NACE/ISO was released in 2009, but even after so much time has passed, there are still many customers who still use the 2002 version of the standard and may not understand the differences between the MR0175 2002 version and the 2009 NACE/ISO standard. Hydrogen sulfide (H2S) in process media presents significant risks to hydrocarbon facilities in terms of cost, equipment damage, and harm to personnel (Figure 2). Gold is a precious metal. Hard Water In other cases, the metal is precious because it is valued for other uses and is rare. The NACE MR0175/ISO 15156 standard is divided into three parts: Products or parts which are in contact with the process fluid meeting the criteria detailed in the standard.

NACE compliance is needed in applications where the risks of corrosion are high as these conditions can lead to material failure and could pose a risk to the public, personnel, and equipment. There are no overarching compliant materials for NACE/ISO because the process conditions always matter. The manufacturer or vendor, on the other hand, is responsible for making sure the users chosen material meets the metallurgical and manufacturing requirements and complies with any applicable testing requirements, and for complying with marking and documentation requirements. Courtesy: Emerson. The gas reserves in the Middle East, for example, are estimated to be about 60% sour. A 4 parts per million (PPM) concentration of hydrogen sulfide in air under standard temperature and pressure is often referred to as sour, and crude oil with more than 0.5% sulfur is called sour crude.
