Vacuum distillation is an important process in the pharmaceutical and chemical industry and has applications in many other sectors including beverage and food production. Another example is crude oil refining: crude oil contains heavier and lighter hydrocarbons with different boiling points, requiring two distillation processes. After atmospheric distillation, a second distillation is carried out under vacuum to separate heavy hydrocarbons at lower temperatures, minimizing thermal cracking and the creation of unwanted by-products.

Our range of vapour-compatible, corrosion-free vacuum equipment is ideal for use in distillation processes. We can offer ATEX (explosion-proof) models for use with flammable vapours, gases and liquids.

LG screw vacuum pumps are ideal for distillation applications as they generate high vacuum in a single stage. As these pumps operate without working fluids, they are able to extract media as a vapour without contamination. As a result, the media can be reused after condensation. An extensive range of sizes and models is available, including explosion-proof versions (ATEX).

Speck liquid ring vacuum pumps are extremely robust vacuum generators that are used in a number of distillation processes. They can be supplied in a wide range of series, sizes and material options to suit specific applications.

SV rotary vane vacuum pumps have been used in distillation processes for many years. These vacuum pumps have a simple but proven design. The operating fluid is supplied to the compression chambers in minimal quantities. Process-compatible fluids can be used.

Examples of vacuum technology in use in distillation processes

  • Crude Oil Distillation – Used to separate out the individual hydrocarbons
  • Solvent Recovery – Used to recover solvents from a process medium
  • Vacuum-supported Distillation – In pharmaceutical or chemical applications

Suitable products for this application

Oil Filled Rotary Vane Pumps

SV series single-stage oil-filled rotary vane vacuum pump is a reliable, durable, economical and adaptable range of vacuum pumps.

In the circular pump body, is an air suction valve and exhaust valve (stator). The vanes are equipped with an eccentric slot in the rotor. The vane blades divide the pump chamber into three parts. The volume of the pump chamber keeps changing periodically as the rotor rotates to finish the process of gas suction, compression and elimination.

Dry Screw Vacuum Pumps

LG series dry screw vacuum pumps can manage both condensable vapours and some solids with no residue. They offer a number of advantages over the traditional vacuum pump designs. There’s is no oil or water in contact with the process vapours, so therefore they are considered environmentally friendly.
