Process for heating coal oil slurries

PROCESS FOR HEATING COAL OIL SLURRIES ABSTRACT Controlling gas to slurry volume ratio when heating a flowing coal-oil slurry and a hydrogen containing gas stream allows operation with virtually any coal to sol-vent ratio. Controlling the gas to slurry volume ratio to achieve a gas holdup of about 0.4, and preferably 0.38, permits operation with efficient heat transfer and satis-factory pressure drops. The critical minimum gas flow rate for any given coal-oil slurry will depend on numerous factors such as coal concentration, coal particle size dis-tribution, composition of the solvent (including recycle slurries), and type of coal. Further system efficiency can be achieved by operating with multiple heating zones to provide a high heat flux when the apparent viscosity of the gas saturated slurry is highest. Operation with gas flow rates below the critical minimum results in system instability indicated by temperature excursions in the fluid and at the tube wall, by a rapid increase and then decrease in overall pressure drop with decreasing gas flow rate, and by increased temperature differences between the temperature of the bulk fluid and the tube wall. Appli-cants have further discovered that at the temperatures and pressures used in coal liquefaction preheaters the coal-oil slurry and hydrogen containing gas stream behaves essentially as a Newtonian fluid at shear rates in excess of 150 sec-1. The gas to slurry volume ratio should also be controlled to assure that the flow regime does not shift from homogeneous flow (bubble, dispersed bubble, elongated bubble, and the like) to non-homogeneous flow (stratified, slugging, plug, and the like). Although applicants have observed stable operations with a maximum gas holdup as high as 0.72, applicants prefer to operate with a gas holdup no greater than 0.68.

Method of fabricating ferroelectric integrated circuit using dry and wet etching

In a ferroelectric integrated circuit, a hydrogen barrier layer (128, 628) comprising titanium or titanium nitride or both is formed over a metal oxide element (124) to protect it from hydrogen degradation. After hydrogen annealing and other process steps causing hydrogenating or reducing conditions, the hydrogen barrier layer is removed in a two-step etching process. The first etch step is a dry etch, preferably a standard ion-mill etching process, which rapidly removes most of the hydrogen barrier layer. The second step is a wet, chemical etch, preferably using a solution containing NH 4 OH, H 2 O 2 , and H 2 O, which selectively removes remanents of the hydrogen barrier layer from the circuit by oxidizing a chemical element of the barrier layer. The metal oxide material preferably comprises a layered superlattice material.

Cathode transient humidity control in a fuel cell system

A fuel cell system that selectively causes cathode input air to by-pass a water vapor transfer (WVT) device during high to low power transients. During normal stack operation, the cathode input air is sent through the WVT device to humidify the cathode input air for proper membrane humidification. For low power stack operation, where the cathode input airflow is reduced, which reduces the ability of the airflow to drive water out of the cathode flow channels, a by-pass valve is switched so the cathode inlet air by-passes the WVT device to reduce the cathode inlet humidification. In one embodiment, heaters at the ends of the stack are turned on during the low power condition to further reduce the accumulation of water in the end channels of the stack.
