Abstract

Te invention discloses a petroleum distillation tower cleaning agent and relates to the technical field of petrochemical industry. The petroleum distillation tower cleaning agent is prepared from the following raw material components in parts by weight: attapulgite, ash wood, grapeseed oil, turpentine, paraffin, trisodium phosphate, sodium metasilicate, sodium hydroxide, walnut shell particles, N-N'-dihydroxyethyl coconut oil amide, wire-drawing powder, sodium sulfate ether, sea sand powder, an activating agent, an active auxiliary agent, a defoaming agent, ethanol and deionized water. The cleaning agent has strong dissolving and cleaning functions on petroleum chemical polymers such as oil coke, coke and tar in the petroleum distillation tower, can completely remove sediments and dirt attached to the wall of the distillation tower, does not generate corrosion and damage effects on the distillation tower, has excellent antirust effect and high cleaning efficiency, is safe and convenient and does not have toxic or side effects; and a proper amount of cleaning agent is added in the inner wall of the distillation tower and is completely contacted with the inner wall of the distillation tower, and the cleaning agent can be implemented by brushing and washing, has extremely high oil dissolving capability and can be repeatedly used.

Description

Technical field: [0001] The invention relates to the technical field of petrochemical industry, in particular to a cleaning agent for petroleum distillation towers. Background technique: [0002] The modern term of the distillation tower refers to the chemical equipment made of rare metal titanium and its alloy materials. It is a tower-type vapor-liquid contact device for rectification, also known as a rectification tower. There are two main types of plate towers and packed towers. According to the operation mode, it can be divided into continuous rectification tower and batch rectification tower. Steam enters from the bottom of the tower. The evaporated gas phase is in countercurrent contact with the descending liquid. During the two-phase contact, the volatile (low boiling point) components in the descending liquid are continuously transferred to the gas phase, and the less volatile (high boiling point) components in the gas phase are continuously descending. The closer...
