Pabrik Tetrafluoroethylene (TFE) dari Chlorodifluoromethane (CDM) direncanakan akan didirikan di Cilegon, Banten dngan luas area 120.000 m2 dan menyerap 278 pekerja. TFE merupakan bahan baku Polytetrafluoro ethylene (PTFE). Hampir 99,9 % produksi TFE dunia pada akhirnya diolah lebih lanjut menjadi PTFE. Tahap proses produksi TFE adalah sebagai berikut : penguapan bahan baku CDM, reaksi pembentukan TFE dan HCl di reaktor furnace, absorpsi HCl di absorber, dan pemurnian TFE di Stripping Column. Proses tersebut menghasilkan larutan HCl yang disimpan di Tanki Penyimpanan (T-03) dan TFE yang kemudian disimpan di Tanki Penyimpanan (T-02). Kebutuhan CDM 99,90% sebagai bahan baku adalah 38.860 ton/tahun, produksi HCl 37% adalah 43.000 ton/tahun. Kebutuhan utilitas meliputi steam sebanyak 3536 ton/tahun, udara 266.112 m3/tahun, air proses 39.180 ton/tahun, listrik 19.132,65 kW, bahan bakar 4196 ton/tahun, refrigerant 25,7 ton/tahun. Modal tetap yang diperlukan sebesar US $22.488.088,51 modal kerjanya US $ 56.180.376,78 Manufacturing cost sebesar US $25.617.492,89 dengan general expenses sebesar Rp 198.856.188.362,90 + US $ 3.606.427,22. Keuntungan sebelum pajak Rp 93.173.570.000,00 dan keuntungan sesudah pajak (PPh 30%) Rp 65.221.499.000,00. Dari hasil perhitungan diperoleh Return on Investment (ROI) sebelum pajak 45,53 %, sesudah pajak 31,87 %. Pay Out Time (POT) sebelum pajak 1,80 tahun, sesudah pajak 2,39 tahun. Break Even Point52,47%; Shut Down Point39,13 %, dan Discounted Cash Flow Rate Of Return33,28 %. Dari segi proses, pabrik dikategorikan beresiko tinggi. Berdasarkan hasil perhitungan evaluasi ekonomi, pabrik dapat dikategorikan beresiko tinggi sehingga pabrik TFE dari CDM dengan kapasitas 20.000 ton/tahun cukup menarik untuk dikaji lebih lanjut.

FactoryTFEofCDMwith a capacity of20.000 tons/year is planned to be established in Cilegon, Banten with a land area of 120.000 m2 and absorb 278 workforces. Tetrafluoroethylene (TFE) is the raw material ofPolytetrafluoroethylene (PTFE). Finally, almost99,9 % ofTFEproductionwill be used to produce PTFE. The manufacturing process consist of the following steps : vaporizing the raw material (CDM), formation of TFE and HCl on the Furnace Reactor, absorption of HCl on Absorber, and purification of TFE on Stripping Column. The process will result HCl solution stored in Strorage Tank (T-03) and TFE 96,5% stored in Storage Tank (T-02). The raw material need for the production is CDM 99,90% of 38.860 tons/year, and will result HCl 37% of 43.000 tons/year. The utility need in the form of steam at 3536 tons/year, the compressed air of 266.112 m3/year, the process water of 39.180 tons/year, electricity demand of 19.132,65 kW, fuel oil amounting to 4.196 tons/year, refrigerant of 25,7 tons/year. Economics evaluatin shows that design plant requires fixed capital investment of US $22.488.088,51; working capital ofUS $ 56.180.376,78 manufacturing cost ofUS $25.617.492,89; general expenses of Rp 198.856.188.362,90 + US $ 3.606.427,22; profit before tax of Rp 93.173.570.000,00 and profit after tax of Rp 65.221.499.000,00 (Revenue tax of 30%); Return on Investment (ROI) before tax of45,53 %; ROI after tax of31,87 %; Pay Out Time (POT) before tax1,80years, POT after tax of2,39 years. Break Even Point of 52,47%; Shut Down Point of 39,13 %, and Discounted Cash Flow Rate Of Return of 33,28 %. In term of process, the plant is classified as high-risk plant. In term of economic evaluation in 2011, is still sufficiently qualified for high-risk plant so feasible for further development.
