原油脫硫一直是油田化學領域的難題，雖然原油中硫含量并不是特別高，但是其對于開采、儲運及后期煉化設備會造成嚴重的腐蝕，無形中增加了運營成本，加重開發商負擔，還會對環境造成污染。此外，硫化氫氣體更是一種能夠致命的有毒氣體，所有的油田現場工作都對硫化氫泄漏嚴防死守。
近年來，業內對于原油中硫的防治研究一致沒有中斷，但大多數都停留在降低采出原油的降硫技術層面，對現場工作的安全沒有實質性的提高。近日，OriginClear公司宣布該公司的降硫劑H2S－N可以注入地層，從根本上解決原油含硫的問題，大大提高了原油脫硫效率，提高了現場工作的安全性，降低了后期處理成本。
強強聯合 攻克難題石油圈原創www.h29736.cn
OriginClear是一家領先的水處理公司，該公司宣布Cobalt Aqua Control LLC（簡稱Cobalt公司）已經將15桶注入式原油脫硫劑銷往南德克薩斯州的一家原油開發商手中進行應用，原油脫硫劑采用的是OriginClear公司的專有技術。
Cobalt是一家致力于石油與天然氣技術發展的公司，總部位于美國休斯敦,OriginClear與 Cobalt強強聯合，推出新型原油脫硫劑。在低油價的形勢下，新型原油脫硫劑為高含硫原油的開發注入一劑“強心劑”。
在經OriginClear授權后，Cobalt采用其專利產權技術，研發成功新型原油脫硫劑H2S-N。該技術可以顯著提高原油采收率，大幅度降低原油中硫化氫含量，降低原油運輸與儲藏的風險，提高原油市場價值和安全性，保護環境。
將H2S中和劑作為注入劑注入生產井中，已經被證明可以顯著提高原油采收率。使用該注入劑后，井口生產穩定壓力的增加是對該注入劑性能最好的證明，此外H2S中和劑可以明顯減少原油中硫化氫的含量。
Cobalt公司創始人兼經理William Germano Jr講道：“在第一次硫化氫中和劑的現場試驗中，中和劑成功將天然氣井口壓力由不穩定的20psi提升至40psi，持續時間為6個月。同OriginClear的合作，有助于油氣運營商提升產量和降低環境影響”。
除對井口壓力進行測試外，還針對原油中含有硫化氫的問題還進行了試驗。硫化氫是一種腐蝕性氣體，會使原油酸性增加，降低原油市場價值。在試驗中，硫化氫測定含量從200ppm降至儀器無法讀取值。
OriginClear 公司科技總裁Kindler說道：“目前，開發商由于原油的高酸性每年要損失高到130億美金，當今原油價格依舊低迷，開發商為解決上述問題絞盡腦汁。Cobalt公司創新性開發原油脫硫劑，并獲得非常好的效果，我們很高興與Cobalt公司成為合作伙伴?！?/span>
減少原油中的硫化氫含量，不僅可以將原油價值提升8%到10%，而且還可以提高工作人員的安全性、減少后期維護工作，因為即使原油中僅含5ppm的硫化氫，儲存、運輸原油的油罐、管道都需要進行經常維護。
在2015年10月，OriginClear第一次宣布該公司具有專利產權的電氧化技術，在不使用化學藥劑的情況下，通過廢水處理，可以消滅96%以上的細菌和97%以上的硫化氫。測試結果來源于試驗室與美國鷹灘頁巖礦區現場分別的測試。在最近Cobalt測試中，該測試結果同樣被驗證。
高含硫原油中硫的含量高達0.5%，部分以硫化氫的形式存在。在墨西哥灣、南美和加拿大地區，這種問題更加普遍。歐佩克國家生產的原油也存在上述問題。

OriginClear Inc, a leading provider of water treatment solutions, today announced that Cobalt Aqua Control LLC (Cobalt) recently shipped its first commercial sale of 15 barrels of an injectable crude oil sweetening liquid, produced with OriginClear technology, to an oil operator in South Texas.
Cobalt is a developer of oil and gas technology and remediation solutions based in Houston, TX. OriginClear licensed its Advanced Oxidation (EWS:AOx?) technology to Cobalt, and, through a wholly-owned subsidiary, has a significant membership interest in Cobalt. Cobalt’s process produces a liquid that can significantly improve oil recovery, reduce corrosive gas in the crude stream, and increase overall ROI for operators.
Known as H2S-Neutralizer? (H2S-N?), this injectable liquid has demonstrated a dramatic improvement in oil recovery ratios, as evidenced by a stable increase in well-head pressure. In addition, H2S-N has been shown to significantly reduce hydrogen sulfide (H2S) concentration in the crude stream.
“In the first field trial we did with H2S-N, we were able to increase wellhead pressure in a gas well from an unstable 20 psi to an average 40 psi for a six-month period,” said William Germano Jr., Co-founder and Manager of Cobalt Aqua Control. “Working with OriginClear will help oil and gas operators get more value out of their production, with minimal environmental impact.”
In addition to wellhead pressure testing, other tests were performed with crude oil contaminated with H2S, or hydrogen sulfide, a highly corrosive gas that helps cause crude oil to become “sour” and lose value in the market. In field tests, hydrogen sulfide was measured from a 200 ppm concentration down to Below Readable Value (see pp. 5 and 6 of the lab report).
“The market imposes a penalty for sour crude of about 13 billion US dollars annually,” said Jean-Louis “JL” Kindler, President of OriginClear Technologies. “With oil prices still very low, producers are eager for any solution to the problem. Cobalt has an innovative approach of selling liquid, which generates a recurring revenue stream. We are delighted to be partners in this venture!”
Reducing hydrogen sulfide in crude oil can not only improve the value of crude by 8 to 10%, but also worker safety and logistics, because containers and pipelines require frequent maintenance when used with crude oil contaminated with as little as 5ppm of H2S.
OriginClear first announced in November of 2015 that its proprietary electro-oxidation technology can effectively remove 96 percent of bacteria and 97 percent of hydrogen sulfide (H2S) from produced water, without chemicals. Results were reported after lab and field testing on produced water from the Eagle Ford shale, and further validated in the recent Cobalt tests.
According to petroleum.co.uk, “Hydrogen sulfide is famous for its ‘rotten egg’ smell… Hydrogen sulfide is so much of a risk that sour crude has to be stabilized via removal of hydrogen sulfide before it can be transported by oil tankers…
“Sour crude oil will have greater than 0.5% sulfur and some of this will be in the form of hydrogen sulfide… It is more common in the Gulf of Mexico, Mexico, South America, and Canada. Crude produced by OPEC Member Nations also tends to be relatively sour.”
