The Oil Refinery structures are our most popular product line to date. The photos above show demonstration complexes, customer orders and layouts. 

The typical oil/petroleum refinery is an industrial process plant with many different structures designed to receive crude oil , processes and refine it into petroleum products, such as gasoline, diesel fuel, asphalt base, heating oil, kerosene, and liquefied petroleum gas. Oil refineries are typically very large complexes with extensive piping running throughout, connecting the various chemical processing units. To model a complete refinery would take up a lot of space on a layout. So Model Structures has designed various stand alone structures that can be purchased separately. This way you can choose and fit the structures you like for your layout. While all standard product is designed for underground piping Model Structures will be happy to design for an additional cost the necessary above ground piping using our pipe stands to connect all purchased product. If you prefer we will also design and build complete refinery complexes based on your instructions.

The Model Structures Oil Refinery consists of the following custom built structures:
- Various sized Storage Tanks with or w/o a Pump House
- Desalting Tank
- Crude Oil Furnace
- Three different Distillation Towers
- Condensers (to be designed)
- Alkylation Unit
- Piping Complex
- Flare Tower
- High Pressure Spherical Tanks
- Vertical Storage Tanks
- Elevated Storage Tanks
- Pipe Support Columns
- Reboiler 
- Hydrocracking Unit
- Floating Top Storage Tank
- Three Unit Horizontal Storage Tank Farm with Platform

Condenser/Reflux Drum Rack (to be added soon)
- Filter Bank (to be added soon)

To aid in the selection of structures for your refinery feel free to open the link to the PDF file “How Oil Refineries are Set Up” (Updated) which gives basic in formation on how refineries operate and what structures are typically present.

                                          How Oil Refineries Are Set Up


                        Twin Vertical Storage Tanks

These tanks can be used in the refinery as storage for fuel/oil or an additive for mixing. They can also be used in an oil/ethanol refinery site as slurry or distillation tanks. The footprint is approximately 7 x 2 inches including the piping. The tanks (1 ½ inch diameter) stand about 9 inches tall.

  Elevated Storage Tank

These tanks are elevated off the ground by a set of four H-columns connected by angle iron. The smaller tank is 3 1/2" by approximately 7" with a total footprint of approx. 5" while the larger tank is 4 1/2" by approximately 8" with a total footprint of approximately 6". These tanks are designed to be used to store additives for mixing or as storage for downstream product. They can also be added on to any other products offered such as the Fuel Loading Platform (see below) or the Bulk Fuel Tower. Choose from two sizes, three colors and your favorite RR logo.

                              Pipe Support Columns

This product has been designed to compliment all the industrial trackside structures (loading platforms, tanks, tank farms) that use piping. Now pipes can be connected from tanks to platforms etc. above ground and supported using these pipe support columns. Each column measures approximately 2 1/4" high by 2" wide. Piping can be laid on any of 4 layers - ~ 1/4", 1", 1 3/4" and 2 1/4" from ground level.  The pipe support columns are sold in sets of 2 (two sets are shown below). Please visit the OnLine Store (Plastic Trackside Structures) for more information. We also have the capability to modify the pipe stands to different sizes. Just contact us for a quote.

                                           A Reboiler for your Oil Refinery

Reboilers are heat exchangers typically used to provide heat to the bottom of industrial distillation columns. They boil the liquid residuum from the bottom of a distillation column to generate vapors which are returned to the column to drive the distillation separation. The reboiler receives a liquid stream from the column bottom and may partially or completely vaporize that stream. Steam usually provides the heat required for the vaporization. Liquid residuum is pumped into the bottom of the Reboiler heated with steam with the end product a mixture of vapor and liquid sent to the next distillation tower for processing. Condensate (water from the steam process) is vented at the bottom of the tank.

