Application of Liquid Ring Vacuum Pumps in Palm Oil Production

Liquid ring vacuum pumps (mainly the 2BE series) are core negative-pressure equipment for palm oil refining sections. Featuring water vapor resistance, isothermal compression and explosion-proof safety, they fit tropical working conditions in Southeast Asia. They are mainly used in the refining, drying, deodorization and fractionation processes of crude palm oil.

Vacuum Deodorization (Core Application)

After bleaching, crude palm oil enters the deodorization tower. High vacuum plus high temperature is required to remove free fatty acids, odorants and volatile impurities, improving the flavor and quality of oil. Working condition: Large volume of water vapor plus a small amount of organic oil vapor will be generated. Solution: Large refineries mostly adopt Roots + 2BE liquid ring vacuum units with 2BE as the backing pump. Small and medium-sized oil mills directly use single-stage 2BE liquid ring vacuum pumps. Compared with old steam jet ejectors, liquid ring units consume much less steam and are the top choice for revamping old plants in Southeast Asia.

Vacuum Drying (Dehydration after Alkali Refining)

Palm oil after alkali neutralization contains water. It is fed into the vacuum drying tank to remove water under negative pressure and prevent oil hydrolysis in subsequent bleaching and deodorization processes. Medium: Mainly water vapor with few impurities. Model selection: Single-stage 2BE liquid ring vacuum pump meets the requirement.

Palm Oil Fractionation Section

Palm oil fractionation separates oil into palm stearin and palm olein. The negative pressure environment stabilizes the crystallization temperature, enhances separation performance and ensures production of palm oil with different melting points.

Vacuum Drying of Palm Kernel Meal

Palm kernel meal obtained after palm kernel pressing has high moisture content and is prone to mildew. Liquid ring vacuum pumps create negative pressure for low-temperature dehydration to reduce moisture of meal for storage and export as animal feed.

Notes for 2BE Liquid Ring Vacuum Pumps in Southeast Asia

High ambient temperature: Malaysia and Indonesia have year-round high temperatures. Elevated cooling water temperature reduces the ultimate vacuum of the pump. Closed-loop circulating cooling systems are commonly equipped for projects. Coastal chloride ion corrosion: 304/316 stainless steel is optional for the wetted parts of pump. Capable of 24-hour continuous operation, simple maintenance and easy access to spare parts, suitable for non-stop factory production.

Key Pain Points for Application in Southeast Asia High ambient temperature: Malaysia and Indonesia have high year-round temperatures. Elevated cooling water temperature reduces the ultimate vacuum of pumps, so closed-loop cooling systems are commonly equipped in projects. Coastal chloride ion corrosion: 304 / 316 stainless steel can be selected for the wetted parts of pump. Capable of 24-hour continuous operation, simple maintenance and easy availability of spare parts, suitable for non-stop factory production.
