Abstract

Artikel ini merupakan suatu kajian dari hasil-hasil penelitian yang telah dilakukan untuk memurnikan biogas. Kandungn dalam biogas terdapat gas-gas pengotor seperti H2S, CO2, NH3, dan H2O yang apabila tidak dihilangkan dapat mempengaruhi pada proses pembakaran dan menimbulkan kerugian manusia dan lingkungan. Penelitian-penelitian yang telah dilakukan mengenai pemurnian biogas  hanya bertujuan untuk menghilangkan satu atau beberapa komponen gas pengotor secara parsial saja, maka dilakukan kajian ini agar dapat dilakukan penelitian pemurnian biogas secara terintegrasi untuk menghilangkan komponen gas pengotor secara menyeluruh sehingga diperoleh CH4 dengan kemurnian tinggi. Tahapan proses pemurnian  yang dirancangadalah proses kondensasi yang terintegrasi dengan proses adsorpsi menggunakan adsorben karbon aktif dan zeolit, sehingga dihasilkan gas CH4 dengan kemurnian tinggi sebagai biomethane sumber energi terbarukan. Kata kunci: integrasi, adsorpsi, karbon aktif-zeolit, biogas, biomethane

Abstract

This paper deals with one-dimensional dynamic modelling and simulation of deep -bed com drying by two-phase model or heterogeneous model The models consider mass and heat transfer process within grain and drying air phase. This model also considers moisture content and temperature gradient within grain. The coupled of partial differential equations developed, then solves numerically by finite difference with altemating direction implicit method algorithm. The dynamic models predict not only humidity and temperature of outlet drying air, but also grain moisture content and temperature. The simulated profiles are compared with expenmental data, taken from available literature. The models can describe corn grain drying process in deep -bed dryer. However, the model parameters should be modified to get drying characteristic profiles that closed to the experimenal data.
