Debunking Common Misconceptions
Misconception 1: Manual Tank Cleaning Is Cheap
Only the single cleaning fee is counted, ignoring hazardous waste disposal, shutdown losses, oil discount and personnel safety rectification costs. Hidden losses over a cycle can reach hundreds of thousands to millions.
Misconception 2: Thin Sediment Loss Is Negligible
The thin bottom layer has extremely high oil content, accumulating year after year and permanently occupying rated tank volume. Effective storage keeps shrinking, and the inability to stock up in peak season directly reduces revenue.
Misconception 3: Tank-Bottom Loss Has Little Economic Value
Sediment keeps accumulating and never disappears; every extra year of storage adds another year of loss, compounding over the long term. A one-time investment of tens of thousands in equipment recovers tank-bottom losses continuously for 20 years, eliminating frequent cleaning.
Single-Cycle Cost Comparison
| Industry | Single-Cycle Manual Cleaning Loss | One-Time Jet Equipment Investment | Single-Cycle Net Savings | Payback Period |
|---|---|---|---|---|
| Petrochemical 10000m³ crude tank | RMB 870,000 | RMB 78,000 | RMB 792,000 | 4 months |
| Grain & oil 5000m³ crude oil tank | RMB 420,000 | RMB 38,000 | RMB 382,000 | 3 months |
| Metallurgy large alumina digestion tank | RMB 1,300,000 | RMB 50,000 | RMB 1,250,000 | 1.5 months |
Core investment logic: tank infrastructure often costs tens or hundreds of millions, while the entire jet equipment costs only tens of thousands — a negligible share that continuously reduces hidden losses in the millions.
