wireless technology improves visibility»

A move to automated measurements, via wireless technology, has offered greater process visibility for one gas storage operator which has allowed it to work much closer to capacity.

RWE Gas Storage is an underground gas storage operator in the Czech Republic, operating six facilities with a total capacity of almost three billion cubic metres. Gas is stored in porous underground facilities during low-off take periods and supplied to users when demand peaks.

The facility has active operating reserves of 900 million cubic meters with a current maximum daily output of 15 million cubic meters and is supplied by 47 production wells via an underground pipeline. Incoming gas is filtered and metered, then compressor units generate the necessary injection pressure. After the gas cooling process, the gas is pumped through high-pressure pipes into wells connecting to the storage caverns.

The company is continually looking to improve the overall effectiveness of its underground gas storage facilities as measured by the maximum daily input and output. To improve the total amounts required better control, which required higher visibility into the process. However, manually reading over 100 pressure and temperature measurements took around two hours every shift. Having so many manually read gauges was a particular problem when the gas injection rate was higher. This required manual supervision along the entire pipeline, which utilised most of the operations resources. Automating these measurements would give operators greater visibility into the process and increase their efficiency, which would enable them to perform other, more important activities.

As well as gaining access to diagnostic data from existing control valves new online pressure, temperature and level measurements were required. Improved visibility to the process would enable operators to run the facility closer to capacity minimising downtime by detecting problems that would, otherwise, lead to unplanned maintenance. This would help to increase overall input and output at the facility.

Time limits
The difficulty was completing the necessary work in the limited time available. The upgrade needed to be performed in a short space of time as any planned maintenance or upgrade projects at the facility can only be performed during two short periods – about two weeks in the autumn and again in the spring – when neither injection nor withdrawal takes place. Such tasks need to be carefully planned, and even then there are limitations in terms of the size of project that can be completed within the tight timeframe. The scale of the project, including upgrades to existing valves and installation of over 100 new measurement points, would be difficult to complete in the time available.

To add to the difficulty of the task, there was no available existing cabling infrastructure to support the new digital measurement devices, and a lack of available I/O cards in the control host.

RWE investigated the possibility of installing new cabling throughout the facility to connect the new and upgraded devices, but installation could not be accomplished in the two-week window. Even if the upgrade were divided into smaller projects it was still not possible to complete within the timeframe. There was also no possibility of increasing the shutdown period. Every day the facility was not available to withdraw gas would cost RWE an estimated $250,000 in lost income. A wired solution was therefore not an option.

The use of wireless technology would remove the need to install new cabling, significantly reducing the overall upgrade project time, making the project more manageable and ensuring it could be completed without additional plant downtime. RWE estimated that upgrade projects using wireless take only a quarter of the time required to install wired devices.

Gaining diagnostics capabilities
The company selected Smart Wireless technology from Emerson Process Management which is based on IEC 62591 (WirelessHART) communications. The availability of HART data, including diagnostics from new and existing devices, was a significant reason for selecting this technology. Having the opportunity to diagnose potential device problems quickly and easily without having to go out into the field could further improve operator efficiency at the facility.

Another advantage of Smart Wireless technology was the ability for RWE to continue to operate injection/withdrawal even when wireless transmitters were being installed. Unlike a wired solution, Smart Wireless did not require new I/O cards in the control host. Smart Wireless gateways were merely added to the existing Modbus network and all data from the wireless transmitters was then available within the existing control system. This also meant that the instrumentation upgrade did not have to be completed within the allotted two-week downtime. Tasks could be split into manageable sections and implemented ‘live’, with no concern about overrunning and affecting normal operations.

Five separate wireless networks were installed using five gateways to deliver data from across the entire 50,000-m2 facility back into the control system. Over 100 new Smart Wireless devices were installed. Predominantly these were wireless pressure and temperature transmitters, but a number of Guided Wave Radar level transmitters and control valves were also connected using Emerson’s THUM adapters.

The pressure and temperature transmitters now provide continuous measurement of gas at different sections of the pipeline to calculate volume of gas. Other applications include measuring boiler oil level using the THUM adapters to connect to Rosemount 5300 Guided Wave Radars, and monitoring pipeline microfilters using wireless pressure transmitters to detect changes caused by blocked filters. Within the gas cooling section of the facility, existing Fisher control valves now have THUM adapters installed to provide additional diagnostic information.

By implementing wireless, rather than a wired solution, the company saved around 20% on the cost of installation and commissioning. The total saving is much higher considering the potential lost income from the plant being unavailable during the required extended shutdown period. Having installed the wireless networks, the company is also saving 10% per year on maintenance costs. Remote online access to diagnostic information has enabled potential problems with instruments to be identified and corrected earlier, before poor measurements affect the process. Access to online data also reduces the number of trips into the field as problems can be spotted and often solved without leaving the control room.

The wireless network is able to work without failure or lost transmissions despite the distance between devices being up to 200m with an environment that includes masonry/steel construction.

