Comparison of the Life Cycle Cost of Carbon Steel, Duplex Stainless Steels, Super Austenitic, and Nickel-Based Alloys for Crude Unit Overheard Condensers

A refinery in the U.S. Gulf Coast had been using carbon steel tubes in two crude unit overhead condensers that suffered severe corrosion leading to premature failure after just 6 months in service. The metallurgy of the tube bundles was later upgraded to super duplex, UNS S32750, and hyper duplex stainless steel (DSS), S32707, which extended the service life to 12 months and two years, respectively. Failure analysis of the DSS indicated that the corrosion started as under-deposit corrosion. Selective corrosion occurred, where the ferrite phase suffered a preferential corrosion attack. Super Austenitic Alloy 35, UNS N08935, was recommended as an economical alternative to nickel Alloys 625 (UNS N0625 and C-276 (UNS N10276). Material selection and life-cycle cost analysis helped the end user select the super austenitic Alloy as the material of choice for the upgrade. The bundles have been in service for more than two years. This paper evaluates the materials selection process, fabrication cost, and life cycle cost analysis of the different Alloys used in these bundles since the first carbon steel upgrade through the present time.

Oil & Gas flowlines are paramount for safe and reliable production of hydrocarbons, ensuring their integrity is one of the key tasks for all operators. Petroleum Development of Oman (PDO) manages around 11,000 Km of flowlines and connects to production stations more than 400 wells across more than 50 fields every year. Applications for these flowlines vary from the traditional Oil & Gas transmission to other applications such as water injection, polymer flood and steam injection. All these diverse applications involve multiple operation environments ranging from benign fields with low CO2 < 0.5 mole% and minimum H2S to very aggressive environments with CO2 and H2S concentrations well above 10 mole%, combined with a wide range of salinities and water cuts, with chlorides concentrations ranging from 5,000 to 200,000 ppm and water cuts from almost nil to more than 95%. The challenges encountered in safe and economic development of these assets across such a wide range of conditions are numerous; therefore, the material selection and designed methods to manage flowlines integrity are complex with no single solution approach to address the myriad of different conditions. This paper present two cases of metallic and non-metallic materials installed in PDO flowlines showing their historical field performance and discusses the strategy adopted for the material selection of flowlines.

New inventions imply that these also should be implemented into relevant standards. Sometimes also minor modifications in the standard setup of the existing procedures are needed. For duplex stainless steels one of the most important aspects is if a correct final solution annealing has been performed giving the material proper properties.

Proposed Inclusion of UNS S82031 Into ASTM A1084

For new products there are always a need to include them in relevant standards. One of the major areas of standards are the ones verifying that the final solution annealing has been adequate not creating detrimental levels of precipitates. For duplex stainless steels the ASTM A923 and ASTM A1084 serve well for this purpose. The relatively new duplex steel UNS S82031 should be fitted in either of the two standards. It has been shown earlier that ASTM A1084, intended for leaner duplex steels, which does not precipitate intermetallic phases, fits better as these do not precipitate easily in UNS S82031. A modified, somewhat more aggressive, test solution for method C has also been evaluated and is proposed as a more relevant solution for the inclusion of UNS S82031 and possibly also other mid-range duplexes into ASTM A1084.
