Electricity, steam, flares / At Moerdijk, SNC has its own co-generation plant, which generates a large proportion of the electricity the site needs. Any additional power required is drawn from the national grid. Steam is also raised on-site by this co-generation plant and several processing plants. Any more steam that may be required comes from a co-generation plant located close by. At Pernis, SNC is supplied with electricity, steam and other utilities by SNR. It has been agreed with the Dutch government that SNC will have world-class energy-efficient processes in place by the year 2012. Plants in Moerdijk and Pernis are connected to flaring systems. Flares are tall stacks that prevent uncombusted gas from entering the atmosphere during start-up and shutdown and in case of malfunctions; the only way to dispose of gases rapidly, safely and in an environmentally friendly way is to burn them at a great height. SNC strives to minimize any nuisance in the immediate vicinity. Electricity, steam, flares Elektriciteit, stoom, fak- Other facilities A network providing water for fire-fighting is installed in and around the plants and other units and offices. All the plants are also connected to sewer systems. Wastewater and process water from the various plants are treated before being discharged into the surface water. At Pernis, this is done in SNR’s treatment units. Water to be discharged from the Moerdijk plant is pretreated on site, and further treatment is carried out off-site by the West Brabant Water Board. The production processes generate a great deal of heat and this is recycled internally wherever possible. However, some has to be discharged as waste heat in the cooling water, which is drawn from the Oude Maas and Nieuwe Maas rivers (Pernis) and the Hollandsch Diep (Moerdijk). The vast majority of feedstocks and finished products are delivered on site and shipped off-site by pipeline and waterway. Road and rail tankers account for approximately 10 per cent of the volume. Specially equipped storage sites allow the temporary storage of packaged waste products before they are removed to authorized treatment and disposal sites. Flaring system at Pernis. Pernis discharges large volumes of treated process and cooling water. Health, Safety, Well-being and the Environment The aspects of health, safety, well-being and the environment take a central role throughout operational management. The people working in Moerdijk and Pernis must be able to do so safely. And people living in the vicinity and our customers must also be confident that they will not suffer any harmful consequences from SNC’s activities and products. The company has a clear policy, with clearly defined procedures and guidelines to meet the strict criteria for health, safety, well-being and the environment. Its norms and values demand full compliance with health, safety, well-being and environment rules, exemplary leadership and teamwork on the part of employees, and customer-focus and good relations with business partners, government and local residents. The results relating to health, safety, well-being and the environment are communicated each year in a public report. More information about this is available on our website, as well as the full text of the most recent annual report.
Working with others / Various companies in the vicinity of SNC’s Moerdijk and Pernis sites purchase products from SNC and process them further. This has economic advantages, and more importantly involves fewer risks for people and the environment due to the short distances the hazardous materials are transported through pipelines. And there is, of course, close partnership with Shell Nederland Raffinaderij in Pernis, which not only provides most of SNC’s feedstocks but also renders various services, in particular for the Pernis site. Working with others Impermeable paving limits the consequences of any leakage. Information about nuisance Despite all the precautionary measures, incidents may occasionally occur. This might cause a nuisance to people both on and off-site, and beyond the perimeter fence people may be inconvenienced by noxious odours, noise and flaring. In addition to these incidents, maintenance and other work may also constitute a nuisance. If it is obvious that particular activities will cause a nuisance, Shell informs the neighbourhood in advance. Information is also provided as rapidly as possible when incidents do occur. That is not always easy as it usually takes some time before the causes have been traced and appropriate measures taken. The second styrene and propylene oxide plant at Moerdijk. Shell does all it can to alleviate people’s concerns by providing as much information as it can as soon as it can. Obviously, we still consider any incident to be one too many and therefore give the highest priority to prevention.
