Worlds Largest LNG Plant in Malaysia Requires Over 90 Valves

A nearly $6 million contract for 30 anti-surge control valves, 34 depressurizing valves, and 30 valves for flares and pressure control services has been awarded to CCI by consortium made up of JGC Corporation, Kellogg Brown & Root, Inc., JGC (Malaysia) Sdn. Bhd., Kellogg (Malaysia) Sdn. Bhd., and Sime Engineering Sdn. Bhd., for the project Malaysia LNG Tiga Bhd. Sdn. This is phase three of the Malaysian LNG production complex, which will make the complex the single largest in the world when completed.

The two new LNG trains involved here will produce 7,600,000 metric tons/year of LNG; total plant size will then be 23,000,000 metric tons/year – the world’s largest single LNG project.

Among the 30 DRAG® anti-surge valves that range in size from four inches (100 millimeters) to 32 inches (800 millimeters), flows range up to 529 pounds/second (236 kilograms/ second) at inlet pressures to 1160 psia (80 BarA) and pressure differentials to 1150 psi (79 Bar) and at temperatures ranging to 205 F (96 C). In this service, the requirement of sound-power levels of < 83 + 0 dBA is attained by using CCI DRAG® multi-stage technology.

In addition, all 30 anti-surge valves feature a stroke speed requirement of < one second using exclusively pneumatic actuators, including the large items. This latest requirement is attained using CCI’s unique engineering expertise in pneumatic controls, which is backed up by years of proven experience in the field and by numerous installations with such demanding performances. For some of the items additional cryogenic requirements applied.

In the 34 depressurizing service valves that range in size from three inches (75 millimeters) to 12 inches (300 millimeters), flows range up to 399 pounds/second (139 kilograms/second) at pressures of 972 psia (67 BarA) inlet and 930 psi (64 Bar) differential and at temperatures ranging as low as 188 F (–122 C).

This order is particularly significant because it represents a recognition of the superior control capability, historic reliability, and product flexibility and rangeability of the DRAG®’s unique multi-stage, pressure and noise reduction technology, as well as other advanced control valve technologies unique to CCI.

This project re-establishes CCI and its DRAG® multi-stage technology as the major worldwide supplier of severe service control valve applications and solutions for LNG plants.
