Benefits of technology

This system efficiently removes hydrogen sulfide from fluids without introducing chemical scavengers, reducing the need for secondary treatments and complex equipment, and allows for transportation and use in remote locations due to its compact design, while minimizing dithiazine buildup and maintaining the commercial value of the liquid portion.

Problems solved by technology

It is also very poisonous, corrosive, flammable, and explosive.
At higher concentrations, hydrogen sulfide is toxic and deadly.
However even though these products are non-volatile or less toxic, it is often undesirable to leave scavenger end-products within the treated fluid (since the overall “sulfur” content has not been reduced, but has merely been converted to a less toxic form).
Therefore additional steps may need to be taken to remove the scavenger end-products from the fluid, resulting in additional costs and more complex equipment.
Additionally, amine-based hydrogen sulfide scavengers are also known to form an unwanted dithiazine byproduct (particularly if the scavenger is “over-spent”).
Cleanup procedures are time consuming and difficult.
The industry places much effort and incurs great cost in the prevention and treatment of dithiazine buildup.
However, such upright / vertical orientation makes these systems undesirable for use in remote locations, because the upright vessel will often have to be transported in a horizontal orientation (e.g. to fit underneath bridges and to meet local vehicle and traffic regulations) and then be lifted or tilted upright from a transport vehicle to be installed at the remote location.
The packing, porous media or contact cells may also not be suitable for use with crude oil and / or may be expensive to use and replace.
However, this type of air stripping is normally only suitable for contaminated water with lower concentrations of hydrogen sulfide, it may not work well with crude oil and typically results in the packing becoming plugged or contaminated.
Moreover, the use of packing complicates this system and adds to the cost, including ongoing operating material costs as packing needs to be replaced.

Embodiment Construction

[0022]The following description is of preferred embodiments by way of example only and without limitation to the combination of features necessary for carrying the invention into effect. Reference is to be had to the Figures in which identical reference numbers identify similar components. The drawing figures are not necessarily to scale and certain features are shown in schematic or diagrammatic form in the interest of clarity and conciseness.

[0023]FIG. 1 shows a first preferred embodiment of a fluid treatment system 10 for treating a contaminated fluid F having a gaseous contaminant C mixed or dissolved in the liquid portion L thereof. The fluid treatment system 10 comprises a generally enclosed and substantially airtight container 12 defining an interior volume 12v. The container 12 may comprise a bottom 12b, side walls 12s, and a top 12t. The container 12 is designed to contain and hold gases and liquids. A preferred material for the container is steel. More preferably, the cont...

Abstract

In one aspect there is provided a fluid treatment system for treating a contaminated fluid having a gaseous contaminant mixed or dissolved in the liquid portion thereof. The system comprises a generally enclosed and substantially airtight container defining an interior volume. The container comprises an inlet to receive the contaminated fluid, a gas outlet to discharge any gaseous contaminant and a liquid outlet to discharge any liquid that may be separated from said contaminated fluid. During operations, the container is sealed to maintain a seal between the interior volume and any outside environment, so as to prevent the escape of any liquids and gasses out of the interior volume, except as may be provided for via the inlet, the gas outlet or the liquid outlet. Also during operations, a continuous headspace is maintained between the at least one inlet and the at least one gas outlet.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application is a continuation of co-pending U.S. application Ser. No. 15 / 154,940, which was filed on May 13, 2016, entitled “FLUID SCRUBBING APPARATUS” and which was non-provisional application of U.S. Provisional Patent Application Ser. No. 62 / 161,882 filed May 15, 2015 and entitled “FLUID SCRUBBING APPARATUS”, the entireties of each of which are incorporated herein by reference.FIELD OF THE INVENTION[0002]The field of present invention relates generally to contaminated fluid scrubbing equipment and, more particularly, to equipment and systems suitable for scrubbing hydrogen sulfide from fluids such as sour water and sour oil without introducing a chemical scavenger into the liquid portion of the contaminated fluid and without the need for a large scale facility.BACKGROUND OF THE INVENTION[0003]The background information discussed below is presented to better illustrate the novelty and usefulness of the present invention. This backgr...
