Restoring Cooling Tower Outlet Fog into Water Cycle Type II

The invented system used in wet cooling tower, restore outlet fog of cooling tower into collection basin and consequently cooling water cycle. This invention consists of three main components; pump and its pertaining piping, waterfall and micron fog eliminator. In the first stage, the air containing fog is passed through a waterfall before exhausting. This action causes some portions of fog to condensate and fall down, remaining droplets of the fog grow and together with air cross the fog eliminator blades. Fog's droplets are entrapped between blades, leave the air, and restore to the tower. Therefore, humidity of exhausted air from tower will be effectively reduced.

INHERENTLY SAFE OXYGEN/HYDROCARBON GAS MIXER

Provided herein is a gas mixer for the safe mixing of a hydrocarbon containing gas with a gaseous oxidant. The gas mixer and method for mixing described includes a closed mixing vessel where bubbles of gas injected at the bottom of the vessel are mixed during their rise to the top of the vessel, forming a homogeneous mixture that can safely be removed. This simple design and method allows for safe mixing of gases and is applicable to catalytic oxidative processes such as oxidative dehydrogenation of paraffins where there is a risk of thermal runaway of reactions.

GAS HEATER

A heating system and a process for heating a pressurized feed gas is provided, where the heat for the reaction is provided by resistance heating by means of electrical power.

STRUCTURED PACKING FOR GAS PHASE REACTOR

The present technique presents a structured packing module 100 for a gas phase reactor 2, the structured packing module 100 comprising a structured packing 1 having a central axis 5x extending along a longitudinal direction, and may further comprise an inner tube 5 extending coaxially with the structured packing and along the longitudinal direction. The structured packing 1 includes a plurality of corrugated sheets 10, 20, 30, each arranged circumferentially around the central axis 5x and having a first end 101 and a second end 102 spaced apart from each other along the longitudinal direction. Each corrugated sheet 10, 20, 30 includes corrugations 9 extending between the first end 101 and the second end 102 and disposed at an acute angle A greater than or equal to 5 degree and less than or equal to 30 degree with respect to a line 5y parallel to the central axis 5x. The corrugated sheets 10, 20, 30 are arranged to radially overlap with each other such that the corrugations 9 of adjacently disposed corrugated sheets 10, 20, 30 are arranged in a crisscross relationship. The structured packing module 100 includes a gas flow path 40 comprising at least one inter-sheet gas flow path 42 defined between the adjacently disposed corrugated sheets 10, 20, 30.

Countercurrent contacting devices and method of manufacture
11701627 · 2023-07-18 · ·

The contacting device for countercurrent contacting of fluid streams and having a first pair of intersecting grids of spaced-apart and parallel deflector blades and a second pair of intersecting grids of spaced-apart and parallel deflector blades. The deflector blades in each one of the grids are interleaved with the deflector blades in the paired intersecting grid and may have uncut side portions that join them together along a transverse strip where the deflector blades cross each other or adjacent opposed ends of the deflector blades and cut side portions that extend from the uncut side portions to the ends of the deflector blades. At least some of the deflector blades have directional tabs and associated openings to allow portions of the fluid streams to pass through the deflector blades to facilitate mixing of the fluid streams.
