1. Petrochemical Applications and HT-BLOC Fully Welded Plate Heat Exchanger

The HT-BLOC fully welded plate heat exchanger is designed for high-temperature, high-pressure, corrosive, and leak-sensitive services. Compared with conventional shell-and-tube equipment, its fully welded plate pack offers high heat transfer efficiency, compact footprint, and reduced leakage risk. It can be used as a replacement or complement to traditional heat exchangers in petrochemical plants, natural gas processing, wastewater preheating, and waste heat recovery.

The equipment can adopt patented reinforced corner connections to improve the strength and welding reliability of titanium, nickel, and other special materials. Enhanced graphite gaskets can further improve sealing performance under high-temperature and high-pressure conditions, supporting stable long-cycle operation with complex media.

Light Hydrocarbon Station Waste Heat Recovery

In light hydrocarbon stations and related oil and gas processing units, waste heat recovery can reuse low-grade heat from process media, flue gas, or circulating streams to preheat feed, circulating water, or auxiliary process media.

Compact plate heat exchange equipment provides a large heat transfer area within limited plot space, making it suitable for energy-saving revamps and cascade heat utilization. Equipment selection should consider corrosion, pressure rating, pressure drop limits, and maintenance access.

Rich-Lean Heat Exchanger

In amine treating units for hydrocarbon separation, natural gas purification, and refinery gas treatment, the rich-lean heat exchanger transfers heat between acid-gas-rich amine and regenerated hot lean amine. This preheats the rich amine to reduce regeneration steam consumption while cooling the lean amine for the downstream absorber, making it a key energy-saving unit in the amine circulation system.

When HT-BLOC is used for rich-lean service, its fully welded structure helps address gasket aging, leakage, and media compatibility issues. The heat transfer coefficient can typically reach two to four times that of conventional shell-and-tube equipment, while the compact structure helps reduce footprint in revamp projects. Typical applications include natural gas desulfurization, decarbonization, dehydration, refinery gas sulfur recovery, and EO/EG chemical units.

Natural Gas Cooler

Natural gas coolers are used in natural gas treatment, purification, and post-compression cooling services, where pressure resistance, sealing reliability, and corrosion resistance are critical. The compact HT-BLOC structure provides efficient heat exchange in limited space and is suitable for continuous operation in gas stations and petrochemical units.

Materials such as stainless steel, titanium, 254SMO, and C-276 can be selected according to gas composition and cooling medium conditions. The fully welded structure also reduces risks associated with gasket aging and external leakage.

Crude Oil Cooler

In reforming, gasoline and diesel hydrogenation, aromatics, and atmospheric-vacuum distillation units, crude oil coolers, crude oil heaters, overhead condensers, and tower-bottom reboilers all require efficient heat transfer. HT-BLOC can be applied to high-temperature, high-pressure, and complex-media duties to improve heat recovery depth, reduce energy consumption, and optimize plant layout.

The fully welded plate pack eliminates leakage risks associated with rubber gaskets. Compared with traditional shell-and-tube equipment, HT-BLOC can significantly improve heat transfer performance and further reduce terminal temperature difference, supporting higher unit energy efficiency.

High-Salinity Wastewater Preheater

High-salinity wastewater preheating and heat recovery services are often accompanied by corrosion, scaling, and fouling risks. HT-BLOC can achieve efficient heat transfer with a small terminal temperature difference, helping recover usable heat from wastewater while reducing the maintenance burden associated with conventional gasketed plate heat exchangers in hot, saline environments.

Titanium, 254SMO, and other plate materials can be selected for complex and corrosive wastewater.
