APPARATUS FOR CARRYING OUT CHEMICAL REACTIONS NECESSITATING HEAT SUPPLY AT LEAST FOR THEIR INITIATION

摘要

FIELD: chemical engineering. SUBSTANCE: apparatus comprises reactor (1) of axially elongated shape, preferably of square or rectangular cross-section, having at one end at least one means for charging at least one reactant, and, at opposite end, at least one means for discharging resulting effluents. Reactor in first zone (at first end side) has plurality of heat exchange means (3) which are substantially parallel to each other and extend in form of substantially parallel layers perpendicular to reactor axis so as to form between means (3) and/or between layers of these means passages for circulation of reactant(s) and/or effluents. Heat exchange means (3) ensure heat exchange in passages due to presence of successively and transversely arranged portions which are autonomous and substantially perpendicular to reactor axis. At least some of heat exchange means (3) have pipe formed by at least one shell filled with gas or gaseous mixture for heat exchange and having at least one means for removing gas or gaseous mixture subjected to heat exchange with reactant(s) and/or effluents circulating outside of heat exchange means (3). EFFECT: effective design using new approach for organizing heat exchange.
