ABSTRACT
Synthesis of PVC as a raw material, the synthesis of hydrochloric is an essential part.
Annual production capacity of 100,000 tons of vinyl chloride plant, Bear the hydrochlo-
ric synthesis of the design section of the Process Design.
At home and abroad through the development of PVC, as well as knowledge of hydrochloric acid production in the chlor-alkali production enterprises, the use of direct synthesis of chlorine and hydrogen chloride, water absorption of hydrogen chloride from hydrochloric acid system.With the rapid development of chlor-alkali industry, synthesis of hydrochloric are also development in order to production capacity of caustic. Production in the chlor-alkali enterprises, hydrochloric are usually direct synthed by chlorine and hydrogen. And using Water absorption. When the industrial hydrochloric are product, First of all hydrogen in the reactor will be lit, and then pass into the reaction of chlorine, Hydrogen chloride gas are obtained. Hydrogen chloride gas was cooling as a hydrochloric acid absorption of water. Chlorine and hydrogen in the reaction process, the toxic chlorine gas was surrounded by an excessive amount of hydrogen so that the full reaction of chlorine to prevent contamination of the air.
In recent years, with the development of impervious graphite equipment , Preparation of the synthesis of hydrochloric have been the first iron furnace synthesis furnace to"two-in-one" graphite Furnace, "three-in-one", such as graphite furnace. Furnace through the synthesis of these different kinds of comparison, the design of the term "two-in-one" graphite furnace.
Technology and security from the comparison, the use of CAD software graphics rendering process flow chart of the hydrochloric acid. In addition, through the material balance and energy balance, as well as the main calculation and selection of equipment and equipment set out a list of the selected device.
KEY WORDS: Hydrochloric, PVC, Synthesis of Hydrochloric , synthesis furnace
