Summary Enhancement of efficiency in rice processing mills can help rural farmers to reduce the cost of rice production. Parboiling‐the hydrothermal treatment of paddy rice, accounts for a significant portion of total rice processing costs and its quality. A rice husk powered gasifier‐based parboiling system is an attractive option for rural rice processing mills but has not been widely adopted due to various constraints. Hence, there is a need for technical and economical analysis on gasifier‐based rice parboiling system to generate information on efficiency improvement and the cost‐effective ways in rice processing industries. This paper presents a techno‐economic evaluation of rice husk powered gasifier‐based rice processing systems working in either Producer Gas in Hot Gas Mode (PG‐HGM) or Producer Gas in Cold Gas Mode (PG‐CGM). MATLAB software has been used for mathematical analysis. The research reveals that the biomass gasifier operated rice parboiling system working in both modes can have the overall system efficiency as 49% to 57% with a lowest payback time of 4‐2 years. Positive Net Present Cost is observed for the capacities above 1.5 tons/batch in PG‐HGM.

“…This stream feeds the DECOMP block, simulated by a RYield reactor, which simulates the decomposition of the unconventional feed into its conventional components (according to the biomass ultimate analysis in Table 2). The product from DECOMP is moved to the RSTOIC block, which simulates the formation of NH3 and H2S through the following reactions: N2 + 1.5 H2 → NH3, (1) H2 + S → H2S, (2) where, fractional conversion for H2S is considered to be equal to 1 and for NH3 equal to 0.5 [37]. Stream S2 out of the RSTOIC block goes into a separator, called SEP, which separates the stream into three sub-streams: VOLATILE, CHAR, and H2SNH3, which are, respectively, the volatile part, the char part, and the stream made of ammonia and hydrogen sulphide.…”

“…So, with the aim to satisfy the continual increase of energy demand, the replacement of the fossil fuels with a renewable and sustainable source is necessary to produce environmentally friendly energy. Nowadays, biomass represents an ideal energy source; in fact, it is widely available and has a very good relationship with the environment [1,2]. The global energy wood supply is estimated to be 0-23 Gm 3 /year (0-165 EJ/year).…”

Biomass Steam Gasification, High-Temperature Gas Cleaning, and SOFC Model: A Parametric Analysis

et al. 2020

Gasification technology is actually one of the most effective ways to produce power and hydrogen from biomass. Solid oxide fuel cells (SOFCs) have proved to be an excellent energy conversion device. They can transform the chemical energy content in the syngas, produced by a gasifier, directly into electrical energy. A steady-state model of a biomass-SOFC was developed using process simulation software, ASPEN Plus (10, AspenTech, Bedford, MA, USA). The objective of this work was to implement a biomass-SOFC system capable of predicting performance under diverse operating conditions. The system is made of a gasification zone, gas cleaning steps, and SOFC. The SOFC modelling was done without external subroutines, unlike most models in the literature, using only the existing ASPEN Plus blocks, making the model simpler and more reliable. The analysis of the syngas composition out of each cleaning step is in accordance with literature data. Then, a sensitivity analysis was carried out on the main parameters. The results indicate that there must be a trade-off between voltage, electrical efficiency, and power with respect to current density and it is preferable to stay at a low steam-to-biomass ratio. The electrical efficiency achieved under the operating conditions is 57%, a high value, making these systems very attractive.

Advanced Evaluation of a Biomass Externally Fired Hydrogen Production Combined Cycle

et al. 2021

Hydrogen is produced by an externally fired combined cycle and can be consumed in different ways. For the present study, both common and realistic thermodynamic and exergoeconomic analyses were applied. With the realistic method, the results are not necessarily in accordance with common analyses. The compressor pressure ratio (rp) and the gas turbine inlet temperature (TIT) are the varying parameters in common analyses. Varying rp identifies optimum energy and exergy efficiencies. With the common exergy analysis, the gasifier and the heat recovery steam generator have low exergy efficiencies, but the modified analysis assigns high exergy efficiencies to them.
