it is known that water and other liquid in fuel gas (Natural gas) can be removed by various equipments like knock-out drum, filters, etc.

But is there any method to remove metals that are present in the gas before being used for combustion.

Any suggestions/ reply in this regards will be]]></description><pubDate>Thu, 23 May 2013 06:26:59 EST</pubDate><guid><![CDATA[http://cr4.globalspec.com/thread/84803]]></guid><dc:creator>varunpassi</dc:creator><dc:subject>Mechanical Engineering</dc:subject></item><item><title><![CDATA[Would You Like to Do a Short Interview?]]></title><link><![CDATA[http://cr4.globalspec.com/thread/84796/Would-You-Like-to-Do-a-Short-Interview?from_rss=1]]></link><description><![CDATA[I have been interested in exploring a career in Mechanical engineering. specifically in design Bicycles.

i want to calculate pressure drop in compressed air line using formula

there are same formula have different substitutes which is true please help me to select accurate one

the formulas are