Emerson’s AMS Suite predictive maintenance software is used to monitor network performance. During the project phase, this was also used to help calibrate instruments. AMS Suite is now used to provide ongoing device and wireless network diagnostics. The next planned step for the company is to export this data into its own management reporting system.

Crown Capital Eco/biomass Boiler Addresses Alaskans' Environmental, Economic Concerns

The heavily forested city of Ketchikan, Alaska, is built on rock and surrounded by water. Every commodity that comes into Ketchikan must arrive by sea or air. The use of fuel oil is problematic for both economic and environmental reasons because the oil must be obtained and refined elsewhere and transported (using additional fuel). What's more, fuel oil is subject to price instability.

Southeast Alaska Discovery Center in Ketchikan, which provides information to more than a million visitors each year, is the site of a pilot biomass boiler system now coming to life. Two oil-fired boilers serving the 250,000-sq-ft center were replaced with a highly efficient system fueled by local wood. Manufactured by Hurst Boiler & Welding Company Inc., the hot-water boiler was custom-designed to fit within very limited indoor space.


Under the direction of E. Dane Ash, project manager for Tyonek-Alcan Pacific LLC, the biomass boiler system was developed with Hurst representative Gregory W. Smith of Global Energy Solutions Inc. to address environmental concerns, as well as issues related to building space, fuel costs, comfort, reliability, and simplicity of operation.

https://forums.digitalpoint.com/threads/crown-capital-eco-biomass-boiler-addresses-alaskans-environmental-economic-concerns.2631317/

The new boiler is located on the lower level of the Discovery Center, which requires heating for a minimum of nine months a year. Local wood densified into fuel pucks is delivered to an elevated walking-floor storage bin in a vestibule area built to protect against excessive moisture. (The biomass-fired boiler can burn any wood product with up to 50-percent moisture content.) An auger moves pucks from the storage area to a metering bin and into the boiler. Freezing is not an issue because the walking floor easily breaks up any frozen contents.

The boiler system was designed to highlight how biomass can reduce or eliminate the use of fossil fuels. Visitors can see the boiler operate through specially designed windows. In the hall just outside of the boiler room, the noise level and ambient temperature is consistent with the rest of the building.

Savings

Fuel costs have been cut by two-thirds. The densified pucks are used with almost no residual ash; eventually, however, tree clippings from the Ketchikan walking trails will be ground and fed into the boiler, eliminating the need for transport to a landfill, burning, and other methods of disposal.

The Boiler

The Hurst S100 Series Fire Tube 27 HP Hydronic Water Heating Boiler features a pre-heater to optimize combustion and an underfeed stoker with dry-ash-removal system.

Results

The system easily can be replicated for heat or heat/power generation up to 20,000 kw. In June 2011, Smith served as a keynote speaker for the fifth annual Native American Economic Development Conference in Anaheim, Calif., where he described the initiatives being implemented in Ketchikan and shared success stories of biomass-fired boiler systems installed on institutional campuses and in manufacturing facilities throughout the United States, particularly in challenging and remote locations. Systems include municipal solid waste, as well as woody biomass for steam production and steam to power.

Crown Capital Eco Management Indonesia Fraud - Fraudsters attack even natural disasters victims

 Fraudsters attack even natural disasters victims

-Natural Disasters Victims: Scammers Wait until we are in our Lowest

Opportunists prey on natural disasters’ victims and even those who want to help. They would not miss any single chance that they could profit something from any kind of people by taking advantage of their weaknesses. Victims are at their most desperate state and scammers see this as an opportunity to deceive them.

“After practically every disaster, in the United States or abroad, charity scams pop up,” says John Breyault, vice president of the National Consumers League. “We saw charity scams pop up after Hurricane Katrina, the earthquake in Haiti and the Indonesian tsunami, to name just a few.”

These frauds come in various shapes and sizes as well as the scammers. They would take advantage the helplessness of the victims, they will show up and their front door, offer help and after they collected the payment in advance they would not show-up afterwards or worse make a bigger damage on the victim’s properties.

Beware of email scams, through email fraud they can easily target victims during in time of need. Although natural disaster’s victims are not their target rather potential donors after the disaster are being preyed.

Following a number of cases against email frauds after a disaster, the U.S. Department of Justice established the National Center for Disaster Fraud. Email and social medias are often also being used, urging you to click on a photo and then would ask for many things after that will lead you to send out money. The department insisted not to click on links instead independently seek information about charities you are interested in helping. Better yet, go directly to well known charities or charities that you already know.

Request of money donations are automatically considered as illegitimate, no record will be provided if the said organization did received the money and on your part you will not have a record for tax purposes. It is not advisable to make donations.

It will be hard to be rational during a time of calamity but take time to think about things because more often than not being impulsive will worsen things. Number one rule that you must remember is never send out or give money until the work is done or the product is at hand. Government is sure to help you, better wait for their action before making decisions on your own.

If you would like to help out, go to reputable charities and send out help yourselves. Help also comes in different shapes and sizes, as much as possible avoid sending out money to help.

You must keep in mind that although there are good people out there, scammers are also not far. It is a matter of being rational and intelligent more especially in worse times. Double check everything first, it is better sure than sorry.
