No he didn’t, it sounds like they just aren’t purging the lines after use. That might be a product quality issue not a safety issue. I just wanted to make sure he understands that clearing the line with air is a bad idea. Maybe he can clarify the situation that is why I said if you are using air to clear the lines.

Therein lies the confusion. Not sure we know what we’re doing , why we’re doing it or the dangers associated with the how we’re doing it

Ok I gotcha.

They are transferring flammable product via pipeline into tanks at his facility. Also, the plant nitrogen is down. His question is, is that a safety violation to not have nitrogen available in the plant during said transfer.
He needs to read his procedures.

We batch transfer product all the time with no N2 used or needed all the time. The only instances I can see where it could be needed is if it’s to pressurize the feed tank or to clear lines between transfers to avoid cross contamination.

If you need to blow the lines and/or need to pump out of the tank that’s it’s going to, assuming it’s blanketed, don’t do it without nitrogen.

Are you pumping from one tank to another? Without nitrogen, how will you avoid pulling air into the feed tank and creating a flammable vapor space?
Is the tank you're pumping to pressurized?
What liquid are you pumping?
I'm a Chem E with years of experience at commercial chemical facilities and maybe can be of help.

We’re gonna need an update here when you do this.

I'd be more concerned if he was transferring out of a tank and did not have nitrogen available to supply to the vapor space. I'm assuming they would use nitrogen if the material in the tank is flammable. I've seen tanks get sucked in from inadequate nitrogen supply and a failed emergency vacuum vent.

I worked in plants all my working career (34 years) and also paid Union dues for the first 23 years. I never saw anyone get their job back even after arbitration. All that did was prolong the process. I have seen it in both Union jobs and non Union jobs. If they want to get rid of you they will find a way

Does the tank in question have a N2 blanket? Does the tank vent to flare? Is the N2 used to keep tank pressure/temp maintained?
Tough to say without knowing unit specifics.

So to update, we have a hot shot delivering a compressor sometime arriving later tonight. As of now, I shut down the pipeline transfer to the tank farm until the N2 is up and running. Gonna eat, watch football.

Good to hear!

Consider using an inert gas generator to provide purge gas. Commonly used in marine transportation. Basically just hook up your diesel exhaust from your pickup and you are home free. They might even give you a cost reduction award

quote:so is your name Karen or you gonna explain what in the process of transferring in a closed system absolutely requires N2 to do it safely. Don’t be a bitch or don’t be a halfwit. Why exactly does it take N2 to do a transfer. I’ve been doing this shite for 25 years and maybe, just maybe, I’ve missed something

“Are you pumping from one tank to another? Without nitrogen, how will you avoid pulling air into the feed tank and creating a flammable vapor space?”
Ever heard of a fuel gas blanket? Tank level drops, controller opens, lets in fuel gas in to control tank pressure. Tank fills and vents to flare recovery. Absolutely zero issues give or take. Who TF are you people talking about shite you barely understand

We purge lines with N2. All flammable coatings and resins. How hard is that to explain? Boy, you have real class, asking and using those phrases. I simply asked the forum, especially those who work in a similar environment as mine, for some friendly advice. It was much appreciated. Boy, you must be the biggest douche in the break room and at the company Xmas party with that attitude. Again, thanks to those who respectfully responded.

I don’t deal in respectful, I deal in reality. Explain your process to a point that absolutely needing Nitrogen makes sense and I’ll relent. Other than than that, you need to find a new vocation.
