Selective removal of H2 S from an H2 S and CO2 containing gas stream

Abstract: A method and apparatus for selectively removing H 2 S from an H 2 S and CO 2 containing gas stream which has a variable flow rate. The absorption apparatus is divided into two connected individual absorption volumes in which the gas and absorbent solution can countercurrently contact each other and has means to control the passage of the fluid streams through the individual absorption volumes.

System and method for controlling secondary spray cooling in continuous casting

Abstract: A system and method is provided for cooling a continuous casting, which includes determining, for each element of steel, the steel residence time in each cooling spray zone of the secondary cooling and determining residence time flow rates as a function of average speed, grade, mold heat removal and section size of the steel strand. The system modifies the residence time flow signal using a feedback error flow signal that is derived in a feedback flow control loop. The feedback error flow signal is derived by comparing the actual measured specific flow GAL/FT 2 , based on the actual measured quantity of specific cooling water that each element of steel has received, with a calculated reference specific flow. The specific flow signal is further used to determine whether the system is to use the modified residence time flow or whether the flow should be shut off when the measured specific flow exceeds a maximum reference specific flow.

Method of making seamless tubing

Abstract: My invention relates to a process for the manufacture of seamless tubing, and particularly to a process for the manufacture of seamless tubing of molybdenum or tungsten. Molybdenum is a silver-white, very hard, brittle metal in its pure condition, with the extremely high melting point of 4748°...

Bolted and welded stainless steel connections

Abstract: Results are presented from tests and analyses of bolted connections in half-hard type 301 stainless steel, butt weldments, and transverse and longitudinal fillet welded connections in quarter and half-hard type 301 stainless steel Material thickness ranged from 0021 to 062 in (053 to 157 mm) Expressions are given for the average failure loads or stresses for the connections as a function of the appropriate material properties and geometric parameters These failure loads or stresses can be reduced by appropriate safety factors to arrive at allowable design stresses for connections in cold rolled stainless steel The welded specimen test results indicate that the use of annealed material yield strength values for the design of welded connections in cold rolled stainless steel is overly conservative
