This article is based on a white paper written by John Carissimi and Jeremy Payne in 2015 and rewritten on May 6, 2024. Sour gas and crude oil operations involve harsh conditions with a high risk of corrosion. Metals and alloys used in environments with hydrogen sulfide (H2S) are especially prone to corrosion and stress cracking, which can lead to material failure and dangerous fluid leaks in your system. To enhance safety and prevent equipment failures, the National Association of Corrosion Engineers (NACE) established control standards for any instrumentation used in these types of applications. As the Product Marketing Leader for process gauges at Ashcroft, a global leader in pressure and temperature instrumentation, I have spent the past 15 years answering questions and guiding customers on the importance of ensuring compatibility between your instruments and process media. In this article, you will get an overview of the NACE standards that specifically address corrosion that can occur with exposure to sour gas or sour crude. You will also learn what to look for when selecting pressure and temperature instruments for your sour gas and crude applications. When you are done reading, you will be able to access additional resources to help make informed decisions about selecting instrumentation for corrosive operations.
