摘要
针对因气田污水中大量的Ca2＋、Mg2＋、Fe2＋、HCO3-等离子及一定量的SO42-和溶解的CO2、H2S气体造成甲醇回收装置塔底水热交换器、原料水热交换器等管束内外表面结垢、管束腐蚀穿孔、管束与管板焊接密封面渗漏等问题,对新热交换器管束进行TH-901涂层防腐处理,对已发生渗漏的热交换器管束进行部分或全部更换时也采用TH-901涂层进行防腐处理,取得了较好的效果。
As a developing country,China attracted most of the foreign direct investment（FDI） in the world.Although the percentage of agricultural FDI is not large,approximately 2%,we should not ignore the effect of agricultural FDI on domestic agriculture security.This paper chooses the time series data from 1997 to 2009 to conceive a simultaneous equation model,used Two Stage Least Square（2SLS） and Ordinary Least Square（OLS） to estimate the crowding-out effect of agricultural FDI on domestic investment and employment.The result shows that a 1% increase of agricultural FDI will crow out 0.2% domestic investment and 0.01% employment.Finally,based on the view of crowding-out effect on domestic investment and employment,this paper makes some suggestions about the effect of foreign direct investment on domestic agriculture security.
