Sundyne has supplied integrally geared vertical compressors since delivering its first unit to Union Carbide in 1965, and the company has since built more than half a century of experience in compression technology. By adapting its established LMV integrally geared pump design for high-performance gas compression, Sundyne has installed thousands of units across demanding upstream, midstream and downstream oil and gas operations worldwide. Its centrifugal compressor line is designed for custom process duties, oil-free operation and long maintenance intervals.
Core technical advantages and design approach
Sundyne's centrifugal compressor range is built around custom engineering for specific process requirements. Each unit is configured to deliver smooth, pulsation-free and vibration-free operation, according to the company. In process gas service, the equipment is designed to provide an oil-free environment with zero emissions, meeting strict environmental and safety requirements.
To handle varied industrial conditions, the compressors are designed to comply with API 617 standards and NACE material specifications. The design target is a continuous operating period of five to seven years without major overhaul or costly maintenance, reducing lifecycle operating costs for operators.
Product line and specifications
Sundyne offers single-stage and multistage centrifugal compressor designs for applications ranging from fuel gas boosting to complex gas processing. The main models and performance parameters are summarized below.
| Model | Flow range (ACFM) | Maximum working pressure |
|---|---|---|
| LMC-311P and 311F | Up to 2,000 | 1,440 psia (100 bar) |
| LMC/BMC-313 | Up to 2,100 | 1,000 psia (70 bar) |
| LMC/BMC-317 | Up to 3,550 | 1,000 psia (70 bar) |
| BMC-34X (Type A) | Up to 3,550 | 1,600 psig (110 barg) |
| Pinnacle LF-2000 | Up to 10,000 | 4,000 psia (350 bar) |
| LF-2X80 | Up to 6,000 | 1,440 psi (100 Bara) |
The table reflects published maximum flow and pressure ranges for each model, with flow listed in ACFM and pressure in psia, psig or bar as applicable.
Balancing performance and efficiency
Sundyne gas compressors use precise performance-envelope design to target the best efficiency point (BEP) in each application, according to the company. The approach is intended to balance reliability with efficiency in complex gas duties.
Whether the requirement is a single-stage integrally geared design or an API 617-compatible multistage system, the company says the range is capable of meeting high industry standards. The specifications and design targets form part of a broad portfolio for gas processing applications.
