Heavy Hydrocarbon Removal Unit

 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.

Processing Units Of Oil Refinery

Image
Oil refining processes are the chemical engineering processes and other facilities used in petroleum refineries (also referred to as oil refineries) to transform crude oil into useful products such as liquefied petroleum gas (LPG), gasoline or petrol, kerosene, jet fuel, diesel oil and fuel oils. Processing Units of PCC Oil Refinery PCC's oil refinery usually consists of processing units like CDU, VDU, NHT, DHT, SRR, FCC, SRU, and Isomerization unit etc. 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 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

  CNG Plant CNG Compress Unit Rich methane gas meets with rich gas ethane reheated by cooling heat exchanger, this steam of gas flows through the CNG processing compressor to increase pressure   to 25Mpag, CNG process   product can be obtained.   OVERVIEW 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
