  Sulfur Recovery Unit (SRU): SRU is widely used to recover sulfur-containing, poisonous acidic gas in the oil refinery process. The most commonly applied method in the sulphur recovery unit process is the Claus Process, which burns the incoming gas with oxygen, refrigerates the burnt gas, and recovers sulfur from the burnt gas. SRU claus unit converts sulfur gas such as H2S into elemental sulfur, so as to convert waste into treasure and protect the environment.   Application of SRU: 1. Separate sulfur from sulfur-containing oil 2. Recover the wasted material efficiently 3. This sulphur recovery unit in refinery can reach rather high sulfur purity   Advantages of SRU: 1. Sulphur recovery unit process reduces the pollution of refineries greatly, and it's environmentally friendly.   2. The SRU unit turns H2S into useful material, reduces power consumption, and can bring huge economic benefits.   3. Harmless processing of H2S which was produced during the refining...

 Semi-regenerative Reforming (SRR): With the help of heating, hydrotreating and catalyst, semi-regenerative reforming is a process which is used to convert petroleum refinery naphtha distilled from crude oil (typically having low octane ratings) into high-octane liquid products called reformates, which are premium blending stocks for high-octane gasoline. Compared with other regenerative reforming types, semi-regenerative petroleum reforming has advantages includes  low investment, low operating fee…etc. Semi reforming of petroleum can also be applied in various production scales.     Application of SRR: 1. Widely used in petrochemical industry.   2. In the hydrogenation, heating, high pressure conditions for light gasoline fractions or naphtha can be processed to be re-gasoline.   3. High-octane petrol is produced by using SRR.   4. Large amount of aromatics will also be produced.     Advantages of SRR: 1. The reforming crude oil design ma...

  Fluid catalytic cracking unit (FCC): FCC is one of the most important conversions processes used in oil refinery process. The purpose of FCC unit is to transfer heavy crude oil into light oil. Under the action of heat and catalyst, upgrades the heavier, higher-boiling fractions from the crude oil distillation by converting them into lighter and lower boiling, more valuable products like cracking gas, gasoline and diesel oil etc.   Application of FCC: 1. Many products including ethylene, petrol, diesel, Heavy diesel, slurry oil … etc. could be obtained by using FCC refinery unit.   2. PCC's FCC refinery unit has a high catalytic efficiency.   3. One of the main methods of secondary processing of oil, in the role of high temperature and catalyst to make heavy oil cracking reaction, into crack gas, gasoline, and diesel.   Advantages of FCC: 1. The process of blowing air can make the catalyst regeneration, recycling.   Subsequent reaction heat is provided by...

  PCC's modular 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. As one of the experienced modular oil refinery manufacturers, PCC provides reliable modular solutions that meet global standards.   Depending on the refining capacity, modular crude oil 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 modular refinery cost predictable and competitive. 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 Refineries some components (such as crude distillation columns) are too large to mount on skids and must be shipped sep...

 lng plant process description 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 ethy...

  Heavies Removal Unit (HRU) is used to remove C3+ hydrocarbons from feed gas. As a key hydrocarbon removal step in gas processing, the operation of an 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.
