The company has developed a large team of industry managers in the refinery industry. To provide solutions for the client, the company has built-up a unique bank of knowledge pertaining to control and improvements of specific processes, and believes that it will provide the client with more value when compared to ordinary automation companies.
Atmospheric and vacuum distillation is also referred to as a primary crude oil processing process, which is the first process after the crude oil enters the oil refinery.
Catalytic cracking is a type of heavy oil weight reduction process to improve the crude oil processing depth at the refinery. Currently, the catalytic cracking equipment is being developed to become more advanced and economically efficient.
The catalytic cracking equipment mainly comprises: Reaction – regeneration unit, energy recovery unit, fractionation unit, and absorbing stabilisation unit. Additional sections include: Desulfurisation unit for dry gas and liquefied petroleum gas, a sweetening unit for gasoline and liquefied petroleum gas, and other sections.
Delayed coking equipment is for a type of heavy oil thermal processing process, which is a key method for oil refineries to reduce the weight of heavy oil, and improve light oil yield.
For hydrotreating, the raw materials are straight run diesel provided by the atmospheric distillation unit and catalysed diesel provided by the catalytic cracking unit. The new hydrogen is provided by the catalytic reform unit. After hydrotreating to generate diesel, it is sent to the blending tank as a high-quality diesel fuel blending component. The refined naphtha sub-product becomes the raw material for the reforming pretreatment unit.
Catalytic reforming is one of the important secondary processing processes in oil refining. The raw materials are naphtha oil and atmospheric and vacuum oil and gas, and the process produces organic chemical raw materials such as high octane gasoline components and benzene, toluene, and xylene, and also a cheap byproduct which is hydrogen.
