Embodiments of the present invention are generally related to a system and method to remove hydrogen sulfide from sour water and sour oil. Particularly, hydrogen sulfide is removed from sour water and sour oil without the need for special chemicals, such as catalyst chemicals, scavenger chemicals, hydrocarbon sources, or a large-scale facility. The system and method in the present invention is particularly useful in exploratory oil and gas fields, where large facilities to remove hydrogen sulfide may be inaccessible. The present invention addresses the need for safe and cost-effective transport of the deadly neurotoxin. Particular embodiments involve a system and method that can be executed both on a small and large scale to sweeten sour water and sour oil.

The disclosure relates to methods, systems, and apparatus arranged and designed for converting non-methane hydrocarbon gases into multiple product gas streams including a predominately hydrogen gas stream and a predominately methane gas steam. Hydrocarbon gas streams are reformed, cracked, or converted into a synthesis gas stream and methane gas stream by receiving a volume of flare gas or other hydrocarbon liquid or gas feed, where the volume of hydrocarbon feed includes a volume of methane and volume of nonmethane hydrocarbons. The hydrogen contained in the syngas may be separated into a pure hydrogen gas stream. A corresponding gas conversion system can include a super heater to provide a hydrocarbon feed/steam mixture, a heavy hydrocarbon reactor for synthesis gas formation, and a hydrogen separator to recover the hydrogen portion of the synthesis gas.

Organic water conditioning agents may be added to an aqueous stream that is supplied to a steam generator, such as a heat recovery steam generator within a combined cycle power plant. These organic water conditioning agents may degrade to electrically-charged decomposition products that can interfere with cation conductivity measurements made on the aqueous stream. To allow deployment of the organic water conditioning agents, a sampling device can process aqueous samples to destroy interfering organic molecules, such as through heat or irradiation. Cation conductivity measurements can then be made on the aqueous sample after destroying and removing interfering organic species from the sample stream.

An evaporation system for spray evaporating undesired water comprising: a first pump, a container comprising a sump, a second pump, a spray manifold comprising a spray nozzle, a packing system disposed within the container, a third pump, and an air system comprising an air blower and an air preheater is disclosed. An outlet of a water inlet is connected to an inlet of the first pump. A first portion of a ceiling of the container is constituted by a demister element such that the first portion of the ceiling is entirely configured as an outlet for evaporated water. A second portion of the ceiling is adjacent to an upper edge of a wall of the container. An outlet of the first pump is connected to an inlet of the container. An inlet of a draw line is disposed in the sump; and an outlet of the draw line is connected to an inlet of the second pump. An outlet of the second pump is connected to an inlet of the spray manifold. The spray nozzle discharges water droplets onto the packing system. An inlet of the third pump is connected to an outlet of the sump. An outlet of the third pump is connected to a discharge outlet. The air system is disposed through the wall of the container; and the air system discharges air flow counter to and/or crossways to the water droplets from the spray nozzle. A method of using the evaporation system is also disclosed.
