Model Answer
Petroleum refinery is called a 'nodal industry' because it acts as a central hub supplying raw materials to several other industries:
- Petrochemicals produced by oil refineries are the key raw materials for manufacturing synthetic fibres (polyester, nylon) and synthetic rubber.
- Petrochemicals also supply inputs for the fertiliser industry, supporting agricultural production.
- They further provide raw materials for plastics, dye-stuffs, drugs and pharmaceuticals, making refineries central to numerous chemical industries.
Thus, without petroleum refining, these dependent industries cannot function, justifying the term 'nodal industry.'
