Abstract:
A solid antiscalant agent and a preparation method therefor. The solid antiscalant agent comprises a main antiscalant agent and a consolidating agent, the main antiscalant agent and the consolidating agent being in a ratio of 1:1. The main antiscalant agent comprises, in parts by weight: 35-50 parts of hydroxyethylidine diphosphonic acid, 30-45 parts of polyhydric alcohol phosphate ester, 1-5 parts of sodium hexametaphosphate, and 5-10 parts of sodium molybdate; and the consolidating agent comprises, in parts by weight: 3-5 parts of alum, 20-30 parts of epoxy resin, 7-10 parts of polyamide, 13-15 parts of epoxy diluent, and 17-20 parts of silane coupling agent. The solid antiscalant agent has long efficacy release period and high anti-scaling rate. After being used, the agent can prevent equipment and pipelines from scaling in a petroleum processing process and reduce filling number of times, so that a continuous production cycle of a petroleum processing device is improved and labor and financial investments are reduced, and thus production cost is reduced.
