SYNTHETIC RUBBER AND HIGH SULFUR NATURAL GAS-NEED WORK HELP

[Pablo]

Chemists, et al;

Need quick help.

We have some NG low pressure regulators (real thin synthetic rubber diaphragms) failing in certain applications. Our field guys claim they are high sulfur NG places. We are having the gas analyzed.

Does anyone know compatability???

Here's a pretty good table to check for compatibility.

You need to know what sulfur compound is in the gas. Sulfur dioxide, hydrogen sulfide etc.

Wow - great info. Nice online chart. Thanks Mr. Kule

I'll see what the analysis says- and if the specific S compound is not called out I'll go deeper.
