Gas-to-Liquids, or GTL, is a technology breakthrough to convert natural gas into high-performing, ultra-clean liquid fuels by means of the Fischer-Tropsch (FT) process. This new and emerging technology is expected to contribute a larger share of the world's gas-processing in the future. The overall objective of the paper is to develop an risk-based Environmental Management System (EMS), to assist the gas-processing industries to effectively implement and manage mitigation measures and also to reduce significant environmental risks from GTL industries. This risk based EMS provides information to government agencies, stakeholders, including policy makers, design and process engineers for making reasoned decisions by defining the range of risks associated with various options.
This paper provides systematic approach to address the risks associated with GTL industries which involves impact identification, determination of severity, estimation of impact probability and evaluation of risk significance. The objectives of the paper are a) to develop the framework to assess the risks, b) to provide a qualitative assessment of the risks, in terms of the potential impact on different environmental components, c) to assess the relative significance of the risks and d) to identify and implement additional control measures to manage the environmental risks. Incorporating risk assessment into EMS allows environmental managers to prioritize risks, to identify the resources needed, and to control and manage the identified risk factors. A brief overview on EMS for GTL industries has been provided to address all activities that have been identified to have potentially significant risks on the environment during different scenarios.
