The Benefits of NDT in a Gas Pipeline
Nondestructive testing (NDT) is preferred in the oil and gas industry—especially in gas pipelines. Petroleum and natural gas pose an environmental hazard to pipeline welds. Hydrogen and carbon dioxide in oil and gas, along with sulfides and other chemicals found, can cause embrittlement and corrosion of steel. Using NDT in gas pipelines can detect these issues before they become a larger ...

Release of hydrogen sulfide in a sewer system under intermittent flow conditions: the Eiceira case study, in Portugal
The presence and fate of hydrogen sulfide in wastewater systems were studied in two stretches of an intercepting sewer system located in a coastal village, in Portugal. A range of hydraulic parameters were obtained and liquid and gas phase measurements were carried out, both continuously and through intensive sampling campaigns. Upstream, where flow rates were relatively low, dissolved ...

TVOC provides low-level operator protection at oil and gas plant
Product: TVOC Industry: Petrochemical Application: Monitoring air intakes for control rooms and toxic refuge Customers: Petroleum Oil and Gas Suppliers Introduction The need for monitoring on-site control rooms and toxic refuge has been a long established application for fixed gas detection. It is usual that explosive gases are detected by catalytic style detectors, measuring LEL levels. ...

Maximizing bioreactor performance - Case Study
Paul Sauer, Associate Scientist of Protein Design Lab's Cell Culture Development Group, had two compelling reasons for specifying mass flow controllers for his work: The first was the need to acquire an array of data that would allow them to more effectively control fermentation processes; The second was the need to minimize the formation of foam in the bioreactor's headspace. To minimize foam, ...

Bringing precision to steel production - Case Study
Aluminum and steel manufacturers use mass flow controllers to inject purification, stirring and shielding gases into their melting, casting and annealing processes. Precise, automated gas flow control reduces toxic emissions and material costs. Final purification of aluminum is accomplished by bubbling a mixture of argon and chlorine gases through the molten metal. This process separates ...

Improve gas blending accuracy and save money – Case Study
For DataChem Laboratories, precision mass flow is crucial. DataChem, originally established in 1973 as part of the University of Utah's Research Institute, has grown into a world respected analytical testing laboratory. They have the important job of testing and identifying harmful industrial and environmental toxins—from lead paint found on our children's toys to methamphetamine dust ...

Delivering automation to test stations - Case Study
CeraMem Corporation is a developer of metal oxide gas concentration sensors in Waltham, MA. Their test engineers required mass flow controllers that were easy to intregrate and calibrate. They also demanded fast response and high accuracy in order to reduce test cycle length and improve the quality of the data. Test station requirements demanded that controllers were capable of adjusting ...

Determining levels of moisture permeation through Kalrez and Chemraz o-ring material
Problem Statement As the manufacturers of corrosive resistant gas cells we are often called upon to design a system for the detection of moisture in various gases. Most of our requests are to detect moisture in the low ppb levels. This can be a rather difficult task to accomplish when the surrounding environment has high levels of moisture (humidity). There are several steps that we take to ...

Wastewater force main management – internal corrosion survey using inline methods
In our first post about Wastewater Force Main Management, we looked at how preliminary analysis helps operators develop a plan for managing their system. After completing this process, operators can begin putting the plan into action with preliminary surveys on specific force mains. For those at WEFTEC, you can visit Pure Technologies at Booth #1382 to find out more information on successful ...
