Although the Oil and Gas industry in North America has enjoyed various exemptions from hazardous waste regulations over the years, these regulations are changing and more emphasis will have to be placed on minimizing wastes from the production of oil and gas. As a result a Waste Minimization Program has been developed for application at Mobil's sour gas plants in Western Canada. The Program consists of a multi-phased approach where the primary focus is on the Waste Audit which is the first step in reducing waste.
The paper will provide an overview of the various phases of the program including the development of the waste flow diagram and the material balance study. Procedures for identifying waste reduction alternatives and ranking criteria will also be discussed as well as suggestions for a cost/benefit analysis and implementation plan. Emphasis on the approach, audit team selection and expectancies from the program will be reviewed.
To date the program has been implemented at five(5) sour gas plants in Western Canada. The paper will present some of the results from the program and outline minimization options that have been implemented with success. The program has already yielded a 30% reduction in solid and liquid wastes at many of these facilities.
