Petrochemical

From pulling the crude oil out of the ground, to refining and specialty product production, the petrochemical industry is a very large and diversified user of vacuum systems. Steam ejectors, vacuum pumps and hybrids are commonly used in refineries. Typical applications include:

Deaeration of Injection Water – Removal of oxygen from well injection water to help prevent corrosion and solids build-up in sub-surface formations.
[Hybrids]

Degasification (Stabilizing) Crude Stock– Removing hydrocarbon gas and hydrogen sulfide from crude prior to bulk (atmospheric pressure) storage.
[Ejectors, Pumps, Hybrids]

Wash Water Deoxygenation – Removal of air and gasses from wash water used to remove dissolved salts from crude stock.
[Ejectors, Pumps]

Vacuum Distillation – The most common application for vacuum in a refinery; it prepares oil stock for “cracking” and the production of gasoline. Other vacuum distillation applications include lubricating oil production, bitumen and dewaxing.
[Ejectors, Hybrids]

Hydrotreatment – The removal of contaminants from feed stocks and vacuum removal of water (drying) when steam stripping is used.
[Ejectors, Hybrids]

Vacuum Stripping – Vacuum is used to strip and remove various components from product stocks, including gas oil drying, solvent removal from lubricating oils, furfural extraction and solvent dewaxing.
[Ejectors]

These are only a few of the most common applications. Please contact Unique for additional information and applications assistance for your specific requirements.
