Process Fixed Equipment

Fixed Equipment or static equipment, referring to  non-moving equipment in the oil and gas and petrochemical industries. There are mainly process equipment. The famous ones are: “pressure vessels, knockout drums, heat exchangers, storage tanks, etc. FDAN Equipment & Engineering Supply, backboned with its Expert Engineering Team long history in design and engineering, generating process and mechanical documents, and manufacture and commission these fix equipment. We understand process requirement and demand of the process licensor and we offer our solutions tailormade to minimize energy consumption and maximum efficiency. Our target is to meet your technical requirements along with investment restrictions by offering the latest engineering practices.



Pressure Vessels (Vertical, Horizontal)

We design, engineer and manufacture pressure vessels according to EN 13445, ASME Boiler & Pressure Vessel Code (BPVC) Section VIII, BS 5500, AD Merkblätter in different applications.

We Quote, design and fabricate more efficient with the leading ASME pressure vessel software’s like PV-Elite or COMPRESS, which save Engineering time, prevents mistakes, and helps more organize MTO’ ordering, shorten equipment delivery times. It combines comprehensive ASME® calculations with cost estimating, solid modeling, and automatic drawing generation.


Heat Exchanger

FDAN offers design, engineering and manufacturing wide range of heat exchanger as follow:

  • Shell and tube heat exchangers.
  • Double pipe heat exchangers.
  • Plate heat exchangers.

According to ASME TEMA.


Storage Tanks

We design, engineer and commission Oil storage tanks, some with capacities of more than 390,000 barrels (more than 16 million gallons), to store crude oil, intermediate stocks (partially refined), finished products, and chemicals.

  • Fixed-roof tanks.
  • External floating roof tanks.
  • Internal floating roof tanks.
  • Domed external floating roof tanks.
  • Horizontal tanks.
  • Pressure tanks.
  • Variable vapor space tanks.
  • LNG (Liquefied Natural Gas) tanks.


Filtration Equipment

FDAN provides design, engineering and manufactures Filters which are used in just about every process equipment package within the oil, gas and petrochemical industry. Their function is to remove impurities in different process systems such as fuel gas, glycol dehydration units or glycol dehydrators, oil lubrication, and even the main inlet gas feed to a gas plant or compressor station.


Dry Gas Filter

We design, engineer and manufacture dry gas Filters which are mainly used to remove the remaining solid particles in gas pipelines (solid particles) especially in reducing pressure stations or compressor stations. The internals called “dry filter element” can be designed in different dimensions and aspects, considering the defined life cycle, and service interval,  and can be replaced accordingly.


Filter Separators

FDAN designs and produces filter separators to separate solids and liquids from flow of (natural) gas. Specifically, to remove impurities such as pipe scale, water, iron sulfide, liquid hydrocarbons, compressor lube oil and sulfur products from the natural gas flow in pipeline.

  • Flexible designs
  • Custom sized vessels and internals
  • Built according to ASME code


Gas Scrubber

We design, engineer and manufacture Gas Scrubbers which work by spraying a liquid to flow of Gas in order to absorbs the solid particles or unwanted chemical gaseous parts like NOx, Sox. In the next stage we can remove the sprayed liquid from the flow of Gas. There are some variations in design of scrubbers. For example, some scrubbers may use other chemicals such as lime or magnesium oxide to react with the SO2 in the flow of gas.


Multi Stage Gas Filter (Multi Cyclone, Filter Element)

In a Multi Stage Gas Scrubber, we define normally 2 stage. In first stage we utilize a  Multi-cyclone which based of  centrifugal force removes solid particles and liquid droplets from a flow of gas. This equipment is stationary and this is the flow of gas that rotate during passing through the Cyclone tube. Higher efficiencies and lower pressure drop make Multi Cyclones a good candidates for removal of bigger particles and droplets.

In the next stage, we remove the remaining solid particles and liquid droplets, which are smaller with dray gas filter or coalesce filter cartridges.


Filter Coalescers

We are offering Coalescing filter cartridges as a device used to produce larger droplets of liquid in flow of gas by  agglomerating smaller ones. Then at the outer layer of these filters, we have the possibility to separate these larger droplets from the flow of Gas. This filters also has a possibility to trap the solid particles.

Interval of replacement, and numbers of filters are important operating cost functions.


Process Columns

FDAN provides design and manufacture range of distillation column which is basically a tall vertical vessel in which crude oil or in general heavier products are heated and separated into its components.

A process column is a critical piece of equipment in the refining of crude oil or petrochemical plant. The applied internals like packing material is used to increase the surface area for mass transfer between gas and liquid phases during the process. The process stream is heated before entering the column, which causes partial vaporization. We are offering different process columns and related internals in a wide variety of materials, considering chemical compositions for different applications  in oil, Gas and petrochemical industries.


3 Phase Separator

FDAN designs and manufactures in advanced application of physical separation 2-3 phase separator. A vessel that separates a multi-phase flow  like the well fluids into liquid phase (oil and Water also get separated as well), gas and solids. A three-phase separator can be horizontal, vertical. This can be called  free-water because it can separate gas, oil and free water and solid particles. We offer design, engineering and manufacturing different type of 2, 3 and even 4 phase separator.


Knockout Drum

FDAN supply different knockout drums which are used to remove any oil or water from the relieved gases. Gas Flow travels upward at a designed velocity which minimizes the entrainment of any liquid droplets as it exits the top of the vessel.


Petrochemical Reactors

We offer petrochemical reactors which are enclosed volume in which a petrochemical reaction takes place. In petrochemical engineering, it is generally understood to be a process vessel used to carry out a chemical reaction, which is one of the classic unit operations in petrochemical process analysis.


Flare Stacks

In oil and gas production units or petrochemical plants we offer different type of flare stacks which are primarily used for burning off flammable gas released by safety valves during unplanned over-pressuring of plant equipment. During plant or partial plant startups and shutdowns, they are also often used for the planned combustion of gases over relatively short periods.



We are offering design, Engineering and Manufacturing different types of De-oiler in Oil, gas and petrochemical application.
