Technology description including background system	The world-wide demand for lower olefins, i.e. ethylene, propylene and butadienes is higher than for any other chemical as they are the primary feedstock for most plastics, polymers and man-made fibres. But lower olefins are only found in very low concentrations in crude oil due to their high reactivity. It is thus necessary to split up longer, saturated hydrocarbons into shorter, unsaturated compounds using the large-scale cracking process. The chemical reaction for the cracking process is a dehydrogenation and can be affected either catalytically or thermally. In the European Union the steam cracking process which thermally induces the reaction accounts for the lion's share of the ethylene, propylene and butadiene production. Due to the rising demand for ethylene and propylene as precursors for the polymer production not only naphtha, but also gas fractions are used as feedstock for steam cracking. In the European Union they play a minor role, whereas in the USA even most crackers use gas feedstock. In the steam cracking process suitable hydrocarbons are heated to temperatures of up to 800 °C or even higher in the presence of steam to crack the modules into the desired products - lower olefins. Only a limited number of international technology contractors licenses the equipment used for crackers. The generic design of the machines is quite similar. Little modifications help to optimize the plant performance according to local conditions. Besides differences in the furnace, pressure and temperature of the fractionation columns and refrigeration systems may also vary or turbo expanders may be in use. Regardless of feedstock or contractor a cracker may be separated into three sections namely pyrolysis, primary fractionation/compression and product fractionation. In the pyrolysis section the hydrocarbon feedstock is preheated and then vaporised with superheated steam before passing into long and narrow tubes arranged in a cracking furnace. The hydrocarbon feedstock is cracked into smaller molecules by controlling residence time, temperature profile and partial pressure. This process is highly endothermic and therefore requires a high energy input. Therefore the tubes of the furnace are heated to 750 - 875 °C by oil or gas fire burners. To reduce the partial pressure of the hydrocarbon mixture and to minimise coke formation high-pressure steam is injected which gives the process the name steam cracking. To quickly quench the product gases to 550 - 650°C and to recover heat for internal use, transfer line exchangers (TLEs) may be used. The primary fractionation and compression section consists of the primary fractionator (naphtha and gas oil feed only), quench tower, gas compressor and gas cleanup facilities. The primary fractionator is used to condense out and fractionate fuel oil streams produced from naphtha and gas oil fed crackers. The gases are de-superheated in the quench tower by a circulating oil or water stream. The circulating oil or water stream is used as a medium level heat source for the rest of the plant. Product gases from the quench tower .are condensed by four or five stages of gas compression. The gas is cooled after each stage and passed through a liquid knock-out drum. Finally, acid gases and carbon dioxide are removed from the cracked gas. The chilling train usually consists of four or five successive stages of chilling, incorporating ethylene and propylene refrigeration as well as an elaborate self-refrigeration system. This produces hydrogen which is used for downstream hydrogenation, hydrotreating of the heavier products or sold as a product. The exact process flow sequence varies according to the feedstock and the design arrangement, but various fractionation towers are used to separate the desired products. This may include a sequence of de-methaniser, followed by a de-ethaniser . Bottoms from the de-ethaniser are directed to the de-propaniser and the de-butaniser. The lighter the feedstock, the fewer fractions need to be separated and the separation system may be constructer simpler. After separation the ethylene still contains undesirable acetylene and ethane. Acetylene is removed either by selective catalytic hydrogenation or by extractive distillation. After separation from ethylene ethane is recycled back to the cracker. Similarly the C3 fraction contains methyl acetylene and propadiene after separation. Selective hydrogenation is used to convert this into propylene and propane prior to separation in a C3 splitter. In the European Union crackers are basically fed with Naphtha and condensates, also called natural gas liquids (NGL). Both sorts of feedstock are very similar mixtures of hydrocarbons. Liquid feedstocks have a high share as they are transported easily. Other important feedstock for crackers in the EU are gas oil, butane, propane, refinery gas and ethane. Ethane mainly comes from North Sea gas fields whereas other feedstock gases come from refineries.

