Micro-Climate modification around the Warri Refining and Petrochemical Company, Nigeria

Abstract

Emissions from refineries impact on the micro-climate of the area in which they are situated. The study examined the micro-climate parameters (atmospheric temperature, relative humidity and wind speed) and pollutant concentration (Particulate Matter- PM2.5 μm, and PM10 μm, Carbon monoXide - CO, Volatile Organic Compounds - VOCs, Hydrogen sulphide - H2S, Sulphur dioXide -SO2 and Nitrogen dioXide - NO2) around Warri Refining and Petrochemical Company (WRPC), Nigeria and its environs. The study revealed that pollutant concentration and urbanization process associated with the activities at WRPC influence the micro climate around same. Land Surface Temperature Analysis also revealed the occurrence of a „heat island‟ covering the refinery, including adjoining built-up areas. The study recommends extensive tree planting and use of alternative green energy sources to reduce emissions from refinery activities and fossil fuel use.
