Guidelines on flare and vent measurement (Inglês)

This document provides guidance on quantifying flare and vent rates at oil and natural gas facilities. While the focus is primarily on continuous vent and flare systems, guidance is also provided for intermittent systems. Section two presents related information of interest, including a description of the target sources of venting and flaring, information on relevant studies delineating alternatives to venting and flaring, design and operating practices and international regulations. Section three presents key constraints and considerations to be addressed when selecting a continuous flow measurement system for both new and existing flare and vent systems. Recommendations on record keeping and flow verification are also provided. Section four provides a review of measurement techniques that may be used to perform periodic flow tests on vent and flare systems. Section five provides a review of selected estimation techniques which are sometimes used to estimate vent and flare rates. Flare and vent systems exist in essentially all segments of the oil and gas industry and are used for two basic types of waste gas disposal: intermittent and continuous. Intermittent applications may include the disposal of waste volumes from emergency pressure relief episodes, operator initiated or instrumented depressurization events, plant or system upsets, well servicing and testing, pigging events, and routine blowdown of instruments, drip pots and scrubbers. Typically, waste gas volumes are flared if they pose an odor, health or safety concern, and otherwise are vented.
