Problems solved by technology

[0008] Separation of microbial oil from microbial residue by filtration has the disadvantage that the filter becomes clogged and requires regular cleaning
Especially when dealing with algae or microalgae, the filter can become clogged with residue that may be sticky and may contain mud (sand)

Embodiment Construction

[0020] The method of the invention separates a mixture comprising microbial oil and microbial material. The mixture may be any mixture known in the art comprising microbial oil and microbial material. Preferably the mixture comprises at least microbial oil, microbial matter and water.

[0021] Preferably, the mixture comprises, based on the total weight of the mixture, equal to or greater than 50.0 wt % to equal to or less than 99.8 wt % water; equal to or greater than 0.1 wt % to equal to or less than 49.9 wt % microbial matter; and equal to or greater than 0.1 wt % To be equal to or less than 49.9wt% microbial oil.

[0022] For example, based on the total weight of the mixture, the mixture may contain water equal to or greater than 89.0 wt % to equal to or less than 99.8 wt %; equal to or greater than 0.1 wt % to equal to or less than 1.0 wt % microbial matter; and equal to or greater than 0.1 wt% to equal to or less than 1.0wt% microbial oil.

[0023] According to the in...

Abstract

A process for separation of a mixture comprising at least a microbial oil and a microbial substance into at least a first phase comprising at least part of the microbial oil and a second phase comprising at least part of the microbial substance, wherein the separation is carried out by a cyclone type separation unit.

Description

technical field [0001] The present invention relates to a process for the separation of mixtures containing microbial oil and microbial matter. Background technique [0002] As the supply of mineral crude oil decreases, the use of renewable energy sources for the production of chemicals and fuel products is becoming increasingly important. Oil obtained from biomass, such as oil obtained from or by microorganisms, can be used as an alternative source for the production of chemicals and fuel products. One of the benefits of using oil from this type of biomass is that compared to conventional mineral crude oil, CO 2 The balance is more favorable. [0003] Oil can be obtained from microorganisms, for example, by secreting the oil from the microorganism, or by extracting the oil after breaking down the cell walls of the microorganism's cells. [0004] US2004 / 0067574 describes a method for obtaining oil from microbial cells comprising disrupting the cell walls of the microbial ...
