Oil & Gas Industry
Oil and gas production typically involves the use and production of large volumes of water in a variety of applications. The industry recognises its dependence on water and is focused on minimising its use, increasing reuse and recycling opportunities, and improving treatment technologies and disposal options.
TETERADOM offers sustainable total solutions for water treatment in the oil and gas industry, taking into account a wide range of technologies and strategies.
APPLICATIONS
– Water Injection for Enhanced Oil Recovery (EOR)
– Recycling and reuse
CASE 1.
Oil Production Plant
(Heilongjiang，China)
We have identified the following areas of concern:
1. The pipe wall of the cooling circulation system of the dilute oil station is scaled and clogged to a significant extent. The system had to be shut down for cleaning after three months, which resulted in an increase in workload and a disruption to the normal operation of production. The high water injection pressure and diverse water quality in the reinjection water system result in differences in water quality and changes in pH value after injection into oil wells, which often lead to scaling and corrosion in the system and, subsequently, affect production.
2. Following the addition of surfactant and alkali to the re-injection water, sediment is immediately produced, resulting in a blocked mixer and, consequently, an inability to produce. The mixer must be cleaned at least once a week.
Installation:
Effect of Use：
Following almost a year of operation, the cooling and water injection circulation systems at the dilute oil station have demonstrated positive outcomes. The circulating water system has proven effective in high-hardness water conditions.
A comparison of the scaling conditions before and after the installation of the quantum ring in the cooler of the dilute oil station, along with the operation of the water-injection motor, demonstrates the remarkable descaling and anti-scaling capabilities of the quantum ring. Its performance is exceptional, offering significant benefits in terms of energy consumption, drainage, environmental protection, manual cleaning workload reduction, and equipment service life extension.
Before
After
Summarize
The TETRADOM quantum ring increases the concentration ratio of circulating water, allowing the equipment to operate normally in high-hardness environments. By reducing scale build-up, the ring improves heat exchange efficiency and saves energy. It also helps to reduce emissions, conserve water resources and protect the environment.
CASE 2.
Oil Production Plant
(Liaoning,China)
The main issues that need to be addressed are as follows:
1.The oil production plant is situated in the world’s largest reed field and Asia’s largest wetland, where the water contains a significant microbial population. The formation of a considerable amount of slime within the circulation system has an adverse effect on the cooling efficiency of the cooling tower. The slime deposits reduce the heat transfer efficiency of the heat exchanger. The slime that accumulates on metal surfaces can cause severe corrosion under insulation, which in turn prevents corrosion and scale inhibitors from exerting their full effect on metals.
2.The factory equipment has been in operation for a considerable period of time, resulting in severe corrosion and scaling of the equipment and pipelines. In particular, the oil field water injection system is obstructed and requires a shutdown to clear it.
Installation:
Effect of Use：
Jun. 22-Sept. 6, 2018
The trial period will commence on 22 June and conclude on 6 September 2018.
1.The total number of bacteria was reduced by 72.84%.
(1)The oil content of the sewage was reduced by 24% as a result of the treatment process.
(2)The suspended solids content decreased by 76.45%.
(3)The median particle size of suspended solids was reduced by 41.54%.
(4)The number of sulfate-reducing bacteria was reduced by 82.14%.
(5)The number of iron-reducing bacteria was reduced by 93.6%.
2、During the initial stage of installation, the water quality will become turbid and a considerable amount of scale will be washed out. It is important to clean the system in a timely manner to avoid any blockages. Following an initial adjustment period, the water quality will gradually improve. While the hardness levels will increase, the system will continue to function normally.
Summarize
1、In an environment with a high microbial count, TETERADOM quantum ring can prevent bacterial reproduction in the water, avoid the formation of microbial slime and reduce the damage caused by microbial slime to the water circulation system.
2、The TETERADOM quantum ring is effective in removing both deposited scale and rust, and in preventing scaling in the event of high water hardness. The use of supplementary water can be significantly reduced. Furthermore, there is no requirement for maintenance, which helps to reduce labour costs and improve overall efficiency.
