Abstract: A Huber safety needle assembly including a body, configured to receive a needle. The body further including an upper portion having a first gripping portion coupled thereto, a lower portion having a second gripping portion coupled to thereto, and a hinge mechanism. The needle having a needle tip configured to be received in the body. The hinge mechanism is configured to operably transition the body between a closed configuration and an open configuration. The closed configuration allowing at least a portion of the needle, including the needle tip, to extend below the bottom surface of the lower portion of the body. The open configuration allowing the needle tip to be securely received within the lower portion such that it does not extend below the bottom surface of the lower portion.

Abstract: Embodiments provided herein relate to methods and compositions for next generation sequencing. Some embodiments include the preparation of a template library from a target nucleic acid using one-sided transposition, sequencing the template library, and capturing the contiguity information.

Abstract: In some implementations, a method for dehydrating carbon dioxide includes identifying a stream including at least carbon dioxide and water. At least a portion of the stream is dehydrated using an initial lean sorbent including glycerol and a polyhydric alcohol to generate dry carbon dioxide stream and rich sorbent including water. The polyhydric alcohol reduces an amount of glycerol lost to the dry carbon dioxide stream during dehydration. This process may result in the beneficial reduction in the amount of glycerol that leaves the system with the dry carbon dioxide. The dry carbon dioxide and the rich sorbent are separated. The glycerol is recycled by dehydrating the rich sorbent to produce recycled lean sorbent.

Abstract: A method for removing H2S from H2S-containing gaseous streams in which an H2S-containing gaseous stream is introduced into a flow channel and at least one liquid chemical H2S scavenging agent is also introduced into the flow channel. Directly within the flow channel, liquid chemical H2S scavenging agent is transformed into a plurality of H2S scavenging agent droplets, which plurality of H2S scavenging agent droplets are contacted with the H2S-containing gaseous stream, whereby at least a portion of the H2S is absorbed by the plurality of H2S scavenging agent droplets. In accordance with one embodiment, transformation of the liquid chemical H2S scavenging agent is carried out in an inclined flow channel and in accordance with another embodiment, the transformation is carried out using ultrasonic atomization.

Abstract: A process for removing H2S from a gaseous stream, wherein the gaseous stream is flowed through an absorber vessel where the stream is contacted with a sorbing liquor comprising a nonaqueous solvent containing dissolved sulfur, a tertiary amine base having sufficient strength and concentration to drive the reaction between H2S sorbed by the liquor and the dissolved sulfur to form a nonvolatile polysulfide which is soluble in the sorbing liquor, and a solubilizing agent for maintaining the solubility of polysulfide intermediates which may otherwise separate. The dissolved nonvolatile polysulfide in the sorbing liquor is converted to sulfur which remains dissolved in the liquor by contacting the liquor with oxidizing sulfur dioxide. The sorbing liquor following the oxidation of the polysulfide is cooled to a temperature at which the liquor is at or above saturation with respect to the dissolved sulfur.

Abstract: The invention relates to improvements in a known process and system wherein hydrogen sulfide is removed from a gaseous stream, using a nonaqueous scrubbing liquor in which are dissolved sulfur and a reaction-promoting amine base. In a first aspect of the invention sulfur dioxide is added to the sulfur-amine nonaqueous sorbent (or advantage is taken of SO2 which may already be present in the gas stream) to obtain better H2S removal, lower chemical degradation rates, and lower rates of formation of byproduct sulfur salts. In a further aspect of the invention the gas to be treated is mixed with oxygen and passed through an oxidation catalyst reactor to either effect oxidation of part of the H2S to form the required amount SO2 for reaction with the remaining H2S, or to effect partial oxidation of the H2S in the feed gas to form elemental sulfur, or to form various combinations of products as desired for the application, prior to scrubbing with the nonaqueous solvent.

Abstract: A method for removal of H.sub.2 S from an H.sub.2 S-containing natural gas stream in which a high surface area contactor is inserted into the natural gas stream and at least one H.sub.2 S scavenging agent is injected into the natural gas stream upstream of the contactor, the result of which is the distribution of the H.sub.2 S scavenging agent on at least a portion of at least one surface of the contactor. The distributed H.sub.2 S scavenging agent is contacted with the natural gas stream resulting in absorption of the H.sub.2 S into the H.sub.2 S scavenging agent and reaction therewith, forming at least one byproduct. Thereafter, the byproduct is removed from the natural gas stream.
