A centrifuge () for separating intermixed particulate material of different specific gravity. The centrifuge () comprising a centrifuge bowl () having a plurality of annular recesses (), a housing (), an inlet (), and means for rotating the centrifuge bowl () about the central axis (). An annular cavity () is defined between the housing () and the centrifuge bowl (). The annular cavity () is fluidly connected to the plurality of annular recesses () on the inner surface of the centrifuge bowl by a number of perforations in the centrifuge bowl wall (). The annular cavity () has a fluid inlet to provide fluid into the annular cavity. The annular cavity () has an accumulated cross-sectional flow area (A) at two different heights in the annular cavity that differs by at least a factor

Centrifugal separator having an improved flow and system comprising such a centrifugal separator

A compacted block of material constructed of one or more units consisting of matter comprising an ammonia-saturated material capable of reversibly desorbing and ad- or absorbing ammonia surrounded by a gas-permeable enclosure made of a flexible material having a thermal conductivity of at least about five times the thermal conductivity of said ammonia-saturated material at &#x2212;70&#xb0; C. to 250&#xb0; C. and methods for producing the same are described.

Connected heat conducting structures in solid ammonia storage systems

A compacted block of material constructed of one or more units consisting of matter comprising an ammonia-saturated material capable of reversibly desorbing and ad- or absorbing ammonia surrounded by a gas-permeable, flexible material having a thermal conductivity of at least five times the thermal conductivity of said ammonia-saturated material at &#x2212;70&#xb0; C. to 250&#xb0; C. and methods for producing the same are described.

Disclosed is a self-supporting solid compacted composition of material comprising an ammonia storage material capable of reversibly absorbing and desorbing ammonia in its ammonia saturated state and compacted to such a density that it has of at least 70% of the single crystal density of said material in its ammonia-saturated state in admixture with one or more additive incapable of storing ammonia and having a thermal conductivity of at least five times the thermal conductivity of the ammonia storage material at a temperature of from at least &#x2212;45&#xb0; C. to 250&#xb0; C., as well as a process for preparing it.

Additives for highly compacted ammonia storage materials

A method is provided for estimating the degree of saturation (S) of a reversible solid ammonia storage material () in a storage unit (). The storage unit () is equipped with a heater () to release ammonia and a connected tube () for ammonia flow. The initial temperature (T) is measured with a sensor () in or around the storage unit () before any heating is initiated. Heating is initiated while recording the active time of heating (t) or the amount of energy (Q) released by the heater. The desorption pressure created by solid storage material in the storage unit () is measured via a pressure sensor () in fluid communication with the storage unit (). The time (t), or the heat (Q) where the pressure reaches a certain target pressure (P) is recorded. The values of the target-pressure time (t), or the target-pressure heat (Q), and the initial temperature (T) are used to compute an approximate degree of saturation (S).

Method for determining the degree of saturation of solid ammonia storage materials in containers

A method of saturating reversible ammonia storage materials inside a container for the purpose of achieving high volumetric ammonia storage capacity and containers filled with the materials are disclosed.

Saturation of ammonia storage materials in containers

A system for storage and dosing of ammonia, including a solid ammonia storage material capable of binding and releasing ammonia reversibly by adsorption/absorption. The system is able to release ammonia gradually according to a demand that can vary over time with intermediate periods of no ammonia demand. A main storage unit and a start-up storage unit are provided. The storage units hold ammonia storage material. At least one one-way valve is provided via which the one main storage unit is in communication with the start-up storage unit. The one-way valve prevents any back-flow of ammonia from the start-up storage unit to the main storage unit. Heating devices are arranged to heat the main storage unit and the start-up storage unit separately to generate gaseous ammonia by thermal desorption from the solid storage material. A controller controls the heating power of the main storage unit and the start-up storage unit, thereby enabling ammonia release from at least one of the start-up and/or the main storage unit. A dosing valve controls ammonia flow from the storage units according to a demand.

Release of stored ammonia at start-up

A method for saturating or re-saturating ammonia storage material () capable of reversibly absorbing and desorbing ammonia in one or more storage containers (), wherein said material is partly or fully depleted of ammonia, with ammonia to a predetermined saturation degree comprises a. placing the storage container(s) () in direct or indirect contact with a thermostatting medium () at a temperature level T&#x2266; about 65&#xb0; C.; and b. connecting the storage container(s) () to a source of gaseous ammonia wherein at least during a part of the method the gaseous ammonia during saturating or re-saturation of the ammonia storage material () is at a pressure P&#x2266; about P, wherein Pis the ammonia pressure during saturating or re-saturating of the ammonia storage material () and Pis the equilibrium vapor pressure of liquid ammonia at the temperature level T.

Method for saturating and re-saturating ammonia storage material in containers

A process for saturating a material capable of binding ammonia by ad- or absorption and initially free of ammonia or partially saturated with ammonia comprises treating said material under a pressure and associated temperature located on the vapor pressure curve of ammonia with an amount of liquid ammonia sufficient to saturate said material and an additional amount of a cooling agent selected from liquid ammonia, liquid or solid CO, hydrocarbons and hydrohalocarbons that have a higher vapor pressure than ammonia, ethyl ether, methyl formate, methyl amine and ethyl amine, such that |Q|&#x2266;|Q|+Q, wherein Qis the amount of heat released from said material when it absorbs ammonia from the liquid phase thereof to the point where it is saturated with ammonia, Qis the amount of heat absorbed by said cooling agent when it evaporates, and Qis the amount of heat exchanged with the surroundings and is positive, if heat is removed from the process by external cooling, and negative, if heat is added to the process from the surroundings.
