Core Technologies and Services:

1. Natural Gas Purification and Treatment

[1] Amine Sweetening: Utilizes mixed amine (MDEA) or proprietary amine solutions to efficiently remove acidic gases (H?S, CO?) from natural gas, meeting pipeline transportation or liquefaction requirements.

- Capacity: 1,000–500,000 m3/h

- Output Specifications: H?S<4 ppm, CO? <50 ppm  

- Adaptability: Tailored process combinations for gas sources with high/low CO? or impurities.

[2] TEG Dehydration Technology: Triethylene glycol (TEG) adsorption under high pressure and low temperature reduces water content in product gas to<7 lb/MMSCF. Intelligent simulation optimizes solvent consumption.

2. Natural Gas Liquefaction (LNG) & Light Hydrocarbon Recovery

[1] Mixed Refrigerant Cycle (MRC): Integrates pretreatment, cryogenic liquefaction (-162°C), and storage to produce high-purity LNG (H?S<3.5 mg/m3, H?O <1 ppm). Daily capacity: 10,000–5,000,000 m3.

[2] Light Hydrocarbon Recovery: Innovative processes (e.g., expansion refrigeration, GSP/DHX) achieve >95% C2 recovery rate, maximizing resource value.

3. Sulfur Recovery & Tail Gas Treatment

[1] Claus Process & Tail Gas Purification: Multi-stage Claus reactors or hydrogenation reabsorption recover sulfur (2–500 t/day) with 99.8% efficiency. Near-zero emissions, adaptable to acid gas containing NH?, HCN, etc. Co-generates high-pressure steam to reduce energy consumption.

4. Crude Oil Treatment & Produced Water Re-Injection

[1] Crude Stabilization: Process chain (three-phase separation → electrical dehydration → vacuum flashing) produces commercial crude with<0.5% water content.

[2] Produced Water Treatment:

- Efficient oil removal via hydrocyclones (80–90% efficiency), compact flotation units (CFU), and coalescence separation (CPI).

- Smart chemical dosing (reverse demulsifiers, desulfurizers) combined with walnut shell/dual-media filtration ensures reinjection compliance.

5. Digital Engineering & Lifecycle Management

[1] Smart Design Tools: ASPEN HYSYS, PDMS, and other software for process simulation, 3D plant design, and pipeline stress analysis.

[2] Modular Delivery: Skid-mounted and prefabricated units reduce project timelines by 40% and on-site risks.

Success Cases:

- Yadavaran Oil Field, Iran: CPI coalescers + walnut shell filtration achieved crude oil water content<0.5%.  

- Saudi Aramco CO? Dehydration Project: TEG technology reduced gas moisture to industry-leading levels.

- Liuhua 16-2 Oil Field, China: Hydrocyclone skids efficiently treated high-oil-content produced water.

- Liwan 3-1 Gas Field: CFU compact flotation units improved wastewater treatment efficiency, reducing chemical usage by 50%.
