洛阳石化2号催化装置为同轴式运行模式,2011年1月至2012年8月,采取了停用E1315A-D及优化空冷风机运行,降低水消耗,烟机发电,优化蒸汽网络等节能措施。2011年9月大检修后,实施解吸塔底热源改造、E1303与E1304水冷器改串联等节能项目。在原料劣质化程度加重的情况下,投用终止剂,适当提高剂油比,提高原料预热温度,改善原料雾化效果,控制好催化剂性能,试用CRA降焦助剂,使生焦率由7.0%降至6.5%;同时做好闪蒸塔原料的优化,以确保装置能耗的降低。2012年6～7月装置低负荷运行情况下,采取了投用预提升干气的优化措施,投用预提升干气不仅可以降低蒸汽能耗,而且可以抑制重金属脱氢反应,降低装置生焦率,进一步降低装置能耗。通过以上节能优化,装置能耗从2011年1月的57.52kg标油/t降至2012年8月的41.80kg标油/t。
Luoyang Petrochemical 2 catalytic device for the coaxial operation mode, from January 2011 to August 2012, taken to stop E1315A-D and optimize air-cooled fan operation, reduce water consumption, power generation hoods, steam and other energy-saving measures to optimize the network . In September 2011 after major overhaul, the implementation of heat transfer desorption tower, E1303 and E1304 water coolers and other energy-saving projects in series. In the case of worsening of raw materials, the dosage of terminator, appropriate increase of oil to oil ratio, increase of material preheating temperature, improve the atomization effect of raw materials and control of catalyst performance, try CRA coke reducing aid, 7.0% down to 6.5%; at the same time make the optimization of the raw material of the flash tower to ensure that the energy consumption of the device is reduced. Under the condition of low load operation from June to July in 2012, the optimization measures of using pre-lifting dry gas are put forward. Using pre-lifting dry gas can not only reduce the energy consumption of steam, but also restrain the heavy metal dehydrogenation reaction and reduce the raw coke Rate, to further reduce the device energy consumption. With the above energy saving optimization, the energy consumption of the plant was reduced from 57.52 kg of standard oil / t in January 2011 to 41.80 kg of standard oil / t in August 2012.
