Incinerators for Animal Waste, Biomedical Waste, Solid watse,  Liquid Waste

Introduction :

Incineration is a waste treatment process that involves the combustion of organic substances contained in waste materials. Incineration and other high-temperature waste treatment systems are described as 'thermal treatment'.Incineration of waste materials converts the waste into ash, flue gas, and heat.

Synchronous International Engineering Solutions Co. Ltd.(SIES) is one of the leading suppliers of Incinerators & Pet Cremators. Our Principals has over two decades of experience and expertise in the field of Combustion technology. One of the main feature of our Incinerators range is that they burn virtually smoke and smell free without the need for a secondary burner because of their advanced internal design.

Special Features

  • Quick heat up times.
  • Virtually smoke & smell free.
  • No power Consumption.
  • High temperature & Burn rate.
  • Quick Installation and Maintenance.

H2S Gas Scrubber, Ammonia Gas Scrubber, Toxic Gas Scrubbers


For the utilization of Biogas it is essential to remove its toxic elements viz. H2S, Ammonia etc. Biogas Scrubbers are used for removal of these constituents.

Absorption is basic chemical engineering operation and is most preferred and well established gas pollution control technique.

Biogas scrubber based on chemical Treatment (NaOH, KOH etc.) is very popular and well proven method of scrubbing of biogas. Their advantages are unparalleled as compared to other scrubbing methods.

The Biogas is first washed in Venturi to remove the suspended particles/foam etc, further it goes to packed tower for Chemical Treatment. The Scrubber is so designed that the spent Lye is used to the maximum possible extent resulting in very low caustic consumption and estimated saving of 25-50% can be achieved depending upon Biogas Composition and H2S levels.

CRA has developed the scrubbing process so that there is minimum consumption of chemical for Scrubbing by utilizing the spent chemicals.


ü  Skid mounted modular designs with compact footprints

ü  Selective Absorption of H2S.

ü  Quick start process, no lag time.

ü  Venturi Sizing optimized to increase contact time with H2O & increase efficiency.

ü  Multiple stages also available as per H2S Levels.

ü  NaOH is reutilized as spent Lye thus reducing chemical consumptions by 25-45%.

ü  Instant start and stop of scrubbing

ü  Scrubbed gas (sweet gas) available almost instantly as soon as the scrubbing starts.

ü  Customized Systems for different levels of H2S.
