70 MAKALE/ ARTICLE t Decrease of solid waste as a result of replacing solid fuel (coal) with gas t Reduction of sulfur dioxides, carbon dioxides and nitrogen oxides How it all came about The main idea of the project was to utilize 100.000 m3 of gas that was unproductively flared every day at the drilling rig in the Baltic Sea- a waste with negative environmental consequences. Only a small part of this (1 O percent) was used for the power requirements of the rig. The heat and power generating plant in Wladyslawowo turned out to be a unique enterprise in the national or even European region. it utilizes the natura! gas associated with the extraction of crude oil. At present, about 100.000 m3 of natura! gas per day are supplied via a newly laid submarine pipeline. in 2001 Energobaltic, the company that was established to carry out that investment was looking for a contractor to manage the projeci. The selected company would have to supervise the construction of an installation combining three different technological processes. These processes are .the transport of gas from the drilling rig to the shore, gas treatment on the shore and safe and reliable production of heat and power for local requirements. Following negotiations with several international companies of renown, Energobaltic conferred responsibility for the project's supervision and execution on ABB Zamech Gazpetro in February 2002. For more than a year a team of engineers and experts was engaged in the coordination of ali projeci activities. These included the process of appointing suppliers and contractors through tendering, verification of technical documentation on a current basis, supervision and coordination of work at the construction site, supervision of start-up and commissioning of the sites and the settlement and financial controlling of the projeci. The projeci was divided into two main phases. The first included construction of the heat-generating planı and district- heating system. The target was to start up the heating system no later than mid-September 2002 so !hat heat could be available for the Winter of 2002/03 heating season. Despite to very short period allowed for construction (only seven months) the deadline was met and heat supplies /. lniıial treatıneııı ofthe gas on board ıhe "Balıic-Beıa" drilliııg-rig previoıısly !his gas was wastefıı//yflared of]' ENERJi DÜNYASI KASIM 2006 "The waste-gas that was previously flared at the rig turned out to have an interesting chemical composition. it included only 45 percent methane but was very rich in heavy hydrocarbons." to town officially commenced on the 18th of September 2002. The second implementation phase included the construction of the gas supply from the offshore drilling-rig to the mainland. it also included the realization of the on-shore gas treatment and storage facility and of the gas turbines with waste-heat boiler. The whole project was complete and went into full operation on the 30th June 2003. Working to protect a sensitive location The heat and power generating planı is situated in the industrial and harbor area of Wladyslawowo. Wladyslawowo is located at the foot of the Hel Peninsula, near the Nadmorski Coastal Landscape Park. The facility has been constructed on the site of a disused coal-fired boiler and sewage treatment planı. Particular consideration was given to the aesthetic design to ensure !hat it blended well with the local environment. The town of about 12.000 inhabitants is a health resort. in the summer season, the number of inhabitants increases five-fold. The waste-gas that was previously flared at the rig turneci out to have an interesting chemical composition. it included only 45 percent methane but was very rich in heavy hydrocarbons- over 20 percent propane and butane, and its calorifıc value amounted to 54 MJ/Nm3• Therefore the heat and power generating planı was extended by a gas refining facility, where liquid fractions propane-butane and chemical gasoline are separated from the so called "wet gas". This represents an important element of the projeci in terms of income. CHP Wladyslawowo therefore now manufactures four products: electricity, heat, LPG and gasoline (CS+). After separation of LPG and CS+, a light gas (a mixture of methane and ethane) is transferred to feed gas turbines and water boilers. Liquefied propane- butane and CS+ is stored and sold. Because of its atypical chemical composition, the waste gas associated with the production of crude oil had to undergo an initial treatment on the offshore "Baltic-Beta" drilling rig 1 in the Baltic Sea (ca. l 2.
