Abstract

The invention discloses a special lubricating oil for a compound nitrogen / hydrogen gas compressor, which is characterized by being prepared from the following raw materials in percentage by mass: 80% of mineral base oil BS120, 12% of modified castor oil, 3% of polyisobutylene, 3% of dibutyl ester, 1.95% of silicone oil and 0.05% of nitrogen gas. The method for preparing the special lubricating oil for a compound nitrogen / hydrogen gas compressor comprises the following steps: pre-inspecting the raw materials, quantifying, respectively adjusting, carrying out physical inspection, combinedly adjusting, carrying out chemical inspection, carrying out fine adjustment, inspecting on a platform, filtering, carrying out gas treatment, carrying out final inspection, and packaging. The special lubricating oil disclosed by the invention does not contain any element harmful to catalysts, has the advantages of favorable wear resistance, water resistance, ammonia resistance, ageing resistance and energy-saving effect, can be easily recycled and regenerated, and solves the problem of the adoption of an oil product substitute in the existing nitrogen / hydrogen gas compressor.

Description

technical field

[0001] The invention belongs to the technical field of lubricating oil, and in particular relates to a special lubricating oil for compound nitrogen-hydrogen compressors. Background technique

[0002] Nitrogen-hydrogen compressors are the core equipment in the synthetic ammonia industry. Since the 1970s, there has been no special lubricating oil for this equipment in my country. In order to solve the contradiction between supply and demand, the Ministry of Commerce proposed to the national nitrogen fertilizer manufacturers in 1972: " The oil used for nitrogen-hydrogen compressors can generally refer to the oil used for air compressors", and it is also pointed out: "Nitrogen-hydrogen compressors (360Kg / cm 2 ) can be lubricated with No. 24 cylinder oil" (excerpted from the "Petroleum Commodity Knowledge Manual" issued by the Fuel Bureau of the former Ministry of Commerce). The special lubricating oil for compressors is not listed in it. The air compressor oil a...

Embodiment Construction

[0026] The special lubricating oil for the composite nitrogen-hydrogen compressor of the present invention is formulated according to the mass percentage of the following raw materials: 80% of mineral base oil BS120, 12% of modified castor oil, 3% of polyisobutylene, 3% of dibutyl ester, 1.95% of silicone oil, Nitrogen 0.05%.

[0027] Its preparation process is as figure 1 As shown, the above raw materials are prepared according to the process steps of: pre-inspection-quantification-sub-adjustment-physical inspection-joint adjustment-chemical inspection-fine adjustment-platform inspection-filtration-gas treatment-final inspection-subpackaging. Among them, pre-inspection: inspection of various physical and chemical indicators of raw materials; quantification: on the basis of pre-inspection, each raw material is weighed according to the aforementioned ratio; sub-adjustment: each component and part of the base oil are blended into a mother liquor, and the temperature is 80 ° C. ...
