Spanchem Technologies efficiently removes fouling deposits from heat transfer equipment, boilers, and other industrial equipment by circulating chemical solvents under controlled temperature, pressure and time conditions.
Spanchem Technologies leads the industry in pre-operational and operational chemical cleaning with over 15 years of experience. This plays a vital role in assuring that the plant and product specifications will be met at the very outset of facility start-up and throughout the operational cycle. The facility will operate smoothly, efficiently, and on schedule. Troublesome and costly start-up difficulties due to undesirable deposits are eliminated.
We custom engineer each individual chemical cleaning job to provide a complete, high quality cleaning service. We analyze your equipment, processes, and deposits to design a cleaning process to fit your individual plant needs and select the optimal cleaning solvent system.
A series of chemical cleaning centrifugal pumps, specialized chemical hoses, heating units, filters and chemical mixing tanks are typically used to establish optimal circulation loops.
Each chemical cleaning project is custom engineered to deliver optimal treatment, taking into account:
- Deposit Sample Analyses
- Solvent/Metallurgy Compatibility
- Process Loop Geometry
- Fluid Flow Velocities
- • Pressure Drop Considerations
- Process and Chemical Handling Safety
- Waste Minimization and Disposal
We combine a wide variety of chemicals, including proprietary blends, with techniques such as circulation, fill-and-soak, cascading, foaming, rotating spray systems, and vapor phase cleaning to achieve superior performance and results.
Our services cater to a wide range of heat transfer equipment including: Marine Boilers, Lube Oil Coolers, Condensers, Evaporators, Compressor Jackets, Intercoolers/Aftercoolers, Pump Jackets, Chilled Water Cooling System, VHP Systems, Air Handling & Fan Coil Units, Shell & Tube Heat Exchangers, Double Pipe Heat Exchangers, Plate Type Heat Exchanges, Waste Heat Boilers
The chemical cleaning services include:
Gamma Jet Cleaning
Chemical Cleaning > De scaling >> Pre-Commissioning
Each year millions of rupees are spent by corporations in setting up process plants for oil, gas, chemicals and downstream processing. A major part of this money goes into piping & machinery. To ensure that this equipment and piping perform at its peak it is necessary to start operations on them in a clean condition.
When new equipment is fabricated, erected, or installed, engineers and plant management must concern themselves with deposits that have accumulated on the metal surfaces during construction or with deposits that have been applied in the manner of protective coatings at the mill. These deposits may appear in the form of dirt, weld splatter, iron oxide, paint, lacquer, or oil coatings.
The removal of these deposits from a newly fabricated process system is referred to as pre-commissioning cleaning, because thorough surface cleaning should be performed prior to initial equipment start-up.
Pre-Commissioning cleaning is desirable for several reasons. The most notable is that on the process side deposits can contaminate the product, reduce efficiency through restricting heat transfer, damage delicate or sensitive instrumentation and valves, and aid in accelerating corrosion. Since the unwanted deposits may be of an organic or inorganic nature, the application of a multistep cleaning procedure may be required to ensure removal of all unwanted deposits. Sometimes pre-commissioning cleaning is performed on exterior surfaces strictly for cosmetic purposes.
Steam Generation System, Amine System, Compressor Suction Circuits & Cooling Water systems that include both piping & equipment are normally cleaned before start up.
Spanchem Technologies ensures that the various factors namely the metallurgy being cleaned, type of deposits, mechanical design of the equipment, time & temperature constraints along with safety & disposal considerations are taken into account while formulating cleaning procedures.
We make use of a variety of techniques like dynamic circulation, fill & soak ,cascade cleaning, immersion cleaning, swab cleaning & foaming are used to meet the cleanliness targets set by the end user
Chemical Cleaning > De scaling >> Post-Commissioning
Today, the high cost of energy and downtime (nonproduction hours) is an important factor in considering post-commissioning chemical cleaning of systems or equipment. To minimize operating costs while maintaining high operating efficiency the removal of deposit buildup is essential to equipment life and product quality.
Consequently, the use of post-commissiong chemical cleaning techniques to remove unwanted deposits from the process-side and water-side segments of industrial process equipment are widely employed.
Neglect in removing organic or inorganic deposits on the process or water sides of industrial equipment may result in irrevocable damage to the equipment, leading to costly repairs and premature replacement of portions or the entire unit.
Spanchem Technologies has the ability to deliver customized solutions based on scale type, metallurgy and equipment geometry. The objective being that the customer's equipment is subject to the minimum downtime required for cleaning and restored to maximum possible efficiencies.
Over the years we have cleaned a wide variety of equipment like Shell & Tube heat exchangers, Double pipe heat exchangers, Plate type heat exchangers, Compabloc heat exchangers, Jacketed Vessels, Glass Lined Reactors, Utility boilers, Power Station Boilers, Marine Boilers, Condenser, Intercoolers, Knock out Drums, DG Set Cooling Circuits and have handled a wide range of metallurgies from Carbon Steels to Austenitic Steels, Martensitic Steels, Duplex Steels, Cast Iron, Admiralty Brass, Copper, Zirconium & Titanium.
We also specialize in the cleaning of refinery specific equipment like Packinox Exchangers, Helitowers, Split Feed Exchangers & Breech Lock Exchangers essentially working towards removing process contamination to reduce fouling.
Chemical Cleaning / De scaling >> Foam Cleaning
Foam Cleaning services from Span Chem Technologies clean dirty fin fans/tubes in air fin coolers & air pre heaters that can reduce the cooling efficiency of heat exchangers.
The traditional cleaning method of hydrojetting damages delicate fin fans and collates the debris into the center of the tube stack. With a chemical process, complete removal of dirt, debris and corrosive elements is possible without any damage to the equipment. Our low pressure, high volume cleaning process removes dirt and debris safely and thoroughly. We use environmentally friendly chemical foam that saturates and expands into every crevice of the gaps between the cooler tubes. A low pressure rinse minimizes over-spray and is safe for both workforce and the equipment.
Chemical Cleaning / De scaling >>Gamma Jet Cleaning
Gamma Jet’s rotary impingement tank cleaning machines combine pressure and flow to create high impact cleaning jets clean large tanks and pressure vessels.
Cleaning occurs at the point in which the concentrated stream impacts the surface of the tank. It is this impact and the tangential force that radiates from that point which blasts contaminants from the surface, scouring the tank interior. In conjunction with this impact, the Gamma Jet is engineered to rotate in a precise, repeatable and reliable, 360-degree pattern. This full-coverage, global indexing pattern ensures the entire tank interior is cleaned, every time.
The combination of high pressure and 360 degree coverage of the jets up to a 30 m radius gives us an edge in this business and the use of special chemistries enable us to clean tanks containing pyrophoric deposits as well.
