Classification by Core Process Function
Oil Drilling and Production Equipment
These are the core equipment in the oil extraction stage, mainly including: drilling equipment, cementing equipment, offshore drilling and workover platforms, well workover equipment, oil production equipment, oilfield special vehicles, and various supporting tools.
Reaction Equipment
These are used to complete the physical and chemical reactions of the media and are the core devices in petrochemical production. They mainly include: reaction vessels, reactors, reaction pots, reaction tanks, synthesis towers, hydrocracking reactors, ethylene cracking furnaces, etc.
Heat Exchange Equipment
These are used to complete the heat exchange between media, realizing heat recovery or temperature control. They mainly include: heat exchangers, radiators, heat exchange units, heat exchangers, heaters, reboilers, coolers, condensers, etc. Common types include plate type, shell and tube type, and casing type.
Separation/Mass Transfer Equipment
These are used to complete processes such as separating media components, balancing fluid pressure, and purifying gases. They mainly include:
Towers: Extraction towers, desulfurization towers, oxidation towers, distillation towers, absorption towers, packed towers, cooling towers, raffinate towers, etc.
Separation and Filtration Equipment: Filters, filter presses, centrifuges, filters, separators, screening and classifying machines, etc.
Refrigeration Equipment
These are used to provide the low-temperature environment required for production. They mainly include: coolers, condensers, chillers, refrigeration compressors, cooling towers, freezers, ice water machines, etc.
