ALOM Oxy Scav 70
passivating agent in normal applications. This chemical has a pH buffer reserve.
ALOM-Oxy Scav 70 , is a carefully selected formulation of Oxygen reactive scavenger molecules chosen to be efficient in water, and glycol dehydration systems in associate gas drying and steam and boiler feed applications
- ü Stability : The components are thermally stable up to 300 psig (21 bar).
- ü Vapour distribution: Its vapor liquid distribution ratio of one of the concentrates in the formulation is 1.26. This
means that there will be approximately 1.26 ppm of this scavenger in the vapor phase of the system for every 1
ppm of the active matter in the liquid phase. Therefore, this scavenger will partition in the system vapour and
liquids and in cool spots affording added protection to any corrosion inhibitor that is /may be used.
- ü Blowdown or venting: Natural solids may build up in the condenser knock out drums. It’s essential to blow down
the condensers. Acidic gases from the gas system or thermal degradation of glycols can cause salt formation. If the
system foams, salts travel into the condenser boxes and require cyclical blowdowns, which is a standard operating
procedure. The volatility of our scavenger or any special scavenger for glycol systems running at increased
temperatures means that the scavenger has to control oxygen in the vapour phase also. If required in higher
dosages, then there is a normal process to adequately vent to remove non-condensable gases, oxygen and
amines. These could be trapped in knockout vessels.
- ü Dissolved and dispersed Solids: Our chemical scavenger molecules and its reaction products will not contribute
to solids in the glycol system from oxygen scavenging. Note some associated gases in oil production will contain
acetic acids, hydrogen sulphide, carbon dioxide and mercaptans. Some of these have in the practice contributed to
solids from the corrosion inhibitor and neutralizing amines and inorganic buffers used in glycol systems. If
dispersed in the glycol, these are removed by glycol cartridge filter units. Entrained crude oils, asphaltenes and
formation salts, dirt are found with solids in the glycol systems are easily filtered off.
ALOM-OxyScav 70 is recommended for use as an oxygen scavenger in glycol, steam and steam reboiler systems. At low dosages it can be used to enhance de-aeration systems for water. In glycol systems, medium dosages, it can be used in maintaining cleanliness from dissolved iron reactions with oxygen.
- ü LIMITATIONS: ALOM-OxyScav 70 has some buffering functions and if there are doubts about compatibility, bottle
tests should be performed.
- ü TREATMENT REQUIREMENT: Oxygen scavenger requirements will vary according to the system variables,
obviously temperature, pressure and retention times will affect efficiencies. A ratio of 2 mg/L of ALOM-OxyScav
70 per 1 mg/L of dissolved oxygen is recommended as the treatment rate.
- ü FEEDING: ALOM-OxyScav 70 may be fed directly from the drum or diluted with glycol, water or mixtures thereof -
A blend should be checked before use.
- ü BATCH TREATMENT: A tank of water or glycol can be batch treated to tanks being filled or filled, recirculate, and
settle to react out the oxygen.
ALOM-OxyScav 70 can be injected with a normal chemical proportionating pump for continuous injection.
