The Q-Chem II Project is a joint venture between Qatar Petroleum (51 percent) and Chevron Phillips (49 percent).

It is an expansion of the Q-Chem complex that was launched in May 1997 in Mesaieed Industrial City to produce a range of petrochemicals, including sulphur (36,000 tonnes per annum), ethylene (500,000 t/a), 1-hexene (47,000 t/a) and high density polyethylenes (453,000 t/a).

The Q-Chem II Project includes a new 350,000 t/a high-density polyethylene plant and a 345,000 t/a normal alpha olefins plant. 

Another aspect of the Q-Chem II project is the joint venture Ras Laffan Olefins Company (RLOC), a 1.3 million t/a ethylene cracker in the Ras Laffan Industrial City operational from May 2010.

The Q-Chem II companies have a 53.85% capacity share of the ethylene cracker. The additional capacity of the ethylene cracker will be owned by Qatofin, which is a venture between Qatar Petroleum (1%), Qatar Petrochemical Company Ltd (QAPCO) (63%) (Qatar Petroleum owns 56% of QAPCO), and Total Petrochemicals (36%).

The new ethylene cracker provides feedstock via a new 120km-long pipeline to the Q-Chem II complex and to Qatofin's new 450,000mtpa linear-low-density polyethylene unit.
