Joint Venture. Cooling Tower G reached mechanical completion in December 2004. Concurrently with the completion of Cooling Tower H the project as a whole became operative in April 2005.


 


Rehabilitation of Demineralized Water Unit
Engineering, procurement and supervisory services contract of € 2.946.560 was signed with OTV (France) on April 10, 2002. The firm has completed engineering work and shipment of equipment and materials in 2003. In 2004, bidding for the construction job was started. Construction contract awarded to MARSİS İNŞ. A.Ş. was signed on July 8th, 2004. Construction work was completed in July 2005. The unit is fully operative.



Debottlenecking of Steam Generation Unit
Technical feasibility study of this modification which will enable boilers to utilize natural gas in addition to fuel-oil were assigned to MITSUBISHI (Japan) in 2000. Engineering, procurement and supervisory services have been opened to bidding in 2001. Contract award stage has been reached in 2002. Bidding procedure for engineering, procurement and supervisory services of the other project package namely the installation of the Second Steam Production Unit has been started in 2002. However, in 2003, during re-evaluation of investment projects with the aim to cut investment expenditures both bidding procedures were cancelled. In October 2004, a new bidding was opened for lump-sum turnkey supply of detailed engineering, equipment, materials and construction work covering natural gas conversion and rehabilitation of four existing boilers, 50 MW gas turbine generator and heat recovery system. Contract of 53.019.325.-Euro plus 19.459.800.-Swiss Francs was enacted with ANSALDO CALDAIE (Italy) – TOKAR A.Ş. consortium on March 25th, 2005. br>

As of end of 2007, four boilers whose modifications have been completed was put into operation. The installations of control system of Turbines No.1 and 2 have been completed and already put into service. The Gas Turbine and Gas Turbine Heat Regaining (Recovery) Unit have been put into operation. The installation of 154 KVA shalt region (field) has been completed. The study on the provisional acceptance (approval) of the whole project has been started and it is expected to be finished by the end of 2008.


 


Chlorine Alkali Plant - Rehabilitation of Electrolyzer System
Chlorine Alkali Plant has produced chlorine using mercury cell electrolysis technology until 1997. After a two-staged investment, in 2000, mercury cells were dismantled and membrane cell technology was adopted in 42 membrane cells. In the new technology, however, the useful life of anodes and cathodes is limited to 6 years, the renewal of these has become necessary to maintain the production of chlorine in this plant and production of VCM and PVC in the Complex. The project also comprises the installation of an additional membrane cell to compensate for chlorine shortages during project implementation. An agreement was signed on 1st August, 2006 with Chlorine Engineers Corporation Ltd. (Japan) for supply of anodes and meshes. Contract negotiations are being held for other parts of the project with the same firm. An agreement has been signed; On 01.08.2006, with a validity of 30 months covering a value of 325 008 000 JPY for the renewal (replacement) of Electrodes and procurement of Meshes, on 31.10.2006, with a validity of 18 months covering a value of 221 816 000 JPY for the procurement of Membrane Elements (components), On 11.01.2007, with a validity of 6 months covering a value of 288 000 000 JPY for the procurement of Complete Cells, Spare Anodes and Spare Cathodes. The agreement covers also the renewal (replacement) of Piping Materials and related Engineering Services.< br> Concerning the renewal (replacement) of Anodes and procurement of Meshes, as of end of 2007 ,out of 1776 pieces of Anode Meshes, 1192 pieces has been procured and their payment have already been effected. Within the framework of Mesh Replacement (Renewal) project, ,out of 444 pieces of Anode Elements, 132 pieces has been repaired within the year of 2007. The procurement of Cell System Membrane Elements has been completed. The procurement and shipment of Complete Cell System, the renewal (replacement) of piping materials have been completed by December 2007. Within the same period the basic and detailed engineering studies have been completed. An order has been given for the purchase of Cell System Piping Materials. This Project will be continued in 2008 also.
