Oil and gas operators are always in need of handy, desk top tools for quick air emission calculations. In response to this need, HY-BON offers, this valuable Excel spreadsheet for vent gas for free.  Field operations speak in terms of volume of gas in standard cubic feet (SCF) and environmental reporting wants mass amounts of air emissions. Conversion from volume of vent ed natural gas to mass is often needed by companies for internal communications and environmental reporting. Also, when sizin… HY-BON VOC Calculator Spreadsheet - Free Giveaway

Ten things to know about vapor recovery system selection for an oil and gas production facility’s vent gas include the following.          HY-BON VRUs powered by a natural gas engine and an electic motor.  1. Volume of gas to be recovered The gas to be recovered can be referred to as the suction gas to the VRU. This includes data on the cyclical flowrate of the suction gas (i.e., minimum, maximum and average flowrate). When possible, this is best determined using direct measurement.   2. C… Ten Things to Know for Vapor Recovery System Selection

Need reasons to reduce methane emissions now?  We are all focused on something. Focus on chasing down ways to further reduce methane emissions now.    Consider these reasons to reduce methane emissions:  Methane (a major component of natural gas) is product and capturing it and sending it to sales increases profits. Since methane is now a regulated greenhouse gas air pollutant, expect that one day state agencies or the federal government will assess fees on methane emissions based on an… 10 Reasons to Reduce Methane Emissions Now

Beliefs are very strong and control our world. Some beliefs should be questioned with time to help ensure we are on the right track. Beliefs about vent gas from oil and gas production facilities is one area to question beliefs. Storage tanks storing crude oil, condensate and produced water can result in the following "non-beneficial" effects: Loss of hydrocarbon product Increase in air emissions Decreased profitability Additional environmental risks Less favorable public image Ve… Question Your Beliefs About Vent Gas

(Updated November 13, 2019)   People often ask, how do I convert a volume (e.g., standard cubic feet) of natural gas to pounds (mass) and pounds of natural gas to volume? This is important in communications and reports involving vent gas, VOC emissions and vapor recovery units. Below are some equations and examples to use with a more detailed explanation later in this blog topic. Conversion of natural gas volume to weight (mass) requires the volume of gas in standard cubic feet and the mole… Convert Vent Gas Volume to Mass and Mass to Volume

Vent Gas Management for Quad O Compliance With the implementation of the EPA NSPS OOOO (Quad O) rules requiring oil and gas (O&G) facilities to reduce volatile organic compounds (VOCs) and methane emissions from storage tanks, it is critical to take a systematic approach to  Vent Gas Management (VGM). Staying in compliance can be challenging with the alphabet soup of regulations.  Some components of a VGM system for compliance on an ongoing basis for are listed below.  Elements of an Op… Vent Gas Management and NSPS Quad O
