Chinese operator lets contract to double capacity of PDH plant

Zhejiang Satellite Petrochemical Co. Ltd., also known as Zhejiang Satellite Energy Co. Ltd., has let a contract to Germany’s Siemens AG to supply a reactor effluent compressor train for the second phase of its propylene dehydrogenation (PDH) plant in Pinghu City, Zhejiang Province, China.

Zhejiang Satellite Petrochemical Co. Ltd., also known as Zhejiang Satellite Energy Co. Ltd., has let a contract to Germany’s Siemens AG to supply a reactor effluent compressor train for the second phase of its propylene dehydrogenation (PDH) plant in Pinghu City, Zhejiang Province, China.

As part of the order, Siemens will deliver two of its proprietary STC-SH single-shaft compressors as well as a 41-Mw Siemens SGT-750 industrial gas turbine to drive the dual-casing compressor train, which is scheduled for installation in late 2018, the service provider said.

Due to be commissioned in early 2019, Satellite Energy’s Phase 2 PDH plant will mark the first downstream commercial application of the SGT-750 gas turbine, which alongside its optimized design for direct drives without intermediate gears and rotational speed of 6,100 rpm, also enables operators to extend intervals between maintenance events to help increase production uptime as well as reduce lifecycle costs, Siemens said.

This latest contract for the Phase 2 PDH plant follows Satellite Energy’s award to Siemens in 2013 for the project’s first-phase compressor train, for which Siemens supplied two of its proprietary STC-SH (14) compressors and a SGT-700 gas turbine.

Under construction since 2016, Satellite Energy’s Phase 2 PDH plant will be able to produce 450,000 tonnes/year of propylene and 300,000 tpy of polypropylene, according to separate releases from the Pinghu Municipal Government and Sinopec Ningbo Engineering Co. Ltd., which completed work on the project.

Commissioned in 2014, Phase 1 of Satellite Energy’s PDH plant produces 450,000 tpy of propylene from propane using Honeywell UOP LLC’s proprietary C3 Oleflex process technology, according to a Dec. 23, 2014, from UOP.
