据俄罗斯油气网10月3日消息称，俄罗斯专利局注册了西布尔子公司NIPIGAZ和SiburTyumenGaz的专有权，发明一种从分子硫、硫化合物和二氧化碳中提纯液化石油气的方法。
该技术的独特之处在于，通过使用一种特殊的吸收剂，可以同时从酸性组分和元素硫中分离出大量轻质烃(BFLH)。 NGL伴生石油气加工后的产物，是一种LPG混合物。事实是，现有的技术要么不允许在一个技术单元中进行一步提纯，要么不提供所需浓度的酸性成分和单质硫。
简而言之，新技术将大大减少和简化NGL的提纯过程。
本发明可用于石油、天然气、天然气加工、炼油、石化、化工等行业。
这项新技术已经在西布尔的企业中得到了应用。从西伯利亚西部的一些油田，South-Balyksky天然气处理厂SiburTyumenGaz收到含高硫化合物和二氧化碳的伴生气。因此，在Yuzhno-Balykskoye气体处理厂，实施了一项建设深度提纯BFLH装置的新项目，该项目自2018年开始实施，并在其上测试了一项新技术。总设计师是NIPIGAZ。2017年进行的新安装和现代化改造，使Yuzhno-Balykskoye GPP在2018年创造了NGL生产的历史记录。
新安装的深度提纯NGL的工作是24小时不间断的。实施的深度提纯BFLH装置产能高达150万吨/年。一项新的独特技术的应用可以保护输送BFLH的管道免受腐蚀性杂质的污染，并满足俄罗斯最大的石化企业——ZapSibNeftekhim的原料需求。

SIBUR patented a unique technology for the purification of LPG from sulfur and other impurities
Rospatent registered the exclusive right of the SIBUR subsidiaries - NIPIGAZ and SiburTyumenGaz - to invent a method for purifying liquefied petroleum gases from molecular sulfur, sulfur compounds and carbon dioxide.
The uniqueness of the technology lies in the simultaneous purification of a wide fraction of light hydrocarbons (BFLH) from acidic components and from elemental sulfur through the use of a special absorbent. NGL is a product of the processing of associated petroleum gas and is a mixture of LPG. The fact is that existing technologies either do not allow such cleaning in one technological unit in one step, or do not provide the required concentrations of acidic components and elemental sulfur at the outlet.
In simple terms, the new technology will significantly reduce and simplify the process of cleaning NGL.
The invention can be used in the oil, gas, gas processing, oil refining, petrochemical, chemical and other industries.
The new technology is already being used at SIBUR's enterprise. From some of the fields in Western Siberia, the South-Balyksky Gas Processing Plant SiburTyumenGaz receives associated gas with a high content of sulfur compounds and carbon dioxide. Therefore, at the Yuzhno-Balykskoye gas processing plant, a new project for the construction of a deep-cleaned BFLH installation, in force since 2018, was implemented, on which a new technology was tested. The general designer was NIPIGAZ. The new installation and the modernization carried out in 2017 allowed the Yuzhno-Balykskoye GPP to set a historical record for the production of NGL in 2018.
The work of the new installation of deep cleaning NGL goes in continuous round-the-clock mode. The capacity of the implemented deep-cleaned BFLH installation is up to 1.5 million tons / year. Application of a new unique technology allows protecting pipelines transporting BFLH from corrosive impurities and satisfying raw material requirements for the facilities of the largest petrochemical complex in Russia - ZapSibNeftekhim.
