RESEARCH-GRADE DUAL AUTOCLAVE SYSTEM
Research Project:
Physical and corrosion properties of pipeline, downhole and refinery steels and alloys
Optimization of anti-corrosion chemicals inhibitor formulations and dosage rates
Cost Savings Relation of Laboratory Test Results to Field Operations:
Materials of Construction
Material’s selection decision can be greatly improved by evaluating the material’s performance at high temperature and high pressure in a laboratory autoclave. These systems are very versatile, permitting short term tests for inhibitor screening, medium term electrochemical evaluations, and very long-term exposures. From these results, informed decisions can be made to optimize cost vs. performance of materials used in pipelines, valves, fittings, pumps, pressure vessels, and heat exchangers.
Corrosion Inhibitors
Inhibitor performance can be evaluated using multiple techniques in autoclave systems. Shear stress measurements using jet impingement or rotating cylinder tests can accurately define inhibitor performance, permitting selection of proper formulations.
PURPOSE OF RESEARCH
This dual autoclave system is necessary to accelerate tests screening results and support the I0 Dynamic Multiphase Test Loop according to ASTM G170-01a, Paragraph 4, Summary of Guide, attached.
In accordance with ASTM and NACE Test Method Standards; accurately simulate the physical field operating conditions and easily screen material samples fitting NACE and ISO recommended practices.
a) Study corrosion behavior and effects of field operations and oil/gas chemicals from down hole to refinery, including seawater, oxygen, CO2/H2S (and other gases) and effect of flow on the surfaces of subject screening material’s test specimen.
b) Characterize the corrosion product films that adhere on materials.
c) Study the effectiveness of the anti-corrosion inhibitor chemicals for all environments, from down hole to pipelines, to storage and refinery field applications.
d) Understand and apply the test results of the measured corrosion behavior and corrosion resistance.
