A device for injecting gas into a plurality of vertical tubes of a chemical reactor from the bottom. The present invention relates to a device for injecting gas into tubes in a chemical reactor, and more specifically for injecting gas into the bottom of the tubes. The gas may be injected for the purpose of pressure testing the tubes, for blowing out the tubes in order to clean them, or for other purposes.

Device for injecting gas into the tubes of a chemical reactor

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.

Device and method for dispensing catalyst 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.

Device and method for dispensing pellets

A device and method for automatic unloading of particles from the vertical tubes of a chemical reactor automatically feeds a fish tape into the bottom of the vertical tube to contact and dislodge the particles and automatically retracts the fish tape to allow the particles to fall out of the tube.

Device for unloading catalyst from a reactor vessel

A method for grit blasting tubes and for blowing swabs through tubes, automatically sensing that the swab has passed through the tube, and logging the event. Also, various methods are used for inserting the swabs into the tubes efficiently.

Method of cleaning tubes

A method for converting a watertight carrying case into a desk that includes mounting a bracket onto rearward projections from the case for permitting the case to serve as a desk without compromising its watertightness.

Carrying case conversion to desk

A method for marking a specific tube in a shell and tube heat exchanger includes inserting a marker into a second tube adjacent to the tube to be marked and directing a directional pointer on the marker toward the tube to be marked.

Method for marking tubes in a shell and tube heat exchanger

A device and method for loading catalyst pellets into reactor tubes of a chemical reactor. A direct mechanical force is applied to one or more pellets where bridging occurs that is different from the forces applied to the surrounding pellets in order to break up the bridge so as to allow catalyst particles to fall through an opening into the reactor tube.

Device for loading catalyst into a reactor vessel

A device and method for vacuuming solid particles out of a chemical reactor tube. One embodiment comprises the step of substantially reducing the vacuum level applied to the vacuum conduit when the conduit reaches a desired depth within the reactor tube by using means responsive to the depth to which the vacuum conduit is inserted into the reactor tube.

Vacuum attachment and method

A seal for sealing against the interior of a tube includes upper and lower rigid plates with flexible plates between them, which are compressed to form a seal.

Seal for tube

A device and method for loading pellets into chemical reactor tubes.

Device for loading chemical reactor tubes

A device and method for identifying the tubes in a tubesheet, including locating a support element along a portion of the tubesheet with at least one means for identifying the location or condition of the adjacent tubes.
