DECON-X Vapor Phase Cleaning - Easy Calculation Guide
Quickly estimate how much DECON-X you need for refinery decontamination using our proven calculation method, backed by 20 years of experience.
Step 1: Calculate the Vessel Volume
Let's use an example of a crude atmospheric tower:
- Height: 30 meters
- Diameter: 7 meters
- Internal structure: 40 trays, all of a bubble-cap design
Use the formula to calculate tower volume (without taking account of the dished-ends):
V=pi x R2 x L
V=3.14 x (3.5)2 x 30=1,154m3
Step 2: Determine the DECON-X Requirement
We recommend 4 liters of DECON-X per cubic meter of column or vessel internal volume. Therefore, the volume of DECON-X required would be:
1,154 x 4=4,616 liters
Since 1 drum of DECON-X = 208 liters, the total drum requirement is:
4,616 / 208=22 drums
Step 3: Comparing to Liquid Circulation
If using a traditional liquid circulation method:
- Filling 20% of the column to cover the trays and provide a positive pump suction will require:
- 1,154 x 20%=230m3
- Using a 2% DECON-X concentration:
- 230 x 0.02=4.6m3 (or 22 drums of DECON-X)
Why Choose Vapor Phase?
- Cuts decontamination time by 2/3 compared to liquid circulation.
- No liquid disposal required, reducing environmental impact.
- More efficient and cost-effective, with faster equipment turnaround.
