Where's u tankers loading at this morning

I'm assuming that is what is going on the internal valve is not budging..... it got top loaded two days ago... temps have kinda been all over here with low as around 13. It just won't flow it's a no touch load for me so I'm not super familiar with it yet. Any thoughts lol?

 

Honestly, I didn't think those temps would have frozen the product.

 

That is what I thought as well but I did notice they loaded this from two separate rail cars....I'm not sure what temps they have been exposed to themselves.

Found some articles I've been reading on it I'm still not sure what is going on.

"4.3 Effect of Freezing Freezing of methacrylic acid should be avoided. Thawing of frozen methacrylic acid can be extremely hazardous. Methacrylic acid freezes at 15°C (59°F). As freezing occurs, the first crystals formed contain pure monomer with very little inhibitor; the inhibitor is concentrated in the liquid phase. When freezing occurs in bulk containers, the first crystals, low in inhibitor, will form along the outer wall of the container. The inhibitor will be concentrated at the center. Improper thawing may lead to pools of monomer containing low levels of inhibitor. This condition is made worse by repeated freeze/ thaw cycles if the methacrylic acid is not mixed well after each thawing. If possible, the acid should not be thawed by applying heat directly to the outside of the container because the potential of polymerization of the low-inhibited monomer along the walls is possible. The temperature of the acid should be maintained at 18-40°C (64-104°F). The ideal storage temperature is 20-25°C (68-77°F). Other temperature targets between 18-40°C (64-104°F) may be needed on a seasonal or situational basis. In the event freezing does occur, follow procedures in Section 6, Thawing of Frozen Methacrylic Acid."

According to this I'm right in the ideal range according to the gauge assuming that is accurate. This article I'm currently reading gives some advise which we have already tried. Gonna be interesting to see how tomorrow goes.

I don’t know if I want to do chemicals now

 

Chemicals aren't that bad overall in my green experience, you just gotta always respect what your doing and personally I treat every single load like it's methalethal kill you...... overall you just gotta kind of relax and just get the job done safe as you can. Only jobs that are somewhat of a pain is pump jobs but even that is not hard to do, it's just time consuming and you have to do things in order.

 

Yea, being safe is important.

 

I hauled that once. If I remember correctly, when it polymerizes it can become an explosion hazard, maybe only when it burns, but I think it is classified as both corrosive and flammable. Nasty stuff. Be safe.

 

Correct if polymerization starts it builds pressure then and can become extremely unstable. Not sure what they are doing with the load we got 30k pounds out of it yesterday but the last 11,880 pounds just kept stopping. Hate saying it this way but was told it's no longer my issue nor is it my fault lol....I'm glad to be done with it lol.

 

Did it freeze up again?

 

Not sure what is going on, according to the gauges on the trailer and at the customer the product is within the temp window... somewhat on the lower side but still acceptable. They said this just happens sometimes during the winter so idk. It's only my second time hauling this product and it's a full no touch load for us.
