LESSON 3. GREEN, GREENER, THE GREENEST

Read the text and define the core points. Write the summary of it.

Biogas is basically green energy, but there are still subtle differences that are important. Bioenergy plant has chosen to divide the biogas production in a pure green line and an industrial line. It is a well-known fact that is almost impossible to initiate efficient biogas production with just manure. Typically, biologically industrial waste is added, e. g. from slaughterhouses end dairies, because it triggers the decay and thus boosts the biogas production.

The approach is also used at bioenergy plant - but according to strict parameters. In short, not all types of organic industrial waste can be added to the green line. The degassed manure should obviously be returned to the fields as a genuinely green product, and thus it can only be mixed with certain materials. Industrial waste that does not meet the criteria goes to the industrial line instead.

Although bioenergy plant for the most part is built by known technology, the pant does boost a novelty an off –site receiving station When a plant is as

huge as this one so much manure is called for that the nearest neighbor: not enough in order to restrict the transportation, a receiving station has been built 16 km from the plant. Here, truck deliver raw slurry and pick up digested slurry. Fresh manure is pumped into bioenergy plant through a pipe, ant degassed liquid manure will be returned in a parallel pipe.

The process has proved to be more expensive and demanding than expected.

Therefore, to begin with, only one race, station has been built, although two had СибАДИactually been planned. The plan now is to gather experience before the second is built. Pumping raw slurry over such large distances has also proven to more

difficult than expected. The slurry is lumpy and difficult to pump, and it requires considerably more pumping power than anticipated. More booster stations must

be built and these require power and SCADA control. However, bioenergy plant will still be repaid in 20 years.

The duo bioenergy and the plant might be extended with yet another teammate plans for an ethanol plant have in fact begun to take shape. The ethanol will be extracted from straw, and an added bonus is that the waste products of the process can be utilized. The biogas plant can benefit greatly from the sugar-like mass which is the result of the waste product. When the sugar is added in the slurry tanks, the decay is increased and the production of biogas is increased fivefold. In addition to the sugar mixture a fiber fraction is created. This can be used at the plant as a supplement to the waste that the plant combusts at its waste line. The local area cannot deliver the waste amounts needed by the plant to operate efficiently. With the liberalized waste market in mind it is uncertain how much waste can be had in the future. Therefore, a stable supplier as the plant's neighbors will be appreciated. The preliminary discussions about the ethanol plant are in progress. The goal is to start production in 2016.

LESSON 4. PROTECTION

СибАДИRead the text and define the core points. Write the summary of it.

27 childcare institutions in the municipality of Odense protected from damage from leaks and seepage from the water and heating installations.

Anker Boye, Mayor of Odense, describes the newly completed collaborative development effort with local company DanTaet as a genuine winwin project. An investment in the order of DKK 50-60.000, which protects from incurring damages easily totaling half a million DKK or more. Does that sound too good to be true? Actually, it is not according to Jens Oxenvad, Property Engineer in the City and Culture Administration of the municipality of Odense, having just completed a collaborative project in around 27 of the municipality's childcare institutions with Odense-based company DanTaet. The company is the leading developer and supplier of protection systems ensuring that leaks and seepage from water and heating installations are detected quickly avoiding costly consequential damage. 600 cubic meters of water caused major mold problems.

“We have unfortunately suffered major mold problems in several of Odense’s institutions. For instance, a leaking water pipe in a kindergarten caused 600 cubic meters of water to seep into walls and floors before the leak was discovered. This happened three months after the leak had started and the damage understandably, was comprehensive at that time”, says Jens Oxenvad, adding that on top of expenses to eradicate the mold, Odense incurs expenses for alternative housing for the users of the damaged institution while it is being renovated.

The project is of the municipality's active risk management, and the systems are now operational in 18 of Odense’s public schools and in nine of in all 120 child houses, numbering both kindergartens and nurseries.

Few but effective components

The components for leakage protection of supply water (System KMP-V) and district heating (System KMP-F) installations respectively are largely identical, consisting of electrically operated cut-off valves, control units, external sensors and Kamstrup Energy and Water Meters. The two systems have been developed in close collaboration with ultrasonic flow meter manufacturer Kamstrup, and are adapted to suit this company's flow meters.

СибАДИAlways water for fire extinguishing and cleaning

Tage Laurup, Sales Director of DanTaet, points to two motion sensors placed under the ceiling amid the long corridor in Bornehuset, Ejerslykke Nursery in Odense and explains: «Without these two sensors, the occupants would get little water, and the cleaning staff would have difficulty filling a bucket». The sensors detect motion, and the system in the basement is informed that the building is now in use, and water must be available. If the nursery’s fire cabinet is opened, the system in the basement will immediately force open the cut off valve. Hereafter, exceeding the consumption limit will only cause an alarm while the flow of water remains unimpeded. This property is essential to the emergency services' approval of the protection system in the nursery.

Property engineer: “The user - friendliness of the system has been of paramount importance – it must be easy and intuitive for users to respond when the alarm sounds”

Highly user-friendly system

The user-friendliness of the DenTaet systems has been of paramount importance to the municipality Jens Oxenved elaborates. “The managers of nurseries and kindergartens are not technicians, nor should they be; therefore the systems must be designed for use by persons with no technical skills”. Gitte Hermansen, the manager of Ejerslykke Nursery casts a glance at the two short-form guides hung on the wall above the control units that issue a text message alarm to her, and to the municipality in the face of leaks or seepage. “The guide is simple and easy to grasp, so I do not expect any difficulty when the alarm finally sounds. l can just read what to do” she says. This characterization is in line with that of the Technological Institute, which has performed a general evaluation of the KMP-V and KMP-F systems.
