regulatory purposes, the petroleum industry's exploration and production (E&P) sector may be required to estimate and report certain emissions for petroleum production tank batteries currently in service As a consequence, the American Petroleum Institute (API) and GRI jointly supported the development of a comprehensive software package for the estimation of emissions from hydrocarbon production tanks The foundation of the software package, entitled Production Tank Emissions Model (E&P TANK Version 2.0), is based upon rigorous thermodynamic principles or, in some cases, upon kinetic models well accepted by industry and the U.S Environmental Protection Agency (USEPA) This version of E&P TANK uses a 32bit user-friendly graphic interface to complement the established functionalities of the previous version Special attention has been paid to the program interface design, making it user-friendly and easily understandable to those with a basic knowledge of Windows™ Validation of the models in E&P TANK Version 2.0 has been completed with good agreement between model predictions and field data Table of Contents Chapter Introduction Welcome About E&P TANK Version
