摘要 对中国石油化工股份有限公司洛阳分公司蜡油加氢处理装置影响氢耗的因素进行了分析并提出改进建议。结果表明:蜡油加氢处理装置氢耗随原料油密度、原料油硫含量和反应温度升高而增大。原料油密度在891~908 kg/m3时,化学氢耗为5.15~6.95 kg/t;原料油硫质量分数为0.674%~1.097%时,化学氢耗为4.25~6.28 kg/t;反应温度为299~337℃时,化学氢耗为5.31~5.90 kg/t。为了降低氢耗,热高压分离器温度选择在240~260℃,冷高压分离器操作温度控制在45~55℃,以降低循环氢溶解损失。同时,装置应定期进行闭灯检查以防止装置氢气泄漏。在满足生产的条件下,尽量减少排放废氢气。 The factors affecting the hydrogen consumption of wax oil hydrotreating unit in SINOPEC Luoyang Company are analyzed and effective measures are recommended.The results show that the hydrogen consumption of the wax oil hydrotreating unit increases with rise of feedstock density,sulfur in feedstock and reaction temperature.When the feedstock density is 891~908 kg/m3,the chemical hydrogen consumption is 5.15~6.95 kg/t crude oil.When the sulfur in feedstock is 0.674%~1.097%,the chemical hydrogen consumption is 4.25~6.28 kg/t crude oil.When reaction temperature is 299~337 ℃,the chemical hydrogen consumption is between 5.31 and 5.90 kg/t crude oil.To reduce hydrogen consumption,the 240 and 260 ℃ temperature should be selected for hot high-pressure separator and the operating temperature of cold or high-pressure separator should be controlled at 45 ℃ to 55 ℃ to reduce the loss of dissolved recycle hydrogen.In addition,the lights in the unit are tuned off for regular examination to prevent hydrogen from leaking from the unit.Waste hydrogen release should be minimized under operating conditions.
