1. surfactants for recoveries of viscous crude oils
For specially thick crude oil ,we have to use surfactant to improve the thermal recovery performance, this surfactant is heat resisting foaming agent.
2. surfactants for recoveries of waxy crude oil
In the production of waxy crude oil, it is necessary to prevent and remove wax frequently. The commonly used oil-soluble surfactants are petroleum sulfonates and amine surfactants .
3. surfactants for modifing clay stability
Stabilizing clay include two aspects:preventing clay minerals expansion and preventing clay mineral particle migration.To prevent clay expansion mainly use amine salt,quaternary ammonium salts,pyridine salt, imidazoline salt ,etc.
4. Surfactants for acidification measures
To improve the acidification performance,it is necessary to add variety of acid solution. Generally use fatty amine hydrochloride, quaternary ammonium salts, non-ionic anionic surfactant as foaming agent, which can slow down corrosion and deep acidification
5. Surfactants for fracturing measures
6. Surafactants for profile control and water shutoff measures
7. Water treatment surfactants
Mainly use amine salts, quaternary ammonium salts, such as BKC, DDAC,etc.The purpose of water treatment include six aspects, corrosion inhibition,scale prevention,oxygen removal,oil removal and solid suspended matter removal.Therefore, it is necessary to use corrosion inhibitor,scale inhibitor,fungicides,deoxidizer, oil remover and flocculant agent.

With the number of people involved in public health incidents in India reaching new highs, the demand for palm oil for terminal consumption has fallen sharply, resulting in insufficient demand for palm oil imports. The impact of public health incidents in China is gradually decreasing, and its demand for palm oil is expected to increase, but the recovery is also gradually increasing, and its speed is relatively slow. However, it is worth noting that the palm oil harvest in the main palm oil producing areas has been reduced due to the dry weather in the middle of the year. In addition, the May holiday and some palm orchards and crushing plants in Sabah have suspended production due to public health incidents and due to the reduction of workers. And logistics and transportation issues, palm oil production has been affected. Market participants continue to pay attention to whether the production and export situation can alleviate the pressure of inventory growth in the main producing areas, especially Malaysia.
In the near future, it is necessary to pay attention to the fundamental data of Malay palm oil published by MPOB and the changes in the country's control measures related to public health incidents. Recently, Indonesia has begun to consider how to promote the B30 plan. The news will also boost palm oil, but it is expected to reflect only the short-term market. The continued low crude oil prices will continue to affect the production of palm oil-based biodiesel. On the other hand, after the palm oil price gradually approached the cost, the pressure on the cost of its plantations gradually increased, and there was a willingness to curb the decline. If the fundamentals do not have significantly better-than-expected bearish data, it is expected that palm oil prices will fluctuate slightly in the near future. But with the later production growth, prices will again face downward pressure. From May to June, the volatility of palm oil prices will remain low and fluctuating.
From the perspective of the domestic palm oil market, the volume of palm oil cargo transactions has increased recently, and the supply will increase in the later period, but at the same time, domestic demand has also improved. However, we need to pay attention to the recent soybean crushing situation. At present, with the increase of soybeans arriving in Hong Kong, the crushing volume has been maintained at a relatively high level. Soybean oil stocks are expected to grow, and soybean oil prices will also be under pressure in the later period, which will also cause palm oil prices to rise. Inhibition. Therefore, the domestic palm oil market also lacks a strong support for price increases, and it is expected to follow the price fluctuations of the main producing countries.

On the morning of May 10th, the Department of Environmental Protection and Chemical Engineering held the first Skills Festival and "Penny Cup" Chemical Professional Skills Competition Commendation Conference in the lecture hall on the second floor of the library. Zhang Yingliang, deputy director of the Department of Environmental Protection and Chemical Engineering, and You Weijiang, deputy general manager of Shandong Paini New Materials Co., Ltd. attended the meeting.
First of all, Comrade Zhang Yingliang would like to extend his warm congratulations to all the students who have achieved excellent results in the competition, and also express heartfelt thanks to Shandong Paini New Materials Co., Ltd. for their support and help in this competition.
Winning student representative Wang Wenting made a speech, and he said that being able to achieve today's results is inseparable from his usual efforts. He is determined to study harder in the future, to train himself into a skilled person with "exquisite skills, hard work style, and high efficiency", and to forge himself into a new youth worthy of the task of national rejuvenation.
Teacher Meng Xianqi from the referee team made a technical comment on the competition. He pointed out that during the competition, the students were well prepared and calmly challenged, with a series of skill operations skillfully and calmly, and their performances were different. I hope that the students will learn from each other, learn from each other's strengths, stay arrogant, modest and prudent, make persistent efforts in future studies, continue to study hard, and effectively improve their own skills.
Deputy General Manager You Weijiang said that this competition closely meets the needs of local chemical companies, thus setting up a platform for "integration of production and education" and "school-enterprise cooperation". The skill level and mental outlook of the teachers and students of your department have been strengthened. Shandong Paini New Materials Co., Ltd. is determined to continue to build a comprehensive strategic partnership with your department.
