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 surveyAnalysis of the sectoral processesData collectionDetermination of feasible strategies

Within WP 2, the followings are expected to be carried out:Sectoral surveyAnalysis of the sectoral processesData collectionDetermination 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.

Work Package 2

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.

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:

Analysis of the Sectoral Processes

Raw Material Extraction Phase

Production Phase

End-of-Life Phase

Product Waste

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.

Analysis of the Sectoral Processes

Rafinery Operations

Steam Cracking

for Ethylene

Gas Processing

Electrolysis for Chlorine

Ethylene Dichlorine

(EDC)Vinyl Chloride

Production Polymerization

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

Data Collection Boundaries

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

Polymerization VCM PVC

Data Collection – Product Flow

Data Collection – Elementary and Intermediate Flows

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 Collection

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

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.
