New double septum acoustical covers

We’ve just installed more covers on vessels-V 31,32,33,34. With this latest addition, we’ve spent over $250,000 on sound attenuation so far.

We’ve just received the acoustical cover for V-1580. We’re very slowly blanketing our noisy vessels in the processing plant with thick acoustical covers, trying to ensure that none of our neighbors are inconvenienced at all by any of the sounds made while we’re processing our green gas. As always, feel free to drop us a line and let us know how we’re doing!

The custom double-walled acoustical blanket arrived and we installed it the very next day. Already we can hear a noticeable reduction in sound here at the plant. Hope it’s noticeable further away, too.

Last week we retained Omega Squared consulting to do another vibration and noise evaluation on our tank farm vessels. The results point to one specific vessel on that emits a low ‘groan’ whenever gas is rushing into or out of the tank. This causes a bit of resonation and is the source of the particular sound. We’ve ordered a custom fitted ‘double septum’ blanket to cover the entire vessel. This blanket is also specifically designed to absorb the exact frequency that the vessel emits. We’ll update again when we’ve got it installed.

Though we’ve had access to the detailed results from the last sound study for a few weeks now, various operational issues at the plant have prohibited us from successfully diagnosing more specific sources. We simply haven’t had the plant online consistently for long enough to be able to monitor specific components during normal operations. But now that we’ve run steadily for a few days, we’ve been able to glean some more information. What we’ve found out is that there are unfortunately a handful of distinct sounds which the plant will make when operating normally. The good news is that most of these noises are produced by a handful of the hundreds of valves which are continuously adjusting and resetting in the normal operation of the plant. We’ve measured up the offending components and ordered custom ‘blankets’ to surround them and absorb most of the sound. Will update when they’ve arrived and we’ve installed them.
