Innovative compressor design cuts Chinese processing costs

Peter Brotherhood - the Peterborough, UK, based supplier of engineered equipment for the petrochemical and process industries - has won a $2 million (£1.3 million) order to build two innovative compressor packages for a Chinese refinery.

The machines have been ordered by the China Yanshan United Foreign Trade Company for installation at the Beijing Yanshan Petrochemical Group Company at Yanshan near Beijing.

Each package is based around what appears to be a single four-cylinder reciprocating compressor - but two cylinders of each machine will handle hydrogen make-up gas whilst the other two simultaneously handle recycling gas for diesel fuel hydrofining. Each compressor is designed to meet the refinery’s total make-up and recycling gas requirement so that one machine can be operating whilst one is on stand-by, ensuring continuous availability of this critical equipment.

Conventionally this type of requirement would be met with two medium-sized reciprocating compressors to handle make-up gas (one running and one on stand-by) whilst recycling would be achieved with a single centrifugal compressor, backed up with a full set of spares (including a spare rotor).

Opting for Peter Brotherhood’s solution of two large reciprocating compressors, each capable of handling the full make-up and recycling load, has provided a higher level of reliability at a lower initial cost and with lower power demand than the more conventional solution.

The new machines are due to be delivered to China before the end of the year.
