TESSO CONCEPTDEVELOPMENT FROM EMA

TESSO 觀念的發想是基於環境會計制度中物質流成本會計的理念所衍生出的結果，是物質流成本會計考量能源平衡的特例。

TESSO 觀念的發想是屬於被動式 (passive , △T<0) 的能源回收再利用，而 PINCH 是屬於主動式 (active, △T>0 ) 的能源回收再利用

TESSO 觀念的應用在於能量不滅，熱能可被全部回收再利用，因此不需由外界提供primary energy 供應。可輕易達成節能80% 的目標。

MFCA classified Output into: Products output and Non-Products output

• Increasing the productivity by:• 1. Increase the products output• 2. Decrease the Non-Products output

• MFCA focus on the Non-Products Output

Through energy conservation theory, overall of energy input would become to overall energy output. (as basic assumption that energy not go out with products, it only as the non products output, or energy become the waste after it used)

Definition of TESSO philosophy• According to energy conversation theory, in a steady state system which

energy inflow to the system should be equal to its energy outflow. (The energy neither be generated or destroyed by the system. On the other hand to said the energy only be used or degraded by the system). And the outflow energy could be reused on the system again by upgrading. This energy could be reuse again and again without any extra fresh energy input. This called “Thermal Energy self sufficient Operation (TESSO) philosophy”.

• 依據能量不滅定律，一穩態系統輸入的能量將恆等於其輸出的能量。( 系統並不會產生或消滅能量，能量僅被使用過或能階降低 ) 此一輸出的能量可經由能階提升後再度使用於此一系統上。 而此一能量可一直重複使用而無需添加額外的能量做為補充。此稱為能量自給自足的操作觀念。 ( 或稱為 TESSO 觀念 )

Energy Demand • According to Energy Conservation Theory, that energy do not consume in

a system operation. Therefore, for a process operation, we suggest to use energy demand instead energy consumption.

• On a traditional process operation that Energy Demand is equal to QH (which include the thermal energy for the operation such as thermal separation, dissolution, transformation, reaction…and the heat loses.)

• On TESSO philosophy the energy demand for the process is consider the energy requires for the thermal energy upgrading W.

• The energy requirement for the process is recirculation inside the process by installed a heat upgrading device.

Traditional energy require for the process are QH

The TESSO concept energy require for the process are W

Conclusion and Major Concepts of TESSO

• Based on the energy conservation theory. The energy cannot be generated neither destroyed by the system.

• The energy input is exactly equal to its energy output.• Energy only be used or degraded to the system which never consumed.• Energy could be upgrade and reuse again by energy upgrading devices.• The outflow energy could be upgraded and reuse again and again without

any extra fresh energy input.• The energy required to the system QH could be supply by recyclable

energy based on TESSO philosophy.• On the TESSO philosophy do not consider how much energy demand to

the system (QH)but instead by how much energy needs (W) for upgrading.• System’s operation energy could be recycle for use again and again, so

called Thermal Energy Self Sufficient Operation philosophy.
