IPC: E21B33/068
Filed: 2004-04-16
Abstract: A method of cleaning debris from a string of production tubing in a well enables removal without pulling the string of rods that extend through the tubing. A rotary pump is suspended to a lower end of the tubing for pumping well fluid through the tubing to a wellhead at the surface. A motor assembly at the surface rotates the rods to drive the pump. A closure member is placed on a lower end of an elastomeric hose that will open when a selected level of internal fluid pressure is applied. The operator applies internal pressure to the hose at a pressure less than the selected level to increase rigidity of the hose. The operator inserts the hose through a port in a sidewall of the wellhead, the hose deflecting downward into the tubing. At a desired point, the operator increases the internal pressure in the hose to open the closure member, then discharges a cleansing fluid into the tubing, which flows back up the tubing along with debris.

Title: A reactive distillation alkylation process including in situ catalyst regeneration
Inventor: SORENSEN WAYNE L
IPC: C07C2/66
Filed: 2003-01-16
Abstract: A unified process which couples a unique in-situ catalyst regeneration proce ss with a continuous reactive distillation under pressure for the alkylation of light aromatic hydrocarbons such as benzene with C2-C30 olefins using a soli d acid alkylation catalyst supported in the reflux zone (21) of a distillation column (section A). Periodic regeneration of the catalyst (sections E, F and G) is carried out with a countercurrent injection of a C4-C16 paraffin (35) below the benzene rectification zone at the top of the column, but above the catalyst zone while the aromatic hydrocarbon reaction feedstock (17) is injected continuously at a point above a rectification zone at the base of t he column where the aromatic compound is separated from the paraffin and by- products washed from the catalyst. The use of the C4-C16 paraffin with the aromatic at a mole fraction in the range of 40 to 90% enables a regeneration temperature of about 175 - 250~C. to be achieved and maintained by adjusting the column pressure and aromatic reflux rate. Significantly lower pressures, on the order of 125 to 370 psig, are required to achieve regeneration temperature than would be otherwise required with the use only of the aromat ic hydrocarbon to dilute and wash the by-products from the catalyst surfaces.</ SDOAB>

IPC: A61F2/06
Filed: 2003-02-13
Abstract: The present invention provides an intraluminal stent comprising a metallic reinforcing component and a biodegradable polymeric material covering at least a portion of the metallic reinforcing component. The metallic reinforcing component provides structural reinforcement for the stent, but this reinforcement is insufficient, in the absence of the biodegradable polymeric material, to provide a stent capable of maintaining patency of a lumen upon implantation of the stent into the lumen. One advantage of the present invention, among others, is that a stent is provided in which reduced amounts of metallic component remain after degradation of the biodegradable polymeric material covering, in turn reducing the incidence of metal-associated adverse events that frequently follow implantation.
