Al-Jubail Fertiliser Company (Al-Bayroni) has awarded an engineering, procurement and supply contract to the US’ KBR for its ammonia plant in Jubail.

KBR will provide engineering design, procurement and installation support services for an auxiliary boiler for the ammonia plant owned by Al-Bayroni, a subsidiary of Saudi Basic Industries Company (Sabic).

KBR says the plant was originally built in the 1980s utilising its ammonia technology.

In 2000, Switzerland’s Ammonia Casale won a contract to increase the output of the unit which has a design capacity of 1,000 tonnes a day.

The bulk of Al-Bayroni’s ammonia output is used as feedstock for its urea plant.

KBR is the lead project manager on the $22-26bn Ras Tanura refinery upgrade and integrated petrochemicals complex being developed by Saudi Aramco and the US’ Dow Chemical Company.
