Abstract

Hydram pump is the machine that conversion potential energy (PE = mgh) of water to kinetic energy (KE = ½ mv2) in intake pipe become water hammer in casing of hydram pump. That has capability to raised water from the pump with vertical elevation H2 = + 50 m to 500 m. It needs the minimal elevation + 1 m, the minimal debit 7 litres/minute and it depends on diameter and pump type. The principal of its construction has length of intake pipe L = 5 to 10 x H1 (vertical fall).

Abstract

The Fash field is a heavy oil category managed by PT. Chevron Pacific Indonesia with sandstone rock type. So that along with the production of oil to the surface, there will be production problems such as asphaltene. To overcome the problem of asphaltene, a solvent is used to dissolve asphaltene in the form of a solvent. There are 2 methods used to perform solvent injection, namely by using a coiled tubing and by using a pump. This research will discuss the success rate of each method in the solvent treatment application and the determination of the threshold value in order to determine the right candidate well for each method of use. In determining the level of success, Minimum oil recovery for each method, namely coiled tubing and pump is 8 bopd and 4 bopd and to determine the threshold value, a parameter that has a certain value is used as a reference to maximize the use of existing methods in solvent treatment applications. The parameters used are asphaltene content (%), water cut (%), wellhead temperature (°F), and reservoir temperature (°F).

Abstract

The residual brine heat in the Geothermal Power Plant (PLTP) has the potential to be utilized to generate electricity because it still has a fairly high temperature and pressure. The method of utilizing residual brine heat is by using the Organic Rankine Cycle (ORC) which can be used to utilize heat at low temperatures. The main parameter method measured is the pressure and temperature in the working fluid circulation, hot water circulation (brine), and cooling water circulation. The ORC system uses an evaporator component as a replacement for the generator or boiler system in the Rankine cycle. The ORC system utilizes low-temperature heat sources such as Internal Combustion Engine exhaust heat, solar heat, biomass and brine from geothermal power plants. At low temperatures, organic fluids have higher cycle efficiency than water. The mass rate value in this study was 13.63 kg/s. where the turbine work is 328.07 Kw and the condenser heat transfer rate is 113.40 kj/s. The pump work is 311.8544 Kw. And the rate of heat transfer in the evaporator has an efficiency of 4.93% where the heat absorbed by the evaporator is 129.6213 kj/s.

Abstract

Hub dari mesin screw press terpasang pada poros melalui alur pasak diikat dengan elemen pasak (key) dan berfungsi untuk meneruskan daya dan putaran dari speed reduser ke worm screw,kondisi ini pada sa’at tertentu mengalami kelonggaran ketika dioperasikan, karena pengaruh friksi pada bidang pasak dengan alur pasak dari poros sehingga alur pasak dari hub yang juga ada beban dinamis puntir, rotating bending serta beban lentur memberi efek samping friksi atau gesekan pada pasak dengan alur pasak hub dari poros screw press, sehingga terjadi konsentrasi tegangan pada daerah alur pasak dan material yang mengalami fatigue atau kelelahan secara kontiniu, serta timbul retak awal pada material hub screw press, khususnya pada permukaan fillet, kemudian terus menjalar ke dalam dan akhirnya patah (fracture). Insiden kerusakan ini terjadi pada suatu pabrik pengolahan kelapa sawit secara rutin sebelum 4 (empat) bulan pakai. Oleh sebab itu perlu dilakukan penelitian, analisis, mencari dan mengetahui penyebab failure/kerusakan (Root Caused Failure Analysis). Penelitian ini diawali dengan pemeriksaan visual, kemudian dilanjutkan dengan uji laboratorium yang meliputi uji metalografi, uji fraktografi, uji kekerasan, uji komposisi kimia dan menentukan tindakan preventiv untuk meminimalisir kerusakan hub screw press. Inisiatif selanjutnya melakukan optimisasi teknik pemeliharaan terhadap mesin pabrik PKS.dengan memprioritaskan prosedur pengoperasian mesin screw press, yang sesuai standar operating prosedur (SOP buku manual) mesin pabrik produk asal, disamping itu melakukan kontrol kualitas terhadap fabrikasi material hub, seperti uji komposisi kimia, uji kekerasan, microscopic, makroscopic, uji metallographi, dan membandingkan specimen uji dengan material produk standar pabrik, diikuti dengan supervisi terhadap optimasi teknik pemeliharaan yang ditetapkan.

Abstract

Gas lock is defined as a fluid flow problem where the flow is blocked by a gas phase, inhibiting the production flow rate. This occurs due to the release of free gas in oil with a high gas-oil ratio (GOR). This condition arises when the pump intake pressure (PIP) or fluid over pump (FOP) is lower than the bubble point pressure (Pb) of the oil. Initial indications of free gas formation can be observed from erratic amp-chart readings, high annulus pressure, and the pump operating below its efficiency. To address gas lock issues in ESP pumps, additional equipment such as a gas separator can be installed below the surface, and PIP should be maintained above the Pb. The installation of a gas separator in the pump helps reduce the entry of free gas into the pump, while free gas is discharged into the annulus casing. In this thesis, the researcher uses a case study on a producing well with high GOR values of 100 mscf/day, a design rate of 850 BFPD, and a pump intake pressure (PIP) higher than the well's bubble point pressure (Pb) at 150 psi. Based on data processing using Prosper V11 software, the ESP pump in well Y was replaced from a REDA DN1300 to a REDA DN1100, resulting in a gas separator sensitivity value of 89%. The best pump efficiency achieved was 62%, and the optimal production rate obtained was 1330 RB/day.
