  OVERVIEW Process of lng liquefaction 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 continuous...

  OVERVIEW Complete Flow Chart of a Flare Gas Recovery Unit 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 plant  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 dr...

  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 gas processing plant  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.   LNG PLANT This unit is applicable to wellhead natural gas pretreatment, including dehydration, hydrocarbon rec...

  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   U nit in R efinery : 1. Many products including ethylene, petrol, diesel, Heavy diesel, slurry oil… etc. could be obtained by using FCC  oil refinery  unit.   2. PCC's FCC oil refinery catalyst  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 regen...

  DHT  refinery : uses hydrogen to desulfurize the naphtha fraction from the crude oil distillation or other units within the refinery. As a key system in the diesel hydrotreating process in refinery , DHT plays an essential role in improving fuel quality and environmental performance. This refinery equipment ensures cleaner diesel production in the oil and gas refinery process.   Application of DHT: 1. Remove impurities and polluted elements from diesel fraction with a high efficiency, making it a crucial component similar to a diesel hydrotreater used in modern refineries.   2. PCC's DHT can increase the performance of diesel product   3. The production process of diesel can be more environmental friendly by using our unit.   Advantages of DHT: 1. The energy consumption of PCC's DHT product is very low   2. The price of PCC's DHT product is economical   If you want to know more about diesel hydrotreating unit process , please visit our website. ...

  A tmospheric crude 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 is often referred to as the atmospheric distillation unit because it operates at slightly above atmospheric pressure. The products of CDU include gasoline, kerosene, light diesel oil, heavy diesel oil, heavy oil…etc.   Application of CDU: 1. Widely used in oil refinery field.   2. Gasoline, diesel, kerosene can be obtained through the integrated CDU VDU in oil refinery 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 The integrated CDU VDU in ref...
