The project record lists three QTD2200/99.9 units with a combined design capacity of 6,600 Nm³/h for continuous high-flow, high-purity nitrogen.
01 / CONTEXT
The project record lists three QTD2200/99.9 units with a combined design capacity of 6,600 Nm³/h for continuous high-flow, high-purity nitrogen.
02 / PROBLEM
With three units, load sharing and retained capacity during maintenance depend on peak duration and backup planning. Total design capacity is not a measured continuous demand.
Parallel trains and maintenance
03 / ENGINEERING
These are engineering considerations for this configuration. Project documents confirm the delivered scope, control design, test conditions and interface responsibilities.
The available record supports the configuration summary; no shipment date, customer acceptance or measured operating result is added here.
04 / VALUE
For a similar duty, assess supply continuity, maintenance, gas quality and total cost separately. The economic model below illustrates a calculation; it does not prove this customer’s saving or payback.
This image explains equipment configuration and engineering processes; it is not a customer-site or acceptance record.
EQUIPMENT & DELIVERY
Assembly follows controlled drawings and the equipment list. Review pipe supports, service access, electrical connections and instrumentation. Agree inspection items, test conditions and documents before manufacture. This manufacturing illustration is not evidence of a passed FAT.

EQUIPMENT & DELIVERY
Purity, residual oxygen and dew point are different specifications. Define the analyte, sampling location and pressure basis before choosing instruments, alarms and off-spec handling. The illustration explains the arrangement and contains no test readings.
PROJECT RECORD
The record follows three evidence lines: configuration, manufacturing and integration, then installation and commissioning. Images come from existing equipment, integration or commissioning records; text is tied to the confirmed location, industry, model and quantity.
Engineering record
The image helps explain equipment and process interfaces. Confirm the delivered configuration, inspection and acceptance against the project’s controlled documents; a general equipment image does not supply missing project facts.

PROJECT DELIVERY
Technical boundaries, delivery responsibilities and acceptance criteria are defined early to prevent interface rework on site.
Confirm flow, purity, pressure, dew point, operating hours, peaks and current gas cost.
Define scope, select equipment, model energy use and support technical tender documents.
Confirm utilities, interfaces, controls, safety interlocks, civil works and piping.
Build to controlled drawings and inspect key components, assembly, leakage, electrical and performance.
Coordinate packing, transport, lifting, piping, power and site readiness.
Complete checks, integrated start-up, purity and flow verification, training and acceptance records.
Track operating data and maintenance, with one-year contractual warranty and remote support.
ECONOMICS
Model, quantity and design capacity come from the project record. The table uses only the provided RMB 0.35/m³ on-site cost and RMB 0.90–1.20/m³ delivered price to calculate an auditable annual cost spread.
| Delivered unit price | Annual delivered cost | Annual on-site cost | Annual cost spread |
|---|---|---|---|
| RMB 0.90 / m³ | RMB 33,264,000 | RMB 12,936,000 | RMB 20,328,000 |
| RMB 1.05 / m³Midpoint scenario | RMB 38,808,000 | RMB 12,936,000 | RMB 25,872,000 |
| RMB 1.20 / m³ | RMB 44,352,000 | RMB 12,936,000 | RMB 31,416,000 |
FORMULA
Contract value and actual customer gas bills are not public, so this page does not invent investment, payback or ROI. Provide total investment, local power price, operating hours and maintenance budget for a formal calculation.
Illustrative model: RMB 0.35/m³ and RMB 0.90–1.20/m³ are reference inputs, not this customer’s bills. Load and hours are assumptions. Identify energy and maintenance already included in the on-site rate before deducting additional costs. Use the same volume basis; overseas projects require local prices and currency.
