Abstract: The present invention relates to a novel process for desulfurization of diesel with reduced hydrogen consumption. More particularly the subject invention pertains to an integrated process comprising diesel hydro de-sulfurisation (DHDS) or diesel hydrotreatment (DHDT) with reduced severity to desulfurize high sulfur (1.0-2.0 wt %) diesel stream to a much lower level of sulfur content of 350-500 ppm in the depleted diesel stream, followed by a novel adsorption procedure for effecting deep desulfurization to reduce overall sulfur content to less than 10 ppm with reduced hydrogen consumption, as compared to high severity DHDS or DHDT procedures of the prior art.

Abstract: The present invention provides a process for deep desulphurization of cracked gasoline with minimum octane loss of about 1-2 units. In this process full range cracked gasoline from FCC, Coker, Visbreaker etc is sent to Diolefin Saturation Reactor for selective saturation of diolefins. After saturation of diolefins, the stream is sent to Splitter for splitting into three cuts i.e Light Cut (IBP-70° C.), Intermediate Cut (70-90° C.) and Heavy Cut (90-210° C.). The Light Cut which contains majority of the high octane olefins and mercaptan sulfur is desulfurized with caustic treatment using Continuous Film Contactor (CFC). The sulfur in the Intermediate Cut is also predominantly mercaptans and the cut can be desulfurised by caustic treatment using CFC along with Light cut or separately desulfurised before being sent for isomerization. The Heavy Cut containing mainly thiophinic sulfur compounds is treated either by using conventional HDS process or reactive adsorption process.

Abstract: The present disclosure discloses a network device and/or method for centralized configuration with dynamic distributed address management. The disclosed network device receives, at a first network node, a range of sub network addresses and a specified size for a sub network. The disclosed network device then divides the range of sub network addresses into a plurality of sub-ranges of sub network addresses based on the specified size. Further, the network device allocates the plurality of sub-ranges of sub network addresses to a plurality of sub networks, and transmits an allocated sub-range of sub network addresses to a corresponding sub network at a second network node through an established secure communication channel. Moreover, the network device can retrieve a profile template that includes the range of sub network addresses and the specified size of the sub network; and create a profile based on the profile template.

Abstract: The present subject matter describes a gasification system (100) for gasifying a variety of feedstocks. A first stage gasifier (105) receives a feedstock either from a first group of feedstocks or a second group of feedstocks or both. The first stage gasifier decomposes the received feedstock to produce a first product. A second stage gasifier (115) is connected to the first stage gasifier (105) for receiving the first product. In addition, the second stage gasifier (115) receives a feedstock either from a third group of feedstocks or a fourth group of feedstocks or both. The second stage gasifier (115) gasifies the first product and the received feedstock to produce syngas.

Abstract: A process for selective removal of mercaptan from aviation turbine fuel feed includes mixing aviation turbine fuel feed with hydrogen, at a pressure in a range from 3 bar to 20 bar to obtain a reaction mixture. The reaction mixture is heated at a temperature range of 150° C. to 350° C. to obtain a heated mixture. The heated mixture is reacted with a hydrotreating catalyst in a rector to obtain a reactor effluent, and H2S gas is stripped from the reactor effluent to obtain a stripper bottom product. Moisture is removed from the stripper bottom product to obtain aviation turbine fuel product having less than 10 ppm mercaptan. The aviation fuel product has improved properties such as color and acidity. Embodiments also relate to an aviation turbine fuel product having less than 10 ppm mercaptan prepared by the described process of the present invention.

Abstract: The present subject matter relates to a process of reforming a natural gas stream by steam. The reforming is carried out at a temperature within a predetermined range to form a substantially carbon monoxide free product mixture of hydrogen and natural gas. The reforming is carried out in presence of a nickel-based catalyst. The temperature is controlled in a range of about 350° C. to about 390° C. The reforming can be started or stopped or its rate can be varied, based on an outflow demand of the product mixture of hydrogen and natural gas.

Abstract: A service discovery protocol is provided for use in personal area networks and other ad-hoc networking environments. The service discovery protocol is specifically designed to take into account the dynamic network configurations, bandwidth constraints as well as other characteristics of these types of networks. One of the key differentiators of the service discovery protocol is that it relies on a dynamically selected service directory device to manage the amount of information being distributed in the network.

Abstract: A discovery framework model includes policy information in the device/service discovery protocols. Service discovery protocols are enhanced by embedding policy information in the over all discovery framework. A method of performing policy-controlled device/service discovery includes modeling a device/service discovery protocol with a state machine either at a gateway or at discovery agents. Policies are used to control and propagate device/service discovery information. These policies are sets of rules that define conditions and attributes under which a certain action is permitted or denied.

Abstract: The present invention involves a method for multicast file distribution and synchronization in data networks. Specifically, the present invention includes a mechanism for efficient and reliable distribution of a data file from a single source to a large number of receivers using multicast distribution in wide area networks. The multicast file distribution is done by designating a receiver as an active receiver. The active receiver is selected using a novel token granting procedure. Once selected, the active receiver is responsible for generating retransmission requests as well as providing flow control feedback to the server during data transfer. All receivers on the network are offered a chance to become an active receiver in a controlled manner, and only one receiver can be an active receiver at any given time. This process continues until there are no receivers in the group with missing data segments.
