Distillation is the process of separating the components or substances from a liquid mixture by using selective boiling and condensation. In industrial applications, distillation is a physical separation process, not a chemical reaction. The distillation of fermented products produces distilled beverages with a high alcohol content, or separates other fermentation products of commercial value.
Feedstock
Origin and composition
The distillation method is used to separate different components from a liquid mixture via a thermophysical separation. The feedstock for the distillation process normally is coming from a process with different products and it is used to seperate those into homogenous product streams. Distillation also is an effective and traditional method of desalination.
Pre-treatment
For a distillation no specific pre-treatment is needed since it is used to separate different fraction within a process chain. Sometimes it is combined with other separation technologies.
Process and technologies
An installation used for distillation, especially of distilled beverages, is a distillery. The distillation equipment itself is a still.
Dry distillation is the heating of solid materials to produce gaseous products (which may condense into liquids or solids). Dry distillation may involve chemical changes such as destructive distillation or cracking and is not discussed under this article. Distillation may result in essentially complete separation (nearly pure components), or it may be a partial separation that increases the concentration of selected components in the mixture. In either case, the process exploits differences in the relative volatility of the mixture's components.
Products
Post-treatment
The post-treatment of the different products are depending on the next steps within the production chain.

describe the company, here is an example
ABC was founded in 20... 12 by KNN and Syncom, in collaboration with the university of Groningen, Netherlands. The company is a technology provider developing chemical recycling technologies for different feedstocks including non-food bio- and plastics waste. In 2018 a pilot plant with the capability to process biomass and plastic waste was set up at the Zernike Advanced Processing (ZAP) Facility. The company is now focused on setting up their first commercial plant with a capacity of 20,000 to 30,000 tonnes. The investing phase B was recently completed, with the last investment phase in 2019 the financial requirements are fulfilled to complete the commercialisation activities to build the plant which is expected for 2023.
describe their technology, here is an example
The technology is based on an Integrated Cascading Catalytic Pyrolysis (ICCP) process, being able to produce aromatics including benzene, toluene, and xylene (BTX) as well as light olefins from low grade biomass and plastics waste. This technology utilises catalytic cracking in a two-step process at temperatures between 450- 850 °C. In the first step the feedstock material is vaporised via thermal cracking. The pyrolysis vapours are then directly passed into a second reactor in which they are converted into aromatics by utilising a zeolite catalyst which can be continuously regenerated. Finally, the products are separated from the gas via condensation. An ex situ approach of catalytic conversion has several advantages such as the protection of the catalyst from deactivation/degradation expanding its lifetime, a greater variety of feedstock, and a precise adjustment of process conditions (e.g. temperature, catalyst design, and Weight Hourly Space Velocity (WHSV) in each step for improved yields. In current pilot plant with 10 kg h-1 feed capacity for either waste plastics or biomass, final design details are established, which will be include in the running engineering activities for the commercial plant.
