PSA控制说明资料

甲醇裂解制氢装置掌握操作甲醇进料流量体掌握方式如下：通过液位变送器LT2101监测原料缓冲罐V2101LV2101掌握酸性水进料，此时引起酸性水流量计FT2102FT2102跟FT2101FV2101。以此来掌握甲醇和酸性水的进料配比。TT2105TV2105aTV2105b联合掌握。PID掌握计量泵的电机转速，以此来掌握流量。V2102LT2102LV2102PID联合掌握。PSA产品出口总管上的压力变组成正常生产调整回路。同时设置超压放空PV2204B用于非正常生产和超压时的放空。〔PT2203压力上升段〕的工作段，在此工作段内，阀门开度为操作工设定的最小开度。其次个工作段对应于两次顺放段之间的时间段〔即PT2203压力下降段，在此时间段内，承受自适应调整方式，掌握回路承受PID随动掌握，其给定值由程序内部给定；该给定值为变量，变量的起点为前0.05Mpa左右，在其次段内变量的变化应当是匀速的。为到达这一目的，在“调整掌握组”画面中设定有两个分阶段的降压目标值。逆放气压力记录指示调整：本调整回路由安装于解吸气缓冲罐进口总管上的放过程产生的噪音。该调整回路的工作状态将影响装置解吸气的稳定和再生效果。在“调整掌握组”画面中确定下限开度和最终降压压力点的原则是：使吸附塔的逆放过程能实现匀速下降，且在逆放完毕时，吸附塔的压力恰好降到缓冲罐压力。这样才能保证解吸气的平稳。的压力变送器PT2205PV2205PT2206V2023PT2205PV2205PIC2205，该调整回路为单回路PIDPT2206PV2205PIC2206，PIDSPPT2206均值已经由软件自动计算出来，偏差值可在操作画面生给定，一般设为0～0.002MPaV2204PV2206PIC2205PIC2206值。解吸气缓冲罐超压放空调整:本调整回路由解析气出口总管上的压力变送器PT2206PV22060.001～0.06MPa。V2204PT2206产品气升压调整：本调整回路由吸附塔的压力变送器PT2202A～H和调整阀FRPIDSP为变量，变量的起点为开头升压时刻的吸附塔压力测量值，变量的终止点为SPI/O0213－1TIB21010213－1TIB2101AI(HART)2-00/051TIB2102AI(HART)1TIB2103AI(HART)1TIB2104AI(HART)YES1TIB2105AI(HART)YES1TOB2105AAO(HART)YES1TOB2105bAO(HART)1TIB2106AI(HART)1TIB2109AI(HART)1TIB2110AI(HART)1TIB2111AI(HART)1TIB2112AI(HART)1PIB2101AI(HART)YES1FIB2101AI(HART)YES1FOB2101AO(HART)YES1FIB2102AI(HART)YES1FIB2103AI(HART)YES1FOB2103AAO(HART)TT2101TT2102TT2103TT2104TT2105
