Application of space-charge electrostatic precipitator for collection of oil mist from pyrolysis gases

A novel electrostatic precipitator CAROLA® is developed for collection of fine oil mists. It operates on the principle of unipolar particle charging in the corona discharge and particle precipitation under the field of space charge. The pilot precipitator was tested at different gas temperatures. It is shown that the increase of gas temperature changes the characteristics of the corona discharge and particle size distribution, especially for droplets sub-micron droplets. The CAROLA® precipitator was used for collection of oil mist from pyrolysis gases at the HALOCLEAN® plant. The flow rate of biomass in the HALOCLEAN® plant was 15-30 kg/h. The particle mass concentration in the raw gas was over 100 g/Nm. The operation voltage of the precipitator was 10-12 kV and corona current up to 0,1 mA. Single stage electrostatic precipitator ensured mass collection efficiency 97-99,5% for pyrolysis oil mist.

An empirical investigation of host country national categorization of expatriates in the United Kingdom

In recent times, some authors have argued that Host Country National (HCN) categorization of expatriate co-workers plays a major role in expatriate adjustment. Previous studies have argued that HCN categorization of expatriates maybe be based on gender, or national origin. In this study, using data from 331 HCNs in the U.K., we find that HCN expectations of foreigners may play a big role in categorization. Further, we find that categorization leads to lower levels of support offered by HCNs, which can affect expatriate adjustment. We discuss implications and offer suggestions for future research.

Two-nation study of host country national categorization of female expatriates - United States and India

This study was designed to study the role of Host Country National categorizationof female expatriate co-workers, in two samples – U.S., and India. Using data from 54participants in the U.S. and 52 participants in India, we found that respondents from Indiacategorized potential expatriate co-workers from the U.S. into in-group or out-groupsignificantly more than respondents from the U.S. Further, we found that femaleexpatriates from the U.S. are preferred by Indian HCNs as co-workers significantly morethan male expatriates from the U.S. We discuss implications for organizations and offersuggestions for future research.
