Pre-Operational & Post-Operational Boiler, Process Plant Chemical Cleaning, Plant Turnaround Decontamination / Degassing and Fuel Oil Additive Treatment Services for the Power Generation, Petroleum Refining, Chemical Manufacturing, Gas Processing and Steel Manufacturing Industries.
VERChem's Company Background
VERChem's operation in Singapore has evolved from being a Dowell Schlumberger location to becoming a HydroChem Branch office following the acquisition of the industrial services division of Dowell Schlumberger by HydroChem and subsequently to VERChem following the acquisition of HydroChem's Singapore branch office's operating assets in 2003 and continues to offer safe and quality chemical cleaning, decontamination and fuel oil additive services to our valued customers.
We maintain our historical ties with HydroChem through a Technology Licensing Agreement and acts as HydroChem's Exclusive Sales Agent in the Asia Pacific Region.
Exclusive Sales Agent for HydroChem's Tank Cleaning and Pre-commissioning Services including SilentSteam™ Blow Process in the Asia-Pacific Region
VERChem® is the exclusive sales agent for HydroChem's Pre-commissioning Services including their SilentSteam™ Blow Process for superior and faster cleaning of steam system components. Advantages of SilentSteam™ Blow Technology includes the following:
SilentSteam™ Blow produces CFRs of greater >1 .... continuously at high velocity and low pressure.
Does not require temperature and pressure cycling of steam system being cleaned thereby eliminating stresses associated with these practices.
"Silent" because blowing noise levels is 80 dB and below at 100 ft from the steam outlet. The low noise level as compared to conventional exhaustic blow techniques will not disrupt other site activities and surrounding communities.
Shorter Cleaning Time allowing faster and trouble-free start-ups.
Foam Cleaning Service for Condensers, Steam Turbines and Gas Turbines
Condenser with its many tubes are best cleaned using chemical foam. Chemical foam cleaning allows a condenser to be cleaned within a 24 hours period, this condenser cleaning time is not possible with HP water jetting or other mechanical cleaning methods. The newly cleaned condenser tubes allow the plant owners to restore the overall efficiency of the condenser. Condenser foam cleaning technology have also been applied sucessfully for the cleaning of steam turbine and gas turbine.
With foam cleaning, steam turbine and gas turbine can be cleaned in-situ without disassembly, effectively recovering lost output without lengthy downtime. Small amount of copper deposits in the high-pressure section of steam turbine can caused major loss in MW output. These deposits in the past can only be remove by grit blasting during the 5 yearly turbine outage, with foam cleaning technology, the MW losses can be easily recovered over a weekend outage. For gas turbine, current practice of on-line washing is effective only for the first few row of blades before centrifugal forces throws off the cleaning fluid leaving not contact between fluid and blades, with foam cleaning technology, all section of the compressor can be effectively cleaned ensuring complete removal of the deposits and restoring turbine performance.
Pre-Operational and Post-Operational Chemical Cleaning of Boiler, Process Piping for Refinery, Chemical Manufacturing and Gas Plant
VERChem has extensive experience in pre-commissioning boiler chemical cleaning, post-operational boiler chemical cleaning, process piping chemical cleaning and lube oil system oil flushing. Type of boiler design and process plant cleaned:
Drum Type - Natural and Forced Circulation Boiler, Once-Through, HRSG & Combined Cycle units.
Ethylene Plant, Olefins Plant, Chemical Plant. - Process Piping, Compressor Suction lines, Steam System, furnace.
Gas Plant - CO2 Removal System, Acid Gas Removal System.
Steelmill - Hydraulic and Lube Oil System cleaning and flushing.
Papermill.
Pharmaceutical Plant - Ultrapure Water System.
Refinery, Ethylene, Olefins and Chemical Manufacturing Plant Turnaround Decontamination / Degassing Products & Services
VERChem's decontamination / degassing procedures using HydroChem's EZE-Clear™ and EZE-Rinz™ CFE Controlled Breakout Detergent can effectively allows plant Turnaround Team to carryout decontamination / degassing of columns, towers, heat exchangers and process piping in the shortest time possible when compared to convention steam purging procedure thereby saving valuable downtime allowing more time for turnaround downstream maintenance activities or earlier start-up of the plant.
EZE-Clear™ is effective for a wide hydrocarbon range. Application of EZE-Clear™ and EZE-Rinz™ CFE line of products is also versatile and decontamination can be carried out simultaneously as a liquid phase circulation for the pipings/heat exchangers and by steam fogging for the column/tower. Achieve benzene and LEL targets in less than half the time it takes to clear the equipment with steam purging.
Pre-Operational, Post-Operational Chemical Cleaning, Plant Turnaround Decontamination/Degassing Project Site Management
Just as important as other aspects of the chemical cleaning project and plant turnaround decontamination process is the quality of the site management and execution team in ensuring the successful execution of the cleaning plan; this can come only with experience, understanding of the cleaning requirement and the HS&E considerations of the entire cleaning project.
Please call us, we can assist you achieve the objectives of your chemical cleaning project with the right chemistry, procedure, on schedule and within budget!
