Are compressor stations loud?
Are compressor stations loud?
Richard Wheatley, a spokesman for Kinder Morgan, TGP’s parent company, told The Recorder that compressor stations comply with federal noise regulations, with a maximum day-night weighted average of 55 decibels — about as loud as a conversation or an air conditioner.
What is the purpose of a compressor station?
Compressor stations are large industrial facilities that maintain the flow and pressure of natural gas by receiving gas from the pipeline, re-pressurizing it, and sending it back into the pipeline system. (Pump stations do the same thing for oil.)
What is a compressor station blowdown?
Description. When compressor stations are taken offline for maintenance or the system shuts down, the gas within the compressors and associated piping is either manually or automatically vented to the atmosphere (i.e., blowdown).
Do natural gas pipelines make noise?
Gas pipelines create a phenomenon of low and extra-low frequency soundwaves that occur in the communities they transverse caused by the operations of high pressure natural gas transmission systems. Hum is a persistent and invasive low frequency humming, rumbling, or droning noise not audible to all people.
How loud is a natural gas compressor station?
Although the noise level generated by a compressor station can be brief and abrupt, its startling effect can be annoying. The noise level near a compressor station can be up to 100 decibels whereas the usual nighttime noise level in many rural areas is around 35 decibels.
Is it safe to live near a compressor station?
3 The specific volatile organic compounds (VOCs) that are emitted by compressor stations have been associated with several serious health problems, including cancers, respiratory and cardiovascular illness, and birth defects4. The health complaints of residents near these facilities have been consistent.
How often do compression stations leak gas?
Standard practice is to blow down or vent the high pressure gas left in the compressor when it is taken off-line. While the compressor is depressurized, leakage can continue from the unit isolation valves, which are estimated to leak at an average rate of 1.4 Mcf/hour.
Why is my gas line so loud?
Air that’s become trapped in the line can generate a loud humming sound as gas moves around it to get to your appliances. It’s not dangerous but it is annoying. If you only hear humming around the gas regulator for your tank, it’s likely that the diaphragm being used is generating the noise.
Is it safe to live near a gas power plant?
Gas drilling and fracking release toxic pollution. Benzene exposure has killed oil and gas workers. Families living near oil and gas developments are reporting cardiovascular and respiratory illnesses including asthma, autoimmune diseases, liver failure and cancer.
How does a natural gas compressor station 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.
Should I be able to hear my gas meter?
We’ve received some customer questions about the hissing noise they should be listening for to spot a gas leak. Note that gas meters do make noise as part of their normal operation. More gas escaping natural gas piping or metering, either inside or outside your home.
What should be on the P&ID of a compressor?
Compressor aftercoolers are generally air coolers and the related fan, motor etc. should be clearly indicated on the P&ID. If cooling water is used, proper symbol for a heat exchanger should be used. Inlet, outlet lines for each equipment, anti-surge line, drain/vent lines, line to the relief valve etc. are the next to be drawn up.
What is a compcompressor station?
Compressor stations are an integral part of the natural gas pipeline network that moves natural gas from individual producing well sites to end users. Figure 1.

How to select the proper centrifugal compressor symbol?
Proper centrifugal compressor symbol should be selected first, as shown in figure-1. Normally, a centrifugal compressor is accompanied by a Knock Out Drum (KOD) at the compressor suction and an aftercooler at the compressor discharge, as per a typical compressor PFD.
When were the new compressor stations added to the air conditioning system?
In the 1989-91 period, three new compressor stations were added to increase capacity and a ninth station was added in 1997. Instead of using noise-path-treatment mufflers to reduce existing noise, it was decided to use noise-source-treatment technology to prevent noise creation in the first place.
