C-98脱砷催化剂在工业装置上的应用情况 C-98脱砷催化剂已在国内石化企业如上海石化股份公司等单位5万吨/年催化丙烯工业装置脱砷单元上使用，可将丙烯中600～700ppb砷化物脱除至10ppb以下，净化后的丙烯满足聚丙烯工业装置的要求。该产品获得中石化科技进步三等奖，已在中石油大连石化、海南炼油厂、岳阳石化、九江石化、荆门炼油厂等单位聚丙烯装置上使用。 使用注意事项 进口原料中硫含量高于2ppm，也能用于脱砷，但对砷容有影响。 系统暂时性停车，应维持脱砷反应器压力，以防止反应器负压吸附空气中水分。如有必要可用干燥氮气置换反应器，并保压。 停车更换脱砷剂前，先用氮气置换反应器，带好防毒面具卸出废脱砷催化剂。 脱砷催化剂的砷容量不宜过高，一般控制在2%～5%，否则不利于回收处理。 售后服务 我院可提供对催化剂性能实时控制技术，对废催化剂回收，供冶炼厂处理。 |

我来试试 Applications of C-98 propylene de-arsenic catalyst in plants Propylene de-arsenic catalyst has been widely used by many domestic petrochemical companies, SINOPEC SHANGHAI PETROCHEMICAL COMPANY LIMITED’s 50,000 tons/a propylene production line, for example, adopts C-98 propylene catalyst in its de-arsenic unit. The content of arsenide was decreased from 600-700ppb to less than 10ppb, and the de-arsenic propylene could satisfy the requirements of Polypropylene plant. The product awarded Third prize of scientific and technological progress of Sinopec, and was promoted the use in affiliates of China National Petroleum Corporation, Dalian Petrochemical, Hainan Refinery, Yueyang Petrochemical, Jiujiang Petrochemical, Jingmen Refinery etc. Cautions The raw material imported with Sulphur content higher than 2ppm, can used as de-arsenic catalyst but less effection. The pressure in de-arsenic reactor should be maintained when the system breaks Temporarily to prevent the reactor from moisture absorption. Dried N2 may be used as a substitution and pressure maintainer in reactor if necessary. The reactor should be emptied by dried N2 before system stop to renew propylene de-arsenic catalyst. Gas mask should applied when handling the de-arsenic catalyst waste. Content of arsenic in de-arsenic catalyst should not be too high in favor of recycling, commonly controlled at 2-5%, After-sales service We can provide the real-time controlling technique for propylene de-arsenic catalyst, and services for withdrawing and disposal of catalyst wastes.

the application of C-98 Arsenic removal catalyst in industrial devices the application of C-98 Arsenic removal catalyst has already been applied in domestic petrochemical enterprises such as the 50,000 tons/year propylene plant catalytic arsenic removal unit in Shanghai Petrochemical's shares. Using this Arsenic removal catalyst , the 600～700ppb arsenic compounds in Propylene can be reduced to lower than 10ppb, which meets the requirement for industrial production of Polypropylene. This catalyst was awarded third award of scientific and technological progress in Sinopec and has already been applied in indtustrial Polypropylene production devices in PetroChina Dalian Petrochemical, Hainan refinery, Yueyang Petrochemical, Jiujiang petrochemical and Jingmenoil refinery, etc. |

我从后面翻一部分吧，二楼的。 使用注意事项 Note for use: 进口原料中硫含量高于2ppm，也能用于脱砷，但对砷容有影响。 The content of sulfer in the imported raw materials, more than 2 ppm, could used for arsenic removal, but affected the arsenic capacity. 系统暂时性停车，应维持脱砷反应器压力，以防止反应器负压吸附空气中水分。如有必要可用干燥氮气置换反应器，并保压。 The presure of reactor for arsenic removal should be maintained at a certain value when the system temporarilly parked, preventing from the negative presure causing water absorption. If necessarily, nitrogen dryer exchange reactor could be used with keeping presure. 停车更换脱砷剂前，先用氮气置换反应器，带好防毒面具卸出废脱砷催化剂。 Using nitrogen exchange reactor and wearing gas mask, wasted arsenic removal catalysts would be removed before arsenic removal catalysts were replaced. 脱砷催化剂的砷容量不宜过高，一般控制在2%～5%，否则不利于回收处理。 Arsenic content should not be so high, generally at the range between 2% and 5%. Less it would not make nothing for recycling. 售后服务： After-Sales Service： 我院可提供对催化剂性能实时控制技术，对废催化剂回收，供冶炼厂处理。 The technology of real-time catalysts performance controlling and wasted catalysts recycling offered to smelter to deal with could be provided by our institute.  |

Cautions Can be used for arsenic removal when Sulphur content of the raw material is higher than 2ppm, but the As removal efficiency will be slightly affected. The pressure in de-arsenic reactor should be maintained when the system endures a temporary break in order to prevent the moisture absorption of reactors due to negative pressure. Dry nitrogen replacement reactor can be used if neccesary and the pressure should be maintained. Dry nitrogen replacement reactor should be used before replacement of catalyst. Gas mask should be equipped when handling the de-arsenic catalyst waste. the arsenic content in the de-arsenic cataclyst should be in the range of 2%-5%, otherwise the recycling efficiency will be influenced After-sales service We can provide services on the real-time controlling technique for the catalyst, as well as the recovery and disposal of catalyst wastes |
