Untuk menjamin kebutuhan listriknya, PLTU Pacitan harus menjaga peralatannya, salah satunya turbin uap. Turbin uap merupakan alat yang sangat penting keberadaannya karena berfungsi untuk menghasilkan putaran yang nantinya akan memutar generator. Supaya proses tersebut lancar, maka perlu dilakukan perawatan dan dievaluasi unjuk kerjanya secara rutin. Dalam melakukan evaluasi dan optimalisasi, ada beberapa parameter yang harus diperhatikan. Antara lain: daya turbin teoritis, daya turbin aktual, steam rate, dan efisiensi total dari turbin uap tersebut. Berdasarkan hasil analisis yang telah dilakukan, dapat diketahui bahwa terjadi peningkatan konsumsi uap tetapi menghasilkan daya output generator yang lebih rendah. Setelah dilakukan perhitungan, ditemukan bahwa terjadi penurunan efisiensi sebesar 16%, yaitu dari kondisi commissioning (86%) ke kondisi operasi (69%) Kemungkinan hal ini disebabkan karena heat loss yang terjadi pada pipa main steam. Setelah dilakukan optimalisasi berupa perbaikan pada insulasi pipa main steam, efisiensi turbin dapat ditingkatkan sebesar 2%, yaitu dari 69% menjadi 71%.","PeriodicalId":345977,"journal":{"name":"Indonesian Journal of Energy and Mineral","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123678629","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this method, fluid is injected continuously into some injection wells to displace oil and obtain production from other wells. However, there are problems with steamflood process that are still not optimally solved. There is an early channeling of steam under the cap rock to the production well which leads to investigating a solution by co-injecting gases to steamflooding pro\u0002cesses. Carbon dioxide is co-injected with steam to form gas-drive so it is expected to be able to add sweep in reservoir and also increase oil in place as gas dissolves in oil. Thermal simulation was carried out in this study using CMG STARS™ reservoir simulator by constructing two kind of injection schemes; steamflood only and steam-CO2 to study the performance of each method. The analysis in this research investigates the effects of steam-gas simultaneous injection in a heavy\u0002oil recovery process specifically to the microscopic and macroscopic efficiencies. The sensitivity of some parameters in the simulation including injection rate, steam quality and slug size of gases injected are also evaluated. The result of simulation shows the highest efficiency from field-scale model is obtained from steam-CO2 method. From sensitivity analysis, it is shown that the increase of injection rate and steam quality of gas injected gives the higher recovery, but the oil recovery decreases as the slug size of gas increasing.","PeriodicalId":345977,"journal":{"name":"Indonesian Journal of Energy and Mineral","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132199534","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
