Core Subject :
Journal of Applied and Engineering Chemistry (JAEC) is an international journal covering all aspects of Chemistry, Chemical Engineering, and Applied Chemistry. The journal publishes original research papers, short communications and review articles. The paper published in this journal implies that the work described has not been, and will not be published elsewhere. The submitted manuscripts are classified into three categories: original paper which presents original works in detail, notes and/or short communications which present novel and/or valuable information and reviews which present a general survey of specialized subject in chemistry and chemical engineering.

Abstract

The adsorption method is very promising in the treatment of the industrial effluent containing hazardous metals because it provides a high absorption capacity. This study aims to separate the chromium ions from artificial wastewater solution through adsorption process using adsorbent mixtures of ‘mahkota dewa’ (Phaleria marcocarpa (Scheff)) and clay or loam soil. The effects of high flow rate and packing were experimentally investigated. The adsorption material was made through drying and mixing. This mixture will be used in the process of adsorption by the column bed. The experimental results showed that the amount of chromium ions are absorbed increases with increasing contact time. Reducing the concentration of chromium ions rapidly occur at regular intervals up to 30-40 minutes. The variation of flow rate indicates that the packing height of 60 cm and a flow rate of 2.32 ml/s the concentration of chromium ions are absorbed by 89.5195%. Keywords: Adsorption, mahkota dewa, clay, chromium

Abstract

This study was aimed to asses technical and economic potential of palm oil residue in south Sumatra taking into account availability, present usage, cost involved and other issues to review the state of art of palm oil residue conversion technology and identify suitable technologies for using in South Sumatra and to identify possible biomass electricity generation and carry techno-economical and environmental analysis of the system. The results show that the potential energy that can be extracted from oil palm solid residue in South Sumatera province taking the efficiency of biomass power generation is about 4.4 PJ/year.It can generate electricity up to 308 GWh/year. The waste water generated was about 1 Million meter cube POME/year. This POME can produce 11,058 m3 methane which is equivalent to 0.4 PJ/year and generate electricity as much as 150 GWh /year.Based on the scenario have been analyzed using GIS software shows that the potential area for 15 MW independent power plant constructions have been identified taking into account availability of feedstock and the maximum allowable distances. Analysis of the financial viability of the projects evaluated using RETScreen. The results for independent power plant showed that the project IRR is lower than the discount rate. However, with the implementation of CER for CDM, the project financialanalysis becomes viable. Moreover, other advantages that can be obtained from these projects are the reduction of GHG emission. Overall, the study clearly indicates the high potential for the generation and use of palm oil residue in South Sumatra.Keywords: Palm Oil residue, power plant, CHP, methane capture, RETScreen, GIS Software
