石油化工企业进行油品炼制过程中主要有两套生产装置,一套是制氢装置:就是利用甲烷和水蒸气在800度催化剂条件下产生氢气:CH4+H2O=H2+CO+CO2.再利用后续的中变反应器脱除CO,(CO+H2O=H2+CO2),最后经过PSA变压吸附系统脱除H2中的CO2,最后得到纯度比较高的H2(氢气),满足加氢装置的生产用氢气,第二套装置是利用合格的氢气与油品中的硫化物、氮化物、氧化物、烯烃(操作条件是催化剂、高温、高压7.5MPa、300度)发生反应,达到脱除硫、氧、氮,并使烯烃饱和的过程,生产出合格的成品油供用户使用(环保、发动机要求)。 Petrochemical enterprises in the process of oil refining, there are two main production facilities, one is the hydrogen plant: is the use of methane and steam at 800 degrees under the conditions of catalyst to produce hydrogen: CH4 + H2O = H2 + CO + CO2. (CO + H2O = H2 + CO2) is removed by the subsequent neutralization reactor, and finally CO2 is removed from the H2 by a PSA pressure swing adsorption system to finally obtain H2 (hydrogen) with relatively high purity, and the hydrogenation device Of the production of hydrogen, the second set of devices is the use of qualified hydrogen and oil in the sulfide, nitride, oxide, olefin (operating conditions are catalysts, high temperature, high pressure 7.5MPa, 300 degrees) reaction to reach the removal Sulfur, oxygen, nitrogen, and the process of olefin saturation, to produce qualified products for the user to use (environmental protection, engine requirements).
