Referring back to Figure 10—1, remember that we have compared the actual gas compressor speed to the speed indicated by the curve that passes through point &#8220;A&#8221;. We calculated point &#8220;A&#8221; from the natural gas flow, and the observed suction and discharge pressure. We said that if the measured gas compressor speed exceeded the speed [...]]]></description>

One way of looking at a gas turbine centrifugal compressor is that the combustion air compressor must pump sufficient air to support combustion across the turbine blades as needed to spin the gas compressor at its required speed. Any factors which reduce the flow delivered by the combustion air compressor will reduce horsepower available to [...]]]></description>

Gas turbines are limited, as are all rotating assemblies, by either speed or power. For an electric motor, the power limit is manifested by maximum amperage, (more precisely, the maximum permissible winding temperature). The situation with gas turbines is similar. The ultimate amount of power (i.e. work, horsepower), that can be developed by the turbine [...]]]></description>

		<description><![CDATA[A centrifugal compressor driven by a gas turbine at a pipeline booster station is moving 80 MMSCFD of natural gas. It used to move 95 MMSCFD. What&#8217;s wrong? As the troubleshooter, consider whether the problem is with the driver or the compressor. Actually, there are three primary components involved:
• The combustion air compressor.
• The turbine [...]]]></description>

		<description><![CDATA[While the majority of natural gas field and transmission compressors are reciprocating machines, a sizable minority are centrifugal compressors driven by gas turbines. Only on rare occasions can electric, steam or deisel oil drives compete with natural gas as compressor fuel in pipeline service.
A gas turbine works on the same principle as a jet engine. [...]]]></description>

		<description><![CDATA[A handy rule of thumb to retain for compression troubleshooting jobs is that the theoretical temperature increase of gas due to compression is linearly proportional to compression horsepower. An extremely useful application of this rule of thumb is the following approximation:

It is not too much to say that this relationship is the most important concept [...]]]></description>

• Set the compressor to run at a constant speed.

Inserting the data from the El Gringo operation in the above equation I found:

1. The gas velocity through the contactor tower must not be great enough to entrain glycol into the dried gas. Theoretically, the entrainment of glycol does not interfere with drying. In practice, the continuous loss of glycol will knock [...]]]></description>

		<description><![CDATA[Drying towers in natural gas service can become rapidly fouled with drilling mud or formation and frac sand. The sand appears in the wellhead gas when the rate of gas production becomes excessive, and the sand is thus sucked out of the formation and into the well&#8217;s tubing. Drilling mud is found in natural gas [...]]]></description>
