| Technique：Optimizing and revamping technology for SDP |
| Country：[CN] |
Application Domain：[Technologies For Pollution control] |
| Brief： |
Pre-treating for water inflow
Most current SDPs in refineries use oil removal—floatation—biotreatment process. This process has high requirements for the quality of water inflow according to SH 3080-1999 Standards for water feeding and water discharging in petrochemical industry. Without pre-treatment, the water inflow for disposal plant cannot meet the standard.
For most refineries, the reason that their SDP cannot perform full function lies in the fact that the high waste content water, such as waste lye, sulfur and nitrogen containing wastewater, wastewater from SDP sludge unit, high concentration wastewater from oil tank is not pre-treated.
With FRIPP’s technology, the above wastewater can be pre-treated so that they meet SH 3080-1999 water standard before secondary bio-processing.
Revamping of surface aeration pool
The surface aeration pool of refinery SDP has man defects in not only water inflow and aeration modes, but also sediment and water discharging, resulting in low cleaning efficiency and large sludge loss. Besides, it cannot remove nitrogen-containing wastes.
In order to increase the capacity of SDP and realize qualified discharging, FRIPP developed the revamping technology for surface aeration pool by transforming the operation mode of surface aeration pool from co-building to SBR so that the COD, ammonia nitrogen, petroleum components, sulfides and volatile phenols in discharging water meet the GB 8978-96 (Standard for comprehensive wastewater discharging) and realizing real wastewater cleaning and qualified discharging.
Automatic monitoring/controlling system
Limited by sampling and analyzing conditions, it’s impossible to completely prevent high concentration wastewater from affecting SDP. A solution besides strengthening pre-treatment for wastewater and regular management of the plant is to install an automatic monitoring system for water quality and quantity at the water inflow point of SDP so that the quality and quantity of wastewater can be real-time monitored. The parameters for water quality are pH, COD, petroleum components, suspended solids, temperature, and etc. The accuracy of the controlling equipment can be a little lower because it is only for process control. With this system, it is possible to automatically transfer wastewater that is not qualified in quality or quantity to adjustment pool. When the quality and quantity of wastewater is back to normal, the system is automatically changed back to normal operation and wastewater in the adjustment pool is mixed with untreated wastewater and resent back to SDP. Through the above practice, we can make sure that the SDP is under normal operation with process and control methods.

| Technique：Treatment of Odor pollution from petrochemical SDP |
| Country：[CN] |
Application Domain：[Technologies For Pollution control] |
| Brief： |
Odor pollution from refinery SDP is one of the focuses of refinery personnel, habitants near refinery and the environmental protection departments. The odor pollutants released by SDP are ammonia, hydrogen sulfide, organic sulfide, volatile hydrocarbons and etc. These substances have low odor threshold and cause great harm to people’s health. Their discharging is strictly limited according to GB 14554-93 (Discharging standard for odor pollutants) and GB16297-1996.
FRIPP has been engaged in the study and treatment of odor pollution. It has cooperated with several companies and successively carried out Pilot scale catalytic combustion test for odorous gases from oil separator under 40000h－1 and temperature 250℃. The removal of total hydrocarbon can be over 97% and the purified gases meet the GB16297-1996 and with no unpleasant odor. Pilot scale activated carbon adsorption test for odorous gases from surface aeration pool under LHSV 1500h－1(desulfurizing bed) for 100 days. The removal of the major pollutant, methyl mercaptan remained at 98%～100%. Under on-site conditions, the maximal sulfur containing capacity can be 2%～3%（W）.
Bench scale bio-packing column sweetening test for odorous gases from blow aeration pool. Over 80% of benzene series compounds and organic sulfur compounds and over 98% hydrogen sulfide can be removed.
At present, a commercial catalytic combustion test for odorous gases from oil separator is being carried out in a refinery and a pilot scale bio-sweetening test for treating odorous gases from aeration pool is also under way.

| Technique：Catalytic combustion for waste gases from PET production |
| Country：[CN] |
Application Domain：[Technologies For Pollution control] |
| Brief： |
The production of PET (bis-2-hydroxyethyl terephthalate) also produces waste gases such as aldehyde, 2-methyl-1,3-dioxolane, glycol and etc which if directly vented, will exceed the limit stipulated by GB16297－1996 and severely endanger the health of the people working around.
At present, PET plants generally use burning and water absorption to treat PET waste gases, which, however, is not satisfactory due to considerations such as system pressure balance, safety, lower pollutants removal, secondary pollution, and etc.
FRIPP, JICA and a domestic refinery have developed the water absorption-catalytic combustion process and carried out the pilot test.
With water absorption, glycol can be effectively removed and the total hydrocarbon concentration in waste gas is uniform so that the temperature of reactor outlet is stable. In catalytic combustion process, the catalyst operated for 95 accumulative days without showing activity loss under LHSV ,40000h－1 ; reactor inlet temperature 250℃. The pressure drop along catalyst bed is 30～38Pa/cm bed height.
The pilot test of the combined process showed that, treating PET waste gas with water absorption—catalytic combustion combined process under proper conditions, the total hydrocarbon concentration and aldehyde concentration are both within the limit of the national standard. The purified gas has no unpleasant odor.
This process is now under commercial test.

SO2 of refinery mainly comes from furnace flue gas of power plant, FCC/RFCC regenerator flue gas and tail gas from Claus sulfur recovery unit.
FRIPP has studied sulfur-removing unit such as 90,000m3/h spray column magnesium method for flue gas desulfurization, seawater washing for flue gas desulfurization, 12,000m3/h Venturi—water membrane for dust removing and desulfurization. All these studies have gotten satisfactory results.

| Technique：Environmental Impact Assessment (EIA) |
| Country：[CN] |
Application Domain：[Technologies For Pollution control] |
| Brief： |
FRIPP has been awarded the Class A Certificate for EIA (Environmental Impact Assessment) by SEPA (State Environmental Protection Administration). FRIPP has a specialized department for EIA and a group of technical personnel engaged in EIA. So far, there are 12 people who have passed the examination and granted EIA On-the-job Training Certificate issued by SEPA and Environmental Protection Administration (EPA) of Liaoning Province respectively.
Since 1980s, FRIPP has finished EIA for 30-odd large and medium scale national/ministerial construction projects. The EIA reports have passed appraisal by experts of SEPA and local EPA and provided technological support on environmental protection of the projects.
In 1999-2000, FRIPP, in cooperation with EXXON Singapore Yinglian Company, Liaoning Engineering Exploration Institute, and Jinzhou Petrochemical Company, carried out EIA for Jinzhou Jinglian Lubricant Additives Company (co-owned by EXXON Singapore Yinglian Company and Jinzhou Petrochemical Company) fully according to the procedures and standards of EPA and ASTM, which is the first time in China. The EIA result was accepted by both sides, which showed that FRIPP’s EIA activity has expanded from Governmental Environmental Protection to commercial environmental protection area.
