What is Hgu unit in refinery?

The main Hydrogen Generation Unit (HGU) consists of feed Pre-desulfurisation section, followed by desulfurisation, reforming and process gas cooling with high temperature shift conversion to increase the hydrogen content of the process gas. Purification is done with a Pressure Swing Adsorption unit.

What is refinery capacity?

The capacity of a refinery or process unit is a measure of its maximum throughput. In refining, capacity is typically measured in terms of the volume of the primary liquid feed that goes into the unit, though there are some exceptions (such as alkylation) where product output is the more common measure.

What are the 3 stages of oil and gas?

Oil and gas companies can generally be divided into three segments: upstream, midstream, and downstream. Upstream firms deal primarily with the exploration and initial production stages of the oil and gas industry.

What is CDU VDU in refinery?

Distillation of crude oil is carried out in two units, first in an Atmospheric Distillation Unit (also known as Crude Distillation Unit, CDU), with further processing of the residue from atmospheric distillation in the Vacuum Distillation Unit (VDU), as illustrated in Figure 4.2.

What is VDU in refinery?

About 80\% of the refineries operating in the United States have a vacuum distillation unit (VDU), a secondary processing unit consisting of vacuum distillation columns. To increase the production of high-value petroleum products, these bottoms are run through a vacuum distillation column to further refine them.

What is an ISOM unit?

Also known as: C5/C6 isom. The isomerization unit converts light naphtha into a higher-value gasoline blendstock by changing its molecular shape and raising its octane. The primary product of isomerization is called isomerate. The value from isomerization is its ability to upgrade light naphtha into gasoline.

What is RFCC Refinery?

Residue fluid catalytic cracking (RFCC) is used for upgrading heavy feedstocks to light products such as gasoline.

Which is world’s largest refinery?

Jamnagar Refinery
Jamnagar Refinery, Reliance Industries – India The Jamnagar Refinery, commissioned in July 1999, is a private sector crude oil refinery and the largest refinery in the world, with a capacity of 1.24 million barrels of oil per day. It’s owned by Reliance Industries Limited and is located in Jamnagar, Gujarat, India.

What is a crude unit?

Crude units are the first units that process petroleum in any refinery. There objective is to separate the mixture into several fractions like naphtha, kerosene, diesel and gas oil. A schematic diagram of an atmospheric crude fractionation unit is shown in Figure 1-1.
