20130140322 | DEVICE AND METHOD FOR DISPENSING PELLETS - A device and method for dispensing pellets from a hopper to a desired delivery point. The hopper receives and holds the pellets at an elevation above the elevation of the desired delivery point. A fixed diameter opening is defined through which the pellets pass in order to reach a conduit that directs the pellets to the desired delivery point. A localized, direct mechanical force is imparted to pellets adjacent to the fixed diameter opening to break up bridges above the opening and allow the pellets to flow through the opening. | 06-06-2013 |
20130160882 | DEVICE FOR INJECTING GAS INTO THE TUBES OF A CHEMICAL REACTOR - A device for injecting gas into a plurality of vertical tubes of a chemical reactor from the bottom. | 06-27-2013 |
20130233882 | Device and Method for Dispensing Catalyst Pellets - A device and method for dispensing catalyst pellets from a hopper to a chemical reactor. The hopper receives and holds the catalyst pellets at an elevation above the elevation of the chemical reactor. The flow of the catalyst pellets is controlled so they flow into and through a conduit in a widely spaced-apart arrangement to the chemical reactor. This controlled, spaced-apart flow is created by providing a sieve between a hopper and the conduit having openings small enough that the catalyst pellets form bridges above the openings, and then repeatedly breaking up the bridges in a controlled manner. | 09-12-2013 |
