This paper investigates opportunities for integration of a Substitute Natural Gas (SNG) process based on thermal gasification lignocellulosic biomass in an industrial plant currently importing natural gas (NG) further processing to speciality chemicals. The assumed SNG configuration is similar that selected the ongoing Gothenburg Biomass Gasification demonstration project (GoBiGas) and modelled Aspen Plus. heat power potentials are investigated using Pinch Analysis tools. Three cases have...
This work investigates the energy performance consequences of replacing conventional natural gas-based syngas production with biomass gasification-based as a supply feedstock for oxo synthesis plant. The investigation is conducted plant currently processing 175 MW [higher heating value (HHV) basis] gas (NG) annually. Two concepts based on same gasification technology are considered: (i) NG biomass-derived synthetic (bio-SNG); (ii) syngas. upon process models established in Aspen Plus order...
Increased utilization of industrial excess heat (or waste heat) can reduce primary energy use and thereby contribute to reaching climate targets. To estimate the potential availability heat, it is necessary capture significant heterogeneity sector. This requires development methodologies based on case study assessments individual plants, adopting a systematic approach consistent assumptions. Since recovery for power generation or off-site delivery competes with internal on-site fuel savings,...
In a wide variety of thermal energy systems, the high integration among components derives from need to correctly exploit all internal heat sources by proper matching with sinks. According what has been suggested in previous works address this problem general way, “basic configuration” can be extracted system flowsheet including but exchangers, order between hot and cold streams through process techniques. It was also shown how comprehension advanced thermodynamic cycles strongly facilitated...
New ambitious targets for reduced greenhouse gas emissions and increased energy efficiency in industry the stationary sector provide incentives industrial plants to investigate opportunities substantially increasing recovery use of excess heat from their operations. This work investigates economic feasibility recovering at a Swedish chemical complex site internal or export regional district heating (DH) network. The is based on investment cost data estimated previous by authors. A site-wide...
The definition of appropriate energy targets for large industrial processes is a difficult task since operability, safety and plant layout aspects represent important limitations to direct process integration. role heat exchange in the sites was studied this work. A computational framework used which allows estimate optimal distribution stream loads different subsystems select size site wide utility system. complex Swedish refinery as case study. Various system aggregations, representing...
In this article, the substitution of a fossil fuel-based hydrogen (H2) production unit with biomass-based process in large European refinery is studied. Pinch Analysis performed and several cases are evaluated terms energy CO2 balances. Integration opportunities yield an increase efficiency from 70 to 79 %. addition H2, maximum 77 t/h HP steam or 21.8 MW electricity can be exported refinery. Maximum potential for reduction emissions amounts 758 kt/y found when H2 coproduced.
The search for increasing performance and efficiency in energy system analysis leads to complex highly integrated systems configurations. In a wide variety of the high integration among components derives from need correctly exploiting all internal heat sources by proper matching with sinks. To address this problem general way, previous works it was suggested extract flowsheet “basic configuration” including different exchangers (named “basic” components) set hot cold thermal flows (without...
