NOx Kårstø. Assessment of increased emissions. NILU OR

Tønnesen, D.; Berglen, T.F.; Svendby, T.

Norwegian Institute for Air Research (NILU) has performed dispersion calculations of emissions to air to quantify the environmental impact of increased emissions from Kårstø gas processing plant, from 775 tonnes/year to 906 tonnes/year. Maximum hourly mean value of NO2 for the Kårstø stacks is 12,8 µg/m3 (back ground 1 µg/m3), this is in compliance with Norwegian threshold values. Regional model calculations using WRF-EMEP show that calculated maximum hourly mean value for NO2 is 59 µg NO2/m3, while maximum daily mean is 19 µg NO2/m3 (all sources included). The contribution from increased emissions (from 775 to 906 tonnes/year) is less than 1% for dry deposition and less than 1¿ for wet deposition, i.e. less than the interannual variation.

Numerical Study of Non-Linear Effects for a Swept Bias Langmuir Probe

Kjølerbakken, Kai Morgan; Miloch, Wojciech Jacek; Martinsen, Ørjan Grøttem; Pabst, Oliver; Røed, Ketil

We present a numerical study disclosing non-linear effects and hysteresis loops for a swept bias Langmuir probe. A full kinetic particle in cell (PIC) model has been used to study the temporal sheath effects and the probe current. Langmuir "close to steady state" condition is required to characterize the plasma. However, during operations above frequencies normally used, capacitive and non-linear resistive effects are being unveiled. We demonstrate how ion and electron density and temperature change properties of the probe-plasma system. We also show that a swept Langmuir probe exhibits essential properties described as the "fingerprint of memristors" and how a Langmuir probe can be identified as a transversal memristor. Understanding non-linear processes might enable new ways to operate Langmuir probes with higher sampling rates and better accuracy.
