HAZOP Assignment for ChE 4284/5292
Individuals will perform a HAZOP on a single unit operation of a model power plant based off of the
National energy Technology Laboratory (NETL) Vol 1 of ‘Cost and Performance Baseline for Fossil Energy
Plants’. You can download the file from this link:

Each student will choose a specific unit of the plant from study area 1 – 7 (identified in red box and
labeled as Main Unit). Table shows the study area and the corresponding pages of the document that
are related to that unit. Perform a HAZOP of the unit, detailing possible deviations in normal operation
and what would be the predicted outcomes of the deviations. Present this information as a table.
Identify if the deviations cause issues with product quality (such as reduced energy production) or a
hazard (such as loss of containment of steam). You do not need to detail every possible deviation, but
should include enough details to address at least 4 deviation of each major inlet/outlet node. You should
be able to identify at least 2 nodes (CHE 5292 students, please select 3 nodes). Summarize the findings
of your HAZOP analysis and note which deviations you were not able to find corrective actions for (1-2
pages). Suggest a method used for investigating corrective actions.
Here is the content of the report: Cover page, abstract, introduction about the unit operation, HAZOP
table, discussions and recommendations, and references (IEEE style). Please use Times New Roman,
single space, 12 Font, 1 in margin.
If you do not understand the assigned units please contact the instructor. You do not have to read the
entire NETL report.

Alloy is a metal made by combining two or more metallic elements, especially to give greater strength or resistance to corrosion. They are homogeneous mixture of two or more substances. An example of an alloy is the tin in the mixture of copper and tin that makes bronze.

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 2021 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.
