Customer Background

GEA / BASF — BPC Lemongrass is a recognized participant in the industrial gas and specialty chemicals sector based in Malaysia. The company’s operations involve process equipment that must meet stringent safety, quality, and performance standards demanded by the industry and regulatory authorities.

This project required ASME+DOSH Refrigeration Vessels engineered to ASME standards using SA516 Gr.70, reflecting the technical demands of the application and the client’s commitment to equipment reliability and regulatory compliance.

Challenges and Engineering Requirements

Process Temperature Control in industrial gas and specialty chemicals

GEA / BASF — BPC Lemongrass required precise low-temperature cooling for ASME+DOSH Refrigeration Vessels service in the industrial gas and specialty chemicals sector. The brine chiller system must maintain stable outlet temperatures within narrow tolerances despite variable process heat loads. Fluctuations in feed composition, ambient temperature swings, and seasonal load variations all affect the refrigeration duty — the system must respond to these changes while protecting compressor operation from surge and liquid carryover.

Refrigerant Selection and Safety

The choice of the selected refrigerant reflects the balance between thermodynamic efficiency at the target evaporating temperature, compatibility with the plant’s existing refrigerant infrastructure, and safety classification under the applicable code. Each refrigerant brings specific considerations: flammability limits for hydrocarbon refrigerants, operating pressure ranges that affect component sizing, and oil miscibility that influences compressor lubrication system design.

Integration with EPC Engineering

The chiller packages were specified and documented by the project EPC/design institute as part of a larger process unit. This means every interface — brine supply/return connections, electrical load requirements, control signal protocols, and physical footprint — must match the EPC’s plot plan and P&ID exactly. Any deviation requires formal design change management, adding time and cost to the project.

Why GEA / BASF — BPC Lemongrass Selected Lmart

Integrated refrigeration package capability. Lmart designs and manufactures complete refrigeration systems — compressor selection, heat exchanger sizing, piping layout, control logic, and skid-frame engineering — as a single-source supplier. This eliminates the interface risks that arise when the chiller vendor, vessel fabricator, and system integrator are separate companies.

Process refrigerant experience. Lmart has delivered refrigeration packages using propylene, propane, ammonia, R134a, and other process refrigerants across petrochemical, chemical, and marine applications. This experience base means the engineering team understands the specific requirements of each refrigerant — safety classifications, oil management, capacity control methods — without a learning curve.

Repeat performance. Lmart has delivered equipment to GEA / BASF — BPC Lemongrass and similar clients in the industrial gas and specialty chemicals sector, demonstrating consistent quality and on-time delivery performance across multiple projects.

Engineering and Manufacturing Solution

Lmart engineered and fabricated ASME+DOSH Refrigeration Vessels for GEA / BASF — BPC Lemongrass to ASME using SA516 Gr.70. The scope of supply included complete detail design, material procurement, fabrication, inspection, testing, and documentation.

Key engineering considerations for this project included thermal-hydraulic performance optimization, material selection for the specific process environment, and compliance with ASME requirements for design, fabrication, and inspection.

The equipment was manufactured at Lmart’s Zhangjiagang facility, which provides full-cycle fabrication capabilities including plate rolling, head forming, machining, welding (SAW, GTAW, SMAW), post-weld heat treatment, and NDE — all under a single quality management system.

Quality Control and Project Execution

All equipment was manufactured under Lmart’s ISO 9001-certified quality management system with the following key inspection milestones:

• Material verification: Incoming inspection of all plates, forgings, and fittings against mill certificates; PMI spot checks on alloy materials
• Welding quality: All welding performed by qualified welders using approved WPS/PQR; NDE per ASME requirements including RT/UT on pressure-retaining welds
• Dimensional inspection: In-process dimensional checks at shell rolling, head forming, and final assembly stages
• Pressure testing: Hydrostatic test to ASME requirements, witnessed by the authorized inspector and/or client representative
• Documentation package: Complete data book including material certificates, weld maps, NDE reports, dimensional records, and test certificates

Equipment was delivered to GEA / BASF — BPC Lemongrass’s project site in Malaysia, meeting the project schedule requirements.

Results and Business Impact

Lmart successfully delivered 4 units of ASME+DOSH Refrigeration Vessels to GEA / BASF — BPC Lemongrass, meeting the project’s quality, schedule, and documentation requirements. The equipment was manufactured in SA516 Gr.70 to ASME standards, with full documentation packages accepted by the client and applicable inspection authorities.

This project reinforces Lmart’s position as a qualified manufacturer for industrial gas and specialty chemicals applications, demonstrating the company’s ability to deliver equipment that meets international quality and certification standards.
