An additive for bacteria killing or decreasing their growth. For protecting oil and gas operations we need a program for controlling the microbial effects. Bacteria grows wherever water exists. In hydrocarbon production and processes use a large heavy volume of water that can create a wonderful place for bacteria growth. Their presence effects the quality and quantity of productions and the operation safety. The hydraulic fracturing and enhanced oil recovery (EOR) use more water and we should have a special biocide treatment programs for decreasing the danger of bacterial pollution creation.
Produced water and oilfield waters can have bacteria needed treatment. With biocides, an initial decrease of bacteria can happen and then help to eliminate assets corrosion, diminish souring, and increase the efficiency of biocides added in later process steps.
Initial control downhole will be provided by adding an effective biocide in injection water and hydraulic breaking liquid.
To prevent souring, assets corrosion and biofilm formation during a time, usage of biocides with effective remaining in high temperature, pressure, and brininess situations for a longer time is important.
A scatter colloid system like bole be coagulated and formed flocs by a chemical material which named flocculent. Flocculants can be in 2 forms, either multivalent cations like Ca, Mn and Al, or polymers with a long chain. Other situation, that can be a reason of bole flocculation, are high temperature, PH, and brininess.
The most popular way for de-gumming occurred by hydration, especially if the precipitate is separated and is traded as a lecithin. phosphatides, proteins, and some other colloidal impurities, which are either dissolved in the oil in very fine colloidal dispersion as long as they are anhydrous and the oil is dry, swell when wetted or hydrated and form gels of higher specific gravity, separate from the oil in flocculent particles and, if the oil is left quiescent, gradually sink to the bottom of the vessel.
In another usage, in a system with a heater which warms polluted input hydrocarbon to receive to a procedure temperature. Inducing voltage of electron applied by an ionizer to the warm hydrocarbon and in continuation, flocculent supply provides a charged flocculent into the ionized hydrocarbon. At the end of this procedure, for producing solid waste and oil, the hydrocarbon should be cleaned from all the flocculent and pollutant by a separator.
Dissolved oxygen make corrosion in oil manufacturing for removing this problem or decrease it, oil manufacturing uses Oxygen scavengers. The formulation of Oxygen scavengers is sulphite or bisulphite, and the reaction of it and oxygen has a product which is sulphate which is grouped in redox categories and its catalysts is Ni and Co. To reduce the soluble oxygen quantity before scavenger usage, the most important and necessary point is removing air in the way of defoaming and mechanical deaeration.
Oxygen Scavenger, a distributer used to prevent seawater oxygen. An inorganic chemical and active bisulfate solution composition which is a yellow buffer and water alkalinity reduction is better to store in closed device for preserving it from straight sunlight and its properties are oxidation corrosion-minimizing, oxygen omitting, PH buffering, energy saving and bio gradable.
