Hindustan Dorr-Oliver Limited
Fertilizers and Chemicals
India is the third largest consumer and producer of fertilizers. Hindustan Dorr-Oliver has installed about 90% of all the phosphatic fertilizer plants on turnkey basis in India. HDO has been a pioneer in the development of continuous process for manufacture of Phosphoric Acid by the wet process. We are also pioneers in setting up high analysis, complex NPK and DAP granular phosphatic fertilizers. HDO introduced the pipe reactor technology in fertilizer plants in India.
DAP / NPK Plant
Bulk of the granular phosphatic fertilizer produced in India comes from plants designed and installed by Hindustan Dorr-Oliver like IFFCO Kandla, Madras fertilizer Limited Chennai, GFCL Kakinada (now CIL), Zuari Industries Limited Goa, EID Parry Chennai (now CIL), Fertilizers and Chemicals Travancore Limited, Udyogmandaletc.
Phosphoric Acid Plant
DO has installed Phosphoric acid plants based on the Dihydrate and Hemi-Dihydrate processes. HDO commissioned the largest phosphoric acid plant, for Paradeep Phosphates Limited.
Pipe Reactor
HDO introduced the Pipe Reactor technology in India. It is an improvement over the conventional slurry process utilized for production of DAP /NPK fertilizers. Its advantages include higher production capacity, reduction in production cost, lower energy consumption and ease of operation.
ANP Granulation Plant
Most ANP plants in India use prilling tower to manufacture Ammonium Nitro Phosphate. But due to the hazardous nature of this process it was Rashtriya Fertilizers and Chemicals (RCF) in Mumbai decided to replace the prilling tower with a granulation plant.
