I was wondering what the purpose of this piping connection is. My initial guess is that it's a <b>venturi connection</b>, since it needs to drop the pressure while maintaining the velocity to reach the top. (I'm not sure if there's a standard regarding pressure in top foam pourers.) However, that piping connection is closer to the manifold than the tank itself, which makes me think that my initial assumption is wrong.</p>]]></description> <pubDate>Wed, 03 Sep 2025 07:49:57 +0000</pubDate> <guid isPermaLink="false">https://www.cheresources.com/invision/topic/32693-top-foam-pourer-line-reducer-connections/</guid> </item> <item> <title>Igv Control For Compressor</title> <link>https://www.cheresources.com/invision/topic/32692-igv-control-for-compressor/</link> <description><![CDATA[Hello everyone,<br><br>I’m working on a dynamic centrifugal compressor simulation where the capacity is controlled by inlet guide vanes (IGVs). I’d like to clarify how the IGVs should behave during different shutdown scenarios:<br><br>Emergency Shutdown (ESD): My understanding is that IGV position doesn’t change during an ESD, so the simulation should be run with the normal operating IGV position.<br><br>Normal Shutdown: In this case, the IGVs can be driven to their minimum position as part of the turndown sequence.<br><br><br>Since I’m new to this type of control, I’d really appreciate any insights or confirmation from those who have dealt with IGV-controlled compressors.<br><br>Thanks in advance!]]></description> <pubDate>Sat, 30 Aug 2025 06:21:45 +0000</pubDate> <guid isPermaLink="false">https://www.cheresources.com/invision/topic/32692-igv-control-for-compressor/</guid> </item> <item> <title>Radar Level Instrument</title> <link>https://www.cheresources.com/invision/topic/32691-radar-level-instrument/</link> <description>Hello, please does a radar level instrument installed on a storage tank require an isolation valve ?</description> <pubDate>Sun, 24 Aug 2025 20:06:34 +0000</pubDate> <guid isPermaLink="false">https://www.cheresources.com/invision/topic/32691-radar-level-instrument/</guid> </item> <item> <title>Centrifugal Compressor Recycle</title> <link>https://www.cheresources.com/invision/topic/32688-centrifugal-compressor-recycle/</link> <description><![CDATA[Hello, I'm doing a reverse engineering study for a BOG recovery system that has a centrifugal compressor and an LNG quench system to maintain compressor suction temperature.

For SMR plant, if the reform steam carryover liquid drop, can this cause a reformer tube hot band problem? for example: Steam drum demister Or sour water stripping tower demister degradation.</p><p> </p><p>As I mentioned in another post, there was steam carrying liquid from the sour water stripping tower several times. <a href='https://www.cheresources.com/invision/topic/32200-steam-carrying-liquid-from-the-sour-water-stripping-tower/' class='bbc_url' title=''>https://www.cheresources.com/invision/topic/32200-steam-carrying-liquid-from-the-sour-water-stripping-tower/</a></p><p> </p><p>Several temperature thermocouples along the line captured the temperature drop, The temperature at the end is above the saturation temperature, but I suspect there is a measurement blind spot.
