Produced water refers to any water brought up to the surface during oil and gas production, typically as the result of drilling, exploration and hydraulic fracturing. Before disposing or reusing the water, it must be treated to extract hydrocarbons and satisfy environmental code regulations.
This year's ABB Automation & Power World, held March 25-28 in Orlando, Fla., included a broad range of need-to-know presentations for automation and power professionals on topics ranging from cybersecurity concerns to efficiency and reliability, and data power usage.
End users have struggled with different forms of device integration technology over the years, but the FDI effort aims to rationalize the worlds' leading technologies for managing information from intelligent field devices.
A new concept for an Electronic Flow Control Valve (EFCV) with pressure compensation capability is introduced. Based on its embedded sensors and micro controller, the EFCV can provide flow control without the need of load/displacement/speed information from the power elements, like hydraulic cylinders or hydraulic motors.
Recognizing the prevalence of lightning strikes in the Gulf of Mexico region, several system specifications and practices written for lightning mitigation have been applied and implemented in offshore applications over the last decade.
This paper covers the importance of securing automation devices for access internally on an Intranet, or externally over the Internet. Choosing an Ethernet Fieldbus offers the competitive advantage of speed, flexibility and accessibility though steps should be taken to secure automation devices and any associated programming workstations and servers. This paper seeks to educate the Controls Engineer on security strategies, technologies and options available.
Understanding the accuracy of a given flowmeter is an important field but it can also be misleading as different specifications are used to explain how accurate a flowmeter measurement actually measures. This paper discusses the different specifications and interprets the impact of them.
Why deal with accuracy?
The reasons for dealing with flowmeter accuracy specifications are many-folded. One important reason is from an economical point of view. The more accurate a flowmeter can measure, the more money you will save as the medium is measured with only very little inaccurately.
Another reason is in terms of dosing, where a given amount of a medium is added. This must be done with a high level of precision and the accuracy is thus important in order to dose correctly. This is critical in certain industries such as in pharma or chemical.
A third reason is in terms of billing purposes. By performing with good accuracy, you know exactly how much fluid flows into the process. Thereby, you are able to determine the right price of the product and thereby bill the customers correctly.
Therefore, knowing how much that flows through your system is paramount in order to make a profitable and solid business. You need to rely on a precise measurement with good accuracy. However, good accuracy must be obtained not only in one measurement, but in all measurements independent of the time.
Industrial control networks are highly vulnerable to intelligent remote attacks, as well as non-intelligent viruses. With threats to these networks increasing in complexity and scope, decision makers need to take action before it's too late.
