Title: Heavy hydrocarbon recovery from pressure swing adsorption unit tail gas
Inventor: MITARITEN MICHAEL J
IPC: C07C7/12
Filed: 2003-03-07
Abstract: A pressure swing adsorption process for the separation of impurities such as nitrogen and carbon dioxide and recovery of hydrocarbons from a natural gas stream utilizes two separate adsorption systems, the first (32) containing an adsorbent selective for nitrogen, carbon dioxide or both and the second (40) containing a hydrocarbon-selective adsorbent. In the process, the natural gas stream is passed through a first adsorbent to form a product stream (34) enriched with methane and to adsorb nitrogen and/or carbon dioxide and which further coadsorbs at least a portion of the hydrocarbons contained in the feed stream. The hydrocarbons are recovered by passing a low pressure waste stream (35) from the first pressure swing adsorption stage (32) which contains coadsorbed nitrogen and/or carbon dioxide and hydrocarbons and directing the waste stream to the second pressure swing adsorption stage (40) to adsorb the hydrocarbons and produce a product stream (42) enriched in nitrogen and/or carbon dioxide. The hydrocarbons are., recovered from the hydrocarbon-selective adsorbent by an intermediate pressure methane~containing stream (44) from the first pressure:swing adsorption stage which purges the adsorbent in the second stage which purges the.adsorbent in the second stage and forms a combined stream comprising methane and C.3 + hydrocarbons. The C3+  hydrocarbons can be separated from the methane such as by compression with flash separation or refrigeration.
Patent CA-2480405-A1 (CA)
Inventor: FANTA GEORGE F
IPC: C09K8/035
Filed: 2002-03-19
Abstract: Lubricating additives for drilling fluids are prepared from semi-solid highl y viscous and/or high molecular weight lubricants, such as polyalkylenes (e.g. , polybutene), by steam jet cooking a mixture of starch, water, and the lubricant in order to uniformly suspend micrometer-sized lubricant droplets in an aqueous starch matrix. These additives avoid the need for toxic emulsifiers, surfactants, or short-chain hydrocarbon solvents for dispersing the lubricants. They impart lubricity to drilling fluids (muds) and also inhibit fluid loss in geological formations by enhancing the filtration control properties of the fluid.

Inventor: ROZWADOWSKI KEVIN L
IPC: C12N5/06
Filed: 2003-06-05
Abstract: The invention provides methods and nucleic acid constructs that may be used to modify a nucleic acid of interest at a target locus within the genome of a host. In some aspects, the invention contemplates producing in vivo a gene targeting substrate (GTS), which may be comprised of both DNA and RNA  components. The gene targeting substrate may comprise a gene targetig nucleotide sequence (GTNS), which is homologous to the target locus, but comprises a sequence modification compared to the target locus. The gene targeting substrate may be produced by reverse transcription of a gene targeting message RNA (gtmRNA). The gene targeting message RNA may be folded for self-priming for reverse transcription by a reverse transcriptase. The gene targeting message RNA may in turn be the product of transcription of a gene targeting construct (GTC) encoding the gene targeting message RNA. The gene targeting construct may for example be a DNA sequence integrated into the genome of the host, or integrated into an extrachromosomal element. Following expression of the gene targeting systems of the invention, hosts may for example be selected having genomic modifications at a target locus that correspond to the sequence modification present on the gene targeting nucleotide sequence. In some embodiments, the structure of retrons may be adapted for use in the gene targeting systems of the invention.
