Bi- or multi-modal particle size distribution to improve drag reduction polymer dissolution

Drag reduction of hydrocarbon fluids flowing through pipelines of various lengths is improved by polyolefin drag reducer dispersions or dispersions using bi- or multi-modal particle size distributions. Drag reducers having larger particle sizes dissolve more slowly than drag reducers having smaller particle sizes. By using at least bi-modal particle size distributions drag reduction can be distributed more uniformly over the length of the pipeline where smaller sized particles dissolve sooner or earlier in the pipeline and larger sized particles dissolve later or further along the pipeline.

Bi- or Multi-Modal Particle Size Distribution To Improve Drag Reduction Polymer Dissolution

The frictional pressure drop, or drag, of hydrocarbon fluids flowing through pipelines of various lengths is preferentially lowered by dissolving therein polymeric drag reducer suspensions exhibiting bi- or multimodal particle size distributions. Drag reducers having larger particle sizes dissolve more slowly than drag reducers having smaller particle sizes, and vice versa. By using at least bi-modal particle size distributions, the drag reduction effect may be distributed more uniformly over the length of the pipeline where smaller sized particles dissolve sooner after injection (upstream in the pipeline), and larger sized particles dissolve later (further along the pipeline). Drag reducer suspensions with bi- or multimodal particle size distributions may be made by suspension polymerization.

A inhaler remote automatic adjusting device for boiler nano additive injection according to ubiquitous sensor network and method of it

PURPOSE: A device and a method for automatically controlling the injection of a boiler nano fuel additive through a ubiquitous sensor network are provided to minimize the malfunction of boiler equipment by controlling the injection and supply period of a certain concentration of nano fuel additives A and B depending on the injection of fuel oil through remote monitoring. CONSTITUTION: A sensor node unit(100) measures the nano fuel additive flux of first and second nano fuel additives and fuel additive tank levels, and a USN(Ubiquitous Sensor Network) relay node unit(200) transmits a sensing data signal to a USN main controller unit(300) of a remote place through a wired network. The USN main control unit transmits a sensor control signal for supply cycle control and the injection of the nano fuel additives A and B to the USN relay node unit.

Method and apparatus for producing synthetic fuels

In order to produce synthetic fuels, in a first phase, an educt mixture containing water vapor and an oxygenate, like methanol and/or dimethylether, is converted to olefins using a catalyst. Subsequently, the olefin mixture is then separated in a separator system into a flow that is rich in C 1 -C 4 carbon hydrates, and a flow that is rich in C 5+ carbon hydrates. The flow that is rich in C 5+ carbon hydrates is separated into a flow that is rich in C 5 and C 6 carbon hydrates, and a flow that is rich in C 7+ carbon hydrates, wherein the flow that is rich in C 5 and C 6 carbon hydrates is at least partially subjected to an etherification with methanol. The ethers thus produced are added to the gasoline product flow.

Process and plant for the production of synthetic fuels

Zur Herstellung von synthetischen Kraftstoffen wird in einer ersten Verfahrensstufe ein Wasserdampf und Oxygenate, wie Methanol und/oder Dimethylether, enthaltendes Eduktgemisch an einem Katalysator zu Olefinen umgesetzt und dieses Olefingemisch dann in einer Trenneinrichtung in einen an C-C-Kohlenwasserstoffen reichen Strom und einen an C-Kohlenwasserstoffen reichen Strom aufgeteilt. Der an C-Kohlenwasserstoffen reiche Strom wird in einen an C- und C-Kohlenwasserstoffen reichen Strom und einen an C-Kohlenwasserstoffen reichen Strom aufgeteilt, wobei der an C- und C-Kohlenwasserstoffen reiche Strom wenigstens teilweise einer Veretherung mit Methanol unterzogen wird. Die so entstandenen Ether werden dem Benzinproduktstrom beigemischt. To produce synthetic fuels, a starting material mixture containing water vapor and oxygenates, such as methanol and / or dimethyl ether, is converted to olefins on a catalyst in a first process step, and this olefin mixture is then separated in a separator into a stream rich in CC hydrocarbons and a stream rich in CC hydrocarbons. Hydrocarbon rich electricity divided. The stream rich in C hydrocarbons is divided into a stream rich in C and C hydrocarbons and a stream rich in C hydrocarbons, the stream rich in C and C hydrocarbons being at least partially subjected to etherification with methanol. The resulting ethers are added to the gasoline product stream.

The stream rich in C 5+ hydrocarbons is divided into a stream rich in C 5 and C 6 hydrocarbons and a stream rich in C 7+ hydrocarbons, wherein the stream rich in C 5 and C 6 hydrocarbons is at least partly subjected to an etherification with methanol. The ethers thus obtained are admixed to the gasoline product stream.

Method for production of fuel pellets

The present invention relates to a method for production of fuel pellets from lignocellulosic materials, namely, grass, straw, wood, sawdust, bark and agricultural residues. According to the present invention the object of this invention is achieved by a method for obtaining fuel pellets by mixing preliminary ground lignocellulosic raw material with a binding agent with the further pelletization of obtained mixture, wood bark is used as the binding agent in the amount of 10-20.% by weight of mixture, from which biologically active compounds are extracted with the use of organic solvents. The object of the present invention is achieved by that birch outer bark is used as bark, from which lupeol and betulenol are preliminary extracted, as well as bark of white alder, from which lipophilic compounds, diarylheptanoids and condensed tannins are preliminary extracted. The use of extracted bark of alder and extracted birch outer bark as the additive for pelletization of ground straw: Increases heating value of pellets Increases bulk density of pellets Decreases ash-content of pellets Increases energy density of pellets Increases parameters of attrition resistance of pellets Decreases the yield of fine unpelletized biomass Pellets on the basis of extracted bark of white alder differ from pellets on the basis of raw bark by higher heating value, higher energy density and higher attrition resistance.
