The present invention relates to a modular reactor system for carrying out processes comprising mixing, chemical reactions, heat exchange and/or separations, the reactor system comprising of at least one additive manufactured module, the module each performing at least one process unit operation, and optionally, an external housing.

A box style steam methane reformer (15) has plural sections (37), with each section having walls (27-29-31, 33) forming an interior cavity (35) and open ends (43) that communicate with the interior cavity. Each section has a feedstock supply pipe (71) and a fuel supply pipe (63) located along the top wall, as well as a syngas collection pipe (79) and a flue gas collection duct (75) located outside of the bottom wall. The pipes and ducts have ends that are aligned with each other to allow the sections to be assembled together. Burners (67) are in the interior cavity and are connected to the fuel supply pipe. Reactor tubes (59) extend through the interior cavity. Refractory members (81) are located in the interior cavity and across a slot. The spacing between the refractory members varies to control the flow of flue gas.

Disclosed are modular chemical reaction systems and methods of using such chemical reaction systems. The disclosed systems can have a substrate layer and a plurality of modules selectively mounted to an outer surface of the substrate layer. The substrate layer can include flow connectors that cooperate with the modules to form a fluid flow pathway for performing at least one step of a chemical reaction. At least one of the modules can be a process module, such as a reactor or separator. The modules can also include at least one regulator module. The system can also include at least one analysis device that analyzes at least one characteristic of the chemical reaction as the reaction occurs. The system can also include processing circuitry that monitors and/or optimizes the chemical reaction based on feedback received from the analysis device or other system components.

Systems and methods for synthesizing chemical products, including active pharmaceutical ingredients, are provided. Certain of the systems and methods described herein are capable of manufacturing multiple chemical products without the need to fluidically connect or disconnect unit operations when switching from one making chemical product to making another chemical product.

Disclosed is a jacketed, tiered baffle, bioreactor tank comprising an outer cylindrical-shaped jacket and a cylindrical tank having an inner tank surface defining a chamber configured for supporting a flexible bag disposed within the chamber, and an outer tank surface having tiered baffles configured for routing a heat exchange fluid around the entirety of the outer tank surface, the cylindrical tank disposed axially within the outer cylindrical-shaped jacket. The outer cylindrical-shaped jacket is sealed to the cylindrical tank in a manner sufficient to prevent or minimize loss of the heat exchange fluid.

A heat exchange module for use in a chemical, pharmaceutical or biological reactor system includes a generally hollow body having an interior space for receiving a replaceable or single use reactant container, and at least one thermally conductive surface adapted to contact the replaceable reactant container to facilitate heat transfer, a fluid circulation path formed within the body between an outer wall of the body and an inner wall of the body through which a heat exchange fluid can be circulated, and at least one baffle protruding from the inner wall of the body into the interior space.

Plant for the conversion of biogas into a chemical product with a high added value, selected among methanol, dimethyl ether, formaldehyde, acetic acid by a process comprising the following steps: a) reforming by converting methane and carbon dioxide contained in the biogas into syngas, b) synthesis of methanol by using syngas from step a), b) synthesis of one of the aforesaid chemical products: formaldehyde, dimethyl ether or acetic acid by using methanol from step b) c) optional purification and separation of said chemical product, characterized in that the reaction section in which the steps b) and b) are carried out or a part of it is replaceable with a further and different whole section or section part, in order to obtain one of the aforesaid chemical products different from the one obtained before said substitution.

This plant can convert almost all or all the CO.sub.2 produced in biogas plants into CO and subsequently into one or more chemical products with a high added value with revenues comparable to, if not higher than, those of traditional plants only obtainable thanks to incentives.

The plant is energy self-sustainable thanks to the use of its effluents for the production of energy and heat.

A reactor for conducting exothermic equilibrium reactions, especially for the performance of methanol synthesis by heterogeneously catalysed conversion of synthesis gas, is proposed, which enables readjustment and hence optimization of the reaction conditions along the longitudinal coordinate of the reactor. For this purpose, in accordance with the invention, the reactor is divided into a multitude of series-connected reaction cells, each of which comprises a preheating zone, a cooled reaction zone, one or more cooling zones and a deposition zone for condensable reaction products. In this way, the reaction conditions are adjustable to the respective, local composition of the reaction mixture and variable over the reactor length.

A subject of the invention is a fluidized-bed reactor for producing granular polycrystalline silicon. The fluidized-bed reactor comprises a segmented reactor tube, which is disposed between a reactor top and a reactor bottom, a heating facility, at least one nozzle for supplying fluidizing gas, at least one nozzle for supplying reaction gas, a facility for supplying silicon seed particles, a product removal line, and an offgas removal line. The segmented reactor tube comprises a base segment and at least one spacer segment, there being disposed, between base segment and spacer segment, a flat seal made from a carbon-containing material, the spacer segment consisting of a material which, within a temperature range from 100 to 950 C., has a thermal conductivity of <2 W/mK.

A modular device for treatment and/or analysis of substances comprises a supply device which supplies at least one functional fluid to at least one process device, wherein the supply device has multiple receiving means for receiving in each case one process device. The receiving means each have multiple supply ports, including an inflow supply port and an outflow supply port for transmission of a functional fluid. The process device has a functional region for the treatment and/or analysis of substances, a fluid line which encloses the functional region, and multiple coupling means for coupling to the supply ports of a receiving means. A supply device for use in a modular device and a process device for treatment and/or analysis of substances for use in a modular device are also provided.
