    Abstract: The invention discloses the design of an improved household solar still with enhanced output and high recovery. The output and recovery are enhanced by (i) aligning the top glass and basin so as to maximise the input solar radiation, (ii) using North-South reflectors in V trough configuration to further raise the incident radiation, (iii) employing metallic condensers on sides to maximise condensation efficiency, (iv) using suitably heated and cooled saline water by taking advantage of ambient temperature differential during a day and using such water as feed water and condenser water respectively. Use of detachable top glass assembly and teflon cork at the bottom allow for easy cleaning of the interior of the still and discharge of concentrate, respectively. The still is also demonstrated to be useful for other applications where, besides producing distilled water, the concentrate is a more value added product than the feed.

    Abstract: Although U S patent 8,182,784 teaches the recovery of potassium chloride from schoenite end liquor (SEL) using dipicrylamine as extractant, and consequently simplifies the recovery of sulphate of potash (SOP) from kainite mixed salt employing the scheme disclosed in U S patent 7,041,268, the hazards associated with this extractant have thwarted practical utilization of the invention. Many other extractants for potash recovery have been disclosed in the prior art but none has been found suitable so far for practical exploitation. It is disclosed herein that the bitartrate ion, and particularly L-bitartrate, precipitates out potassium bitartrate very efficiently from SEL with ca. 90% utilization of the extractant. In contrast, recovery of potassium bi-tartrate from sea bittern directly is relatively much lower. It is further disclosed that this precipitate can be treated with magnesium hydroxide and magnesium chloride to throw out magnesium tartrate with ca. 90% recovery while yielding a nearly saturated solution of potassium chloride which can be utilized for the reaction with schoenite to obtain SOP. It is further demonstrated that the magnesium tartrate can be treated with an appropriate amount of aqueous HCl and added into a subsequent batch of SEL to throw out potassium bitartrate once again which demonstrates the recyclability of the extractant. The overall loss of tartrate over a cycle was ca. 20% but the dissolved tartrate remaining in the K-depleted SEL and KCl solutions can be precipitated out as calcium tartrate from which tartaric acid can be recovered by known methods, curtailing thereby the loss of tartaric acid per kg of KCl to

    Abstract translation: 尽管美国专利8,182,784教导了使用二辛基胺作为萃取剂从白铁矿末端溶液（SEL）中回收氯化钾，从而简化了使用美国专利7,041,268中公开的方案从卡培酸盐混合盐中回收硫酸钾（SOP） 该提取剂阻碍了本发明的实际应用。 许多其它用于钾盐回收的萃取剂已经在现有技术中公开，但迄今为止没有发现适用于实际的开发。 本文公开了酒石酸盐离子，特别是L-酒石酸盐，从SEL中非常有效地沉淀出酒石酸钾。 萃取剂的利用率达90％。 相比之下，直接从海盐酸盐中回收酒石酸钾相对要低得多。 进一步公开，可以用氢氧化镁和氯化镁处理该沉淀物，以约 90％的回收率，同时产生几乎饱和的氯化钾溶液，可用于与白铁矿反应获得SOP。 进一步证明酒石酸镁可以用适量的HCl水溶液处理，并再次添加到随后的一批SEL中以再次排出酒石酸钾，这表明萃取剂的可回收性。 在一个循环中酒石酸的总体损失约为 20％，但残留在K-消耗的SEL和KCl溶液中的溶解酒石酸盐可以以酒石酸钙沉淀出，酒石酸可以通过已知方法从其中回收，从而减少酒石酸/ kg KCl的损失至<5g。 也证明了通过类似的方法，含有ca. 4％KCl可以浓缩至20-22％KCl，具有优异的酒石酸利用效率，并且该溶液也可类似地用于SOP制备。 含有其他阴离子如硫酸盐，硝酸盐，磷酸盐和碳酸盐的钾盐也可以由分离的酒石酸钾制备。
