  Sulfur Recovery Unit (SRU): SRU is widely used to recover sulfur-containing, poisonous acidic gas in oil refinery process. The most commonly used process in sulfur recovery practice is sru process , which is to burn the incoming gas with oxygen, refrigerate the burnt gas and recover sulfur from the burnt gas. SRU 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 unit can reach rather high sulfur purity Advantages of SRU refinery : 1. SRU reduces the pollution of refineries greatly, and it's environmental friendly. 2. SRU turns H2S into useful material, reduce power consumption, can being huge economic benefits. 3. Harmless processing of H2S which was produced during the refining process. For more information about pcc china   and sru in refinery , please feel free to contact us!

  Crude Oil Distillation Unit 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 whi...   Vacuum Distillation Unit Vacuum Distillation Unit (VDU): further distills the residue oil from the bottom of the crude oil distillation unit. The vacuum distillation is performed at a pressure well below atmospheric pressure.   Diesel Hydrotreating Unit Diesel Hydrotreating Unit (DHT): uses hydrogen to desulfurize the naphtha fraction from the crude oil distillation or other units within the refinery.   Semi-regenerative Reforming Semi-regenerative Reforming (SRR): used to convert petroleum refinery naphtha distilled from crude oil (typically having low octane ratings) into high-octane liquid products called reformates, which a...   Fluid Catalytic Cracking Unit Fluid Catalytic Cracking Unit (FCC): under the action of heat and catalyst, upgrades the heav

  Process Philosophy of Modular Oil Refinery Feedstock will be separated into naphtha, kerosene, straight-run heavy diesel, atmospheric residue oil by ADU. Naphtha from ADU is sent to NHT unit, in which reforming stock is main product. Reforming stock is rectified by Semi Regeneration Reforming (SRR). PMS and LNG are sent to respective tanks as products. And hydrogen can be regenerated by PSA. Atmospheric residue oil is sent to vacuum distillation unit (VDU), vacuum gas oil can be produced. Then it is sent to FCC. The FCC dry gas is sent to Hydrogen Generator with dry gas from ADU. FCC AGO together with kerosene and diesel from ADU are sent to DHT unit. HT AGO will be produced and sent to AGO/Kerosene splitter where DPK and AGO will be produced. DPK and AGO will be sent to respective tanks as products. The sulfur will go into the dry gas, LPG, gasoline and FCC fume and so on. And there is sour waste water produced in the processing. The sour gas and sour waste water should be purified

 A gas plant will also be needed to capture and separate the gas products from the CDU but was not sized, nor priced. Upon completion of the process design, the size and cost of the gas plant will be determined. Air Cooling is used in lieu of water cooling. Heat transfer oil and hot products are used in lieu of steam for reboiling and stripping. If client requests the use of cooling water and steam, the daily requirement will be provided with Schedule A process engineering design. Any changes by Client to feedstock and/or product slate will require the generation of a new technical proposal based upon updated feedstock or product slate. An actual feedstock assay will be required prior to commencement of construction. Scope of Supply of small crude oil refinery for sale The Process Design Package shall consist of the process equipment that will include preliminary and final engineering/design; a petroleum oil refinery with necessary equipment; one-year supply of spare parts and a docume

  Know How and Technology of Hydroskimming Refinery The modular oil refinery's core technology is based on the up to date internal technology from PCC. As we know internal's efficiency influence the unit size and energy consumption. We are the member of FRI(which is non-profit organization founded by most esteemed chemical company like Exxon Mobil, Shell, Dow, etc. And the most authoritative research group in internal field). Our newest patent packing Winpak is widely used in the oil and gas field and win very good reputation from our customers.   Jet guided trapezoidal floating valve(SGTV) SGTV is high-performance float valve tray, researched and developed by Tianjin University, on the basis of absorbing the application of bar float valve, fixed tongue and guided sieve tray experience from domestic and overseas. (Patent no. 00204491.9). The valve plate shape is divided into two kinds of models A and B, absorbed the characteristics of the V type grid, changing the rectangular v

   CNG Compress Unit Rich methane gas meets with rich gas ethane reheated by cooling heat exchanger, this steam of gas flows through the CNG compressor to increase pressure to 25Mpag, CNG product can be obtained.   The compressor skid adopts motor drive, and an ASPRO piston dynamic balance less oil lubrication type compressor. The drive is completely explosion-proof motor, its security level is class 1. Motor is connected to the compressor by belt wheel, and by aligns laser alignment instrument. Natural gas is cooled by the interstage air coolers. Gas collected by the downtime interstage gas collecting device will directly enters to the compressor's input pore at the next start. What ’ s more, there ’ re interstage liquid-gas separators and last stage gas scrubbing device. At compressor downtime, these devices will bring the impurities within the system to the recovery tank by gas flow. All the automatic valve drive is driven by the natural gas in the recovery tank, an external air
