Subject field(s)
  • Risks and Threats (Security)
  • Crude Oil and Petroleum Products
CONT

Top 20 major oil spill incidents since 1967 … Oil spills in particular have been a cause of extreme concern, in spite of various safety protocols and methods to fight them established for vessels equipped to transit crude and rock oil.

English

Subject field(s)
  • Analytical Chemistry
  • Environmental Management
CONT

One untested hypothesis in oil spill response is that "chemical dispersants do not work effectively in cold water. "This is due to the general misconception that cold water inhibits dispersant effectiveness(DE) and the lack of experimental data to indicate otherwise. To address this issue, the U. S. Minerals Management Service(MMS)... conducted two series of dispersant experiments in very cold water at Ohmsett... [Both] Corexit 9500 and Corexit 9527 dispersants were more than 90% effective in dispersing the fresh and weathered crude oils tested [and dispelled] the thought that chemical dispersants cannot be effective in cold water.

CONT

Dans le cas du naufrage du TANIO, des agents dispersants mélangés à de l'eau ont été utilisés en grande quantité pour nettoyer les rochers ou appliqués purs sur les rochers mazoutés avant nettoyage. L'efficacité des agents dispersants fut le sujet d'un débat technique considérable [...]

Record 3 2005-05-05

English

Subject field(s)
  • Oil Refining
  • Water Pollution
DEF

Water which, after having been in contact with petroleum products, is recovered during the refining process. [Definition standardized by ISO.]

CONT

Process water, includes seawater(and occasionally freshwater) and produced water. Seawater is injected into a formation to pressurize the reservoir and force the oil toward the oil production wells. Gelled water is seawater and freshwater that is mixed with a gelling substance to increase the viscosity of the fluid for a number of purposes. Seawater is also used to maintain the existing wells or to detect leaks in pipelines. Produced water is the water mixture consisting of oil, gas, and sand that is pumped from oil production wells. The percentage of crude oil occurring in process water can vary somewhat based on the source of the spill.

CONT

Complete purification plant for the treatment of oily and process water.

OBS

process water: term standardized by ISO.

French

Domaine(s)
  • Raffinage du pétrole
  • Pollution de l'eau
DEF

Eau qui, dans une raffinerie de pétrole, a été recueillie au cours de la fabrication des produits après avoir été en contact avec ceux-ci. [Définition normalisée par l'ISO.]

CONT

Traitement d'eaux phénolées de procédé [...] Au premier plan, les bassins d'épuration biologique.

OBS

eau de traitement; eau de procédé : termes normalisés par l'ISO.
