Abstract

Pyrolysis which is also called thermolysis will chemically decompose organic matter (biomass) through a heating process without or little O2 or other reagents, where the raw material will undergo a breakdown of the chemical structure into a gas phase. The purpose of this study is as an alternative solution in answering the problem of fuel scarcity in everyday life, & Knowing the amount of activation energy calculated using the Flynn Wall Ozawa method. The biomass used is Dutch teak sawdust obtained from the wood furniture industry in the Tangerang area.The experimental results of pyrolysis of Dutch teak sawdust with round gas opening from experiment 1 to experiment 9 obtained BCO as much as 6.00%, 6.50%, 6.83%, 7.33%, 7.67%, 8 ,83%, 10.17%, 14.33%,16.33%. . While the results of the round gas opening experiment from experiment 1 to experiment 9, BCO was obtained as much as5.67%, 6.17%, 6.67%, 7.17%, 7.33%, 7.83%, 9.67%, 13.83%, 15.83%. The pyrolysis process produces three types of products, namely solid products or charcoal, liquid products (bio-oil) & gas. In our research, the best quality bio oil obtained at temperatures from 548 K to 598 K. The results of bio The oil obtained at this temperature is brownish yellow in color, with an average volume of ± 48 g of bio oil (52.6 ml).

Abstract

Advances in science and technology of human civilization have encouraged industry in Indonesia to develop more and more advanced from simple technology to advanced technology. Chemical industrial technology is the use of engineering science that studies the processing of raw goods into more useful and economical goods which involve chemical reactions in the process. One of them is the technology to evaluate the Heat Echanger in the Chemical Industry, especially in the Oil and Gas Industry, Evaluation of the Heat Exchanger-05 to determine the fouling factor in the oil processing process so that if you know the fouling factor, the Heat Exchanger will be able to know what maintenance needs to be applied. equipment or not. Observing the process of making crude oil into products, diesel, residue and pertasol. From the calculation results, it is stated that the ratio of actual Rd and theoretical Rd is greater than the actual Rd than the theoretical Rd. The actual Rd is 0.02318648 The actual Rd value that can be obtained indicates that there is a buildup of fouling (crust) on the HE-05. The buildup of fouling can inhibit the rate of heat transfer between the residue and crude oil. In addition, this buildup of fouling can produce a hot slot area which can result in leaks in the heat exchanger. the heat given to the residue is 1919948,193 Btu/hour while the heat received by crude oil is 1682707,817 so it can be interpreted that not all the heat given by the residue is received by the crude oil. There is heat wasted by 14%. because it is necessary to add an insulator so that the HE performance is more efficient.
