Mineral Hydrocarbon Oil (MHO)
Mineral Hydrocarbon Oil (MHO) refers to a class of petroleum-based oils derived from crude oil refining.
Definition:
MHO is a complex mixture of hydrocarbons, primarily paraffinic and naphthenic, with varying carbon chain lengths.
Properties:
1. Density: 0.80-0.95 g/cm³
2. Viscosity: 10-100 mm²/s (at 40°C)
3. Flash point: 100-250°C
4. Pour point: -30 to 0°C
5. Solubility: Miscible with most organic solvents
Types:
1. Light Mineral Oil (LMO)
2. Medium Mineral Oil (MMO)
3. Heavy Mineral Oil (HMO)
4. Mineral Hydraulic Oil (MHO)
5. Mineral Turpentine Oil (MTO)
Uses:
1. Lubricants (industrial, automotive)
2. Hydraulic fluids
3. Cutting oils (metalworking)
4. Cleaning agents
5. Cosmetics and personal care products
Specifications:
MHO meets various national and international standards, including:
1. API (American Petroleum Institute)
2. ASTM (American Society for Testing and Materials)
3. ISO (International Organization for Standardization)
4. DIN (Deutsches Institut für Normung)
Manufacturers:
1. ExxonMobil
2. Shell
3. Chevron
4. BP
5. Total
Benefits:
1. Wide range of viscosities
2. Good thermal stability
3. Low volatility
4. Compatibility with various materials
Safety and Handling:
1. Flammable and combustible
2. Skin and eye irritant
3. Use protective equipment (gloves, goggles, mask) when handling
Environmental Impact:
1. Potential water pollution
2. Soil contamination
3. Air pollution (VOCs)
