Special alkylbenzene sulfonate surfactant for ASP flooding

Special alkylbenzene sulfonate is a product obtained from alkyl benzene with multi-carbon chain

Product Introduction

?Special alkylbenzene sulfonate is a product obtained from alkyl benzene with multi-carbon chain, sulfonated and then special treatment. It has strong emulsifying and dispersing ability for crude oil, fuel oil and various petroleum products. The important application of special alkylbenzene sulfonate is to be used as oil displacement agent and oil emulsifier. After proper blending, it can form ultra-low interfacial tension with crude oil, spontaneously dissolve crude oil to form a stable solution, and maintain certain dissolving emulsification effect, with strong oil displacement ability.

Product Property

The surfactant used in oil displacement has a certain selectivity to the properties of crude oil, and the structure of the surfactant used varies with the properties of different oil fields. The molecular structure of surfactants should match the crude oil components to achieve ultra-low interfacial tension and higher oil displacement efficiency. In order to meet the needs of different oil fields, BHS -100, BHS -200 and BHS -300 series have been developed.
The property of the product is as follows:
Table 1：The property of the special alkylbenzene sulfonates
Item No. Active Content（％） Appearance pH
BHS -100 50±2 Light yellow liquid 11-13
BHS -200 50±2 Light yellow liquid 7-10
BHS -300 50±2 Light yellow liquid 7-10

Product Features

?When the sulfonate surfactant is used alone, under low dosage can form an ultra-low interfacial tension with the crude oil under weak or strong alkali condition, improve the performance of the oil displacement and achieve good oil displacement effect. It can also be compounded with alkyl benzene sulfonate, petroleum sulfonate, a-olefin sulfonate, petroleum carboxylate, biosurfactant and amphoteric surfactant.
The BHS surfactant has the following remarkable features:
(1) Strong adaptability
(a) Applicable to heavy oil and high viscosity oil. For commonly used sulfonate surfactants are generally applicable to the crude oil whose density is lower than 0.904g/cm-3 and the viscosity is lower than 3.0x10-2Pa.s.
(b) High temperature and salt resistance. Commonly used sulfonate surfactants are generally not suitable for high salinity reservoir conditions for their poor performance of salt-resistance.
(c) Single agent can be used for a wide range of crude oil. Commonly used sulfonate surfactants can only be used for only a few kinds of crude oil, and the composition should be changed to adapt to different crude oils, or use it in combination with other surfactants, which increases the investment in ground equipment and hard to promoted as commercial products.
(2) Good compatibility.
(a) It is suitable for ASP flooding system under weak alkali condition as well as strong alkali condition.
(b) Compatible to many kinds of polymer. Even when high concentration and ultra-high molecular weight polymer was used, the effect on the interfacial tension between the system and crude oil is small and can reach a wide ultra-low range.
(c) Compatible to wide range of alkali concentration. It can adapt to the alkali concentration range from 0.2% to 0.8%, or 0.2%-1.2% for some oilfield under strong alkali condition; from 0.6% to 1.6% under weak alkali condition. However, heavy alkyl benzene sulfonate surfactants can be only used when the concentration of alkali is 0.9%-1.3% for their poor ability of salt-resistance, and petroleum sulfonate performs even worse.
(3) High performance-price ratio
(a) It can reach good results under low dosage condition (0.1%). Low adsorption, high activity, good emulsification, wide range of use.
(b) The product has good solubility and high flash point, which reduces the cost of ground engineering investment and operating.

Product Application

This series of surfactants have higher activity in the lower concentration range of 0.05%-0.3% (mass fraction), which can be determined according to site conditions.

Storage

Pay attention to ventilation and store at room temperature.

Dicyandiamide Formaldehyde Resin

Dicyandiamide resin decolorizing flocculant is a highly efficient decolorizing coagulant

Overview

Dicyandiamide resin decolorizing flocculant is a highly efficient decolorizing coagulant, which has obvious decolorization and COD reduction effects. Mainly used in the treatment of industrial wastewater such as textiles, printing and dyeing, papermaking, pigments, mining, inks, landfill leachate, etc., can also be used for the decolorization of high-chroma wastewater from dye plants, and can be applied to wastewater treatment such as reactive, acidic and disperse dyes. . This product can also be used as paper reinforcing agent, sizing agent and charge neutralizing agent.

Physical Performance

Items Index Test Method
Appearance Colorless to yellowish viscous liquid Visually inspect and stir
Solid Content（%） 50±2 Weight
Viscosity（cps） 30~130 Brookfield Viscometer
pH 4.5~6.5 pH meter

Product Characteristics

1. Strong ability to decolorize and remove COD and BOD
2. Faster and better flocculation sedimentation
3. No pollution (no heavy metal ions)

Instructions

1. Dilute this product 10-50 times with clean water, add it directly to the wastewater and stir it evenly. After sedimentation or air flotation, the decolorized clear liquid can be obtained. It is better to control the pH value of the waste water at 7~10.
2. When the chroma and COD of the wastewater are high, it is advisable to use the decolorizer in combination with inorganic flocculants such as polyaluminum chloride and polyiron for treatment, which can reduce the treatment cost. The adding method, proportion and order can be determined by mixing experiment and wastewater treatment process.
3. Keep the system as stable as possible during operation to make it operate under the best conditions.
4. The place and mixing speed of the agent in the system should be carefully selected. It is necessary to ensure that it is evenly mixed with the material, but also to avoid the breakage of the floccules.

Packaging

Dicyandiamide formaldehyde resin products are sealed in 200kg plastic drums, which can also be determined according to user needs. The shelf life is 2 years.

Precautions

It should be stored in a cool, ventilated and dry warehouse. If there is stratification or whitening when stored at low temperature, it will not affect the effect after mixing. The recommended storage temperature is 5~30℃.
