Abstract

Gasification of biomass can be used to produce fuel gas that could potentially be used as a powersource for the sustainable development. The main aim of this study is to determine the effect of lignin,cellulose, proximate and ultimate of ramie wood chip biomass and shell coffee to produce gas and thepotential for regional electricity generated. Research carried out by the analysis of lignin and cellulose,proximate and ultimate, calorific value, gasification, composition gases and energy potential. From theresearch results, the waste of coffee shells and ramie wood chips were used as a new energy source toproduce syngas by means of the gasification process. The highest lignin content was for 45.10% coffeeshell and the lowest for flax wood chips was 18.26. Meanwhile, the highest cellulose content was hempwood chips 44.82% and the lowest was coffee skin shell 17.93%. The potential energy produced fromgasified gas provides a correlation with levels of lignin and cellulose. The higher the lignin content andthe greater the cellulose content, the higher energy that occurs in the coffee shell shells of 5.78 kW, andvice versa what happens to hemp wood chips with low lignin levels and high cellulose content providesa potential energy of 4. 64 kW

Abstract

Conversion processes that involve large amounts of energy include processes in furnace reformers inthe steel industry. The reformer unit used to convert the process gas, namely a mixture of gas andsteam into CO and H2 gas with the help of a nickel catalyst. The heat energy used in the process is theresult of combustion from natural gas using combustion located above the furnace. The most importantthing in the conversion process is the radiative heat transfer in the combustion chamber to the reactionpipe wall so that enough energy is obtained to carry out the conversion process. One way to determinethe heat distribution of the reformer combustion chamber is to know the temperature profile along thereaction pipe, including the pipe wall temperature, the process gas temperature, and the temperatureof the combustion gas used as energy for the process in the reformer furnace. The performanceevaluation of the reformer furnace uses a mathematical model for combustion in the furnace which canlater be developed by knowing the fitting composition of the conversion results. The type of reformerstudied is the top-fired reformer. The results of modeling using data from the steel industry obtained thehighest temperature from the combustion of gas from the burner which is in the reaction pipe at aposition 3-4 meters from the upper end of the reformer around 1300 oC and the temperature of naturalgas-steam in the pipe reaches 860 oC at the end of the pipe. reaction. The pipe wall heating with naturalo ogas fuels provides a maximum temperature ranging from 890 C - 895 C on the outer wall of thereaction pipe, and the pressure inside the reaction pipe ranges from 8.0-8.5 atm.

Abstract

Indonesia is the largest palm oil producer in the world. 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.
