Selecting the proper gas blending machinery is a central decision that impacts the safety, efficiency, and profitability of your operation. With so many technical considerations to evaluate, it is hard to know where to start. This comprehensive guide boils down the five most important factors to compare and contrast before you purchase. We will also explain how Okay Energy‘s precision-built products excel in each category so you can invest with confidence and for the long term.
Factor 1: Accuracy and Blending Uniformity – The Non-Negotiable
Importance of blending uniformity
Accurate blending is important to ensure the stable performance of downstream equipment. Poorly mixed materials can lead to pressure imbalance or unsafe combustion conditions. Our Calorific Value Control System ensures ±1% accuracy and 99% blending uniformity as demonstrated through our work with Tsinghua University.
- Hydrogen volume fraction: adjustable 5%-50%
- Blending uniformity: 99%
- Accuracy: ±1%.
How Okay Energy achieves high precision
We integrate advanced PLC control systems into all of our skid-mounted units to monitor flow rates, pressure levels, and component ratios in real-time. Skid-mounted all-in-one system featuring: Filtering, Mixing chamber, Pressure regulator, Flow meter, Sensor network, PLC control system. By this automation, each batch or continuous flow has target specifications.
Tolerances and calibration standards
Our units meet strict calibration requirements at delivery. A case in point is metering equipment used on our skids, which offers ±0.5% accuracy for custody transfer-grade measurements. Precise control of natural gas flows with integral pressure regulation (±1% stability) and custody transfer metering (0.5% accuracy).
Factor 2: Gas Component Properties and Compatibility
Understanding of gas properties and behavior
All of these kinds of gas—whether hydrogen with low density or LPG with high calorific value—require tailored handling methodologies due to variations in pressure characteristics, volatility, and reactivity.
Compatibility with different kinds of gas
Okay Energy’s facilities are capable of matching a range of gases like LNG, LPG, hydrogen, air, nitrogen, coalbed methane (CBM), blast furnace gas (BFG), coke oven gas (COG), etc. The most suitable mixing device can be selected against multiple sources of gases and differing ratios.
Okay Energy’s adaptability to different gases
We have applied our Calorific Value Control System with excellent results to dynamic flow-proportional mixing in various media such as LPG-air mix for SNG production at Pake Steel Mill Company (6000Nm³/h) and natural-gas–coalbed methane mix at ChinaResource (CR) (13500Nm³/h).
- Product Name: Calorific value control system
- Application: Synthetic natural gas (SNG)
- Client: Pake Steel mill company.
Factor 3: Automation Level and Control Systems
Manual vs automated systems
Manual systems entail constant human monitoring, increasing the cost of labor and increasing the risk of operational errors. Automated systems like ours use sensor networks and PLCs to monitor in real-time.
Benefits of automation in terms of consistency and safety
Automation offers reliable performance under varying operating conditions and enhanced safety using emergency shut-off valves and fault diagnostics.
Control options provided by Okay Energy
All of our skids are equipped with PLC-based automation that can be monitored remotely/on-site using Mod bus-compatible instruments. This allows for easy integration into existing plant control systems.
Factor 4: Maintenance, Calibration, and Long-Term Support
Maintenance is easy with time.
Our modular skid designs feature fast-connect piping (DN50 flanges), which simplifies installation as well as routine maintenance operations. Fast-connect piping (DN50 flanges) is adjustable to user tolerances.
Frequency of calibration and methods
We recommend periodic recalibration on the basis of operating hours or regulation requirements using certified calibration gases and equipment provided during commissioning.
Long-term service from Okay Energy
Okay Energy Company possesses an after-sales service department of 20 staff with rich after-sales service experience for decades, offering timely technical service in domestic regions as well as Southeast Asia and Africa.
Factor 5: Reliability and Total Cost of Ownership
Investment in Equipment Fitted for Continuous Operation
Durability is a result of the quality of the material, solid engineering, and sufficient factory testing. Choosing a well-tested system minimizes downtime and unexpected repair costs.
Okay Energy Durability Commitment
Every unit is put through rigorous factory acceptance testing before shipment. Our single-package skid-mounted design offers:
- Quick Deployment: Shippable modules allow field assembly and immediate start-up.
- Proven Long-Term Performance: We design for 24/7 industrial applications, as demonstrated in high-flow service like our 150,000 Nm³/h Shanxi Gas Group plant.
