Key Features of SUPERHIDIC ™
TOYO’s Service Offering
As the technology licensor, TOYO provides clients with:
- the grant of a license to use SUPERHIDIC ™ technology, and
- a Process Design Package (PDP)
Clients typically appoint their own FEED/EPC contractor, who then executes FEED/EPC based on the licensed design package.
Technology Overview
Concept of SUPERHIDIC ™
SUPERHIDIC ™ is a simplified realization of the Heat Integrated Distillation Column (HIDiC) concept, which has been recognized as the ultimate energy distillation system, implemented in a practical form suitable for industrial deployement.
Technical Features
Side heat exchangers
- Side heat exchangers can be provided at composition where enthalpy change should be provided.
- Heat transfer area can be adjusted so as to meet desirable heat duty.
- Pairing of stages between rectifying section and stripping section can be determined in consideration of desirable heat duty and temperature difference.
Columns
- Normal trays or packing is utilized.
- Side-cut to obtain intermediate product or multiple-feed can be carried out.
- Feed stage can be optimized.
Consequently, following advantages are achieved
- Highest energy saving performance in heat pump assisted distillation system developed so far.
- Good maintainability as normal facility.
SUPERHIDIC ™ is co-licensed by National Institute of Advanced Industrial
Science and Technology and Toyo Engineering Corporation.
Implementation Options (Examples)
Based on our knowledge acquired from previous design and operational experience of SUPERHIDIC ™, TOYO proceeded with further technology development.
In the previous application, the existing facilities were replaced with the new facilities. However, as a result of the technology development, existing distillation column and its auxiliary facilities can be re-used as configuration of SUPERHIDIC ™ system in maintaining excellent energy efficiency.
This re-used system contributes to further improvement of economic efficiency by reducing investment cost.
Example Configuration 1: Re-use an existing distillation column into a SUPERHIDIC ™ low pressure column
Example Configuration 2: Re-use an existing distillation column into a SUPERHIDIC ™ high pressure column
Example Configuration 3: Re-use existing distillation columns into both a SUPERHIDIC ™ low pressure column and a high pressure column
Example Configuration 4: Install a fully new SUPERHIDIC ™ system, including new distillation columns
(Notes)
- The system configurations above are examples. TOYO will propose the optimal configuration based on the client requirements and constraints.
Indirect heat pump system SUPERHIDIC ™
In systems where operating pressure/temperature of distillation column are limited, the above concept can be realized by combining SUPERHIDIC ™ technology with indirect heat pump cycles. Although indirect heat pump system are less energy‑efficient than direct ones, TOYO has developed patented technologies enabling energy savings without changing existing column operating pressure. This is especially useful for deep‑vacuum systems and heat-sensitive processes.
Features of the indirect heat pump
- Combination of multiple heat pump cycles: Efficient heat exchange can be achieved by appropriately integrating several cycles.
- Flexible working fluid selection: Working fluids can be selected to meet various constraints and enable the desired heat‑exchange performance.

Heat Integration within Existing Plants
Even when the reboilers or condensers of existing distillation columns are already heat integrated, or when surplus pressure level steam is used as the reboiler heat source, TOYO can still identify effective SUPERHIDIC ™ application opportunities by leveraging HERO, TOYO’s proprietary mathematical optimization technology.

Applications
Applications Guideline
Overhead-to-bottom temperature difference: typically less than 60 °C
- For pressurized columns, less than 80 °C may be applicable.
High-cost utilities are used, such as:
- medium or high pressure steam
- fuel gas or fuel oil
- refrigerants
Large reboiler and/or condenser duty
