NEW DELHI (ICIS news)--India’s National Fertilizers Limited (NFL) has invited global bids for setting up a 450 tonne/day carbon dioxide (CO2) recovery plant at its Vijaipur ammonia-urea complex in Madhya Pradesh, it said on Friday.

The deadline for the lumpsum turnkey (LSTK) contract is 21 July.

The selected bidder would have to commission the unit within 20 months of award of assignment. The proposed unit would recover carbon dioxide from flue gases discharged by its first ammonia in the atmosphere.

The gas-based complex comprises two ammonia plants each with 1,520 tonnes/day of capacity and two urea plants each wi th 2,620 tonnes/day capacity. Ammonia and carbon dioxide produced from the former units are reacted to produce urea.

NFL is also working on a project proposal to revamp both the ammonia and urea plants to increase capacity and reduce energy consumption.

The complex faces shortages of carbon dioxide, resulting in build-up of ammonia stocks. The carbon dioxide shortage arises due to low carbon content in lean natural gas, which is primarily methane. The company overcomes shortage of carbon dioxide by using naphtha as supplementary feedstock in ammonia plant I.

According to an analyst, the setting up of a carbon dioxide unit would make this project eligible for carbon credits under the clean development mechanism (CDM).
