Abstract

Dalam pemanfaatan langsung brine untuk budidaya ikan gurame perlu diketahui kondisi optimal desain dan operasi. Desain sistem pemanfaatan langsung untuk budidaya ikan mencakup proses dan peralatan pada tiga komponen yaitu desain kolam, sistem penukar panas (heat exchanger) dan pipa distribusi fluida geotermal maupun air permukaan. Sistem pemanfaatan langsung ini dilengkapi dengan unit pompa dan kolam pendingin sisa proses perpindahan panas. Unit pompa digunakan untuk mengalirkan air permukaan pada elevasi dibawah tempat budidaya, dibutuhkan beberapa peralatan dalam sistem budidaya ikan gurame seperti double pipe heat exchanger, pompa brine, pompa air. Energi panas yang dibutuhkan untuk menaikan temperatur air permukaan dari temperatur 16ᵒC hingga temperatur optimum 28ᵒC sebesar 68,11 kW. Secara keekonomian proyek pemanfaatan brine untuk budidaya ikan gurame layak unttuk dilakukan, dengan melihat NPV yang positif, IRR sebesar 41% dan POT selama 3 tahun.

Abstract

Injection water used as a pressure fluid in water flooding have an impact in its quality problems, consist of oil content and emulsion block. because the oil acts as an adhesive on the solids can causes blockages in the pores of the rock. This has the potential to cause low oil recovery factor in the water flooding process. The injection water (IW) and formation water (FW need to be analyzed in the laboratory before being injected into the reservoir with the aim that the injection water can be used as a pressure fluid in the water flooding process. Based on the results of laboratory tests, injection water (IW) shows a high concentration of oil content (50.55 mg/L) so that it can form emulsion blocks,and can cause plugging in rock pores. For this reason, the solution chosen to solve the emulsion block problem in this study is to use chemical treatment. The problem of oil content and emulsion block can be overcome by using a reverse demulsifier, at a concentration of 50 mg/L the reverse demulsifier can improve the injection water quality from poor water quality (oil content 50.55 mg/L) to good water quality (oil content 15.89 mg/L).
