Indian petrochemical producer Haldia Petrochemicals (HPL) plans to develop a replacement oil-to-chemicals project at Cuddalore in south India's state of Tamil Nadu.

The project are going to be administrated in 2 phases. The first phase will involve developing an ethylene cracker with an expected nameplate capacity of 1.8 million tonne per year. Downstream units include a 271,000 tonne per year butadiene plant, a 650,000 tonne per year high density polyethylene (HDPE) unit, a 650,000 tonne per year linear low-density polyethylene (LLDPE) swing plant, a 1.2 million tonne per year monoethylene glycol line and three polypropylene (PP) units with combined production of 1.7 million tonne per year.

HPL will also build a series of propylene downstream units during the first phase, including a 300,000 tonne per year phenol unit, an 185,000 tonne per year acetone plant and a 150,000 tonne per year isopropanol line.

Feedstock for the cracker will come from its upstream 6.2 million tonne per year, or 46.5 million barrel per year, crude processing unit at the same complex. HPL is additionally expected to import butane and propane to feed into its cracker, in keeping with an announcement submitted by the corporate to the Ministry of Environment, Forest and Climate Change of India in early December.

HPL can develop associate in nursing aromatics plant throughout its second part. The producer aims to build a 1.6 million tonne per year paraxylene plant along with a 1.25million tonne per year purified terephthalic acid unit. The complex will also produce other aromatics products such as benzene and toluene, with expected production capacities of 580,000 tonne per year and 198,000 tonne per year respectively.

The project is estimated to cost Rs 783 billion ($10.48 billion) and is slated to take eight years for completion once HPL receives all statutory consent and clearances from the relevant authorities and departments.

HPL presently owns a cracker at the East Coast of Bharat in Haldia, in the state of West Bengal. The cracker has a nameplate capacity of 700,000 tonne per year of ethylene and 340,000 tonne per year of propylene. Downstream units consist of a 330,000 tonne per year HDPE unit, a 615,000 tonne per year LLDPE swing plant and a 330,000 tonne per year PP line.
