Hi Everybody!

 

 Me and my friend are new to the topic and we have a limited knowledge of simulating amine plants.

 

Our objective is removal CO2 and H2S with secundary amine (DEA).

 

our question is:

 

In simulator aspen plus there are radfrac block, but when we get started to simulation the error message appear:

 

***SEVERE ERROR

   INSUFFICIENT STORAGE ALLOCATION FOR DECOMPOSITION.

   USE **STOR-FACTOR** GREATER THAN  10.00      IN PARAM SENTENCE.

   TRY INCREMENTS OF 0.5.

 

***SEVERE ERROR

   CMBAL CALCULATIONS FAILURE: RERUN WITH CHANGES SUGGESTED

   IF THERE ARE ANY.

 

***SEVERE ERROR

   INSUFFICIENT STORAGE ALLOCATION FOR DECOMPOSITION.

   USE **STOR-FACTOR** GREATER THAN  10.00      IN PARAM SENTENCE.

   TRY INCREMENTS OF 0.5.

 

*  WARNING

   REST OF BLOCK BYPASSED DUE TO SEVERE ERROR.

 

 

 

And we don't know, how to fix them.

 

Someone had the same problem, could please, help us?

 

 

our specification to radfrac:

 11 stages

buttom pressure 10 bar

top pressure 11 bar

colunm with pall ring packing
