  Crude Oil Distillation Unit (CDU): is the first processing unit in virtually all oil refineries. The CDU distills the incoming crude oil into various fractions of different boiling ranges, each of which are then processed further in the other refinery processing units. The cdu unit in refinery   is often referred to as the atmospheric distillation unit because it operates at slightly above atmospheric pressure. The products of cdu in refinery   include gasoline, kerosene, light diesel oil, heavy diesel oil, heavy oil … etc.   Application of cdu refinery : 1. Widely used in oil refinery field. 2. Gasoline, diesel, kerosene can be obtained in this process. 3. The different components are collected and utilized separately.   Advantages of CDU: 1 Advanced manufacturing method and quality 2 CDU equipment are inspected under ASME standard. 3 Professional services, economical price, short delivery time 4 Can ensure the full use of the various components to reduce ene...

  PCC's modular oil refinery   are designed and fabricated in our manufacturing base located in Tianjin, China. As the name implies, all equipment is constructed in modules that are designed to be transported quickly and easily anywhere in the world.   Depending on the refining capacity, Modular Refineries can be designed and constructed with the major part of the work accomplished in our factory in a controlled atmosphere. This greatly improves efficiency and keeps costs low. We do as much of the work in our factory as possible, controlling man hours and material costs through the immediate access afforded by our on-site engineering and design facilities.   For the largest modular refinery   some components (such as crude distillation columns) are too large to mount on skids and must be shipped separately. Before shipping and while still in our factory, we preassemble all of these components directly to the modularized process systems so field assembly is short...

  Process of LNG processing plant After compression, the feed gas is processed by dehydration and heavy hydrocarbon separation units. Please see the attached PFD. Process description is detailed as follows: Feed gas compress unit After measuring, the feed gas flows into the compress unit, and boosts the pressure to 2.4Mpag, pressurized gas flows into the dehydration unit. HDU: Dehydration Unit Remove H2O in the feed gas, output dry gas and control dew point lower than -80 ℃ .   After gas sweetening unit (GSU), next process is dehydration unit (DHU). DHU is used to meet water content in the specification, and it can reduce water to 1ppm. The technology adopted is temperature swing adsorption (TSA).   LQU: Liquefaction Unit Liquefaction technology is based on refrigeration cycles, which takes hot and pretreated feed gas, cools and condenses it to cryogenic temperature into liquid product. Refrigerant is a part of natural gas, R22 and ethylene fluid being continuously recirc...

  Heavy Hydrocarbon Removal   Unit Heavies Removal Unit (HRU) is used to remove C3+ hydrocarbons from feed gas. The operation of a HRU is based on the deep refrigeration provided by vapor ethylene to produce reflux to NGL recovery columns.   The process includes direct heat exchange process, NGL/LNG integrating process, and freezing process. HRU can be operated with or without liquefaction unit.   HSU -- Heavies Separation Unit Heavies Separation Unit (HSU) is installed in conjunction with HRU. Once NGL has been removed from the natural gas stream, it must be fractioned into base components, which can be sold as C3 LPG and C4+ hydrocarbons products.   For more information about pcc china , please feel free to contact us!

  PCC has proven track record of providing comprehensive gas utilization solutions for onshore and offshore projects. Such solutions often ensure the implementation of innovative technologies packaged with global project management and execution expertise.   A natural modular gas plants   is required for most gas streams that are produced from a gas well or an associated oil well. Natural gas in its raw form can contain water, NGL (Natural Gas Liquids), CO2 and H2S.   The natural gas from well heads usually requires processing to remove these contaminates from the gas stream. Gas streams from refinery or other processes require gas processing as well to remove liquids and condition the gas stream for its optimum purpose.   We provide gas plant design , natural gas processing plant design , gas processing unit , etc. For more information about pcc china , please feel free to contact us!

  Heli   Pak  is a particle type packing and can be "poured" into any laboratory or pilot scale column. Easily removed for replacement or cleaning.   Special Features of DISTILLATION COLUMN EXPERIMENTAL PACKING: LOW H.E.T.P. - Lowest reported for random packings. HIGH EFFICIENCY - Holdup per plate for a given distilling rate gives high efficiency and optimum all around performance.   NON-CHANNELING - Furnished in larger column diameter because of its capillary liquid redistributing action.   POURS EASILY - Maximum effectiveness requires no laborious or critical filling techniques. LOW COST - Economical to use on a per plate and per distillation basis.   Available in Three Sizes SIZE "B" - 2.5 x 3.5 x 2.5mm - A larger size packing with high capacity and low pressure drop.   Specially designed for use in columns 25mm I.D. and larger.
