About YEMCL - Industrial Machinery Supplier in China

China hosts the supplier YEMCL, which currently lists eight active products across industrial and light‑medium machinery, crude oil processing, bitumen and asphalt production, and oil‑field equipment. The catalogue comprises a hydrogen generation system, an industrial chemical gas treatment unit, a crude oil refinery line, a bitumen & asphalt production line, a customized herb extraction plant, an oxidation‑modified bitumen/SBS production line, a distillation column and oil fractionating unit, and an essential oil distillation plant. These items are typically classified under HS chapter 84 (machinery) and chapter 85 (electrical machinery) for customs purposes. YEMCL’s trust tier is recorded as “harbor”, indicating a mid‑level verification status on the platform.

The eight offerings cover both large‑scale process plants and smaller specialised units. Heavy‑duty items such as the crude oil refinery and bitumen production line are designed for throughput measured in barrels per day or tons per hour, while the hydrogen generation system and gas treatment unit are sized in normal cubic metres per hour (Nm³/h). The herb extraction and essential oil distillation plants are usually built with stainless‑steel sanitary components and operate at batch capacities ranging from 100 kg to several tonnes per cycle. All products are presented as turnkey solutions that can be integrated into existing industrial sites.

Product Range and Specialties of YEMCL

YEMCL’s catalogue presents a hydrogen generation system that commonly employs PEM or alkaline electrolyzers with capacities between 10 Nm³/h and 500 Nm³/h, meeting IEC 62282 standards for safety. The industrial chemical gas treatment unit typically includes adsorption, catalytic conversion, or scrubbing stages and is engineered to handle flow rates of 1 000 Nm³/h to 10 000 Nm³/h, with material selections such as 316L stainless steel for corrosion resistance. The crude oil refinery line is usually specified by daily processing capacity (e.g., 5 000 bbl/d to 20 000 bbl/d) and conforms to API 650 tank standards and API 610 pump specifications. Bitumen & asphalt production lines are rated in tons per hour (often 10‑50 t/h) and follow ASTM D946 for bitumen quality. Customized herb extraction plants and essential oil distillation plants are designed for batch or continuous operation, with typical column heights of 5‑15 m and operating pressures up to 5 bar, adhering to GMP guidelines for food‑grade processing. Distillation columns and oil fractionating units are sized by number of theoretical plates (10‑30 plates) and are fabricated to meet ASME Section VIII pressure vessel codes.

Trade and Export Information - YEMCL

China remains one of the world’s largest exporters of process machinery, with the majority of shipments destined for Southeast Asia, the Middle East, Africa, and Latin America. Buyers of refinery, bitumen, and oil‑field equipment typically request compliance with ISO 9001 quality management, API specifications (e.g., API 610, API 650), and CE marking for equipment destined for EU markets. HS codes in the 8429‑8429.99 range cover oil processing equipment, while 8479‑8479.99 covers other specialized machinery. Export logistics commonly use 20‑ft or 40‑ft containers for modular plant sections, and heavy units are shipped on roll‑on/roll‑off vessels or flat‑rack containers. Incoterms such as FOB Shanghai or CIF Dubai are standard in the industry, with buyers often arranging on‑site installation and commissioning services.

Typical importers of the listed product categories include petrochemical refineries, construction material producers, agricultural processing firms, and oil‑field service companies. Chinese manufacturers of such machinery benefit from a mature supply chain for steel, instrumentation, and control systems, allowing lead times of 8‑12 weeks for standard designs and 16‑24 weeks for fully customized plants. Export documentation generally includes a commercial invoice, packing list, bill of lading, certificate of origin, and, where required, an IECEx or ATEX certificate for explosion‑prone environments.

Sourcing from YEMCL - Buyer Guidance

When sourcing from YEMCL, buyers should request detailed technical datasheets that specify design capacity, material grades (e.g., 304/316L stainless steel, carbon steel), power consumption, and applicable standards such as IEC, API or ASTM. Performance test reports, such as hydrogen production efficiency (kWh/Nm³) or bitumen viscosity (cSt at 60 °C), help verify compliance with industry benchmarks. Buyers are advised to obtain a copy of the supplier’s ISO 9001 certificate and, for equipment intended for EU markets, a CE Declaration of Conformity. Prior to order confirmation, verify the HS code classification that will be used for customs clearance and ensure the plant’s dimensions fit the intended shipping container or vessel type.

Sample units are rarely provided for large‑scale plants, but YEMCL can supply a functional prototype or a 1:10 scale model for critical components such as the hydrogen electrolyzer stack or a distillation column tray. Minimum order quantities depend on the plant size; typical turnkey projects start at a base capacity of 10 Nm³/h for gas systems or 5 t/h for bitumen lines. Lead time estimates should be confirmed in writing and include allowances for civil works, utility connections, and local permitting.

What types of hydrogen generation systems does YEMCL offer?

YEMCL lists a hydrogen generation system that can be configured with PEM or alkaline electrolyzers, with capacities ranging from 10 Nm³/h up to 500 Nm³/h and complying with IEC 62282 safety standards.

Can YEMCL provide a gas treatment unit for industrial chemical processes?

Yes, the industrial chemical gas treatment unit is described as a modular system handling flow rates between 1 000 Nm³/h and 10 000 Nm³/h, built with corrosion‑resistant stainless‑steel and designed to meet typical adsorption or catalytic conversion specifications.

What is the typical capacity of the crude oil refinery line offered?

The catalogue cites a crude oil refinery line that can be specified for daily capacities from roughly 5 000 bbl to 20 000 bbl, with equipment designed to API 650 tank and API 610 pump standards.

Which standards are commonly required for the bitumen & asphalt production line?

Bitumen and asphalt lines are usually required to meet ASTM D946 for bitumen quality, and buyers often request compliance with ISO 9001 quality management and local emission regulations.

What documentation should a buyer request before purchasing the herb extraction plant?

Buyers should ask for a technical datasheet, material certification (e.g., 316L stainless‑steel), GMP compliance statement, and any relevant ISO or CE certificates that confirm food‑grade suitability.

What are typical shipping methods for YEMCL’s heavy machinery?

Large modules are typically shipped on flat‑rack containers or as break‑bulk cargo on roll‑on/roll‑off vessels, with Incoterms such as FOB Shanghai or CIF Dubai commonly used.

Is a sample or prototype available for the essential oil distillation plant?

YEMCL can provide a scaled‑down prototype or a functional demo of key components, such as a distillation column tray, to allow performance verification before full‑scale order.

What certifications are generally expected for oil‑field equipment exported from China?

Buyers usually require ISO 9001 quality certification, API equipment specifications, and, where applicable, CE marking or IECEx/ATEX certification for explosion‑prone environments.
