BPPT, collaborating with PTPN 5 in the Insinas Flagship program, built a pilot plant for biogasproduction from Palm Oil Mill Effluent (POME) with a capacity of 700 kW. The reactor used in this pilotproject is a Continuous Stirred Tank Reactor (CSTR) which is the most important operating unit forproducing biogas from POME. Therefore, the selection of the CSTR foundation is crucial since themain process occurs in the reactor. The scope of this activity is to realize the final design into theconstruction of a CSTR pilot plant. Several types of foundations were studied, starting from shallowfoundation type such as tread foundation, deep foundation, until combining shallow foundation typewith deep foundation type. The evaluation of existing data and design review indicates that the use ofMat Foundation is not suitable due to soil condition at a depth of 0–5m which is in the form of sandyloam soil with an NSPT value of less than 20. The selection of Piles is based on the calculations usingtotal vertical load of 3035,37 ton and total horizontal load of 542,57 tons. Considering the availability ofmaterials and time concern, the recommended foundation type is pile with a diameter of 600 mm typeB and a length of 12 m.","PeriodicalId":294870,"journal":{"name":"Jurnal Energi dan Lingkungan (Enerlink)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129836139","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 the process of its processing into Crude PalmOil (CPO), the palm oil processing industry produces various types of waste, including liquid wasteknown as Palm Oil Mill Effluent (POME). POME contains organic matter that is high enough so it mustbe processed before being discarded into the environment. During this time, POME is treated usinganaerobic ponds which are quite large and produce metana gas. Metanae gas has a high level ofemissions, but it potential to become an energy source if it is utilized. Therefore, BPPT in collaborationwith PT. Perkebunan Nusantara 5 built a biogas production pilot plant from POME equivalent to 700kWfor boiler fuel at PKS Sei Pagar, Kampar Regency, Riau Province. The process of converting POMEinto biogas uses Continuous Stirred Tank Reactor (CSTR) technology. The research aims to choosethe best roof tank design for CSTR. The method used is the Pahl and Beitz method and the House ofQuality. The result of the study are the best specification planning data, which is 1400 mm in diameterand the construction site position at a height of 15350 mm from the bottom of the reactor, with use aninternal support column, with the best variant chosen is the fixed roof type with dome shape.","PeriodicalId":294870,"journal":{"name":"Jurnal Energi dan Lingkungan (Enerlink)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115548364","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}

The purpose of this paper is to present a technoeconomic study on the production of biomass-based propylene glycol via glycerol hydrogenolysis,considering hydrogen feeds that partially or fully utilize renewable sources. For analysis andcalculation, computer simulations are carried out using the Aspen Hysys V11 simulator. The technoeconomic analysis is performed by modelling the propylene glycol synthesis process from glycerol,which is then used to calculate the facility capital cost and estimate operating costs to obtain an annualreturn on investment. Sensitivity analysis is also conducted for several parameters on a 36,000ton/year propylene glycol plant. The results showed the production cost was 0.76 USD/kg or 10,802IDR/kg when the hydrogen is generated from the natural gas steam-methane reforming (SMR)process. If the hydrogen is produced from the glycerol steam reforming process, which is fullyrenewable, the plant is not feasible, as indicated by a negative net present value (NPV).","PeriodicalId":294870,"journal":{"name":"Jurnal Energi dan Lingkungan (Enerlink)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132056098","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}

This processing also generates waste like empty fruit bunches (EFB), shells, fiber, and palm oilmill effluent (POME). POME has a high content of chemical oxygen demand (COD), approximately30,000-80,000 mg/L, which is usually fermented by bacteria. This fermentation mechanism can beused to produce biogas containing methane in a continuous stirred tank reactor (CSTR). Since POMEor organic materials for biogas production generally contain sludge, the biogas production processshould have an agitator to mix sediment in the base reactor and improve biogas production. Thisresearch aims to determine the agitator's specifications for the biogas pilot plant in PKS Sei Pagar,consisting of power type and type of stirrer include diameter calculation, geometry, and powercalculation. The agitator's power and geometry are determined based on input data from the datasheetreactor and the efficiency of the stirrer is calculated by Reynolds reynolds numbers. From thisresearch's calculations, an agitator geometry for the biogas pilot plant in PKS Sei Pagar had a length of0.875 m, a width of 0.7 m, and a height of 3.5 m. This research also obtained that the motor power resultwas 23.55 HP.
