原油加工方案的确定及百万吨级/年原油蒸馏塔的设计 摘 要 石油是国家重要的能源物质，石油化工产品是国民经济建设与人民生活的必备 用品。常减压蒸馏装置是石油加工的第一个装置，也称炼油厂的龙头装置，本课题 采用辽化原油，辽化原油属于低硫环烷中间基原油，根据原油评价数据，确定此原 油加工方案为燃料-化工方案。主要产品汽油，煤油，轻柴油，苯，二甲苯，甲苯， 乙烯，丁二烯等产品。并以 500 万吨/年的加工量，作原油蒸馏塔的工艺设计。采用 浮阀塔板，生产出汽油、煤油、柴油等馏分油。根据已知的原油数量来确定常压塔 的工艺设计，选择回流方式，蒸汽用量，核算各侧线抽出的温度和流量，作出气液 相负荷图，确定塔高，塔径及主要塔板的气液负荷图 。 关键词：原油加工，原油蒸馏塔，工艺设计 1 原油加工方案的确定及百万吨级/年原油蒸馏塔的设计 Abstrack Petroleum is essential material that national important energy material that group leader, is a citizen to live, often the decompression distils the device is a petroleum factory equip, this lesson an adoption turn the crude oil, the turn the crude oil belong to, according to crude oil evaluation data, certain this crude oil processes project as the fuel- chemical engineering project. main product gasoline, kerosene, light diesel, benzene, xylene, methyl benzene, ethylene product. and with 5,000,000 tons/ years process the deal, making the technological design that crude oil distil the tower. the adoption floats the valve tower the plank, producing a gasoline, kerosene, dieselcent oil. according to the crude oil quantity that have known to certain the technological design that often press the tower, choice reflux method, steam dosage, check the temperature that each side line draw out with the discharge, make a spirit the liquid to carries mutually diagram, the certain tower is high, tower path and main tower knothole spirit the liquid carries diagram. Key phrase:crude oil processes,crude distilation, technological design 2 原油加工方案的确定及百万吨级/年原油蒸馏塔的设计 目 录 第 1 章. 前 言………………………………………………………………………………..1 第 2 章 原油加工方案的确定………………………………………………………………2 2.1 原油评价……………………………………………………………………….2
