Sarens assists with renovation of Hengyuan Refinery's oil plant

Sarens replaced the E451 heat exchanger with a new unit. For this task, Sarens engineers selected the Liebherr LR750 crane because of its high lifting capacity, with up to 750 t of maximum load, in environments with limited space.

Hengyuan Refining's oil plant currently has the capacity to produce up to 156 000 bpd of petroleum products and is one of the largest in Malaysia. It is one of the oldest in the region as the company was founded in 1960 and started operations in 1963. The plant has a broad product portfolio that includes LPG, jet fuel, gasoline, diesel, sulfur, fuel oil components, and chemical feedstocks such as light naphtha and propylene.

The crane used by Sarens was moved from the Sungai Besi-Ulu Kelang Elevated Expressway (SUKE) project in Kuala Lumpur to Port Dickson, in a logistical operation that required 22 low-floor trailers. The machinery was working at the plant for approximately one month, including crane erection.

The main challenge of the operation was the limited space where the lifting work was required. The site was very crowded and left little room for the crane to manoeuvre. Therefore, the decision was made to use the LR750 model with crane configuration that would be 77 m main boom with SDBW configuration.

Sarens Project Manager for this replacement work, Chaini Mos, explained the main tasks to be performed: “The lifting radius would be approximately 48 m, and the total weight of the equipment to be lifted is 110 t, excluding the mounting accessories and the hook pulley, and the main limitation was space. But with the LR750 and its operability we managed to replace the heat exchanger successfully within the established time frame.”

The refinery's main operating units consist of two crude distillers, a long residue catalytic cracker (LRCCU), two naphtha treaters and a merox plant, two reformers and a gas oil treatment plant.

Approximately 85% of the refinery’s products are sold in Malaysia, mainly through three channels: the multi-product pipeline to the Klang Valley and KLIA, its truck loading gantry for local customers (West Malaysia), and the export of products to ships through its jetty to East Malaysia and overseas markets.
