Case Studies

MULTIPHASE FLOW LOOP

Cortest recently was granted permission to begin the design and construction of an inclinable, multiphase flow loop. This multiphase flow loop was designed to the clients requirements and specifications and was to be able to provide flow of water, oil, gas, and other substances through a 4 inch and/or a 1 inch loop, to allow the operators to observe, analyze, and study the flow properties under certain conditions. These conditions include but are not limited to, high temperature, high pressure, high/low flow rate, mixed phase, mixed liquid/gas, and more. Analysis capabilities include Laser Doppler, Particle Image Velocimetry, Particle Shadow Sizing, Tomography, Sheer Stress measurements, and others. Thanks to Cortest’s command hub, the operator can control and monitor all aspects of the loops activity and instrumentation from one room. This project is a true testament to the scope of projects and capabilities here at Cortest.

NEW LABORATORY SUPPLY

Recently, a prominent petroleum research institute in the United Arab Emirates (U.A.E.) sought an extensive supply of customized laboratory equipment to equip their newly constructed, state-of-the-art electrochemistry and corrosion laboratories. The equipment would be used for many different applications but largely to evaluate corrosion inhibitors through bubble tests, foaming tests, interface performance tests, contact time tests, condensing corrosion tests, emulsion tests, and jet impingement tests. The scope of supply ranged from simple graduated cylinders to highly customized, high pressure, and high temperature test systems. Cortest, Inc. was awarded the contract for this supply. Following the contract award, the Cortest team conducted a site visit at which time a project kick-off meeting took place followed by a thorough site tour to better understand the institute’s vision for where all of the different equipment would be installed. Following the site visit, Cortest embarked on a rigorous design phase in which equipment design ideas were passed back and forth with the customer until a final design for each test system was reached.

20-LITER C-276 AUTOCLAVE SYSTEM WITH SIGHT GLASS WINDOWS

Recently, a major oil company in the Pacific Rim region sought to purchase a customized autoclave lid assembly that would allow them to study the effects high-velocity liquid flow on the corrosion rate of pipeline materials when exposed to high pressure and high temperature within an autoclave. The customer’s goal was to be able to simulate a flowing pipeline without the need to build a large, costly, flow loop. Cortest was awarded a contract to develop what would be called the “Flow-Tube Lid Assembly.” The assembly would need to work at temperatures up to 204°C and at pressures up to 3,000 PSI. The main objective however was to see the maximum single phase flow rate that could be achieved through a series of cylindrical electrodes that simulated the pipeline. After final testing proved the flow-tube lid assembly provided a measurable liquid flow rate of up to 1.4 m/sec.

NACE TM0177 & TM0284 LABORATORY

Recently, a large steel mill in South America sought to develop a new state-of-the-art laboratory to conduct testing under NACE TM0177 and NACE TM0284. An existing building would be renovated to house the new laboratory. The scope of supply would include Proof Rings, HIC tanks, fume hoods, duct work, exhaust gas neutralization tanks, H2S scrubbers, gas bottle storage cabinets, gas sensors, and a complete laboratory monitoring system. After conducting a site visit and holding technical discussions, Cortest, Inc. was awarded the contract for this supply. Upon being awarded the supply contract, Cortest embarked on a rigorous design phase in which all equipment was designed and laid out to fit within the renovated building that the customer had planned to use for the new laboratory. Equipment positioning, gas sensor locations, duct work routing and sizing, gas line routing, and exterior foundation requirements were all carefully planned out and presented to the customer so that they could begin preparing the site for installation.
