comonomer in production of polyethylene Hydrocarbons with three carbons Hydrocarbons with four carbons A remaining mixture of C4 produced as a by-product of the BD Plant A remaining mixture of C4 produced as a by-product of the TBA Plant Hydrocarbons with five carbons A mixture of C5 and Non Aromatics The total production (including off-specifications products) expressed as
a percentage of nameplate capacity, adjusted for plant debottlenecking, scheduled turnaround and scheduled maintenance during the year
A polymer derived from more than one species of monomer A refining process which breaks down large molecules of oil into smaller molecules. When the process is achieved by applying heat only, it is known as thermal cracking. If a catalyst is used as well, it is known as catalytic cracking. Cracking uses molecular decomposition and recombination to produce a range of more useful base chemicals suitable for motor fuels or petrochemicals

Products that do not meet specifications, which are usually sold at a discount
A straight or branched-chain hydrocarbon with at least one unsaturated carbon-carbon bond. Produced by cracking feedstock from raw materials such as natural gas and crude oil. The main olefins are ethylene and propylene and also include butadiene and derivatives
Chemicals derived from petroleum or natural gas
A polymer derived from polymerisation of ethylene and used to make various plastics such as film, sheet, piping and containers
When certain individual molecules (monomers) come together and link up in a chain-like fashion they form a polymer. The chemical reaction that forms a polymer is called polymerisation
A polymer, derived from polymerisation of olefins
A polymer derived from the polymerisation of propylene and used to make packaging materials, toys, mechanical parts, housewares and synthetic fibres
