Water imbalance for treatment of water discharge from petroleum extraction

Written on: 14.02.2019#1

The following datasets seem to have a water imbalance:

- treatment of water discharge from petroleum extraction, offshore, GLO

- treatment of water discharge from petroleum/natural gas extraction, onshore

They both have a reference product of -1 kg wastewater (i.e. there is 1kg of water input for treatment) and have 0,001m3 of water to environment. If that were all, it would be balanced like all other wastewater treatment datasets.

However, the datasets have an additional input of 0.001m3 of Water, salt, sole.

Hence, we have 2kg in, 1kg out.

Dear Pascal, Thank you for your thread. We will have a look in the case you are reporting and the original documentation of the datasets.Best regards,Avraam Symeonidis,Data analyst, ecoinvent

Dear all

We updated of life cycle inventory data for crude oil, natural gas and mineral oil products. The data and reports are now published on http://esu-services.ch/data/public-lci-reports/. We could also offer additional services for application of the data. Please let me know if you would be interested in such additional services.

Introduction

 

The present data for crude oil and mineral oil products in the KBOB database (KBOB v2.2: 2016) were last updated for ecoinvent v1.0 (Jungbluth 2004) and only small corrections have been made for v2.0 (Jungbluth 2007). Thus, most of the relevant data are more than 15 years old. A relevant part of the information also dates back to the former “Ökoinventare von Energiesystemen” (Frischknecht et al. 1996).

 

Methodology

 

In 2018 a project was finished to update the LCI for mineral oil. Information was gathered from literature, statistics, online company reports and interviews with experts. The following stages are included in the update according to their importance for the Swiss market:

 

·         Crude oil (and joint natural gas) extraction in different countries (Meili & Jungbluth 2018)

 

·         Transport of crude oil to refineries including the import mixes for Switzerland and Europe (Meili et al. 2018)

 

·         Refining of crude oil to crude oil products (Jungbluth et al. 2018a)

 

·         Distribution of mineral oil products to the Swiss and European market including blending with biofuels (Jungbluth & Meili 2018)

 

·         Heating with fuel oils (Jungbluth et al. 2018b)

 

 

 

Updates

 

More than 140 datasets have been updated and revised during the project. The major changes are summarized below:

 

The market situation for crude oil supplies to Europe and Switzerland was updated and new inventories have been developed for extraction in some countries. Most relevant for the update are the direct energy uses and emissions during oil extraction including drilling, venting and flaring. Air emissions due to ozone depleting substances have been re-evaluated. Other important aspects are e.g. the use and disposal of water. With the new data emissions of methane are considerably higher.

 

Transport distances for transport of crude oil to Swiss and European refineries have been reviewed.

 

For refineries the internal energy consumption is most relevant. Data sets on emissions from the incineration of different fuels were updated as well. The other most important aspect is the use of crude oil in the refinery. To support an easy update of the life cycle inventory data investigated here for refineries, the supply mix of crude oil is now modelled in a separate dataset which can easily be changed without changing the data for each single refinery product or the whole refinery directly. Furthermore, the allocation for this input has been revised and is now based on the energy content of products instead of mass.

 

For datasets dealing with the distribution of mineral oil products, updates have been made concerning the share of products imported to Switzerland and the associated transports. Furthermore, an update for the fugitive air emissions has been made. Another crucial point is the consideration of blending of fossil fuels with biofuels according to the present situation on the market.

 

Emission factors for the main air pollutants and the efficiency could be updated for the LCI of oil heating. No newer data were found for the specific NMVOC profile, but the total emission factor was updated. This shows the trend to investigate and publish only data for the main air pollutants, but not for an extensive list of specific substances.

 

Publication

 

All reports, the validation report and data in XML format are published on http://esu-services.ch/data/public-lci-reports/. The unit process raw data can be downloaded and imported into any LCA software capable of reading EcoSpold v1 format. The data have been imported into the KBOB 2016 database and are available as a library for SimaPro.
