How to Save and Share a Tower Packing Preliminary Engineering Report
After completing a preliminary tower packing screening, the next practical question is often:
How do I save the result and send it to my engineer, supplier or purchasing team?
The DAIER Tower Packing Engineering Assistant allows users to generate a preliminary engineering result and then either:
copy the report;
print the result;
save the report as a PDF.
This makes the tool useful not only for preliminary screening, but also for organizing project communication before an RFQ or detailed engineering review.

Why Save the Engineering Report?
A tower packing project may involve several people:
process engineer;
mechanical engineer;
EPC contractor;
tower manufacturer;
purchasing department;
packing supplier;
end user.
If everyone works from different messages, spreadsheets or screenshots, important project information can easily become inconsistent.
A preliminary engineering report creates one common reference containing the available project data and screening result.
It can then be used for:
internal project discussion;
supplier review;
RFQ preparation;
replacement-project comparison;
packing quantity confirmation;
identifying missing information.
1. Generate the Preliminary Result First
Before saving a report, complete the available project inputs in the Engineering Assistant.
Typical information may include:
project application;
tower internal diameter;
packing bed height;
number of beds;
operating temperature;
operating pressure;
packing material direction;
corrosion severity;
fouling or solids tendency;
project priority;
selected catalog product or model;
confirmed bulk density, if available.
Then select:
Analyze Project
to generate the preliminary result.
Before sharing it, check that the input information is correct.
2. Check the Result Before Saving It
Do not treat report generation as an automatic final step.
Review the result first.
Check:
Tower Data
Is the internal diameter correct?
Is the packing bed height correct?
Is the number of beds correct?
Operating Conditions
Are temperature and pressure correct?
Is the process application correct?
Is fouling information accurate?
Packing Information
Is the correct material family selected?
Is the selected packing model correct?
Is bulk density a confirmed value rather than an assumption?
If the input is wrong, save a corrected report instead of circulating an incorrect version.

3. Use “Copy Report” for Fast Project Communication
The Copy Report function is useful when the result needs to be transferred quickly into another communication channel.
For example, the report can be copied into:
an email;
an internal project note;
an RFQ;
a technical discussion;
a quotation request.
This is useful when the recipient mainly needs the project information in text form.
A copied report can also be combined with additional project information such as:
drawings;
existing packing photographs;
process datasheets;
delivery destination;
requested quotation scope.
4. Use “Print / Save PDF” When a File Is Better
For more formal project communication, saving the preliminary report as a PDF may be more practical.
A PDF can be:
attached to an RFQ;
stored in a project folder;
sent to an EPC engineer;
reviewed internally;
compared with later revisions;
attached to supplier correspondence.
This is particularly useful when several people need to review the same version of the project data.
5. Use a Clear File Name
Do not save every report as:
report.pdf
A useful project filename should help identify:
project;
tower;
date or revision;
report purpose.
For example:
DAIER_Tower_Packing_Preliminary_Report_Scrubber_T101.pdf
or:
T101_Packing_Replacement_Preliminary_Review_RevA.pdf
For a revised project:
T101_Packing_Review_RevB.pdf
This makes it easier to distinguish old and new screening results.
6. Do Not Send Only the PDF Without Context
The preliminary report should normally be accompanied by a short explanation.
For example:
Attached is the preliminary tower packing screening report generated from the available project data. Please review the packing direction and advise if additional process information is required before final recommendation and quotation.
This tells the recipient what the report is intended to do.
It also avoids presenting the report as a final engineering approval.
7. What Should Be Attached with the Report?
The report may not contain every project document.
For a new tower project, useful supporting information may include:
process datasheet;
tower drawing;
gas and liquid data;
process medium information;
required performance.
For a replacement project, also consider attaching:
existing packing photographs;
old packing datasheet;
tower internal drawing;
support-grid photographs;
distributor photographs;
current operating problem;
existing pressure-drop information.
The report provides the screening framework.
The supporting documents provide the project evidence.
8. What Should Be Sent to a Packing Supplier?
If the report is being used for quotation, the supplier should understand what action is required.
For example:
Packing Already Specified
Ask for:
price;
quantity confirmation;
bulk density;
net weight;
lead time;
packing method;
technical datasheet.
Packing Requires Review
Ask for:
preliminary packing recommendation;
suitable material;
suitable size;
additional required process data;
quotation after technical confirmation.
Replacement Project
Ask for:
review of existing packing;
replacement direction;
compatibility with existing tower;
quantity;
support / hold-down requirements if applicable.

