“…Where large concentrations of biomass feedstock exist, it may be cost-effective to gasify the biomass close to its source and then build a network of syngas pipelines [19]. It could be argued that national gas grids used to carry a form of syngas before they were converted to carry natural gas instead in the 1970s.…”

“…Because biomass molecules contain oxygen within their structure, biomass-derived syngas often needs to have its H 2 to CO ratio boosted. One option for achieving this is to react some of the syngas with steam over a catalyst to produce H 2 and CO 2 in the water -gas shift reaction [19], accepting a CO 2 removal cost unless there is a by-product H 2 source readily available.…”

“…There is little evidence of this happening at the moment, but the relevant issues are being explored in analogous discussions about creating new CO 2 pipelines to carry captured CO 2 from large point sources to one or more geological storage locations [56][57][58][59]. The issues that need to be dealt with relate to defining an entry specification for gas into a shared network, deciding how to fund an oversized pipeline network that can handle higher throughputs in future, agreeing how early users and later users pay for access in a way that provides equitable reward to those who invested the capital, and finding a workable approach to securing access rights over land owned by multiple parties along with the relevant planning approvals [19].…”

“…A major attraction of syngas is the very wide range of potential uses [19]. Broadly speaking, there are four options for converting syngas into useful downstream products: Fischer -Tropsch synthesis of hydrocarbon chains, methanol synthesis, mixed alcohol synthesis and syngas fermentation [14].…”

The world's increasingly voracious appetite for fossil fuels is driven by fast-growing populations and ever-rising aspirations for the lifestyles and standard of living exemplified in the developed world. Forecasts for higher electricity consumption, more comfortable living environments (via heating or cooling) and greater demand for transport fuels are well known. Similar growth in demand is projected for petrochemical-based products in the form of man-made fibres for clothing, ubiquitous plastic artefacts, cosmetics, etc. All drawing upon the same finite oil, gas and coal feedstocks. Biomass can, in principle, substitute for all of these feedstocks. Although ultimately finite, biomass resources can be expanded and renewed if this is a societal priority. This paper examines the projected growth of an energy-intensive international petrochemicals industry, considers its demand for both utilities and feedstocks, and considers the extent to which biomass can substitute for fossil fuels. The scope of this study includes biomass component extraction, direct chemical conversion, thermochemical conversion and biochemical conversion. Noting that the petrochemicals industry consumes around 10 per cent of the world's fossil fuels as feedstocks and almost as much again in utilities, various strategies for addressing future demand are considered. The need for long-term infrastructure and logistics planning is highlighted.

A Shortcut Approach to the Multi-scale Atomic Targeting and Design of C–H–O Symbiosis Networks

Eco-industrial parks "EIPs" are aimed at integrating natural resources among different participating plants. A particularly important category of EIPs involves hydrocarbon processes where intermediate species and environmental discharges may be exchanged and/or transformed to other chemical species so as to reduce the purchase of fresh raw materials and the disposal of wastes. The problem of synthesizing carbonhydrogen-oxygen symbiosis networks (CHOSYNs) has been recently introduced along with a mathematical programming approach for the optimal design (Noureldin and El-Halwagi 2015). In this paper, a shortcut approach is developed to solve the problem of CHOSYN synthesis. Multi-scale atomic targeting is used to establish benchmarks for the carbon, hydrogen, and oxygen atoms, for the external chemical species to be purchased and discharged, and for the chemical reactions transforming the involved compounds into value-added feedstocks, intermediates, and products. Because of the algebraic nature of the devised approach, it can be readily used by process engineers and can also be used as a starting point for the mathematical programming techniques. A case study is solved in details to illustrate the implementation of the proposed approach.

Synthesis of C‐H‐O Symbiosis Networks

The concept of synthesizing carbon, hydrogen, and oxygen (C‐H‐O) SYmbiosis Networks (CHOSYNs) for the design of eco‐industrial parks is introduced. Within a CHOSYN, compounds containing C‐H‐O are exchanged, converted, separated, mixed, and allocated. The use of C‐H‐O as the basis for integration creates numerous opportunities for synergism because C, H, and O are the primary building blocks for many industrial compounds that can be exchanged and integrated. A particularly attractive feature of the CHOSYN framework is its ability to use atomic‐based targets to establish benchmarks for the design of macroscopic systems involving multiple processes. Several structural representations, benchmarking, and optimization formulations are developed to embed potential CHOSYN configurations of interest and to synthesize cost‐effective networks. A case study with several scenarios is solved to demonstrate the new concept and tools. © 2015 American Institute of Chemical Engineers AIChE J, 61: 1242–1262, 2015
