搓洗技术应用于联合站注水过滤器

随着油田的深度开采,采出水中含有的聚合物导致注水过滤器中的滤料板结情况时有发生.如何防止滤料板结,是石油行业水处理中面临的问题之一.目前在解决防止滤料板结问题中,江汉石油机械厂引用美国技术,开发研制了搓洗式核桃壳过滤器.该装置及技术与常规搅拌式反洗滤料相比,反洗强度大、效果好,能有效防止滤料板结.2004年,河南油田采油一厂引进此项专利技术,并在江河联合站的两台二级搅拌式核桃壳过滤器中改造应用.自动搓洗式过滤器,应用的目的在于进行自动化改造,提高设备管理水平,减轻操作者劳动强度,考查对比搓洗式反洗与搅拌式反洗效果,同时考查自控系统和阀件的性能稳定性.自2005年6月设备改造完成并投运以来,取得了非常好的效果.     

新型催化裂化活性剂

由中国石油大学（华东）化学化工学院与东营市石大宇光科技有限责任公司合作，成功地开发出新型YG-1720催化裂化活性剂，并完成了工业装置试验。与目前广泛应用的金属钝化剂相比，YG-1720催化裂化活性剂具有应用简单，抗结焦能力强，钝钒效果明显的优点，并可显著改善产品分布。     

国际石油合同中的风险与对策

石油公司从事跨国石油勘探开发活动，必然受到国际石油合同的影响和制约。国际石油合同包括租让制合同、产品分成合同、风险服务合同、回购合同、联合经营和国家石油公司私有化6类。石油合同风险分为地质风险、技术风险、财务风险、商业风险和政治风险5种类型。通过全面分析国际石油合同及其风险的类型和特点，认为在油气勘探开发项目的不同阶段风险管理的重点不同，石油公司必须建立科学的投资决策程序，采取定量与定性相结合的风险分析和投资决策方法，合理利用资源国财税制度等措施规避和降低风险，对中国的石油公司从事跨国石油勘探开发具有重要意义。     

超声波探伤仪的正确使用

在炼油厂、石油化工厂和发电厂等大型工厂,广泛使用超声波探伤仪来检查各种管道的损伤,以避免因腐蚀等原因而穿孔甚至爆裂,威胁安全生产。但必须充分认识它的优势和局限性,合理使用,才能做到事半功倍。超声波探伤仪可方便的测出加热炉管的裂缝、球形罐支柱耐火层内的腐蚀；基本上不受涂装和管内流体的影响。但对许多测定部位有具体要求,满足测定要求才能测出可靠的数据。如温度不能超     

Performance and Commercial Application of the Promoter LCC-A for Maximization of Propylene Yield

1 Introduction Propylene as an important feedstock for organic chemicals is mainly originated from steam cracking and catalytic cracking processes. During the FCC process the propylene content varies with the FCC catalyst and process technology adopted, resulting in significant difference in propylene concentration in the cracked product——LPG. The conventional FCC pro- cess generally gives a propylene yield of around 4%, while the FCC process with maximization of propylene yield can in…     

Study on Laboratory Method for Refining of SR Diesel Fuel

The method for refining the straight-run diesel fuel was studied in laboratory scale in order to make the acid number of diesel fraction comply with the standard while removing the naphthenic acids contained in diesel without causing environmental pollution. After comparing the effect of refining using three solvents, the isopropyl alcohol-HOA was specified as the best solvent. Meanwhile, the relationship between the acid number of diesel fraction and the amount of solvent used and the relationship between the concentration of solvent and temperature and the stability of diesel in terms of its acid number were also investigated. Experimental results had shown that when the mass fraction of the HOA-IPA solvent was 20% at a dosage of 17 mL of the solvent and a temperature of 30℃, the acid number of the refined diesel fraction was 0.015 mg KOH/g with a good stability of acidity in the diesel fraction,
