CO2 is one of the components that needs to be separated from natural gas. The CO2 concentration of natural gas varies from a content of less than 20 mole % to more than 80 mole%. There is a problem when the content of CO2 is very high so it is necessary to modify the CO2 level reduction by modifying the equipment or changing the operating conditions to meet the desired CO2 purity. In this study, field conditions and characteristics reviewed is East Natuna Gas Field which has a gas composition of 71% CO2 and 29% methane with modified pressure based on the capability and capacity of available equipment. From the conditions and characteristics of the field, the CO2 method of separation from natural gas using cryogenic distillation was chosen.This research presents analysis and sensitivity of technical parameters that influence the method of CO2 separation from natural gas using cryogenic distillation. The sensitivity is done by changing parameters of pressure and very high feed gas flow rate into the column. In addition, the calculation of the diameter and height of the distillation column using the calculation of the formula and the results of the simulation using commercial process flow software. This study applies a CO2 separation process with cryogenic distillation and the desired product specification of CH 4 is 99%. The design of the equipment was simulated using two distillation columns with operating pressure at the first distillation column of 45 bar and the temperature of 19.19 oF, and for the second distillation column the operating pressure was reduced to 35 bar. The results are for the 8000 MMSCFD flow rate case obtained the first number of columns as many as 16 with the size of 7.4 meters diameter and 17.66 meters high, while the number of second column of 4 with the size of 8 meters diameter and 22.38 meters high. The results presented are still less suitable with the conditions in the East Natuna Gas Field because offshore constrains so need to be studied further for design and other methods in application in the field.","PeriodicalId":382428,"journal":{"name":"Proceedings of the Second International Conference on Science, Engineering and Technology","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":"121936978","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 construction of the bridge is in the area of PT TGI gas pipeline. The construction of this bridge uses a pile foundation whose pile is carried out using a beating method using a hammer. The diameter of this pile is 60 cm with a hammer weight of 5 tons and a height of fall of 2.5 meters. This work method will produce vibrations that affect the condition of the gas pipe. One of the aspects that are affected by vibration is the deformation of the soil around the gas pipe. This soil deformation will affect the position of the gas pipe which, if it forms a fairly large slope, may cause gas pipelines to crack. The method used to determine the effect of vibration from the design of the gas pipeline is to use a vibration meter tool. vibration meter is a sensor device that is placed on the stake and on the ground above the gas pipe so that how much vibration and deformation of the soil can be seen. As a result from the test using vibration meter, it was found that the greater the wave velocity due to the design, the greater the deformation that occurs on the soil.","PeriodicalId":382428,"journal":{"name":"Proceedings of the Second International Conference on Science, Engineering and Technology","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":"131543356","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 Philippines, agriculture has a large share of employment and likewise with the population who depends on it. The increase of agricultural product and income is necessary for the growth of the country’s economic condition. Unfortunately, the insufficiency of technology and the use of traditional methods of farming along with the issues and challenges associated to crops farming greatly affects farmers which results to low yielding of crops. The integration of smart agriculture using the Internet of Things (IoT) is an absolute solution in modernizing the traditional methods of agriculture. This simplifies farming techniques and improves time efficiency, water and fertilizer management, crop monitoring, soil and security management. This paper proposes an IoT framework that address the current issues and challenges associated to high valued crops farming in Alfonso Lista, Ifugao. It integrates two main functions including environment data sensing by a wide variety of sensors and environment factors control with some mechanics driven by smart actuators. This sensors and actuators are used for real-time monitoring, analysis and collection of information about the farm conditions like weather, moisture, temperature, humidity, fertility of soil and level of water. Essential data were gather by means of observation and in-depth interview with Ifugao farmers and employees of Yao Jia Xi Corporation – Alfonso Lista, Ifugao. The developed framework provides holistic foundation in the development of IoT-driven system for high valued crops farming with low cost and easy implementation.","PeriodicalId":382428,"journal":{"name":"Proceedings of the Second International Conference on Science, Engineering and Technology","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":"126268234","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}
