The Petrochemicals industry: breaking down BTX

While primarily used as energy sources, fossil fuels are often distilled and refined into different substances. These chemicals are then used in the production of everything from plastics to detergents. Benzene, Toluene and Xylene (BTX) make up a mixture commonly used in the petrochemicals industry. BTX is essential for extracting and creating in demand products…

Chemical processing: the role of ethylene glycol

Oil rigs and underwater pipelines must be able to operate in extremely low temperatures, but equipment working in a large body of water must also contend with salt causing corrosion. Damage potential In an inherently hazardous environment, risk mitigation is the difference between a successful oil rig and a large-scale industrial disaster. Offshore oil and…

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…
