Dispersed Bubble Reactor For Enhanced Gas-Liquid-Solids Contact And Mass Transfer

Номер: US20120216680A1

Автор: Alexander Bonsu, Guohai Liu, Pannalal Vimalchand, Wanwang Peng

Принадлежит: Southern Co

An apparatus to promote gas-liquid contact and facilitate enhanced mass transfer. The dispersed bubble reactor (DBR) operates in the dispersed bubble flow regime to selectively absorb gas phase constituents into the liquid phase. The dispersion is achieved by shearing the large inlet gas bubbles into fine bubbles with circulating liquid and additional pumped liquid solvent when necessary. The DBR is capable of handling precipitates that may form during absorption or fine catalysts that may be necessary to promote liquid phase reactions. The DBR can be configured with multistage counter current flow sections by inserting concentric cylindrical sections into the riser to facilitate annular flow. While the DBR can absorb CO 2 in liquid solvents that may lead to precipitates at high loadings, it is equally capable of handling many different types of chemical processes involving solids (precipitates/catalysts) along with gas and liquid phases.

The temperature control system of the present invention is a temperature control system for recovering reaction heat inside a reactor in which an exothermic reaction takes place, thereby controlling a temperature inside the reactor. The temperature control system is provided with a coolant drum in which a liquid coolant is accommodated in a vapor-liquid equilibrium state, a heat removing unit which is disposed on the reactor to internally circulate the liquid coolant supplied from the coolant drum, a temperature determining unit which determines a temperature inside the reactor, and a pressure controller which controls pressure inside the coolant drum. The pressure controller controls the pressure inside the coolant drum based on a difference between an actual temperature inside the reactor determined by the temperature determining unit and a preset temperature value inside the reactor, thereby controlling the temperature of the liquid coolant inside the coolant drum.

MATERIAL SUBSTITUTION OF CUPROUS CHLORIDE MOLTEN SALT AND OXYGEN GAS IN THE THERMOLYSIS REACTOR OF HYDROGEN PRODUCTION Cu-Cl CYCLE

Номер: US20170015551A1

Автор: Abdulrahman Mohammed Wassef

Принадлежит:

In the thermochemical water splitting process by the Cu—Cl cycle, oxygen gas is produced by a thermolysis process in a three-phase reactor. A precise knowledge of the hydrodynamic and heat transfer analyses is required for the scale-up of the thermolysis reactor. However, in the experimental studies of the scale up analysis, there are some challenges in using the actual materials of the thermolysis reactor products (i.e. molten salt CuCl and oxygen gas). In accordance with the teachings herein, alternative materials are defined, by using dimensional analyses, to simulate the hydrodynamic and heat transfer behaviors of the actual materials. It has been found that these alternative materials are liquid water at 22±2° C. and helium gas at 90±2° C. The alternative materials provide safe environment for the experimental runs as well as lower operating temperature. Furthermore, these alternative materials are more readily available and are low cost. 1. A method of scaling-up a reactor by experimenting with at least one alternative material instead of an actual material that is used in the reactor , wherein the method comprises:selecting a study that is needed to be performed in the scale-up analysis;identifying a set of parameters that affect the study;performing dimensionless analyses on the set of parameters to select the at least one alternative material;performing experiments with the selected at least one alternative material; anddefining one or more parameters of the reactor for actual use based on results of the experiments.2.

A method for washing an oligomerization reactor using by-product solvent recovered from the reactor can include: catalytically converting a monomer in a reactor section in a reaction mode in the presence of a catalyst to form a product stream comprising an oligomer, a by-product solvent, and a polymeric by-product; separating the product stream into a first fraction comprising the oligomer and a second fraction comprising a mixture of the by-product solvent and the polymeric by-product; and separating, in a thin film evaporator, the second fraction into a third fraction comprising the by-product solvent and a fourth fraction comprising the polymeric by-product. 1. A method comprising:catalytically converting a monomer in a reactor section in a reaction mode in the presence of a catalyst to form a product stream comprising an oligomer, a by-product solvent, and a polymeric by-product;separating the product stream into a first fraction comprising the oligomer and a second fraction comprising a mixture of the by-product solvent and the polymeric by-product; andseparating, in a thin film evaporator, the second fraction into a third fraction comprising the by-product solvent and a fourth fraction comprising the polymeric by-product.2. The method of claim 1 , further comprising delivering a recycled portion of the by-product solvent to the reactor section in a wash mode; wherein the recycled portion of the by-product solvent comprises the third fraction.3. The method of claim 1 , wherein the product stream claim 1 , the second fraction claim 1 , and the fourth fraction each further comprise at least a portion of the catalyst.4. The method of claim 1 , further comprising:delivering the recycled portion of the by-product solvent to a collection vessel in the reaction mode; anddelivering the recycled portion of the by-product from the collection vessel to the reactor section in the wash mode.5. The method of claim 1 , wherein the first fraction comprises further comprises ...
