EPESUS MEETING • No: ECO/08/239001/S12.539401 GülçinKesercioğlu Environmental Eng. Ekodenge Eng. & Cons.
Work Package 2 • This presentation is accounts for, • the developments within the Work Package 2 of the EPESUS project. • Within WP 2, the followings are expected to be carried out: • Sectoral survey • Analysis of the sectoral processes • Data collection • Determination of feasible strategies
Work Package 2 • Within WP 2, the followings are expected to be carried out: • Sectoral survey • Analysis of the sectoral processes • Data collection • Determination of feasible strategies • Sectoral studies will be examined in the exploitation report in the following workshops • Feasible strategies will be developed due to the analysis of sectoral processes and collected data.
Analysis of the Sectoral Processes • The sectors are examined within limited number of sub-sectoral production processes. • within polymer sector just four polymer production will be selected among many other polymer • i.e. PVC, PET, HDPE and LDPE production will be examined within EPESUS • It is expected from the partners to determine four sub-sectoral production. • It is expected from the partners to give more information about the process technical definition.
Analysis of the Sectoral Processes • The sub-sectors are examined via their production processes. • Production processes are demonstrated via ‘flow diagrams’ • In general, the flow diagrams are demonstrated in three phases: Raw Material Extraction Phase Production Phase End-of-Life Phase Product Waste
Analysis of the Sectoral Processes • In detail, the phases can be demonstrated as gate-to-gate: Production phase Raw material phase • It is expected from the partners to define the gate – to – gate system boundaries for the chosen sub-sector. Steam Cracking for Ethylene Rafinery Operations Polymerization Ethylene Dichlorine (EDC) Vinyl Chloride Production Gas Processing Electrolysis for Chlorine
Data Collection • Input and output of the process is the raw materials, energy, chemicals, water, as inputs and waste, waste water, product, by-product as outputs. • This step is asserted as key step since there is a lack of data and the success of the research depends mostly on the conceivable and available process data. • The data is examined within two boundaries: • Gate to gate data • Cradle to gate data
Data Collection • Input and output flow of the processes: • Product flows (i.e. goods and services both as "product" of a process and as input/consumables) that link the analysed process with other processes, • Elementary and intermediate flows (such as resources and emissions but also other interventions with the ecosphere such as land use), • Waste flows (both wastewater and solid/liquid wastes) that need to be linked with waste management processes to ensure a complete modelling of the related efforts and environmental impacts • Product flows that is relevant with the functional unit • It is expected from the partners to define the input and outputs for the defined gate – to – gate boundaries.
Data Collection – Product Flow Polymerization PVC VCM
Data Collection – Elementary and • Intermediate Flows
Data Collection • Several databases are investigated as well as the literature search. • These databases are especially specialized on LCA: • Ecoinvent • US NREL • CPM SPINE, etc. • It is expected from the partners to search the defined database for the defined boundaries. • Defined system boundaries should be changed in case there is not enough data on that boundary.
Data Bases • The databases use the techniques of life-cycle inventory (LCI), consistent with the method of life-cycle assessment (LCA) • In addition to LCA databases more information can be reached from the emission inventories specific to the sector. These are: • US EPA AP 42 Air Emission factors • Database on Greenhouse Gas Emissions (IPCC) • Australia National Pollution Inventory Emission Estimation Techniques • IFC Environmental Safety and Health Guidelines, etc.
EPESUS Library Content • Index of the sectors • Info card • Goal of the study • Scope of the study • Data info • Source info • Process technical definition • Process diagrams • It is expected from the partners to fill the info cards according to the data gather and summit together with process technical definition and process diagrams.
