Abstract: Currently, renewable plant resources are actively used as additional energy sources that meet environmental safety requirements.
However, the biodiesel production process is energy intensive, and with increased production capacity, fuel and energy costs per unit
weight of the product produced increase, which can lead to economic inefficiency and unprofitable production. Therefore, the current
task in the production of biodiesel is to reduce the material and energy costs of its production. In this regard, a system has been
developed for automatic optimization of the continuous process of transesterification of rapeseed oil with supercritical ethyl alcohol
by the value of specific raw materials and energy losses depending on the ratio of oil to alcohol consumption, which provides saving
of raw materials and energy on average by 8... 10%.
