Abstract: A method includes optically interacting a flow of bulk material or powder in a pneumatic conveyor with an integrated computational element (“ICE”) configured to modify an electromagnetic radiation according to a characteristic of the flow of bulk material or powder. The method includes detecting the modified electromagnetic radiation with a detector, producing an output signal corresponding to the characteristic of the flow, and receiving and processing the output signal with a signal processor to yield a value for the characteristic of the flow. Also, the method includes modifying at least one of a flow rate or an air pressure in the pneumatic conveyor in response to the value of the characteristic of the flow. The bulk material or powder includes a dry cement or a dry cement component.

Abstract: Methods including optically interacting electromagnetic radiation with a flowing powder composition and a first integrated computation element (“ICE”), the first ICE being configured to detect a contaminant in the powder composition; receiving the electromagnetic radiation with a detector; and generating an output signal corresponding to a characteristic of the contaminant in the powder composition.

Abstract: A transfer system includes a conduit, a support, and a conveyor. The conduit has a first end and a second end and is configured to transfer dry material from the first end to the second end. The support is in contact with at least a portion of the conduit and is configured to maintain the second end of the conduit in a desired position relative to the first end of the conduit during transfer of the dry material from the first end to the second end. The conveyor is adjacent to the conduit and is configured to deliver the dry material to the first end of the conduit from a floating vessel configured to transport the dry material.
