Abstract

The invention belongs to the field of heavy oil additives, and more specifically is a heavy oil composite additive, which consists of the following components in parts by weight: 10-35 parts of demulsifier; 8-20 parts of surfactant; 10-20 parts of combustion enhancer 20 parts; 20~35 parts of stable dispersant; 3~15 parts of corrosion inhibitor; The main additive greatly dilutes the viscosity of the heavy oil and improves its fluidity, so the dispersibility after spraying from the nozzle is large, it is in full contact with the air, the combustion is complete, and black smoke is eliminated, which is beneficial to environmental protection; with the quality of heavy oil Add the additive of the present invention to the washed heavy oil based on the addition amount of 0-40ppm, the mass fraction of sodium is lower than 4×10-6, the mass fraction of potassium is lower than 0.25×10-6, the oil-water interface is clear, the sewage is colorless and transparent, It can achieve a good demulsification effect; the economic benefit is remarkable, and it can reduce the fuel cost of the user unit and the maintenance cost of combustion equipment such as boilers.

Description

technical field [0001] The invention belongs to the field of heavy oil additives, and more specifically relates to a heavy oil composite additive and provides a preparation method of the additive. Background technique [0002] The shortage of petroleum resources and the shortage of energy have been recognized all over the world. How to solve the shortage of energy has become a research topic of disputes among countries all over the world. The price of heavy oil is low, the source is wide, and it has a certain calorific value, so it is a main source of fuel. Heavy oil is also called residual oil, which is the residual oil after distillate oil is extracted from crude oil through atmospheric or vacuum distillation equipment, or the cracked residual oil extracted from the bottom of the high-temperature pressurized cracking evaporation tower, or a mixture of the two, or adding an appropriate amount A heavy petroleum fuel made from cracked residual oil. [0003] Because heavy oi...
