The aim of this project is to reduce nitrous oxide (N2O) emissions in the tail gas of the nitric acid plant of Pakarab Fertilizer Ltd. N2O is an undesired by-product in the production process of nitric acid, which was normally released to the atmosphere.
To avoid this, the plant has been retrofitted with a tertiary N2O abatement unit in the tail gas stream. The unit reduces the vast majority of N2O at the source, before it would be released to the atmosphere. Other project benefits include the preservation of the ozone layer and helping spread green technology worldwide:
Before the existence of the Kyoto Protocol there was no worldwide regulation of N2O emissions from the nitric acid industry. There is no financial incentive for plant operators to reduce N2O without revenues from the sale of CERs.
The flexible mechanisms of the Kyoto Protocol provided market incentives to implement reduction technology in many plants around the world. It has made nitric acid projects a clear success story of the Kyoto Protocol. It shows that market incentives are an effective tool that can lead to real, permanent, measurable, verifiable and additional reduction of greenhouse gases, which have otherwise not occurred.
