Refineries

The unprocessed crude oil has to be refined into consumable petroleum products. These refined products are usually
grouped into three categories: Light distillates (LPG, gasoline, naphtha), medium distillates (kerosene, diesel) and heavy distillates/residues (fuel oil,lubricating oils, wax, tar). From unloading the unprocessed crude to loading of the final products, Leistritz Screw Pumps are operating in various services in oil refineries.

Leistritz Crude Unloading and 7 Final Product Loading Pumps L2 and L4

Leistritz Crude Unloading and 7 Final Product Loading Pumps L2 and L4

Various types of crude oil must be unloaded from railcars or pumped from the onshore production site to the refinery. The final products are loaded onto ships, railcars or trucks. For both services Leistritz Twin Screw Pumps, series L2 and L4, are the prefered choice because of their high flow rates and self-priming, dry-running and solids handling capabilities.

Leistritz Crude Charging Pumps L2 and L4

Leistritz Crude Charging Pumps L2 and L4

Leistritz Crude Charging Pumps L2 and L4Leistritz Screw Pumps transfer and charge the crude oil to the various processes of the refinery. All Leistritz Screw Pump series can be used, however, Twin Screw Pumps of the L2- and L4-series are preferably used because of their ability to handle larger solids in the product, which offers an extended MTBF.

Leistritz Atmospheric Tank Bottoms / Vacuum Residue Pump L4The tank bottoms from the atmospheric distillation vessel must be transported to the vacuum distillation vessel. After distillation the vacuum residues are transfered to the de-asphalting process for the production of asphalt, bitumen, wax and fuel oil. These hot bottoms and residues are usually pumped with Leistritz Screw Pumps, series L4, which are designed to handle large solids at temperatures up to 320°C. The low NPSHR values of the Leistritz Twin Screw Pumps, series L4, allow a higher reactor vacuum and hence, an improved reactor efficiency.

Leistritz Slops & Drains Oil Pumps L2 and L4

Leistritz Slops & Drains Oil Pumps L2 and L4

Leistritz Slops & Drains Oil Pumps L2 and L4Various drains and waste hydrocarbons must be pumped to the separator station of a refinery. All Leistritz Screw Pump series can be used. Twin Screw Pumps of the L2- and L4-series are primarily installed because of their solids handling abilities.

Leistritz Blending / Final Product Transfer Pumps L2 and L4

Leistritz Blending / Final Product Transfer Pumps L2 and L4

Leistritz Blending / Final Product Transfer Pumps L2 and L4The clean or blended refined products are transfered to the export tanks. High viscous liquids as heavy fuel oil, paraffin, wax, asphalt, bitumen, base oil and molten sulphur as well as light products are handled by Leistritz Screw Pumps of all series. Twin Screw Pumps of the L2- and L4-series are mainly used because they tolerate large solids in the pumped product, which offers an extended MTBF.

Leistritz Circulation Pumps L2 and L4

Leistritz Circulation Pumps L2 and L4

Particularly high viscous products (e.g. asphalt/bitumen) have to be circulated in the storage tank to guarantee homogeneous product quality in all tank levels. The circulation of these hot, viscous hydrocarbons is usually done by Leistritz Twin Screw Pumps, series L2 and L4.
