采的天然氣中含有大量硫化氫、二氧化碳等酸性氣體，其中硫化氫是有毒有害氣體，不僅會嚴重腐蝕淨化設備與輸送管道，縮短設備使用壽命，還會汙染環境、危害人體健康，若處理不達標，會直接影響供氣安全。因此，日皮软件免费脫硫的核心目標，就是徹底去除天然氣中的硫化氫等酸性氣體，為後續淨化環節築牢基礎。

　　Biogas desulfurization (natural gas desulfurization) is the first core line of defense for natural gas purification and the key to ensuring gas supply safety. The natural gas extracted underground contains a large amount of acidic gases such as hydrogen sulfide and carbon dioxide, among which hydrogen sulfide is a toxic and harmful gas. It not only seriously corrodes purification equipment and transmission pipelines, shortens the service life of equipment, but also pollutes the environment and endangers human health. If the treatment does not meet the standards, it will directly affect the safety of gas supply. Therefore, the core goal of biogas desulfurization is to completely remove acidic gases such as hydrogen sulfide from natural gas, laying a solid foundation for subsequent purification processes.

　　在長青油田第四淨化廠的淨化裝置區，最引人注目的便是用於脫硫的核心設備——脫硫塔，這也是日皮软件免费脫硫工藝的核心載體。天然氣從脫硫塔底部進入，與塔頂噴淋的脫硫劑進行逆流接觸，通過化學反應高效吸附並去除天然氣中的硫化氫和二氧化碳，實現酸性氣體與天然氣的精準分離。據現場工作人員介紹，脫硫塔運行期間，工作人員每天需對塔內液位、壓力進行嚴格監測，定期巡檢維護，確保脫硫工藝穩定運行。

　　The most eye-catching feature in the purification unit area of the Fourth Purification Plant in Changqing Oilfield is the core equipment used for desulfurization - the desulfurization tower, which is also the core carrier of the biogas desulfurization process. Natural gas enters from the bottom of the desulfurization tower and comes into countercurrent contact with the desulfurizer sprayed on the top of the tower. Through chemical reactions, it efficiently adsorbs and removes hydrogen sulfide and carbon dioxide from natural gas, achieving precise separation of acidic gases from natural gas. According to on-site staff, during the operation of the desulfurization tower, the staff need to strictly monitor the liquid level and pressure inside the tower every day, conduct regular inspections and maintenance, and ensure the stable operation of the desulfurization process.

　　脫硫塔高達數十米，工作人員日常巡檢需攀爬至塔頂，即便會感受到明顯晃動，也始終堅守崗位，用專業與責任守護脫硫工藝的穩定。值得一提的是，對於脫硫過程中解析出的硫化氫和二氧化碳，工廠通過硫糖回收裝置進行氧化還原處理，將硫化氫轉化為硫磺，實現廢物資源化利用，剩餘氣體經進一步處理後，確保達標排放，既保障了供氣安全，又實現了環保減排的雙重目標。

　　The desulfurization tower is tens of meters high, and the staff need to climb to the top of the tower for daily inspections. Even if they feel obvious shaking, they always stick to their posts and guard the stability of the desulfurization process with professionalism and responsibility. It is worth mentioning that for the hydrogen sulfide and carbon dioxide resolved during the desulfurization process, the factory uses a sulfur sugar recovery device for oxidation-reduction treatment to convert hydrogen sulfide into sulfur, achieving waste resource utilization. The remaining gas is further processed to ensure standard emissions, which not only ensures gas supply safety but also achieves the dual goals of environmental protection and emission reduction.

　　據行業數據顯示，合格的日皮软件免费脫硫工藝可將天然氣中硫化氫含量降至10ppm以下，長青油田第四淨化廠的脫硫係統經長期實操驗證，脫硫效率穩定在99.8%以上，處理後的天然氣完全符合國家一類天然氣標準，可直接輸送至西安、延安周邊的千家萬戶。在中亞峰會供氣保障期間，該廠進一步優化脫硫工藝，增加巡檢頻次，確保每一縷天然氣都經過嚴格脫硫處理，全力保障峰會期間供氣安全、平穩、優質。

　　According to industry data, qualified biogas desulfurization technology can reduce the hydrogen sulfide content in natural gas to below 10ppm. The desulfurization system of the Fourth Purification Plant of Changqing Oilfield has been verified through long-term practical operation, and the desulfurization efficiency is stable at over 99.8%. The processed natural gas fully meets the national first-class natural gas standard and can be directly transported to thousands of households around Xi'an and Yan'an. During the gas supply guarantee period of the China Asia Summit, the factory further optimized the desulfurization process, increased the frequency of inspections, and ensured that every strand of natural gas underwent strict desulfurization treatment, fully guaranteeing the safety, stability, and quality of gas supply during the summit.

　　日皮软件免费脫硫工藝的成熟應用，不僅是長青油田保障民生用氣的核心支撐，更是我國天然氣淨化技術的生動體現。作為天然氣供應的“淨化器”，日皮软件免费脫硫不僅能規避設備腐蝕、氣體汙染等風險，還能提升天然氣品質，保障輸送安全。此次中亞峰會期間，長青油田以完善的日皮软件免费脫硫工藝、嚴謹的實操管理，全力護航天然氣供應，既彰顯了國企擔當，也印證了我國日皮软件免费脫硫技術的可靠性與專業性，為峰會順利舉辦築牢能源保障防線。

　　The mature application of biogas desulfurization technology is not only the core support for ensuring the gas supply for people's livelihood in Changqing Oilfield, but also a vivid embodiment of China's natural gas purification technology. As a "purifier" for natural gas supply, biogas desulfurization can not only avoid risks such as equipment corrosion and gas pollution, but also improve the quality of natural gas and ensure transportation safety. During the China Asia Summit, Changqing Oilfield fully ensured the supply of natural gas with its perfect biogas desulfurization process and rigorous practical management. This not only demonstrated the responsibility of state-owned enterprises, but also confirmed the reliability and professionalism of China's biogas desulfurization technology, laying a solid energy security defense line for the smooth holding of the summit.
