Follow on Google News | Treating Process of Drilling Waste and How to achieve Zero Discharge of drilling wasteDrilling waste management is a hot topic from last year. More and more EPC company try to source professional equipment and personnel on the potential projects with large profit. It is said the capacity of the drilling waste market can reach 17
By: Hebei GN Solids Control Co., Ltd. GN Solids Control is professional drilling waste management equipment manufacturer; No.1: Source of drilling waste No. 2: Necessary drilling waste management equipment No.3: Treating process of drilling waste and How to achieve Zero discharge of drilling waste http://www.gnsolidscontrol.com/ No.1: Source of drilling waste Oil pits (there are many oil pits and waste management service company are trying to do land remediation to original state which means they will treat the crude to get it back to its crude status, soil back to soil and water to be recovered): Oil pit case from Iraq drilling waste management market: a.) There are over 120 oil pits to be treated. b.) More than 60% are emptied from crude and what is left is sludge and soil to be treated. c.) Average sizes are 100 miters in length, 70 miters in width and 5 miters in depth. d.) We will be dealing with all of them, the ones that have sludge and soil left and the ones that are still filled with crude. e.) The base of all pits is earthen. No concrete nothing else but earthen. d.) Our task is to treat all pits and remediate the land to original status where we will plant them with trees. Refinery waste: Most of it is waste water, sludge, and the usual refineries waste ingredients. The refinery waste will be first recovered from large ponds and for those ponds to be remediated to original status where we will plant them with trees. Storage tank sludge: The tanks are yet to be calculated in terms of number and storage capacity. However, they are estimated to exceed the 50 tanks mark. Drilling waste from oil based mud drilling operations. The assessment is yet to be conducted No.2: Necessary drilling waste management equipment Vertical cuttings dryer: this is the first stage of OBM drilling waste management. It can separate the big waste solids particles above 5 to 100 microns. GN vertial-G dryer with samilar design to CSI dryer or Swaco dryer, have got good test report from CNPC jobsite. Decanter Centrifuge: this is the second stage of OBM drilling waste management. It can separate the fine solids above 2-5 microns. GN decanter centrifuge with similar design to Derrick DE1000 and Swaco 518HV, have got good working performance feedback from many customers. Necessary accessories equipment: Screw conveyor for transfer drilling waste, feeding pump for centrifuge, sludge tank to storage drilling waste etc. No.3: Treating process of drilling waste and How to achieve Zero discharge of drilling waste Firstly, the drilling waste should be pumped or transfered to vertical cuttings dryer; Secondly, the drilling waste should be treated by high speed decanter centrifuge http://www.gnsolidscontrol.com/ Thirdly, the drilling liquid waste from vertical cuttings dryer and decanter centrifuge can be collected together by storage tank; the drilling solids waste from vertical cuttings dryer and decanter centrifuge can be colleted together by sludge skip.( or cuttings box ) Fourthly, the drilling liquid waste can be treated by Oil/water separator and get pure water & pure oil ; the drilling solids waste can be treated by Thermal Desorption Unit (TDU) to get pure oil & dry solids.
