DescriptionBLEVE Assignment
Perform a BLEVE consequence model of SPLITTER TOWER of the ISOM unit of Texas City Refinery by
using ALOHA software. Prepare a 2-3 page report (Font: Times New Roman, size: 12, margin: 1 inch)
including these sections: (1) Problem definition; (2) Methodology/calculations of BLEVE; (3) Explain your
result; (4) Conclusions and recommendations; and (5) References. Please add the ALOHA report as
appendix to the report (does not count as page limit of the report).
Assume the ISOM unit contains pure HEXANE and your preferred location in Florida (anywhere but avoid
the national parks). Use a random time of the day and date of 2023 for this exercise. Logical sequence of
this assignment is following:
Step 1: Watch the CSB video and list the information you will be using for the model. Also, watch the
lecture very carefully. Download ALOHA software and practice the class problem.

Step 2: If any of the required data is missing in the video please make logical assumptions (with
reference if possible).
Step 3: Determine the BLEVE threat zone.
Step 4: Generate the report and attached it with the homework assignment.
Step 5: Place the ALOHA generated threat zone in google map and see how it affects the nearby
community. Save this file and attached with the assignment.
Step 6: Discuss your opinion based on the findings in tasks 3 and 5.
