Abstract: An improved method for the production of stoichiometric ratioed syngas comprises partially oxidizing a gaseous feedstock containing substantial amounts of methane in a gasifier to produce a hot synthesis gas stream that is passed in indirect heat exchange through a steam reforming catalytic reactor. A portion of the steam reforming reaction products are mixed with the cooled gasifier synthesis gas stream exiting the steam reforming catalytic reactor to form a combined synthesis gas stream, called a "stoichiometric ratioed synthesis gas." The stoichiometric ratioed synthesis gas stream can then be passed into a methanol synthesis unit at substantially the specifications for optimal methanol production with little or no external compression. In a second embodiment the gasifier unit is arranged and operated in parallel with a primary steam reformer unit. The respective synthesis gas streams exiting each unit are combined to form a combined synthesis gas stream that undergoes oxidation in a secondary catalytic reformer unit to form a stoichiometric ratioed synthesis gas that requires minimal external compression before being converted to methanol.

Title: Control of the fluid loss of well drilling and servicing fluids
Inventor: DOBSON JAMES W JR
IPC: C09K8/16
Filed: 1996-06-11
Granted: 2008-10-14
Abstract: The invention provides brine based well drilling and servicing fluids containing a fluid loss control additive selected from the group consisting of (1) a crosslinked ether derivative of a partially depolymerized starch, (2) a partially depolymerized crosslinked ether derivative of starch, or (3) mixtures thereof. The fluid loss control additive provides decreased fluid losses at much lower viscosities than the corresponding starch derivatives which have not been partially depolymerized. This enables their use in fluids at concentrations sufficient to provide excellent filtration control, the fluids having a viscosity sufficient for circulation of the fluids in the borehole. The invention also provides a method of reducing the fluid loss of well drilling and servicing fluids utilizing the fluid loss control additives (1) and/or (2).

Abstract: An electronic key identifier includes first and second opposing surface segment sensors which can be clamped into engagement with the opposite sides of the blade of an unknown key blank. Each side of the key blade includes collinear surface segments separated by one or more recessed segments. Electrical conductors within the surface segment sensors contact the raised surface segments and discharge electrical energy through the grounded key blade. Appropriate electronic circuitry interfaces the conductor of the surface segment sensor with a computer to generate an electronic image of the two key blade sides. By comparing the electrical image of the unknown key blade with a database of electrical images of known key blades, the unknown key can be identified to allow the operator of a key cutting machine to quickly complete the key identification process.
