Benefits of technology

[0013]A decontamination system in accordance with the present invention is capable of accurately and continuously monitoring, identifying and quantifying contaminants. The system can sample the process stream continuously at one or more sampling points and route the samples to one or more analyzers to provide real time measurement of contaminant concentration. The system will log contaminant

Problems solved by technology

These contaminants can cause pipeline corrosion and subsequent rupture, narrowing of the line due to deposits, plugging, precipitation of solids, etc.
Hydrogen sulfide is not only harmful to humans, but when left untreated, can quickly corrode pipelines, potentially leading to ruptures and explosions.
This is an extremely low concentration and can be difficult to measure accurately.
Conventional methods for treatment of contaminants have drawbacks.
Inaccuracies in measurement of the contaminant frequently lead to overuse of injected curative.
Operators routinely overcompensate when attempting to miti

Embodiment Construction

[0024]FIGS. 1 and 2 illustrate an exemplary decontamination system 10 that is constructed in accordance with the present invention. The decontamination system 10 is operably associated with a process stream that contains at least one contaminant of interest to be neutralized. In particular embodiments, the process stream can be natural gas flowing through a pipeline. The process stream could also be a flow of other liquids, such as crude oil or water. Typical contaminants include hydrogen sulfide (H2S), mercaptans, carbon dioxide (CO2), oxygen (O2), water (H2O) and biological populations. In addition, a detected “contaminant,” as discussed herein, can include conditions that can lead to contaminants, such as conditions that are ideal for hydrate formation or corrosion.

[0025]In certain embodiments, the decontamination system 10 of the present invention can be configured as a portable, modular system that is designed to be readily moved and integrated into an existing facility having ...

Abstract

A decontamination system for decontaminating at least one contaminant in a process stream. Decontaminant liquid is dispersed into the process stream using atomization. A controller detects contaminant levels in the process stream and adjusts the flow of decontaminant fluid into the process stream in response.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The invention relates generally to systems and methods used to decontaminate process streams that contain at least one contaminant. In particular aspects, the invention relates to systems and methods for decontaminating natural gas, liquid petroleum products or water in pipelines or production streams and for monitoring and control of the decontamination process.[0003]2. Background of the Invention[0004]Regulations require companies that produce or supply natural gas, crude oil, liquid petroleum gas or water to monitor product contaminants, mitigate potential hazards and maintain quality specifications. Typical contaminants include hydrogen sulfide (H2S), carbon dioxide (CO2), oxygen (O2), and biological populations. These contaminants can cause pipeline corrosion and subsequent rupture, narrowing of the line due to deposits, plugging, precipitation of solids, etc. Hydrogen sulfide, for example, is a highly corrosive an...
