In an industrial unit for production and sales of wine the following energy sources are

consumed: LPG$,$ Diesel Oil, Crude Oil and Electricity.

For $2020$ according to the energy invoices the following energy quantities were purchased:

$($LPG$)$: $685$ tn

$($Diesel$)$: $276$ tn

Crude Oil: $523$ tn

Electricity: $640MWh$

The consumption of different energy sources is consumed in the different equipment

according to the following table

By the end of $2020$ all reserves of LPG$,$ diesel oil and crude oil are zero. The industry

operates in three shifts of $8$ hours, $30$ days per month and $7$ months per year for wine

production and in two shifts of $8$ hours, $22$ days per month and $12$ months per year for

the sales of wine.

It is noted that the sales area space heating is performed for $12$ months per year.

The characteristics of the different equipment and their operation are listed in the Table

below.

Diesel: tnx$1,097$toe$/$tn

Crude Oil $($mazout$)$: tnx$1,055$toe$/$tn LPG: tnx$1,195$ toe$/$tn

Electricity: $MWh0,086$ toe$/$MWh

$1$kcal $($thermochemical$)={10}^{{?}^{{?}^{?}}}-7$ toe.
