MOSCOW (MRC) -- Honeywell announced that Zhejiang Satellite Petrochemical Co., Ltd. is using a Honeywell UOP Polybed pressure swing adsorption (PSA) unit to supply high-purity hydrogen to its integrated refining and petrochemicals complex in China, as per Hydrocarbonprocessing.
The PSA unit purifies hydrogen generated by its UOP C3 Oleflex propane dehydrogenation unit.
Zhejiang Satellite, which recently announced a second C3 Oleflex unit to meet the growing propylene demand in China, has used the PSA technology to upgrade the purity of hydrogen to meet refining needs. In addition to technology licensing, Honeywell UOP, a technology leader in the oil and gas industry, provided services, equipment, catalysts and adsorbents for the Satellite plant.
“In the last five years, we’ve worked with Zhejiang Satellite to construct new petrochemicals facilities centered around our Oleflex technology, which helped to maximize operating flexibility and onstream reliability,” said Bryan Glover, vice president and general manager, Petrochemicals & Refining Technologies at Honeywell UOP. “Their selection of our PSA technology further enhances the reliability of their operations and provides a steady, stable source of high-purity hydrogen.”
The PSA process uses proprietary UOP adsorbents to remove impurities at high pressure from hydrogen-containing process streams, allowing hydrogen to be recovered and upgraded to more than 99.9% purity to meet refining needs.
In addition to recovering and purifying hydrogen from steam reformers and refinery off-gases, the Polybed PSA system can be used to produce hydrogen from other sources such as ethylene off-gas, methanol off-gas and partial-oxidation synthesis gas. Polybed PSA systems are skid-mounted, modular units complete with hardware, adsorbents, control systems and embedded process technology, enabling quick and efficient installation to reduce cost and downtime.
Since its introduction in 1966, UOP has improved Polybed PSA technology with new generations of adsorbents, enhanced cycle configurations, modified process and equipment designs and more reliable control systems and equipment. Today, Honeywell UOP has installed more than 1,100 Polybed PSA units in more than 70 countries. As a result, Polybed PSA is a proven technology with dozens of large-scale unit references globally.
As MRC reported earlier, in August 2019, Honeywell announced that PetroChina Guangdong Petrochemical Company will adopt advanced heavy oil processing technology from Honeywell UOP for its integrated petrochemical complex in China. The new facility will have an annual crude processing capacity of 20 million tons, helping to meet a national energy security strategy while transforming PetroChina Guangdong into a more fully integrated petrochemicals supplier.
Ethylene and propylene are feedstocks for producing polyethylene (PE) and polypropylene (PP).
According to MRC's ScanPlast report, Russia's estimated PE consumption totalled 557,060 tonnes in the first three month of 2020, up by 7% year on year. High density polyethylene (HDPE) and linear low density polyethylene (LLDPE) shipments rose because of the increased capacity utilisation at ZapSibNeftekhim. Demand for LDPE subsided. At the same time, PP shipments to the Russian market was 267,630 tonnes in January-March 2020, down 20% year on year. Homopolymer PP and PP block copolymers accounted for the main decrease in imports.
