The present disclosure provides a system for energy recycling using mechanical vapor recompression in combined chemical process, the system including a heat exchange reactor for generating an intermediate material by means of an exothermic reaction and discharging the generated intermediate material, and heat-exchanging heat generated in the exothermic reaction with water supplied from outside so as to generate water vapor; an absorption tank for receiving the intermediate material, and mixing the intermediate material with water, so as to generate an intermediate material aqueous solution; a stripper for receiving the intermediate material aqueous solution, and separating the intermediate material into an intermediate material gas and an intermediate material water-rich aqueous solution; an endothermic reactor for receiving the intermediate material water-rich aqueous solution, and reacting the intermediate material with water, so as to generate a final product aqueous solution; an evaporation concentrator for receiving the final product aqueous solution, and heat-exchanging heat of the water vapor from the heat exchange reactor with the final product aqueous solution so as to generate steam; a dehydrating distillation tower for receiving, dehydrating, and purifying the final product aqueous solution discharged from the evaporation concentrator; and a mechanical vapor recompressor for compressing the steam from the evaporation concentrator, and providing the compressed steam as a source of heat or a source of steam supply.

The invention relates to a reaction container for stabilizing the temperature of a liquid mixture substances, the reaction container comprising an upper container part and a lower container part, in which the lower container part has an inner direct means of refrigeration and an outer indirect means of refrigeration in addition to an inner, direct means of heating and an outer, indirect means of heating.

Described herein are improved chemical reactors for carrying out partial oxidation reactions. The chemical reactor permits the use of levels of oxygen above the lower explosion limit (LEL) typically used in partial oxidation reactions, which increases both volumetric reactivity and conversion per pass, resulting in reduced separation and reactant recycle costs. Also described are methods of using the reactors.
