Crude Oil Distillation Unit

Crude Oil Distillation Unit (CDU): cdu in refinery is the first processing unit in virtually all oil refinery plant . 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 heavier, higher-boiling fractions from the crude oil distillation by converting them into lighter and lower boi...

Sulfur Recovery Unit

Sulfur Recovery Unit (SRU): gas refinery process is converts sulfur gas such as H2S into elemental sulfur, so as to convert waste into treasure and protect the environment.and nht unit in refinery.

Isomerization Unit

Isomerization Unit: converts linear molecules such as normal pentane into higher-octane branched molecules for blending into the end-product gasoline. Also used to convert linear normal butane into is...

this is about basic refinery process description ,we can understand clearly oil and gas refinery plant  .

 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.

PCC's crude oil processing plant usually consists of processing units like CDU, VDU, NHT, DHT, SRR, FCC, SRU, and Isomerization unit etc.

 Chemical Equipment Co., Ltd. (referred to as PCC) is a leading EPC contractor in oil & gas fields and has consistently proven itself as the company of choice in designing and manufacturing of modular refinery.
