The present invention relates to drilling fluid comprising one or more linear internal olefin having from 15 to 18 carbon atoms and containing less than 25% branching based on the total amount of the linear internal olefin and a hydrogenated Fischer-Tropsch derived product.

Drilling fluid

The present invention is directed to an apparatus and method for controlling mass flow rate of a particulate solids and gas mixture to a reactor. In particular, the fast response of a mass flow rate-indicating device is combined with the longer term accuracies in changes in the total mass from weigh cells to yield rapid and more accurate loss-in-weight measurements than conventional systems.

Pressure compensated weigh system

A method and apparatus for controlling moisture content of a solid, such as pulverized coal, conveyed to a reactor, such as a gasifier, by controlling the temperature of a gas injected into a pulverizer or dryer based on the moisture content control of the coal transported to the gasifier.
