With domestic refineries scaling up their polypropylene lines, securing propylene feedstock has become a bottleneck. The incremental output from traditional FCC off-gas is capped by crude throughput and process limits, so it can no longer keep pace with polyolefin expansion.

Propane dehydrogenation (PDH) has therefore moved into the spotlight: imported propane is converted to polymer-grade propylene in a single pass with high selectivity, plus a bonus stream of low-cost hydrogen. Its cash cost tracks almost one-for-one with the propane price, so the profit window is simply the “propane–propylene” spread. Producers can flex storage positions around that spread, hedge volatility and lock in predictable margins.

The reformer is the refinery’s “oil-chemicals-H₂ triangle hub”: a continuous catalytic system that turns low-octane naphtha into high-octane gasoline, aromatics and low-cost hydrogen in one step.

In the low-carbon oxygenated-fuel arena, “internally oxygenated” alcohols serve as the hub, merging “bio-carbon” and “C1 chemistry” into one track: fuel ethanol fixes CO₂ via photosynthesis, while methanol reforms CO₂/CO with green H₂ or syngas—two routes that converge to deliver high-octane, low-PM combustion for road, marine and aviation engines and that plug seamlessly into biomass, green hydrogen and CO₂ capture, forming a universal liquid carrier for decarbonizing both transport and chemical value chains.

Focused on the deep split-up and purification of the C₆ fraction from reformer tops, hydrotreated light naphtha or cracked light gasoline.

By ultra-close-cut distillation, adsorptive separation or isomerisation–distillation hybrids, the unit reliably delivers:
- 99.5 % n-hexane (polymerisation solvent)
- High-octane iso-C₆ (clean-gasoline blendstock)
- 1-hexene (LLDPE co-monomer)
- Cyclohexane and benzene (building blocks)

The same platform also handles vacuum de-acid/colour removal from C₆ diols (CHDM, HDO), feeding high-purity streams to polyurethane and plasticiser chains.

As a key "less fuel, more chemicals" enabler, C₆ upgrading is continuously scaled up and energy-optimised.

A generic term for synthetic resins produced by polymerizing olefin monomers such as ethylene and propylene; it comprises mainly polyethylene (PE), polypropylene (PP) and polybutene (PB). With the largest global output of any polymer family—about 65 % of total plastics consumption—olefin-based resins are used in packaging, agriculture, automotive, appliances, construction, medical devices, electronics and electrical applications.

Coatings sit at the intersection of chemicals and materials; their core job is to give metal, wood, concrete or plastic surfaces protection, decoration and advanced function.

Split by end-use, the sector covers architectural, industrial, anti-corrosive, automotive, wood, powder and coil coatings. Film-formers are being switched to water-borne, high-solid, solvent-free, powder and UV-curable systems to cut VOC. The global market will be about USD 220 bn in 2025; China accounts for 33 % and grows 5–6 % yr⁻¹.

Functional trends (self-cleaning, heat-reflective, antimicrobial, conductive, intumescent) run in parallel with green manufacture (bio-based resins, water-borne epoxies, solvent-free PU). Up-stream the industry is locked to acrylics, epoxies, polyurethanes, TiO₂ and additives; down-stream it feeds trillion-dollar markets such as construction, automotive, marine, wind power and home appliances—making coatings a classic “small-tonnage, high-value” segment of the chemical chain.

The refrigerant field is the "invisible bloodline" of the temperature control industry chain, providing heat transfer working fluids for air conditioners, refrigerators, automotive air conditioners, and cold chains, and extending to emerging scenarios such as liquid cooling and energy storage thermal management in data centers, supporting global temperature control demand.

By cryogenically liquefying and distilling inexhaustible air, we tear out oxygen, nitrogen and argon by the ton, along with the rare gases krypton, xenon, neon and helium—the “industrial lungs” that keep modern steel, chemicals, energy, electronics, healthcare and aerospace alive.

The mixed gas composed of CO and H₂ in different proportions is known as the "crossroads of carbon-1 chemical industry".

It integrates coal, petroleum coke, natural gas, biomass, industrial exhaust, and even CO₂ and green hydrogen into the same platform, providing direct access to almost all basic chemicals and fuels such as hydrogen, methanol, ammonia, gasoline and diesel, aviation kerosene, olefins, aromatics, ethylene glycol, etc. It is the "central hub" for the integrated transformation of energy and chemical industry.

In the field of natural gas purification, we specialize in segmenting and removing impurities such as hydrogen sulfide, CO ₂, water, heavy hydrocarbons, and mercury from crude natural gas at wellhead to meet pipeline transportation, liquefaction, or chemical feed standards.

After purification, the gas can safely enter LNG, ethane cracking, blue hydrogen, and synthetic ammonia facilities, which are essential links connecting gas production and high-end utilization.

Clean energy hydrogen production, using wind, solar, or biomass as energy sources, electrolyzing and reforming pure water or renewable carbon sources into hydrogen gas, with nearly zero emissions throughout the entire process; The purity of the produced green hydrogen reaches 99.999%, which can directly drive fuel cells, green steel, synthetic ammonia, methanol, and aviation fuels. It spans across the three decarbonization scenarios of electricity, industry, and transportation, and is moving from demonstration to a million ton base, becoming the "ultimate secondary energy" in the era of carbon neutrality and the central converter for green transformation of energy systems.

Electronic gases are the “blood” of advanced manufacturing—semiconductors, displays, photovoltaics. The family splits into bulk gases (N₂, Ar, etc., 5–6 N) and more than 260 specialty gases (SiH₄, PH₃, CF₄ …) used for doping, etch, deposition and lithography. Once nodes shrink to 7 nm, control of metals, moisture and particles jumps from ppb to 0.01 ppb.