Subsequent review comments

The goal and scope of this Eco-profile study was confirmed to be a European production average of the following polymer precursors: Ethylene, Propylene, Butadiene, Pyrolysis Gasoline, Ethylene Oxide (EO), and Ethylene Glycols (MEG, DEG, TEG). The geographical scope includes the EU 27 member states and Norway, with a coverage of 50 plants (approx. 92% of European production volume). One important limitation of the technological scope is that the study considered only steam cracking, the most important process to produce ethylene and propylene, whereas the Fluid Catalytic Cracking (FCC) process is not included here. This technological scope is in line with earlier Eco-profiles published by PlasticsEurope which were also limited to steam crackers as a source of olefins and their derivatives. Further, since naphtha is the most common feedstock in Europe, the examined population of cracker units comprised predominantly naphtha crackers (only 2 gas crackers, while most units use a mix of feeds). The main data source used for this study was a validated confidential report by the petrochemical industry (APPE) under the European Emission Trading Scheme (ETS) on energy use and CO2 emissions of European steamcracking operations. In addition, publicly available literature was used. Other processes, including refinery, ethylene oxidation, and ethylene glycol production, were derived from a proprietary refinery model (developed by the practitioner IFEU through various petrochemical industry projects), and further literature data. The review confirmed that, despite no primary data collection was conducted, the data used are applicable, up-todate, and modelled with a view to internal consistency. The temporal scope was confirmed to be 2009 reference year and valid at least until 2014 in view of the slow technological changes. The following aspects were subject to particular scrutiny by the review panel: •The product range of the steam cracker, especially the designation as high value compounds (HVC) for the purposes of allocation; •the input/output balance of hydrocarbon feedstocks, also accounting for internal loops or further processing of some intermediate products (such as hydrogen and pyrolysis gas); •specifically, the modelling of non-HVC refinery/fuel gases which are valorised either for thermal energy or for secondary cracking or other post-processing steps – while these will not be burdened with process energy requirements and emissions of the steam cracker itself, they do bear a share of the upstream burdens; •the use of electric and thermal energy, and the consistent accounting for the associated emissions; •the consistent and justifiable use of allocation methods; •plausibility checks of calculations along the productions chains. A review meeting between the LCA practitioner and the reviewers was held, including a model and database review, and spot checks of data and calculations. The results are thus held to be representative and reliable for the specified production routes. It is noteworthy that, compared with previous studies under the PlasticsEurope Ecoprofiles programme, the results for butadiene and pyrolysis gasoline (pygas) have changed notably: •According to recent industry data (APPE), the thermal energy (steam) required for the steam cracking process is rather high compared with the previous version of this Eco-profile. •The previous edition of the Eco-profiles for olefins apparently used a mass allocation for energy demand and emissions of the steam cracking process to all cracker output streams (thus lowering specific burdens), not only to the HVC as in the present version; from today’s perspective, also to ensure consistency with current industry practice (APPE), the latter allocation is deemed more appropriate. •It is noteworthy that fuel-grade by-products which are returned to the refinery (looped back) were calculated with their calorific value and with their upstream burdens (oil extraction, transport and refining), but no process-related environmental impacts were assigned to them. •Specifically, the impact indicators for butadiene have increased substantially because butadiene is extracted in a separate facility following the steam cracker, and this additional processing requires thermal energy, electricity, and solvents. •The impact indicators for pygas (including benzene, toluene and xylene, BTX, and other components) have decreased because of the adjusted allocation. •The overall levels of greenhouse gas emissions of the steam cracker units were confirmed to be in line with APPE’s ETS reporting and corroborated by bottom-up calculations based on the internal use of low-value byproducts as process fuels (mainly methane). For greenhouse gas emissions, the results of this new version of the Eco-profile are hardly higher than those published in the previous version of 2005. •Other impact categories changed somewhat in proportion with the process energy requirements. It should be noted, however, that some indicators apparently changed substantially due to life cycle inventory items in the previous version not being specific enough to allow an accurate a posteriori calculation (average characterisation factors applied to unspecified substance flows). In these cases, a comparison with the previous version is strictly speaking not valid. Further, the review verified that the model and calculations comply with the rules of the PlasticsEurope Ecoprofiles methodology and with ISO 14040–14044: the resulting life cycle inventory datasets for Ethylene, Propylene, Butadiene, Pyrolysis Gasoline, Ethylene Oxide (EO), and Ethylene Glycols (MEG, DEG, TEG) and are thus compatible building blocks for use in other Eco-profile calculations. Review Summary The Eco-profile of Ethylene, Propylene, Butadiene, Pyrolysis Gasoline, Ethylene Oxide (EO), and Ethylene Glycols (MEG, DEG, TEG) has been validated to appropriately represent current European production of these polymer precursors. The underlying emission data for the steam cracking process are consistent with reports of the petrochemical industry under the European Emission Trading Scheme (ETS). Other processes, including refinery, ethylene oxidation, and ethylene glycol production, were derived from project and literature data and modelled with a view to internal consistency. The results are thus held to be representative and reliable for the specified production routes. Reviewer Names and Institutions Chair: Dr.-Ing.
