In the petrochemical industry, primary petrochemicals, i.e. olefins, aromatics and methanol, serve as precursors or “building blocks” to the production of a vast range of chemical products.
Globally, the largest production
volumes of primary petrochemicals are methanol, ethylene, propylene, butadiene, benzene, toluene and xylenes. Ethylene, propylene and butadiene, along with butylenes, are collectively called olefins, which are unsaturated aliphatic hydrocarbons that contain one or more double bond. Benzene, toluene and xylenes are commonly referred to as aromatics, which are unsaturated cyclic hydrocarbons containing one or more ring structure.
The production of primary petrochemicals requires energy intensive processes. Ethylene production for instance, is the largest energy consumer in the Chemical Industry. Cracked gas produced in the pyrolysis furnaces is compressed and separated to produce ethylene and propylene. The cracked gas compressor (CGC) is one of the largest and most important pieces of equipment found on an ethylene plant. It must operate efficiently and effectively for many years. The target for all ethylene producers is to maximise run length, thereby improving production capacity and operating efficiency.
To achieve plant production capacity and efficiency targets, we work closely with our customers to develop integrated Mechanical, Operational and Chemical solutions for effective control of corrosion, coking, polymer fouling, foaming and emulsions in petrochemical process systems, including:
Dilution Steam Systems
Cracked Gas Compressors
Acid Gas Removal Systems
Light-Ends Fractionation Units
Mixed C4, Mixed C5, and Pyrolysis Gasoline Units
In collaboration with our technology partner, GE Water and Process Technologies, our range of best practice technologies, world-class services and innovative monitoring and control solutions help improve plant integrity and reliability, conserve energy, maximise plant efficiency and boost profitability. Our comprehensive range of treatment technologies for petrochemical plants include:
Filmers: to protect metal surfaces from attack by acidic and corrosive species. The range comprises water-soluble and hydrocarbon-soluble filmers.
Neutralizers: to reduce the concentration of acidic species generated by or inherent to certain processes.
Oxygen Scavengers: to reduce the presence of free oxygen.
Silicone-based Antifoams: to reduce or prevent foam formation in high temperature processes.
Copolymer (propylene oxide / ethylene oxide) and PEG-based Antifoams: to reduce or prevent foaming in processes where Silicon based antifoams are unsuitable.
Inhibitors: to mitigate fouling or to reduce the rate of fouling within processes. The inhibitor range comprises:
Free Radical Inhibitors
Dispersants: to manage fouling within processes by typically preventing foulants from agglomerating and adhering to process equipment. The dispersant range includes water-based and hydrocarbon-based options.
Emulsion Breakers: to manage and dissipate emulsions-forming processes that affect phase separation and process efficiency.
