Pilot Plant Projects
Novel Process and Application for Polycarbonate
Project Overview: This pilot unit is designed to produce bio-based polycarbonate. Isosorbide, diphenyl carbonate (DPC), and a titanium-based catalyst are charged into a reactor and thoroughly mixed under agitation. The reaction mixture is heated to 228–240 °C and maintained under vacuum conditions (<5 kPa) for 5.0–6.5 hours to complete the polymerization, producing bio-based polycarbonate.
Ethylene Glycol Catalyst Evalution Pilot Plant
Project Overview: This unit is a dedicated pilot facility for the evaluation of ethylene glycol hydrogenation catalysts. It features a single reactor with a catalyst loading capacity of 30 L. The plant is configured with one feed gas stream (a hydrogen/DMO mixture) and a nitrogen purge stream. The reactor operates at temperatures ranging from 180 to 230 °C (design temperature: 250 °C) and pressures from 2.5 to 3.3 MPaG (design pressure: 3.8 MPaG)).
Organic Sulfur Removal Pilot Plant
Project Overview: This unit is a dedicated pilot facility for evaluating adsorbent performance in the removal of organic sulfur from blast furnace gas and coke oven gas. It is equipped with four adsorption towers—three operating in adsorption mode and one in desorption mode—each with an adsorbent loading capacity of 360 L. The plant is configured with two feed gas streams: one for blast furnace gas and one for coke oven gas. The adsorption towers operate at temperatures ranging from 50 to 250 °C (design temperature: 265 °C) and pressures from 15 to 35 kPaG (design pressure: 38 kPaG).
Methanol Catalyst Evaluation Pilot Plant
Project Overview: This unit is a dedicated pilot facility for evaluating methanol synthesis catalysts. It is equipped with two reactors—a tubular heat exchanger reactor and a radial flow reactor—arranged in parallel, each with a catalyst loading capacity of 300 L. The plant is configured with two feed gas streams: circulating gas from the synthesis loop and fresh synthesis gas, allowing precise control of the hydrogen-to-carbon ratio at the reactor inlet. The reactors operate at temperatures ranging from 190 to 290 °C (design temperature: 330 °C) and pressures from 5 to 8 MPaG (design pressure: 8.9 MPaG).
Multi-Functional Polymerization Pilot Plant
Project Overview:This multi-functional polymerization pilot plant is equipped with multiple reactors, designed to replicate and optimize the configuration and operation of full-scale commercial units. It enables efficient scale-up from laboratory and pilot studies to commercial production. The facility offers flexible operation and a comprehensive setup, supporting both single-reactor copolymerization and multi-reactor hybrid polymerization under a wide range of process conditions, while ensuring reliable data collection and validation.
