Refinery Vacuum System

Refinery Vacuum System

Croll Reynolds vacuum systems are a low cost and efficient solution for the vacuum distillation application. Vacuum distillation is a common method to separate mixture components under reduced pressure. Vacuum distillation is mostly utilized to allow lower boiling point compounds to separate from higher boiling point compounds in the mixture introduced in a vacuum tower. Refineries are one of the main areas where Croll Reynolds vacuum system helps the process of distillation to extract and capture light hydrocarbons that disassociate from crude oil, which helps avoiding problems such as thermal degrading or discoloration of the products.

Around 70% of the refineries across the world utilize vacuum distillation unit (VDU), after using atmospheric distillation unit (ADU) from where the bottoms are sent to VDU unit and increase the production of high-value petroleum products. Croll Reynolds Ejector vacuum systems offer a reliable and economical means of handling and compressing large flows of light hydrocarbons our of Vacuum distillation tower from designed vacuum level to desired back pressure in the main condensate drum, where sour condensate water separates from slop oils.

Advantages

These are the primary advantages of installing ejectors versus mechanical pumps for high-volume, low-pressure applications.

• Lower operating costs
• Prevents hydrocarbon chains from breaking from undue, excessive heat
• Reduces other undesirable secondary reactions
• Increases product recovery
• (under maximum temperature constraints)
• Reliable, consistent service and output
• No moving parts
• Low initial cost (compared to mechanical pumps)
• Minimal maintenance cost (compared to mechanical pump)
• Easy to operate and maintain
• Easy to retrofit or upgrade
• Long lasting and durable equipment
• Can be constructed from a wide variety of steel, alloy, high alloy, including corrosion resistant coatings of all components.
