By replacing legacy electropneumatic valve positioners with digital, zero-bleed ones can generate significant cost savings for medium-to-large pipeline operators seeking a sure way to reduce costs, nuisance alarms, emissions and compliance issues.

By applying simultaneous fixed-film biological treatment with activated carbon polishing, the newly released Siemens PACT® AGR process offers a robust, economical and environmentally sound solution for treating industrial wastewaters, especially from refining and petrochemical production.

As a popular chemical building block, propylene is used in downstream petrochemical processes to make a number of important materials, including polypropylene, one of the best-selling plastics, as well as material that is used to produce items such as acrylic fibers and coatings, polyurethanes, and isopropyl alcohol.

Siemens is a pioneer in the use of Lamb wave transit-time sensors for clamp-on flow measurement. We call it WideBeam® – and it increases accuracy by reducing sensitivity to any changes in the fluid. How? WideBeam® technology uses the pipe wall as a waveguide to optimize the signal-to-noise ratio and provide a wider area of vibration. These high-performance sensors are designed for steel pipes, but they also work with aluminum, titanium and plastic.

With SIMATIC PDM Maintenance Station V3.0, Siemens offers an optimal tool for efficiently monitoring the condition of smart field devices, irrespective of the automation or control systems used. SIMATIC PDM is a universal, non‐proprietary tool for the configuration, parameterization, commissioning and monitoring of smart field devices. The maintenance station is based on the SIMATIC DCS PCS 7 maintenance system but is now available as a standalone system. MS can run independently of the both the customers’ automation control projects as well as with complete autonomy from the PLC/DCS process control systems being used.

After addressing the business, financial, and operating benefits of segregated ethylene spent caustic treatment in Water Recycling Efficiency In Ethylene Facilities Producing Spent Caustic, Part I: Cost, this conclusion to the story delves deeper into the process involved.

Jiujiang, a city of 5 million people, borders the edge of the Yangtze River as well as Poyang Lake, each China’s largest. To the east of the city’s residential districts, midway on a peninsula separating the two bodies of water, sits the giant petrochemical complex of the Sinopec Jiujiang Company, a subsidiary of the Sinopec Corporation, the nation’s largest refiner. Nearly 3,000 people work there.

Fracturing sand (i.e., frac sand or proppant) is a key component used in hydraulic fracturing operations that facilitates production by keeping fractures open so that oil and/or natural gas can flow freely from the formation into the casing and up to the surface. Read more to learn about automation solutions that optimize the efficiency of utilizing native Texas sand for fraccing.

Ever since Coriolis flow measurement technology achieved mainstream appeal, industry has been fervently striving to take advantage of its benefits. And while Coriolis is clearly a highly advantageous solution for many crucial flow measurement applications, it is not without flaw.

Since the first Coriolis flow sensors were introduced to the marketplace in the 1970s, the technology has evolved considerably. As the installed base for Coriolis grew, the sensors were being called upon to deliver data in environments with increasing levels of complexity. This meant that Coriolis sensors had to adapt and conform to a dizzying array of ever-changing installation requirements, process conditions, communication formats, and configuration parameters. The following article highlights four key advances in Coriolis flow measurement’s journey from the 1970s to today.

Coriolis measurement has been adopted as a default technology in many application scenarios due to its high accuracy and immunity to process variables (temperature, pressure and flow profile). However, Coriolis wasn't always widely accepted. Two applications, in particular, helped what was once a nascent flow measurement technology gain a foothold in the marketplace.

There is no doubt that the practice of hydraulic fracturing, also known as fracking, has completely changed the oil and gas landscape in recent history. There is also no doubt that this is a highly technical process.

It may not be immediately apparent just how crucial bubbles are to oil and gas operations. They play a critical role in a process known as dissolved gas flotation (DGF), which is imperative for removing contaminants. And not all bubbles are created the same.

Horizontal drilling started back in 1929 and hydraulic fracking began in 1949. However, it was not until 2003 that the horizontal drilling and hydraulic fracking processes were combined to extract gas from the Barnett Shale in north Texas. Since then, gas drilling has increased by 14 times in the United States. Given the vast shale formations throughout the United States, drilling will continue to increase for several more years.
