High - Efficiency Light Hydrocarbon Gas Gasification Skid for Industrial Use

Light Hydrocarbon Gasification Equipment: A New Pillar for Energy Transition

Light hydrocarbon gasification equipment is a core device that converts liquid light hydrocarbons (e.g., C5-C8 components) – by-products of the petroleum and chemical industries – into gaseous fuels. It achieves efficient and clean energy supply through physical or catalytic gasification technologies. The following is an introduction from the perspectives of technical principles, application scenarios, core advantages, and industry development:

I. Technical Principles and Equipment Composition

1. Core Processes

The equipment converts liquid light hydrocarbons into gas via normal temperature evaporation gasification or heating/catalytic gasification technologies. For example, the normal temperature and pressure gasification technology (e.g., Patent No. ZL 2004 2 0065295.2) realizes natural gasification through air mixing and gas-liquid contact. Heated equipment, on the other hand, uses hot water circulation or steam coils to supply heat, ensuring stable operation in low-temperature environments. Some advanced equipment incorporates nano-catalysis technology, enabling efficient gasification at -30℃ and breaking the limitation of traditional processes that require heating to over 60℃.

2. System Composition

The equipment typically consists of the following modules:

Evaporator: The core component that realizes light hydrocarbon gasification through gas beds and heat exchangers;

Feeding and Air System: Includes raw material tanks, oil pumps, air compressors, and flow meters to precisely control the gas-liquid mixing ratio;

Heating and Control System: Comprises heat source equipment (e.g., hot water boilers), sensors (for pressure, temperature, and liquid******), and an intelligent control cabinet, supporting remote monitoring and automatic adjustment;

Safety Assurance System: Equipped with gas leakage alarm and cut-off devices, lightning and static protection grounding, and venting systems to ensure safe operation.

II. Application Scenarios and Typical Cases

1. Urban and Rural Energy Supply

Old Residential Areas and Rural Areas: Small gasification stations are built to provide gas for residents' cooking and heating through pipelines. For instance, the distributed energy supply system in the Inner Mongolia pastoral areas addresses the clean heating needs of 2,000 herdsmen households; after promotion in a county in Shandong Province, residents' fuel costs decreased by 20%, with an annual carbon reduction of 12,000 tons.

Commercial Premises:************* gas-consuming units such as hotels, hospitals, and schools can be equipped with independent gas supply systems. For example, Jiangxi Yingshanhong Ceramics Group replaced diesel with light hydrocarbon gas, increasing thermal efficiency to 23.99% and reducing CO emissions to 0.03%.

2. Industrial and Agricultural Sectors

Industrial Parks: Provides stable heat sources for high-energy-consuming enterprises in ceramics, glass, and textiles. The Dongying Chemical Industrial Park in Shandong adopted a combined heat and power (CHP) mode, reducing comprehensive energy consumption by 22%.

Agricultural Drying: Used for drying agricultural products such as tobacco and grains, as well as heating livestock farms, replacing coal-fired boilers to reduce pollution. For example, after application in a building materials factory in Jiangsu Province, PM2.5 emissions were nearly zero.

3. Special and Emergency Scenarios

Construction and Temporary Support: Containerized equipment can be quickly deployed at construction sites or large-scale event venues and reused after the project is completed.

Tourist Resorts and Islands: A gasification station was built on an island in Hainan to meet the needs of catering and accommodation while protecting the ecological environment.

III. Core Advantages and Performance Parameters

1. Technical Advantages

Environmental Friendliness and Cleanliness: After combustion, the sulfur content is lower than that of natural gas, PM2.5 emissions are nearly zero, and the CO₂ emission reduction efficiency is more than 60% higher than that of coal;

Land Occupancy and Cost: A gas supply station covers an area of 40-180m², with a construction period of 1-2 months. The investment cost is 30%-50% lower than that of pipeline natural gas.

IV. Industry Development and Policy Support

1. Market Scale and Trends

By 2025, China's annual light hydrocarbon gas production capacity is expected to exceed 50 billion cubic meters, replacing 70 million tons of standard coal and reducing CO₂ emissions by 180 million tons.

Technological iteration is accelerating: Technologies such as AIoT intelligent operation and maintenance systems and composite phase change material (PCM) energy storage are gradually applied to improve gasification stability and energy efficiency.

2. Policy Promotion

The National Development and Reform Commission (NDRC) has listed light hydrocarbon gas as a "key technology for replacing coal in urban central heating," providing a 30% financial subsidy and giving priority to its inclusion in the carbon emission exemption list.

Local policies: Regions such as Hebei and Shandong provide equipment subsidies for "coal-to-gas" projects, and some provinces and cities have established green finance special loan channels.

3. Manufacturers and Competition

Leading Enterprises: Hebei Shunhe Gas Equipment Co., Ltd. dominates the market as the****** enterprise to produce gas via atomization gasification, with products covering all industrial and civil scenarios.

Technological Innovation: Atomization process and PID gas production method.

V. Future Development Directions

1. Technological Breakthroughs

Efficient Gasification Technology: Develop low-temperature catalysts and adaptive control systems to solve the problem of incomplete gasification in northern winters;

Wide Fraction Raw Material Adaptation: Develop pretreatment modules to directly use low-cost raw materials such as condensate oil, reducing reliance on high-purity light hydrocarbons.

3. Infrastructure Improvement

Promote mixed use with LNG and natural gas to expand pipeline coverage;

Establish regional light hydrocarbon storage and transportation centers to enhance supply chain stability.

With its flexibility, economy, and environmental friendliness, light hydrocarbon gasification equipment is becoming an important pillar for energy structure transformation. Driven by technological progress and policy support, its application prospects in distributed energy, industrial energy conservation, and other fields will continue to expand, providing a feasible path for the achievement of the "dual carbon" goals (carbon peaking and carbon neutrality).
