Chemical processing: what is ethylene?

Excess natural gas produced at oil wells is often flared, but it can also be transformed into pipeline quality dry natural gas. This involves a complex industrial process where raw natural gas is cleaned to separate impurities, various non-methane hydrocarbons and fluids. By-products of this process include: ethane, propane, butanes, pentanes and several other compounds.…

Feeling the pressure: process upsets in flaring

45 per cent of oil and gas megaprojects suffer extended project shutdowns into their second year of production. Referring to large-scale, complex ventures that typically cost billions of dollars, megaprojects demand strict budget constraints and complete operational efficiency. Equipment failure could cause an entire shutdown of a project and result in operators missing production uptime…

Knockout drums: removing liquid

The World Bank recently revealed 141 billion cubic metres (bcm) of natural gas was flared in 2017. The figures reflect the global change in attitude towards routine flaring and its reduction, with Russia actioning the biggest decline last year and Nigeria now actively pursuing new regulations to restrict flaring. Operators are also making moves to…

Flaring: efficiency in action

Despite global oil production increasing by a half per cent, recent data from the World Bank revealed global gas flaring is in decline. Operators are becoming more conscious of the gas they are flaring and are willing to better utilise excess natural gas. While flaring is decreasing, the data does not indicate whether the flaring…

The heat is on: flaring in the chemicals industry

Central to our modern economy, the chemicals industry is responsible for converting raw materials (such as oil, natural gas, air, water, metals and minerals) into more than 70,000 different products. Like the drilling of wells for hydrocarbons, processes in refineries and chemical plants inevitably result in flaring to burn gas. Identifying the cause Flaring is performed in the chemicals industry for a range of…

Flaring in America’s busiest oil field

Shale drillers in Texas’ Permian Basin are flaring $1 million worth of natural gas every day, according to statistics published in the Wall Street Journal. The Permian Basin is the largest petroleum-producing basin in the US, pumping close to two million barrels of oil per day. Recent advances in hydrocarbon recovery – such as horizontal…

An IoT framework for gas measurement

This article first appeared in Sensors Online on March 10, 2017 The Internet of Things (IoT) is changing the capability of businesses to measure and manage a range of previously standalone infrastructure. In flare-gas operations, businesses are deploying this capability to monitor flaring volumes remotely and seeing transformative results in terms of cost reduction, emissions…
