巴陵石化炼油联合装置以105×104t/a MIP-CGP装置为核心,配套产品精制、气体分离及循环水、空压站等公用工程系统。该装置直接以200×104t/a常压装置的渣油为原料,具有多产高辛烷值汽油和气体烯烃的特点。针对重油催化装置高气体收率和大注汽量的工艺特点,从催化生焦理论入手,进一步分析了随着进料密度、残炭和重金属含量的增加,装置的能耗越显著,联合装置的用能优化越复杂。通过对再生器取热系统、烟气余热回收系统、蒸汽能量梯级利用、烟机系统、供风系统、加热炉燃烧器系统、高低温位热能回收以及循环水、酸性水、凝结水系统的用能分析及优化改造,充分综合利用了各类能源,减少了装置对水的消耗。炼油联合装置能耗由72.20kg标油/t原油降至61.74kg标油/t原油,吨原油取水由0.72t/t降至0.61t/t,吨原油排水由0.64t/t降至0.30t/t。
Baling Petrochemical Refinery combined with 105 × 104t / a MIP-CGP device as the core, supporting product refining, gas separation and circulating water, air compressor stations and other public works systems. The device directly to 200 × 104t / a residual pressure of atmospheric equipment as raw material, with high-yield gasoline and gas-phase olefin characteristics. Aiming at the technical characteristics of high gas yield and large amount of steam injection of heavy oil catalytic device, starting with the theory of catching coke, the energy consumption of the device is more obvious with the increase of feed density, carbon residue and heavy metal content. The more complex the energy optimization is. Through the regenerator heat removal system, flue gas heat recovery system, the use of steam energy cascade, hood system, air supply system, furnace burner system, high and low temperature heat recovery and circulating water, acid water, condensate system Can analyze and optimize the transformation, full use of various types of energy, reducing the consumption of water on the device. The energy consumption of the refinery unit decreased from 72.20 kg / t crude oil to 61.74 kg / t crude oil, while that of crude oil decreased from 0.72 t / t to 0.61 t / t and that of crude oil decreased from 0.64 t / t to 0.30 t / t.
