How much does a natural gas compressor station cost?
How much does a natural gas compressor station cost?
A new compression station is a major investment, costing on average $2 million to be fully functional — not counting the maintenance and labor costs which will eventually come. Yet, on fuel savings alone, the conversion to electric compressors can have a payback period of one to three years.
What happens to natural gas at a compressor station?
Natural gas enters a compressor station through station yard piping and is passed through scrubbers and filters to extract any liquids and remove solids or other particulate matter that may be in the gas stream (Figure 1).
Why are compressor stations used on natural gas pipelines?
Compressor stations are above-ground facilities that are typically located every 50 to 100 miles along natural gas transmission pipelines. They compress natural gas to move it through the pipeline and ensure natural gas flows at sufficient volumes for reliable service at delivery points.
Are natural gas compressor stations safe?
Are natural gas compressor stations safe? Yes. Natural gas transmission compressor stations must be engineered, constructed, operated and maintained in accordance with Pipeline and Hazardous Materials Safety Administration safety standards.
How much does a gas compressor cost?
First, the cost of a compressor is roughly: U.S. $0.5–0.9 million/MW for the 5–15 MW range; $0.8–1.5 million/MW for the 1–5 MW range; and $1.3–4/W for units below 1 MW.
How does a natural gas compressor work?
A natural gas reciprocating compressor uses pistons and positive displacement to compress the gas. Gas enters the manifold, flows into the compression cylinder, then discharges at a higher pressure. The heating and cooling of the gas along with the compression makes more liquids fall out of the gas.
What is a natural gas take station?
When the natural gas in a transmission pipeline reaches a local gas utility, it normally passes through a “gate station.” Utilities frequently have gate stations receiving gas at many different locations and from several different pipelines.
How much natural gas can be released during a blowdown?
On average, a single blowdown will release approximately 15 thousand standard cubic feet (Mcf) of gas to the atmosphere.
What are gas air compressors used for?
An Example Gas Air Compressor
| Component | Purpose |
|---|---|
| Unloader | Decreases engine load, lowers sound levels, and reduces fuel use and engine load; set to open when the compressor develops the maximum regulated air pressure and delivers air pressure to the throttle control to reduce engine speed |
How much will your compressor installation cost?
The average home air conditioning compressor costs $1,200 to replace with a typical range anywhere from $800 to $2,800. Parts and labor each make up about 50% of the price. You’ll pay $400 to $1,600 for the parts alone. Labor runs $400 to $1,200 with most contractors billing $50 to $150 per hour.
Why are compressor stations important to the natural gas industry?
Compressor stations are an integral part of the natural gas pipeline network that moves natural gas from individual producing well sites to end users. As natural gas moves through a pipeline, distance, friction, and elevation differences slow the movement of the gas, and reduce pressure.
How are liquids captured in a natural gas compressor station?
In wet gas areas, or areas that produce natural gas liquids (NGLs), changes in pressure and temperature cause some of the liquids to drop out. The liquids that drop out are captured in tanks and trucked off site. The liquids captured are referred to as natural gasoline or drip gas, which is often used as a blend in motor gasoline.
Which is the largest source of noise in a compressor station?
The largest source of station noise is from the gas turbines used to power our gas compressors. These units are located within a sound proofed acoustical enclosure which is housed within compressor buildings, and the buildings are built to further dampen noise.
How are gas turbines at a compressor station controlled?
The gas turbines are powered by a portion of the natural gas that flows through the pipeline. Each turbine compressor unit is controlled by a state-of-the-art control system that monitors its operation, controls the interaction between it and the yard piping systems, and safety shuts it down if a fault condition exists 4.