9. The Report Is a Preliminary Engineering Record
The report should be understood as a preliminary project record.
It can help document:
what information was available;
what packing direction was screened;
what assumptions were avoided;
what information is still missing;
what requires further engineering review.
This is valuable because tower packing projects often evolve.
A project may begin with:
Revision A
tower diameter known;
liquid flow missing;
packing family not fixed.
Later:
Revision B
liquid flow confirmed;
packing family narrowed;
specific catalog model compared.
Saving each meaningful revision creates a clear technical trail.
10. When Should You Generate a New Report?
Generate an updated report when important project information changes.
Examples include:
tower diameter changes;
packing bed height changes;
process flow changes;
operating temperature changes;
material changes;
packing size changes;
existing packing information becomes available;
project objective changes.
Do not continue circulating an older report when the engineering basis has changed.
11. Do Not Confuse Preliminary Report with Final Datasheet
A preliminary Engineering Assistant report is not the same as:
final product datasheet;
approved technical specification;
final hydraulic calculation;
final packing drawing;
final tower-internals drawing;
process guarantee.
These documents serve different purposes.
The Engineering Assistant report is designed to support the early screening and communication stage.
After the packing is confirmed, the project may still require product-specific technical documentation.
12. Do Not Use the Report as a Hydraulic Guarantee
A preliminary report should not automatically be interpreted as confirmation of:
exact pressure drop;
flooding velocity;
percentage of flooding;
HETP;
HTU/NTU;
guaranteed separation efficiency;
final tower capacity.
These items may require complete process data and detailed project-specific calculations.
The value of the report is that it helps identify when this deeper engineering work is required.
13. Existing Tower Projects Need Revision Control
Revision control becomes particularly useful during replacement projects.
For example:
Rev A
Existing packing identified.
Rev B
Tower dimensions confirmed.
Rev C
New process throughput confirmed.
Rev D
Replacement packing model selected.
Instead of relying on many separate emails, the project team can retain each report version as the technical basis develops.

14. Example Workflow
A practical workflow can be:
Step 1
Enter the available project data.
Step 2
Analyze the project.
Step 3
Review the preliminary result.
Step 4
Correct any input errors.
Step 5
Use Copy Report for quick communication.
or
Step 6
Use Print / Save PDF for a project file.
Step 7
Attach supporting drawings and process information.
Step 8
Send the package for:
internal review;
supplier review;
RFQ;
further engineering confirmation.
This converts a web-tool result into usable project documentation.
15. Example Supplier Submission Package
A simple tower packing review package may contain:
File 1
DAIER Preliminary Engineering Report
File 2
Tower Drawing
File 3
Process Datasheet
File 4
Existing Packing Photos(for replacement projects)
Email / RFQ
State:
project objective;
required quotation scope;
delivery destination;
technical questions.
This is much clearer than sending isolated screenshots or short messages without context.
16. What If Some Data Are Still Missing?
You can still save the report.
The important point is not to hide the missing information.
The report can be used to identify:
Confirmed
Not Available
To Be Confirmed
For example:
Tower ID: Confirmed
Packing Height: Confirmed
Gas Flow: Confirmed
Liquid Flow: Not Available
Packing Model: To Be Confirmed
Bulk Density: Not Confirmed
This gives the next engineer or supplier a clear picture of the current project stage.
17. Report First, Final Confirmation Second
The Engineering Assistant is most useful when it supports a structured workflow:
Project Data
↓
Preliminary Screening
↓
Engineering Report
↓
Internal / Supplier Review
↓
Missing Data Confirmation
↓
Packing Selection
↓
RFQ / Quotation
↓
Final Engineering Confirmation
The report is therefore a bridge between the online tool and the real project workflow.
