Kertas ini membincangkan kaedah reka bentuk uji kaji untuk menghasilkan penderia Tomografi Kemuatan Elektrik (TKE) yang optimum bagi aplikasi gas dan minyak. Fokus kaedah ini adalah untuk mengurangkan kesan data TKE ternormal yang terlajak dan lajak bawah. Kaedah reka bentuk uji kaji yang digunakan adalah jenis reka bentuk faktorial 2k. Data TKE berdasarkan parameter penderia digunakan untuk menilai hubungan antara faktor atau masukan (iaitu parameter TKE) dan sambutan atau keluaran (iaitu data TKE ternormal yang terlajak dan lajak bawah). Hasil uji kaji menunjukkan bahawa teknik reka bentuk uji kaji dapat digunakan untuk menentukan hubungan atau pengaruh parameter pengesan terhadap kesan data TKE ternormal yang terlajak dan lajak bawah bagi menghasilkan penderia TKE yang optimum. Kata kunci: Reka bentuk uji kaji; tomografi kemuatan elektrik; pengoptimuman penderia This paper discusses the Design of Experiment (DOE) method to design an optimum Electrical Capacitance Tomography (ECT) sensor for gas–oil flows. The method has focused mainly on eliminating overshoots and undershoots in normalized ECT data. The DOE technique employed was an implementation of a 2k factorial design. ECT data based on ECT sensor parameters were used to evaluate the interaction among factors or inputs (i.e. ECT parameters) and the responses or outputs (i.e. normalized ECT data overshoot or undershoot) The results demonstrate the feasibility of using DOE to determine the interaction or influence of sensor parameters on the severity of normalized ECT data overshoots and undershoots and to facilitate the design of the most optimum ECT sensor for a particular application. Key words: Design of experiment; electrical capacitance tomography; sensor optimization

Electrical capacitance tomography (ECT) was used to image various two-phase gas-oil flows in a 3-inch pressurized test loop. ECT is a novel non-invasive technique for imaging mixtures of electrically non-conducting substances. One of its most promising applications is the visualization of gas-oil flows. This work presents a series imaging experiments using a pressure-resistant ECT sensor. Varying the oil and gas flow rates, different flow regimes were established in the test loop. ECT images were obtained for each case and compared with (a) the flow observed through a transparent section in the loop and (b) the prediction of the Taitel-Duckler flow map. The results confirm the suitability of ECT for imaging gas-oil flows.
