Description

A separator for filtrating in filter core

Technical Field

The utility model relates to a marine oil and natural gas engineering equipment field especially relates to a separator that is arranged in filtrating of filter core.

Background

The filter is widely applied to offshore petrochemical facilities, and is used for filtering process media such as crude oil, condensate oil, diesel oil, production water, triethylene glycol and the like. The filter element can not meet the filtering requirement after being saturated by the adsorbed substances and needs to be replaced regularly. After a large amount of filter cores are dismantled in the current offshore facility, filtrate is difficult to separate from the filter cores, and toxic and flammable filtrate seepage often occurs in filter core storage, transportation and waste treatment, so that the hidden troubles of poisoning, fire and environmental pollution are caused.

The diesel oil filter element of the fuel oil generator is widely used in offshore oil and gas facilities, the filter element is generally a PP filter element, after the filter element is used to reach saturation, a large amount of diesel oil is retained in the replaced filter element, the residual diesel oil in the filter element is easy to spontaneously combust in high-temperature days in summer, and fire hazard exists in waste treatment.

Crude oil filter core is the filter core kind that must use in the offshore oil field treatment process, and this filter core is mostly accurate line winding formula, because crude oil viscosity is high, and crude oil is difficult to separate from the filter core in the filter core of pulling down, causes a large amount of crude oil to be detained, and the filter core can't continue to use, because crude oil filter core changes frequently, and the filter core consumption is huge annually.

The filter element of the triethylene glycol activated carbon filter is a filter element type which must be used in the offshore gas field process, the filter element is tightly compacted and filled with activated carbon, and the outer surface of the filter element is fixed by a stainless steel filter screen. When in use, the triethylene glycol solution reaches the center of the filter element from the outside of the filter element through the active carbon porous structure and flows out, so that the filtration of triethylene glycol is realized.

After the activated carbon filter element is replaced, a large amount of triethylene glycol is retained in the filter element due to high viscosity and high specific gravity of the triethylene glycol, and a large amount of triethylene glycol is lost due to the fact that the filter element is large in size and large in amount of residual triethylene glycol and cannot be recovered in time.

In conclusion, there are many kinds of offshore oil and gas field facilities which need to use filter elements, and the filter elements are easy to absorb filtrate or the filtrate has the characteristics of viscosity and the like, so that a large amount of filtrate is retained in the replaced filter elements. The following consequences will result. Firstly, during the filter core waste disposal process, the extravasation of the filtrate causes fire, personnel poisoning and environmental pollution. Secondly, a large amount of filtrate is left, and the filter element cannot be thoroughly cleaned and recycled, so that a large amount of waste of the filter element is caused, and the cost is increased. And thirdly, more filter liquor is retained in part of filter cores, filter liquor is greatly lost due to filter core replacement, medium loss is increased, the operation efficiency of a process system is low, and the cost is increased.

In order to avoid the above consequences, simple gravity settling is adopted for liquid separation treatment on the filter element with the condition. After the filter element is replaced, the filter element is temporarily stored in the simple container, and liquid separation is realized by the gravity of liquid drops. The method has the following disadvantages that firstly, the separation time of the filtrate is long, the separation effect is poor, the filtrate can not be completely removed, the hidden danger of filter element treatment is still large, and the filter element can not reach the condition of recycling; secondly, the filtrate in the separation process is easily polluted by dust impurities in the environment, and the separated filtrate can not meet the requirement of recycling.
