PROJECT DESCRIPTION

The purpose of this study was to evaluate the acoustic impact generated by the installation of new plants in a central for separation of existing petroleum fuels.
The project of extension of the central, called T6, involves the installation of new machines in addition to or in place of the old ones.
The Obi obi plant is located in the Niger Delta in an area of about 630,000 square meters.
The plant operates 24 hours a day.
The torches, always active, which burn the gas resulting from the production process have considerable acoustic emission. The whole area is crossed by pipes, some of which transport gas at different pressures, resulting in different degrees of noise. Other elements of considerable noise are the separation units, coolers and turbochargers.

The regulatory framework consists of:

• Environmental Impact Assessment Decree n. 86 (1992) of Nigeria;
• Guidelines and Standards for Environmental Pollution Control in Nigeria, 1990.

PROJECT CHARACTERISTICS

The study is structured in the following phases:

• Analysis of legal regulations concerning to the case under investigation;
• Analysis and characterization of noise sources present in the area concerned with modeling using of the simulation model Mithra;
• Analysis of the noise of the new noise sources to be placed in the area;
• Analysis of the acoustic impact of new noise sources in the area of Obi Obi plant by distribution of isophonic waves at 1.5m in the plant area.
