    Practical Action Consulting (PAC) is the consulting arm of Practical Action, an international non-governmental organisation that uses technology to challenge poverty in developing countries. Through technology PAC enables poor communities to build on their skills and knowledge to produce sustainable and practical solutions - transforming their lives forever and protecting the world around them. Every year PAC uses technology to help over 1 million people out of poverty.

    The Global Environment Centre Foundation (GEC) is an entity that supports the UNEP’s International Environmental Technology Centre (IETC), based in Japan. GEC is dedicated to the transfer of environmentally sound technologies, in both developing countries and countries with economies in transition. The foundation aims to contribute to Japan’s international efforts on the environment, sharing project collaborations as well as promoting Japan’s rich conservation knowledge and experience in developing nations.

    Objective:

    Conventional distillation columns operate by heating with the reboiler at the bottom, and cooling by condenser at the top. SUPERHIDIC technology operates two columns: stripping section (low pressure column) and rectifying section (high pressure column), which realizes interated heat transfer from HP column to LP column).

    Key features are as follows:

    Side-exchanges accomplished by stabbed-in heat exchangers

    Distillative separation particularly of thermolabile volatile substances is often associated with a significant reduction in quality due to the thermal degradation of the substances being distilled. For example many substances containing plant matter such as essential oils can scarcely be distilled without degradation. State-of-the-art distillation methods are based mainly on steam distillation as a carrier steam distillation for primary extraction which merely results in a complex mixture of substances as essential oil.

    Isopropanol (IPA) is an important solvent and cleaning agent with wide applications in semiconductor microelectronic and pharmaceutical industries. IPA is primarily produced by combining water and propene in a hydration reaction. The IPA produced is usually in a mixture with water and distillation is used to obtain IPA with 87.9% purity. Higher purity IPA can only be achieved through azeotropic distillation with cyclohexane or diisopropyl ether. In both cases large amount of energy is used for the purification process.
