最近再用aspen对煤气化进行一些模拟,发现一些自己解决不了的问题,希望高人解答。
1、在定义煤的时候使用的是hcoalgen模块,但是后面的数字我看有人用的是6111,有的人是1111不知道这个代表什么意思呢?
2、模拟的煤的热解时,我使用的是RYIELD,但是结果不尽人意。警告如下:
* WARNING IN PHYSICAL PROPERTY SYSTEM
PARAMETER PC/ELEMENT 1 (DATA SET 1)
UPPER BOUND VIOLATED FOR COMPONENT C
VALUE = 0.22300E+09, UPPER BOUND = 0.10000E+09
* WARNING IN PHYSICAL PROPERTY SYSTEM
PARAMETER FREEZEPT/ELEMENT 1 (DATA SET 1)
UPPER BOUND VIOLATED FOR COMPONENT C
VALUE = 4300.0 , UPPER BOUND = 4000.0
Flowsheet Analysis :

出来的结果中的c明显的少了。不知道错在哪里。求高人指点。
添加失败的结果文件。求指点。
