“…A gas stream enriched in methane and hydrogen that enters the Brayton cycle to produce more power is the main output of this AD system. The gas turbine's exhaust is at high temperature [19,20]; hence, before releasing this hot stream to the atmosphere, its heat is transferred to the HTC reactor. If the gas turbine's exhaust heat is insufficient for the HTC process, excess heat is supplied from the lower stages of the steam turbine of the Rankine cycle.…”

Two of the methods for converting biomass to fuel are hydrothermal carbonization (HTC) and anaerobic digestion (AD). This study is aimed at designing and analyzing two scenarios for bioenergy production from undervalued biomass (sawdust). In one of the scenarios (direct combustion or DC), raw biomass is burned in a combustor to provide the heat that is required by the Rankine cycle to generate electricity. In the other scenario (HTC-AD), the raw biomass first undergoes HTC treatment. While the solid product (hydrochar) is used to produce power by a Rankine cycle, the liquid by-product undergoes an AD process. This results in fuel gas production and it can be used in a Brayton cycle to generate more power. Energy and mass balance analysis of both scenarios were developed for each unit process by using Engineering Equation Solver (EES). The required data were obtained experimentally or from the literature. The performances of the proposed systems were evaluated, and a sensitivity analysis was presented to help in finding the best operational conditions.

“…As of technical bearing, conceive of flare recovery systems encounter numerous technical hurdles owing to following constrictions (Ghorbani, Jafari, & Rahimpour, 2013; Heidari et al, 2016): Technology to be acquired from global vendors: Ever since the recovery system’s knowledge is delivered by international vendors, the company is met with inadequate options for obtaining expertise and maintenance helps. Following installation, the company will depend exclusively on the vendor(s) for incoming maintenances and enquiries in relation to day-to-day operation. Insufficient competence and skill: Notwithstanding the company’s extensive operating record, wide capability and expertise in refinery operations, there is a shortage of skill as witnessed with the operation and technology of flare recovery systems. Inadvertent Hazard and Safety management: In jargons of safety matter, positive pressure at compressor suction should be observed on a real-time basis to avert any air backflow that may trigger a volatile mixture.…”

“…Flaring can be inefficient especially with combustion being affected by ambient winds and several other factors leading to incomplete combustion. It is, therefore, an un-doubtable fact that: ‘flaring is not only squandering the significant quantity of precious energy but also engendering environment by spawning toxic venoms’ (Heidari, Ataei, & Rahdar, 2016; Willyard, 2019).…”

Push for sustainability is evident in areas such as energy generation where the focus has been on finding new deposits to outpace drawdown on existing reserves. Gas flaring is employed by oil and gas industries to burn-off associated gasses from refineries, hydrocarbon processing plants or oil and gas reserve wells. It is one of the most taxing energies and environmental problems challenging the world today. Generally, safety flaring was dubbed as the saviour of process plants and mostly covers for sudden or unplanned plant trips. It is an opportunity to cut greenhouse gases (GHGs) from oil and gas processing plants through flare gas recovery (FGR) process. Oil and gas plants can employ diverse FGR procedures to offset key concerns about the environmental bearing of GHGs emanation most of which necessitating novel apparatus and extraordinary outlay of design and construction. In this study, apart from economic aspects, a real-life case study is extensively analysed to highlight exploration and adoption of optimizing FGR that may be beneficial if flare gas can be recovered, instead of burning. The output of the study may have a significant impact for refineries towards both economic and sustainability towards greening. In a nutshell, this study highlights the efficacy of reducing ‘flare gas system’ towards environment-friendly ‘greening’ aspect as the core of designing.

“…Como um exemplo, para uma mistura média de 1,12 kg/s de gás de flare e 0,756 kg/s de gás natural tratado, o primeiro cenário gera 18,9% a mais de potência que o segundo cenário que gera 37,678 MW, de acordo com a simulação [HEIDARI et al, 2016].…”
