EPC Air Separation Unit Project

●Customized Solution Design to Adapt to Diverse Needs

Experienced engineers will develop customized solutions based on the customer's production capacity (500-10,000 Nm³/h), gas purity (O₂ ≥ 99.6%, N₂ ≥ 99.999%, Ar ≥ 99.999%), scenario, and site:

Optimized equipment layout reduces floor space by 30%;

Designed low-consumption routes, incorporating local energy resources, reduce unit gas consumption by 15%-20%;

Reserved expansion capabilities to accommodate growth over the next 5-10 years.
 

●Controllable Full-Lifecycle Costs, Avoiding Additional Expenses

Using a "fixed-price + transparent procurement" approach, all costs are clearly defined upfront, avoiding later item additions.

Group procurement reduces the procurement cost of core equipment by 10%-15% compared to in-house procurement.

Optimized construction schedule, shortening the project by 20% compared to traditional methods, enabling earlier commissioning and generating additional revenue.

●A professional team leads the entire process, mitigating project risks.
The project team includes professionals in process engineering, procurement, construction, and safety, who oversee key milestones throughout the entire process:
Procurement: Supplier qualification review and on-site inspection, 100% factory inspection of core components;
Construction: Implementation of ISO 9001 and safety standards, 100% non-destructive testing of key processes;
Commissioning: Experienced air separation engineers participate to ensure a successful first-time system startup and 100% compliance with purity and production capacity standards.

      
 

A 6,000 Nm³/h air separation project at a large steel company:

A customized "oxygen + nitrogen" dual-product system was developed to meet the needs of blast furnace ironmaking. The project went from contract signing to commissioning in just 10 months. Oxygen purity remains stable at 99.8%, saving approximately 2 million yuan in annual energy costs.

A 10,000 Nm³/h air separation project at a chemical park:
Utilizing an "oxygen, nitrogen, and argon co-generation" process, it simultaneously supplies the gas needs of three companies. Centralized construction reduced investment costs per plant by 30%. The system has operated for five years without major failures, achieving an average load factor of over 95%.

1. Can EPC air separation projects be customized? Will subsequent expansion require reconstruction?

Fully customizable, it will be combined with optimized site layout (saving 30% in land). Expansion ports are reserved, allowing for later addition of core components without reconstruction, adapting to 5-10 years of growth.

2. Is the EPC model cost-transparent? How much savings can it offer compared to contracting with multiple parties?

Cost transparency, fixed price with no additional costs. Core equipment procurement saves 10%-15%, construction time is shortened by 20%, and early commissioning brings additional benefits, resulting in significant overall advantages.

3. How long does it take from project contract signing to commissioning? What are the differences in lead times for different capacity levels?

The total lead time is 8-17 months. 500-3000 Nm³/h: 9-13 months; 3000-10000 Nm³/h: 13-17 months , with dedicated manager-controlled milestones.

4. How is construction quality and safety ensured? How is responsibility allocated in the event of problems?

Construction will comply with ISO 9001, with 100% non-destructive testing of key processes. Equipment procurement is subject to strict qualification review, and core components are 100% inspected. We will assume full responsibility for equipment quality or construction errors, and will provide free replacement and rework, along with compensation.

5. What support is provided for post-delivery operations, maintenance, and spare parts? How long does it take to recover from a fault?​
Core equipment comes with a 2-year warranty, while the entire system is covered by a 1-year warranty. We offer 24/7 remote diagnostics and 24-48 hour on-site service. Spare parts are available from five warehouses, delivered within 48 hours, and fault recovery takes 1-3 days.
