Solid anti-scaling agent and preparation process thereof

Abstract

The invention discloses a solid antifouling agent, which is obtained by cementation of 40-60 weight parts of main antifouling agent and 40-60 weight parts of polymer cementing agent at high temperature, wherein the main antifouling agent is prepared from (by weight parts) HEDP 35-50, PAPE 30-45, sodium sulfonate 1-5, sodium molybdate 5-10 by chemical reaction. The solid antifouling agent has long-lasting drug action and high antifouling rate, effectively prevents fouling of equipments and pipes in petroleum processing process, and reduces injection times, thereby improving continuous production period of petroleum-processing devices, reducing labor and financial investment, and reducing production cost.

Description

technical field [0001] The invention relates to an anti-scaling agent in the process of petroleum processing, which is a chemical additive for preventing fouling of petroleum processing equipment, pipelines, etc.; the invention also relates to a preparation method of the anti-scaling agent. Background technique [0002] Scaling of oilfield water is similar to that of crude oil, and is an inevitable phenomenon in oilfield production. Scaling of petroleum processing equipment and pipelines has always been a major technical problem in the process of petroleum processing, because the scaling of equipment and pipelines will seriously affect the long-term operation and safe production of the device, and bring many hazards to production. For example, formation scaling will cause water injection pressure to increase and oil well fluid production to decrease, thereby affecting oil field production; pipeline scaling will cause production and safety issues such as blockage and localize...

Problems solved by technology

However, these antiscaling agents still have some defects, such as: metal salt antiscaling agents may have an adverse effect on the catalyst in the petroleum processing technology, and the catalytic action of the metal salt may also cause the generation of high polymers with metal salts as the core. Slagging and precipitation; the high temperature resistance of amine antiscalants is not good, and the antiscaling efficiency is not high, etc.
