One of the things that their have done is how to get the customer’s belief in their brand. Quality in every part has become the main case. Most of the companies in industry use metals as material to support their services. When the goods have been processed, it must continue with the testing. This is to prove that the goods have gone through the formation process fill in standard quality which required by the customer. There are two types of testing known as destructive testing and non-destructive testing. There are some of ways of non destructive testing methods on metals inspection has been applied in testing the quality of goods. Such as visual test, magnetic particle test, liquid penetrant, eddy current test, ultrasonic test, radiographic test in metals testing. Nondestructive testing (NDT) is the process of inspecting, testing, or evaluating materials, components or assemblies for discontinuities, or differences in characteristics without destroying the serviceability of the part or system. Radiographic Testing (RT) is a nondestructive examination technique that involves the use of either x-rays or gamma rays to view the internal structure of a component. In the petrochemical industry, Radiographic Testing is often used to inspect machinery, such as pressure vessels and valves, to detect for flaws. RT is also used to inspect weld repairs. Compared to other NDT techniques, radiography has several advantages. It is highly reproducible, can be used on a variety of materials, and the data gathered can be stored for later analysis.","PeriodicalId":105806,"journal":{"name":"MECHA JURNAL TEKNIK MESIN","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131008719","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}

Korelasi empiris memberikan pendekatan baru untuk mengetahui parameter kritikal dalam kompresor dan kemampuan prediksi terhadap peningkatan produksi. Metode ini telah diterapkan di kompresor multistage di salah satu Anjungan Offshore di Wilayah Kalimantan Timur. Parameter-parameter yang di analisis pada kompresor multistage ( C301 A/B, C302 A/C dan C303 A/B) antara lain Suction Pressure, Suction Temperature, Discharge Pressure, Discharge Temperature, Suction Flow, Suction Temperature, Speed NGP dan Speed NPT . Metode statistik yang digunakan antara lain Regression Analysis, Analysis of Variance (ANOVA) dan Main Effect Plot (MEP) dengan menggunakan software MINITAB. Hasil analisis menunjukkan parameter yang berpengaruh signifikan di kompresor C301 A/B adalah suction pressure dan speed, sedangkan untuk kompresor C302 A/C parameter yang berpengaruh signifikan adalah suction pressure, discharge pressure dan suction flow. Hasil berbeda ditunjukkan oleh kompresor C303 A/B dimana hanya discharge pressure yang berpengaruh signifikan. Hasil analisis ini juga mampu mengevaluasi serta memprediksi model optimum dari korelasi dan kombinasi parameter-parameter yang signifikan tersebut sehingga bisa gunakan sebagai acuan untuk melakukan optimasi setting parameter di proses produksi sehingga meningkatkan produksi dari sumur.","PeriodicalId":105806,"journal":{"name":"MECHA JURNAL TEKNIK MESIN","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122887322","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}

Regional water balance (integration) is important to support factory operations. Raw water is treated in the unit section to produce demin water and further process into Boiler Feed Water (BWF) to produce 80 kg/cm2 pressurized steam in the boiler unit, to meet the specifications as demin water it is necessary to carry out several treatments to remove mineral ions (cations and anions) dissolved in the air. In the mixed bed polisher, there is a resin regeneration process to eliminate saturation of the resin which can no longer bind mineral ions. Regeneration or regent is carried out after the resin pile is saturated which is characterized by an increase in product productivity conductivity with the desired product conductivity target of <0.2 μS/cm at a temperature of 25℃. The purpose of this study was to work or perform a mixed bed polisher, especially during regeneration in the demineralization unit. This research was conducted by making a framework of thought and writing work. The writing stage contains data collection, data processing and data analysis-synthesis, as well as drawing conclusions. Based on this research, the results showed that there was a decrease in the performance of the mixed bed with a bed expansion gain of 80.7% and a resin height of 2.42 m. The number of chemicals used for regeneration is 1170.7 kg consisting of HCL and NaOH so that the flow rate of demin water required to dilute the regenerant is 7,126 m3/h.\u0000\u0000 \u0000\u0000Keywords: Mixed bad Polisher, Demin water, Resin regeneration.","PeriodicalId":105806,"journal":{"name":"MECHA JURNAL TEKNIK MESIN","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125962459","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}
