H2S Management

ICTC manufactures a comprehensive line of H2S and mercaptan liquid scavengers. The product line has evolved over time to become very effective in removing H2S from natural gas streams in a variety of applications. ICTC products are formulated to maximize absorption capacity when paired with an appropriate process to treat almost any gas stream efficiently and economically. Within ICTC’s scavenger product line – both oil soluble and water soluble formulations are available.

ICTC’s line of H2S and mercaptan scavengers are based on a proprietary blend of alkanolamine-aldehyde ondensates and specific additives to enhance preferred chemical characteristics that are required in specific applications. ICTC’s scavengers are designed to effectively perform in systems that may experience a diverse range of operating temperatures and pressures.

ICTC sweetening systems are designed to maximize the attainable reaction efficiency, which enables producers to minimize chemical consumption rates and operating costs.

ICTC’s scavenger line is comprised of various products to treat tower application as well as pipeline in line treatments, crude oil and condensate sweetening, and can be easily adapted to the typical truck scrubber pots.

Typical industrial available scavengers can promote solids. ICTC’s product line has been scientifically developed to manage these solids. Also, in the event that produced water scale is a concern, ICTC’s scavengers can include scale control additives to ensure scale is minimized.

Glycol and Amine Corrosion Control

ICTC offers water-soluble neutralizer/corrosion inhibitor for industrial glycol units.

These products are formulated to effectively inhibit the corrosive effects of dissolved gases in sour gas plant glycol units.  The result of the neutralization reaction is the formation of novel filming corrosion inhibitors that then provide a protective film on the walls of piping
and vessels.

Performance Features:

• Effective filmer
• Excellent acid neutralizing properties for effective inhibition
• Compatible with virtually all aqueous production fluids
• Does not contain any volatile alcohol based solvents

ICTC CW 888 Glycol Dehydration System Additive is a liquid blend of both organic and inorganic inhibitors, formulated especially to control corrosion in ferrous and non-ferrous metal alloy in closed triethylene glycol dehydration systems. ICTC CW 888 also contains special additives that allow increased efficiency of operation for TEG systems by effectively controlling scaling, fouling and foaming in these types of units.

ICTC CW 888 controls corrosion of piping, towers, tanks and heat exchangers by placing a protective film on metal surfaces and neutralizing harmful corrosive agents.

CTC CW 888 is uniquely designed to be effective in a wide range of conditions and is thermally stable in temperatures up to 230oC.  It is also effective in multi-metal systems and in systems with high solids content or where flow is sluggish. ICTC CW 888 contains buffering agents that will automatically work to maintain a pH in the range of 8.5 to 9.5.

For dirty systems, ICTC CW 888 has a strong dispersing action on deposits and corrosion by-products. To prevent plugging caused by rapid removal of existing deposits, badly fouled systems should be cleaned before beginning treatment.  ICTC CW 888 has the added advantage of not being preferentially removed from TEG by activated carbon filters.

ICTC CW 8090 is a unique blend of water-soluble of amines. ICTC CW 8090 was formulated specifically to deal with corrosion issues arising in industrial amine scrubber systems. ICTC CW 8090 provides efficient corrosion protection because of the filming abilities of these specialized amines. This filming ability is complimented by the neutralizing ability of these amines when they encounter acid gases within the scrubber system.

Antifoulants

ANTIFOULANTS are materials which prevent fouling  and solid deposits on heat transfer equipment. Materials that prevent deposits forming include anti-oxidants, metal coordinators and corrosion inhibitors. Compounds that prevent deposition are surfactants. They act as detergents or dispersants.

Crude petroleum, unlike many other industrial raw materials, is a natural product, and will carry with it characteristics and impurities, depending on its origin. The refinery, therefore, except for choosing among crudes available, has little control over the composition of the crude namely, sulphurous matter, acidic asphaltic/napthenic matter, salts, Fe-S compounds, etc. Added to this, problems related to presence of chemicals used in the drilling and transport operations, such as pour point depressants, demulsifiers, etc. can occur. These extraneous matters can present problems, such as fouling and corrosion, arising out of the tendencies of the impurities to interact, decompose, polymerise, etc.

The fouling problem can be severe in the reboiler/exchanger areas of crude distillation operation, especially since the operating temperatures are high in this zone and the flow/heat transfer requirements are stringent for stable operations. All the impurities mentioned above are high boilers presenting the maximum activity of polymerisation/decompostion/reaction in this zone. This leads to frequent shutdown/steaming out requirements to maintain satisfactory heat transfer rates.

A direct way to control problems associated with coke/ asphalt is to minimize its formation. Coke is produced during the steam cracking process and forms on the walls of the furnace tubes. This coke layer leads to performance problems, eventually causing the furnaces to be shut down and “regenerated.” Antifoulants passivates the areas most likely to produce coke, thereby extending the run length of the furnace.

Extending the furnace run length leads to less downtime, lower utility costs, longer furnace tube life and an overall increase in production. ICTC’s antifoulant has an additional advantage over other technologies in that it typically requires little or no capital investment on the part of
the operator.
