NOVA Chemicals has reported a net income of $51m in the second quarter of 2010, rising from a net loss of $83m during the same period last year.
The company's olefins / polyolefins business unit reported a profit of $251m in Q2 compared to $81m in the corresponding period in 2009.
The company has attributed the growth to an increase in selling prices and improved demand.
In July, NOVA signed an agreement with Hess Corporation and Mistral Energy to purchase and transport ethane production from Hess' Tioga Gas Plant in North Dakota.