Model Structures Reboiler comes standard with large input piping for steam and output piping for liquid and vapor to be sent to the next distillation tower. Input piping for liquid residuum from the previous Distillation Tower plus a smaller vent for water condensate are located on the bottom of the tank. The Reboiler comes standard with a brown tank, red oxide piping for steam, brown piping for both input and output liquids. Overall footprint for the Reboiler is about 6 inches x 6 inches. The tank is 1.5 inches in diameter and about 4 1/4 inches long.

Hydro-Cracking Unit

Fluid catalytic cracking (FCC) is the most important conversion process used in petroleum refineries. It is widely used to convert the high-boiling, high-molecular weight hydrocarbon fractions of petroleum crude oils to more valuable gasoline, olefinic gases and other products. Basically, there are two different configurations for an FCC unit: the "stacked" type where the reactor and the catalyst regenerator are contained in a single vessel with the reactor above the catalyst regenerator and the "side-by-side" type where the reactor and catalyst regenerator are in two separate vessels. The FCC designed by Model Structures for Model RR's is a 2-stage Hydro-cracker that uses two reactors. Input (feedstock) for the first reactor is high boiling point atmospheric gas oil from atmospheric crude oil distillation units or vacuum gas oil from vacuum distillation units simply referred to as gas oil. The gas oil is pumped from an upstream Distillation Tower and is mixed with hydrogen catalyst from the catalyst regenerator and pumped into the reactor where the cracking process takes place. Cracked hydrocarbons are released from the top of the tank and sent to a down-line Distillation tower where gasoline and other gas oils are created. Spent catalyst is sent back to the catalyst regenerator from the bottom of the reactor. Waste product and gas are sent from the top of the catalyst regenerator to a Flare Tower for disposal. The Model Structures design contains a 3-inch diameter reactor and a 2 ½ inch diameter catalyst regenerator. Piping for catalyst recovery is supplied at the bottom of the tanks. Output piping from the top of the reactor to a downstream distillation tower along with piping from the top of the catalyst regenerator for waste removal is included. Input piping from an upstream distillation tower and between the catalyst regenerator and reactor are also supplied. The catalyst regenerator and waste removal piping are painted red oxide. The reactor and associated piping are painted brown. The platform superstructure is painted dark gray. Overall footprint for the structure is approximately 10x 7 x15(h) inches.

                          Floating Top Storage Tank

A new addition to Model Structures Oil Refinery series this tank measures six inches in diameter and 6 inches in height. These tanks can be used to store crude or finished product. Each tank has a wrap around style stairway from the ground to a platform on top of the tank. The structure comes standard with a manway plus inlet and outlet nozzles. Decals are also available at added cost. Usual practice is not to have railing on the wind girder since it is not meant to be walked on. However railing will be supplied if desired.

                    3-Unit Tank Farm with Platform

 The latest addition to Model Structures for Model Railroads Oil Refinery Series is a large complex that incorporates three large 3-inch diameter tanks six inches long on a superstructure with lower and upper decking. Each tank has inlet and outlet piping each of which goes to ground. Pipe routing can be modified to suit customer preferences. On top of each tank there are individual man-ways and relief valves. Overall footprint is approximately 15 inches by 17 inches. As with our product Lamp posts using 12-volt bulbs and decals can be added for additional cost. Included are two fuel transfer pipe stands that swivel and rotate 360 degrees. If one of our Fuel Loading Platforms is added then pipe routing can be modified to connect the Tank farm to the Platform.

                    Tanker Car Fuel Loading Platform

The fuel loading platform has been re-designed as a pass through structure. It now measures roughly 26 x 8 x7(h). The platform is a bi-level structure with maintenance level about 2 1/2 inches high. A stairway connects the maintenance level with the top level walkway. There is a set of three pipes that runs the length of the platform. The piping can be made independent of each other, all connected or any combination desired. Normal pipe ending on the input side will be to ground unless otherwise specified. There are three gate valves one for each pipe. Each gate valve has a down spout connected to it.
Standard colors are a black superstructure with aluminum platforms / railings / stairways, piping and valves.
This platform would work well either connected to a pipe distribution network as shown or to any of the various storage tanks we offer.
