摘要

本研究评估了通过直接催化甲烷化从沼气中生产合成天然气（SNG）的工厂的技术经济可行性。拟建的设施采用Aspen Plus®v14进行模拟，采用涵盖从沼气预处理到最终产品生产的整个过程的综合方法。该装置旨在为电力到天然气（电力到甲烷）脱碳战略的发展做出贡献。该工厂位于西班牙东北部，以工业规模运营，从1425 Nm3/h的沼气厂获得的天然气生产能力约为1100 Nm3/h。该过程包括五个主要阶段，以满足西班牙电网注气的质量标准：脱硫，使用胺去除硫；电解，用于产生可再生氢；热催化甲烷化，将沼气中的二氧化碳与氢气结合，以增加甲烷的含量；脱水，满足煤制气水分规格；热电联产，旨在联合生产电力和蒸汽，以满足工厂的能源需求。对投资成本（CAPEX）和运营费用（OPEX）进行了详细的分析，确定了影响项目盈利能力的关键因素。经济评估表明，每年的总资本投资为2183万欧元，运营费用近800万欧元。基本情景的盈利门槛估计为91.75欧元/兆瓦时，超过了2023年伊比利亚半岛天然气市场的平均水平（39.11欧元/兆瓦时），突显了当前天然气天然气生产的经济挑战。

Techno-economic assessment of a plant for the upgrading of MSW biogas to synthetic natural gas by thermocatalytic methanation

This study evaluates the techno-economic feasibility of a plant designed to produce synthetic natural gas (SNG) from biogas through direct catalytic methanation. The proposed facility is simulated with Aspen Plus® v14, using a comprehensive approach that covers the entire process, from biogas pretreatment to the production of the final product. The installation aims to contribute to the development of Power-to-Gas (Power-to-Methane) strategy for decarbonization.

The plant, to be located in northeastern Spain, operates at an industrial scale with a production capacity of approximately 1100 Nm³/h of SNG, obtained from a 1425 Nm³/h biogas plant. The process includes five main stages to meet Spanish gas quality standards for grid injection: desulfurization, using amines for sulfur removal; electrolysis, for the generation of renewable hydrogen; thermocatalytic methanation, which combines CO₂ from the biogas with hydrogen to enrich the methane content; dehydration, to meet SNG moisture specifications; and cogeneration, intended for the joint production of electricity and steam to meet the plant's energy demands.

A detailed analysis of investment costs (CAPEX) and operational expenses (OPEX) is conducted, identifying the key factors influencing the project's profitability. The economic assessment indicates a total capital investment of 21.83 M€ and operational expenses nearly 8 M€ annually. The profitability threshold for the base scenario is estimated at 91.75 €/MWh, exceeding the 2023 natural gas market average in the Iberic peninsula (39.11 €/MWh), highlighting the current economic challenges of SNG production.

期刊介绍： Biomass & Bioenergy is an international journal publishing original research papers and short communications, review articles and case studies on biological resources, chemical and biological processes, and biomass products for new renewable sources of energy and materials. The scope of the journal extends to the environmental, management and economic aspects of biomass and bioenergy. Key areas covered by the journal: • Biomass: sources, energy crop production processes, genetic improvements, composition. Please note that research on these biomass subjects must be linked directly to bioenergy generation. • Biological Residues: residues/rests from agricultural production, forestry and plantations (palm, sugar etc), processing industries, and municipal sources (MSW). Papers on the use of biomass residues through innovative processes/technological novelty and/or consideration of feedstock/system sustainability (or unsustainability) are welcomed. However waste treatment processes and pollution control or mitigation which are only tangentially related to bioenergy are not in the scope of the journal, as they are more suited to publications in the environmental arena. Papers that describe conventional waste streams (ie well described in existing literature) that do not empirically address ''new'' added value from the process are not suitable for submission to the journal. • Bioenergy Processes: fermentations, thermochemical conversions, liquid and gaseous fuels, and petrochemical substitutes • Bioenergy Utilization: direct combustion, gasification, electricity production, chemical processes, and by-product remediation • Biomass and the Environment: carbon cycle, the net energy efficiency of bioenergy systems, assessment of sustainability, and biodiversity issues.
